PA6 plastic raw material process conditions melt temperature? 240-250 °C barrel constant temperature? 220 °C PA6 mold temperature? 60-100 °C drying treatment? Because PA6 is easy to absorb moisture? Therefore, special attention should be paid to the drying before processing? If the material is used If the waterproof material is supplied in a package, the container should be kept closed. If the humidity is greater than 0.2%, it is recommended to dry in hot air above 80 °C for 16 hours. If the material has been exposed to air for more than 8 hours, it is recommended to perform vacuum drying at a temperature of 105 ° C for more than 8 hours. Melting temperature? 230-280 ° C? For enhanced varieties 250-280 ° C. Mold temperature? 80-90 ° C. The mold temperature significantly affects the crystallinity, which in turn affects the mechanical properties of the part. Crystallinity is important for structural components? It is therefore recommended that the mold temperature be 80-90 °C. It is also recommended to apply a higher mold temperature for thin-walled, longer-flowing plastic parts. Increasing the mold temperature increases the strength and stiffness of the part, but reduces the toughness. If the wall thickness is greater than 3mm, a low temperature mold of 20-40 °C is recommended. For glass fiber reinforced materials, the mold temperature should be greater than 80 °C. Injection pressure? Generally between 750-1250bar? Depends on material and product design? Injection speed? High speed? Reduces the reinforcement material slightly? Flow path and gate? The solidification time for PA6 is very short? Therefore, the position of the gate is very important. The gate aperture should not be less than 0.5*T? Where T is the thickness of the plastic part?. If a hot runner is used, the gate size should be smaller than with a conventional runner because the hot runner can help prevent premature solidification of the material. If a submerged gate is used, the minimum diameter of the gate should be 0.75 mm. Injection pressure? 100-160MPa? 1000-1600bar?? If it is processing thin surface long runner products, such as wire tie, it needs to reach 180MPa? 180bar?. Holding pressure? 50% of injection pressure? Because material condensing is relatively fast? Short holding time is sufficient. Reducing the holding pressure reduces the stress inside the product. Back pressure? 2-8MPa? 20-80bar?? Need to be accurately adjusted? Because the back pressure is too high, it will cause uneven plasticization.



The chemical and physical properties of PA6 are similar to those of PA66. However, it has a low melting point and a wide process temperature range.
It has better impact resistance and solubility resistance than PA66, but it is also more hygroscopic. Because of the many quality characteristics of plastic parts
It is subject to hygroscopicity, so take this into account when designing your product with PA6. To improve
The mechanical properties of PA6 are often added to a wide variety of modifiers. Glass is the most common additive, sometimes for
To improve impact resistance, synthetic rubbers such as EPDM and SBR are also added.
For products without additives, PA6 shrinks between 1% and 1.5%. Adding fiberglass additives can make
The shrinkage is reduced to 0.3% (but slightly higher in the direction perpendicular to the flow). The shrinkage rate of molding assembly is mainly
Affected by the crystallinity and hygroscopicity of the material.
