The main materials of clean booth directly affect the cleanliness and effect of clean booth. Whether the maintenance is proper directly affects the service life of clean booth.

 

 What materials are used in clean booth: 

1. There are generally three types of frame materials for clean booth: stainless steel square tubes, iron square tubes, and aluminum profiles.

2. There are generally three types of materials for the top of clean booth: stainless steel plates, cold-rolled steel plates sprayed with plastic, anti-static mesh curtains, and organic glass.

3. For the clean air supply part, FFU laminar flow hoods (FFU fan filter units) are generally selected.

4. The enclosure materials of clean sheds generally include: anti-static curtains, (anti-static) organic glass.

The functional definition of the design concept of clean booth has mentioned that "controlling the main production process in a smaller environment is also a choice for clean booth design." In fact, this is the application concept of clean booth, with low investment and control of the main process. Since the control point is higher, the cleanliness level of the clean work booth is generally designed to be very high, generally ISO level 5 and level 4, and a few use level 6.

 

 

Clean booth is an air purification equipment for local high clean environment. Clean booth is mainly composed of box, fan, primary air filter, damping layer, lamps, etc., and the outer shell is sprayed. Clean booth can be hung or supported on the ground, with compact structure and convenient use. It can be used alone or connected in multiples to form a strip-shaped clean area.

 

Clean booth is generally referred to as clean booth, dust-free room, etc. Generally, film enclosure is used, so it is more appropriate to call it clean booth. It is also most appropriate to understand it as clean booth if it is not polluted.

Nowadays, many companies need to produce products in a clean room, such as large food production and processing and electronics production factory. Therefore, many companies are using clean room. The reason why clean room can be dust-free is mainly because a lot of high-tech purification equipment was installed in the clean room during decoration.

 

 

1. The air inlet system of clean room must be installed filter box, and a central purification air conditioner (the central purification air conditioner must be divided into three filter sections: primary efficiency /medium efficiency/high efficiency) with a high-efficiency air supply port at the end. It's necessary to install a purification booster box if need.

2. the return air system of clean room must be installed, including a return air outlet, a pre filter, and a middle filter return air box.

3. Enter the buffer zone before entering cleanr room. Electronic interlocks are installed on the buffer zone door, and clean storage cabinets and air fresheners are placed in the changing area. People and goods entering the clean room, must pass through the air shower, cargo shower room, and use pass box to mainly transfer small items.

4. In the clean room, vertical clean bench, laminar flow hood (FFU), clean booth (removable clean booth) and self-purifier should be installed in some places that need to reach level 10-1000. Laser dust particle counter for measuring the cleanliness of clean rooms.

5. The clean room build should be designed with observation windows to facilitate visits.

 

 Clean room equipment： 

1、Air shower, changing room and clean room are the three basic components of the workshop purification system. The air shower is a passage in and out of the clean area. The high-speed clean air jetted out can effectively and quickly remove dust and bacteria carried by the human body. The clean room uses interlayer color steel plates to isolate the space and walls, the upper color steel ceiling is suspended, and the floor is paved with epoxy resin.

2、The most important role of air purification equipment in a clean room is to control the cleanliness, temperature and humidity of the atmosphere that products are exposed, so that products can be produced and manufactured in a good environmental space. This space is called a clean room.

3. According to the clean room management regulations, the dust-free purification level is mainly determined based on the number of particles per cubic meter of air that are greater than the classification standard. But for optical structures, a small dose may produce a very large amount, so air purification equipment is needed to build in clean room.

 

 

The above content is the purification equipment that needs to be used in the clean room. Different purification levels have different requirements for purification equipment. This mainly depends on the production needs of each enterprise. 

 

Injection-molded magnetic components offer several advantages over traditional magnets. They resist rust more effectively and maintain very precise sizing. Additionally, they can be manufactured into a wide variety of shapes. These parts are produced using specialized molding techniques that combine materials like NdFeB and Ferrite, making them highly versatile for many industries. ZOYN is a leader in this field, providing solutions that meet demanding requirements.

 

Metric/Aspect	Data/Value
Global Market Valuation (2024)	USD 2.5 billion
Projected Market Valuation (2033)	USD 4.2 billion
CAGR (2026-2033)	6.5%

 

Injection-molded magnets provide the advantage of speeding up production and reducing assembly steps. This is why many manufacturers prefer to use them today.

 

Key Takeaways

• Injection-molded magnetic components give designers lots of choices. Makers can make complex shapes that help products work better. This also means fewer steps to put things together.

• These magnets use different materials and binders. This lets makers pick the best mix for strength, heat resistance, and toughness. They can choose what works best for each job.

• Injection molding keeps magnets safe from rust and damage. This helps them last longer and work well in hard places like cars and medical tools.

• The process makes parts with exact sizes and smooth surfaces. This saves time and cuts down on waste compared to old ways of making magnets.

• Injection-molded magnets cost less to make. They can be made quickly and in large numbers. It is easy to add them to other parts. This helps companies make better products faster.

 

Key Advantages

Design Flexibility

Injection-molded magnetic components give a lot of design freedom. Manufacturers can make shapes that are hard to do with other methods. They can create thin and light parts. Many functions can be put into one part. This helps new ideas in cars and electronics.

• You can make tricky shapes, like multi-pole inner magnetic rings and sensor housings.

• Overmolding and insert molding let you mix magnets with metals or plastics in one piece.

• Engineers can change how magnetic particles are spread and lined up, so the magnet works just right.

 

ZOYN’s special molding lets them make parts with cool shapes and features. This helps customers bring new ideas to life fast.

This freedom in design means fewer steps and parts. It makes things faster to build and saves money. In cars, these magnets help sensors and actuators work well. In electronics, they make small connectors and speakers possible.

 

Material Options

Injection molding works with many magnetic and polymer materials. This means makers can pick what fits their needs best.

 

Material Type	Examples / Grades	Key Properties / Features	Application Temperature Range
Magnetic Materials	Ferrite, NdFeB, SmCo, SmFeN	Different magnets have different strengths and shapes. Bonded magnets are not as strong but can be made in cool shapes.	-40°C to 160°C
Polymer Binders	Nylon 6 (PA6), Nylon 12 (PA12), PPS	PA6 and PA12 flow well, cost less, and have medium strength. PPS can take more heat, does not burn easily, and is stronger.	-40°C to 160°C

 

Makers choose materials for the right strength, heat, and toughness. PA6 and PA12 are good for many uses and save money. PPS is better if you need more heat resistance. With these choices, magnets can work in micromotors, printer rollers, and car parts.

 

Mixing different materials in one step is a big plus. It lets engineers control how the product works.

 

Customization

Customization is a big reason people like injection-molded magnetic components. The mold decides the final shape and size. This makes it easy to make special parts again and again. After molding, machines magnetize the parts to get the right direction, even for multi-pole magnets.

Manufacturers can join magnets with other parts in different ways:

• Insert molding: Puts a magnet in the mold, then covers it with plastic to hold it tight.

• Overmolding: Covers the whole magnet, keeping it safe from tough places.

• Ultrasonic welding: Uses sound to stick two plastic parts with a magnet inside.

• Snap-on and screw fastening: Uses clips or screws to keep magnets in place.

Extra things like grooves, steps, or covers help keep magnets safe during and after molding. Overmolding and ultrasonic welding can cover the whole magnet, which is great for medical or outdoor use.

ZOYN is good at making custom solutions. They work with customers to design and make magnets that fit just right, from shape and size to how they are magnetized and put together.

 

These ways to customize help makers build products that are different from others. That is why injection-molded magnets are a top pick for new designs.

 

Performance Benefits

 

Corrosion Resistance

Injection-molded magnetic components do not rust easily. The polymer binder makes a shield around each magnetic particle. This shield keeps water and harmful stuff away from the metal inside. Special coatings, like phosphatizing or silane, make the bond between the powder and polymer stronger. These steps help magnets last longer, even in tough places.

• The polymer binder keeps magnetic particles apart.

• Surface coatings help magnets stay strong in bad weather.

• The smooth surface helps stop chips and cracks.

 

Tests show these magnets lose less than 5% of their strength after hot water, quick temperature changes, or steam. This makes them great for cars, medical tools, and outdoor gear.

 

Dimensional Accuracy

Injection molding makes parts very exact. Most parts are made with tolerances close to ±0.005 mm. This happens because of special CNC molds and careful process checks. The process also makes smooth surfaces and even magnetic strength.

 

Feature Size Range (mm)	Typical Dimensional Tolerance (mm)	Notes
< 3	±0.03	Small features
3 to 6	±0.05	Medium small features
6 to 15	±0.08	Medium features
15 to 30	±0.15	Larger features
30 to 60	±0.25	Largest features

 

Sintered magnets need extra cutting and grinding. This lowers accuracy and wastes material. Injection-molded magnets are made in one step. This keeps sizes right and cuts down on waste.

 

Temperature Stability

Injection-molded magnets work well in many temperatures. The binder and powder picked set the highest safe temperature. For example, Nylon 6 magnets can take up to 150°C. PPS magnets can go up to 180°C. SmCo powders are very stable in high heat.

 

Binder / Magnetic Material	Maximum Operating Temperature	Notes
Nylon 6 (PA6)	140-150°C	Common binder for injection molding
Nylon 12 (PA12)	120-150°C	Not recommended above 150°C
PPS	Up to 180°C	High temperature binder
Ferrite + Nylon 6	Up to 150°C	Good for automotive parts
Ferrite + PPS	Up to 180°C	For high-temperature environments
NdFeB (high energy grade)	Up to 120°C	Irreversible loss above 120°C

 

The right binder and powder mix keeps magnets stable, even when it gets hot.

 

Low Eddy Current Losses

Injection-molded magnets use tiny powders mixed with plastic binders. This setup breaks up the paths that eddy currents use. Coatings on each particle keep eddy currents small. Because of this, these magnets do not waste much energy as heat. This makes them good for motors and sensors.

• Small powder and coatings stop big eddy current loops.

• The plastic binder blocks eddy currents, making magnets work better.

• Low eddy current loss helps devices stay cool and last longer.

This special structure helps injection-molded magnets work well in fast and high-frequency uses.

 

Cost and Efficiency

Mass Production

Injection-molded magnetic components are great for making lots of parts. Companies spend money on molds and machines at first, but they save money later. The process is fast and makes many parts that are all the same. These parts are made with high accuracy. Makers can create tricky shapes and close fits that are hard with other ways. This is why injection molding is good for making millions of parts, like in cars, brakes, and electronics.

 

Injection molding is special because it makes complex magnetic parts quickly and at a low cost.

 

Reduced Waste

Injection molding makes less waste than old ways of making magnets. It uses just the right amount of material for each part, so there is not much left over. Companies often use leftover bits again, which helps the environment.

• Magnets help sort waste better, so less goes to landfills.

• Better sorting helps with recycling and being green.

• Using leftovers again in magnet making is good for the planet.

• Less waste means we help the earth more.

• Using magnets in waste work helps protect nature.

Using materials wisely saves money and helps companies be more eco-friendly.

 

Assembly Integration

With injection-molded magnets, building things is easier. Makers can put magnets right into plastic parts while molding. This means fewer steps and faster making of products.

• Insert molding sticks magnets and plastic together, making them strong.

• Fewer screws or glue are needed, so there are fewer parts and lower costs.

• Robots help place magnets, making things more exact and saving work.

• Putting many parts into one molded piece gives more design choices and better results.

For example, in car sensors and vacuums, putting magnets in during molding means no extra steps later. This makes products work better and cost less to make. Getting all parts from one place also makes it easier to keep track and check quality, so everything runs smoother.

 

Comparison with Traditional Methods

 

Sintered Magnets

Sintered magnets have been used in motors and electronics for a long time. They are made by pressing and heating magnetic powders until they stick together. This makes them strong, but also easy to break or chip. Injection-molded magnets are made differently. They mix magnetic powder with plastic and shape it in molds. This makes them tougher and less likely to crack.

 

Aspect	Injection-Molded Ferrite Magnets	Sintered Ferrite Magnets
Production Process	Ferrite powder mixed with thermoplastic binders and additives, injection molding technology	Produced like ceramics by sintering ferrite powder
Shape Complexity	Can produce complex shapes	Limited to simpler shapes (round, ring, tile, cylindrical)
Dimensional Accuracy	Higher accuracy (±0.08 mm)	Lower accuracy (±0.1 mm)
Mechanical Durability	Better drop and wear resistance due to nylon component	More brittle, less resistant to drop and abrasion
Magnetic Properties	Lower magnetic strength	Higher magnetic strength
Temperature Resistance	Maximum operating temperature around 100-150°C	High temperature resistance up to 250°C or above 400°C
Typical Applications	Used where complex shapes, precision, and mechanical durability are needed (motor components, Hall sensors, electronic appliances, precision instruments)	Preferred where higher magnetic strength and temperature resistance are critical

 

Injection-molded magnets can be made into many shapes and sizes. Their plastic part helps them survive drops and scratches. Sintered magnets are stronger but break more easily. They also cannot be made into as many shapes as injection-molded magnets.

 

Injection-molded magnets let designers make tough parts in many shapes. This is good for products that need both strength and special designs.

 

Compression Bonded Magnets

Compression bonded magnets are made by pressing magnetic powder and binder together. Then, they are cured to make them solid. This way makes stronger magnets, but shapes are limited. It also takes longer to make them. Injection-molded magnets use melted plastic and magnetic powder. This mix is put into molds to make parts. This method is faster and can make more shapes.

When someone mentions neodymium magnets, most people think of those shiny silver discs used in gadgets or magnetic tools. But there's a lesser-known type—strong material bonded neodymium—that offers surprising flexibility. And if you're in product design, this might just be the quiet hero you've been overlooking.

 

Not All Magnets Are Rigid and Sharp-Edged

Unlike traditional sintered neodymium magnets, which are strong but brittle, bonded versions are made by mixing magnetic powder with a binding agent like resin. That might sound like a downgrade, but it actually unlocks a whole new world of customization.

 

Here’s the thing: bonded magnets can be molded. That means you’re not stuck with basic cylinders or rectangles—you can ask for gear shapes, curved strips, even hollow cylinders. And because the material is more forgiving, there’s less risk of cracking during machining or assembly.

 

Designers Love the Shape Freedom

In traditional magnet setups, engineers often have to design around the magnet. With bonded magnets, it’s kind of the opposite. The magnet can be made to fit your product’s form—whatever that looks like.

 

For instance, if you’re designing a compact motor that fits into a strangely-shaped housing (think electric toothbrush, drone rotor, or compact cooling fan), you can mold a ring magnet with radial magnetization and complex inner contours. That kind of precision just isn’t feasible with hard sintered magnets.

 

Magnetization That Matches the Application

Now let’s talk magnetization. Most people don’t realize that magnets aren’t just north and south. In bonded neodymium magnets, you can request custom magnetization patterns—multi-pole, radial, axial, even combinations.

 

Imagine a motor that needs smooth torque or a sensor that relies on precise pulse signals. A magnetized ring with 8 or 16 poles evenly spaced around it? That’s entirely doable. You get to optimize the magnetic field to suit your needs, not the other way around.

 

Lightweight and Corrosion-Resistant

Another underappreciated trait: bonded magnets are usually lighter. Because they're partially plastic, they’re not as dense as solid sintered versions. This is a plus in portable electronics, drones, or anything battery-powered.

 

Also, since the magnetic particles are embedded in resin or polymer, they’re less prone to corrosion, even in moist or semi-aggressive environments. No need for heavy plating or worrying about rust eating away at performance.

 

Integration and Overmolding Make Assembly Easier

Ever dealt with tiny magnets that have to be glued or slotted into plastic housings? It’s tedious—and not always reliable. With bonded magnets, you can actually overmold them with plastic components or combine them directly with structural parts. That saves time, reduces part count, and improves overall durability.

 

For example, a company designing a fitness tracker could mold the magnet into the clasp or charging dock, making the product feel seamless and intentional, not pieced together.

 

Small Batch? No Problem.

Tooling costs for injection-molded magnets are lower than for sintered ones. And if you’re doing a short production run—maybe you’re launching a prototype or niche product—you don’t want to invest in expensive tooling for sintered shapes.

 

Bonded magnets let you start small, iterate fast, and scale only when needed.

 

So yes, bonded neodymium ring magnets aren’t quite as strong as their sintered cousins. But in design, strength isn’t everything. Flexibility, shape complexity, magnetic orientation, corrosion resistance, and ease of integration often matter just as much—if not more. 

 

When your product needs to stand out—or fit somewhere unusual—custom bonded neodymium magnet give you the freedom to design the way you want, not the way the magnet forces you to. Contact us to get more products informaition. Our Whatsapp number: +8615167129264 / +8615888988057

Ratchet tie-down straps are essential tools for securing cargo during transportation. Properly threading a ratchet tie-down is crucial to ensure the safety and security of your load. In this blog post, we will provide a comprehensive step-by-step guide on how to correctly thread a ratchet tie-down for effective load securing.

 

Before threading the ratchet tie-down, examine the strap for any signs of damage or wear. Ensure that the ratchet mechanism is in good working condition and free from debris that could hinder its operation.

 

Open the ratchet handle to release the strap completely. Make sure the release lever is in the locked position before proceeding.

Insert the loose end of the strap through the spool located on the ratchet mechanism. Pull the strap through until there is enough slack to wrap around the cargo and secure it.

Wrap the strap around the cargo you wish to secure. Make sure the strap lies flat without twists or knots that could weaken the securing strength.

Once the strap is looped around the cargo, feed the loose end back through the ratchet mechanism in the opposite direction. Pull the strap taut to remove any slack, ensuring a firm and secure grip on the load.

Close the ratchet handle to engage the tightening mechanism. Begin cranking the ratchet handle back and forth to tighten the strap around the cargo. Make sure the strap remains flat and properly aligned as you tighten it.

Continue cranking the ratchet handle until the strap is securely tensioned around the cargo. Once you reach the desired tension, lock the ratchet handle in place to prevent the strap from loosening during transport.

After tightening the ratchet strap, secure any excess length by winding it around the ratchet handle or using Velcro straps to prevent it from flapping in the wind.

Verify that the strap is securely fastened and shows no signs of slack or loosening. Give the secured load a gentle tug to confirm that the ratchet tie-down is holding the cargo firmly in place.

 

By following these steps, you can effectively thread a ratchet tie-down and securely fasten your cargo for safe transportation. Remember to regularly inspect your ratchet straps for wear and tear, and replace them when necessary to maintain optimal load securing capabilities.
