[Chemical and Physical Properties of Nylon]
The chemical and physical properties of nylon are very similar to nylon, however, its melting point is lower and the process temperature range is wide. Its impact resistance and dissolution resistance are better than nylon plastic, but it is also more hygroscopic. Because many quality characteristics of plastic parts are affected by hygroscopicity, this should be fully taken into consideration when designing products using nylon.
In order to improve the mechanical properties of nylon, various modifiers are often added. Glass is the most common additive, and sometimes synthetic rubber, such as and BR, is added to improve impact resistance. For products without additives, the shrinkage rate of nylon plastic raw materials is between % and %. Adding glass fiber additives can reduce the shrinkage to % (but it is slightly higher in the direction perpendicular to the process). The shrinkage rate of molded assembly is mainly affected by the crystallinity and hygroscopicity of the material. The actual shrinkage rate is also a function of the designed wall thickness of the plastic part and other process parameters.
Drying treatment of nylon injection molding Since nylon easily absorbs moisture, special attention should be paid to drying before processing. If the material is supplied in waterproof packaging, the container should be kept closed. If the humidity is greater than %, it is recommended to dry it in the above hot air for an hour.
If the material has been exposed to air for more than an hour, it is recommended to perform vacuum drying for more than an hour. Nylon injection molding process parameters melt temperature: ℃, for reinforced varieties is ~.
【Injection Molding Parameters】
Barrel constant temperature: ℃
Mold temperature: ℃. Mold temperature significantly affects crystallinity, which in turn affects the mechanical properties of plastic parts. Crystallinity is important for structural parts, so the recommended mold temperature is ~. For thin-walled plastic parts with long processes, it is also recommended to use higher mold temperatures. Increasing the mold temperature can increase the strength and stiffness of plastic parts, but reduces the toughness. If the wall thickness is greater than 100%, it is recommended to use a low-temperature mold of ~. For glass reinforced materials the mold temperature should be greater than.
Injection pressure: (br), if you are processing thin-surface long flow channel products (such as wire ties), you need to reach (br).
Holding pressure: % of injection pressure. Since the material solidifies relatively quickly, a short holding time is sufficient. Reducing the holding pressure can reduce the internal stress of the product.
Back pressure: (br), needs to be adjusted accurately, because too high a back pressure will cause uneven plasticization.
Injection speed: It is recommended to use a relatively fast injection speed so that the mold has good ventilation, otherwise coking will occur on the product. High speed (slightly lower for reinforced materials).
Screw speed: The screw speed is high and the linear speed is / However, it is better to set the screw speed lower, as long as the plasticizing process can be completed before the end of the cooling time, a lower screw torque is required.
Measuring stroke:
Remaining material amount: It depends on the metering stroke and screw diameter.
Pre-drying: Drying at ℃ temperature. In addition to feeding nylon directly from the charging container, which is water-absorbent, it should be stored in a moisture-proof container and a closed hopper. Water content exceeding % will cause molding changes.
Recovery rate: % recycled material can be added.
Shrinkage rate: %% or adding % glass fiber, the shrinkage rate is %%. If the provided temperature exceeds ℃, the product should be gradually cooled. Gradual cooling can reduce the shrinkage after molding. That is to say, the product shows better dimensional stability and small internal stress. It is recommended to use steam method. Nylon plastic products can check the stress by welding liquid agent.
Gate system: point type, latent type, chip type and straight gate can all be used. It is recommended to use blind holes and gate nests to segment the cold material points. Hot runners can be used. Since the molten material can be processed in a narrow temperature range, hot runner Closed loop temperature control should be provided. Since nylon has a very short setting time, the location of the gate is very important. The gate hole diameter should not be smaller than * (here is the thickness of the plastic part). If using a hot runner, the gate size should be smaller than if using a conventional runner because the hot runner can help prevent premature solidification of the material. If a submersible gate is used, the minimum gate diameter should be.
Barrel equipment: standard screw, special geometric size and high plasticizing capacity check ring, straight-through nozzle. For reinforced materials with glass fiber, a highly wear-resistant bimetallic barrel is required
Machine Downtime period: There is no need to use other materials to clean the molten material remaining in the barrel for up to a period of time, after which thermal degradation is prone to occur. Typical applications of nylon are widely used in structural components due to its good mechanical strength and stiffness. Due to its good wear resistance properties, it is also used in the manufacture of bearings. High-performance reinforced nylon composite materials are used in automobiles to manufacture engine peripheral parts, such as intake manifold hood covers.
Drying treatment:
Since it is easy to absorb moisture, special attention should be paid to drying before processing. If the material is supplied in waterproof material packaging, the container should be kept airtight. If the humidity is greater than %, it is recommended to dry it in hot air above ℃ for an hour. If the material has been exposed to air for more than 1 hour, it is recommended to perform vacuum drying at a temperature of ℃ for more than 1 hour.
Melting temperature:
℃, for reinforced varieties it is ℃.
Mold temperature:
℃, the mold temperature significantly affects the crystallinity, and the crystallinity affects the mechanical properties of the plastic parts. Crystallinity is important for structural parts, so it is recommended that the mold temperature be ℃. It is also recommended to use higher mold temperatures for thin-walled plastic parts with longer processes.
Increasing the mold temperature can increase the strength and stiffness of the plastic part, but reduces the toughness. If the wall thickness is greater than 1°C, it is recommended to use a low temperature
mold at ℃. For glass fiber reinforced materials, the mold temperature should be greater than ℃.
Injection pressure:
Generally between br (depends on material and product design)
Injection speed:
High speed (slightly lower for reinforced materials)
Runner And gate:
For the solidification time is very short, so the location of the gate is very important. The gate hole diameter should not be smaller than * (here is the thickness of the plastic part).
If using a hot runner, the gate size should be smaller than if using a conventional runner, because the hot runner can help prevent premature solidification of the material. If a submersible gate is used, the minimum gate diameter should be.
