 Processing 
 Drying: 

 PA6 can easily absorb moisture, drying prior to processing in particular to note that if the material is packed in waterproof material supply, the container should be kept tightly closed. If the humidity is greater than 0.2%, it is recommended that dry in the hot air of 80 ° C above 16 hours. If the material is exposed to air for more than eight hours, it is recommended that the temperature is 105 ° C, more than 8 hours of vacuum drying. 

 Melting temperature: 

 230-280 ℃, 250-280 ℃ enhanced varieties. 

 Mold temperature: 

 80-90 ℃. The mold temperature significantly affect the cleanliness, cleanliness affects the plastic parts of the mechanical properties. Degree of crystallinity is very important for the structural components, and therefore recommended that the mold temperature is 80-90 ℃. For thin-walled, processes long plastic parts also recommended that the application of a higher mold temperature. Increasing the mold temperature can improve the plastic parts of the strength and stiffness, but reduces the toughness. If the wall thickness greater than 3mm, it is recommended that the low temperature of 20-40 ° C mold. Glass fiber reinforced materials, mold temperature should be greater than 80 ℃. 

 Injection pressure: 

 Generally between 750-1250bar (depending on material and product design) 

 Injection speed: 

 High-speed (reinforcing material is slightly lower) flow channel and the gate: For PA6 the solidification time is very short, so the gate location is very important. The gate aperture of not less than 0.5 * T (here T is the thickness of plastic parts). If you use the hot runner, gate size should be smaller than the use of conventional flow, because of the hot runner can help to prevent the material from premature solidification. If sneaked into the gate, the gate of the minimum diameter should be 0.75mm. 

 Chemical and physical properties 
 PA6 chemical physical characteristics are very similar and PA66, however, its low melting point, and the process temperature range is very wide. Its impact resistance and solvent resistance than PA66 is better, but also more hygroscopic. Because many of the qualities characteristic of the plastic parts must receive the hygroscopicity of the PA6 design products should give full consideration to this point. In order to improve the mechanical properties of PA6, often adding a variety of modifiers. The glass fiber is the most common additives, sometimes in order to improve the impact resistance by adding a synthetic rubber such as EPDM and SBR. For products with no additives, PA6 contraction of 1% to 1.5%. Glass fiber additives can be reduced to 0.3% shrinkage (but also slightly higher and the flow perpendicular to the direction of some). Shrinkage of the molding assembly is mainly affected by a material degree of crystallinity and hygroscopicity effects. The actual shrinkage and plastic parts design, wall thickness and other process parameters as a function of
