If the humidity ismore than 0.2%, it is suggested that in the above 80 ℃ hot air drying 16hours. If the material has been exposed in the air more than eighthours, Suggestions for temperature is 105 ℃, 8 hours of vacuum drying.Melting temperature: 230-280 ℃, for enhanced varieties of 250-280 ℃.Mold temperature: 80-90 ℃. Mold temperature is significantly affect thedegree of crystallinity, and crystallinity and affects the mechanicalproperties of plastic parts. It's very important for structurecomponents crystallization degree, therefore suggested that moldtemperature is 80-90 ℃. For thin-wall, process long plastic parts alsosuggests applying higher mold temperature. Increase the mold temperaturecan improve the strength and stiffness of plastic parts, but it reducesthe toughness. If the wall thickness is greater than 3 mm, it isrecommended to use 20-40 ℃ low temperature mold. For glass fiberreinforced materials mold temperature should be greater than 80 ℃.Injection pressure: generally between 750-750 bar (depending on thematerial and product design) injection speed: fast (to enhance materialto slightly reduce) the runner and gate: for PA6 solidification time isvery short, so the location of the gate is very important. Gate diameternot less than 0.5 * T T is the thickness of the plastic parts (here). Ifyou use the hot runner and gate size should be smaller than usingconventional flow path, because of the hot runner can help preventpremature solidification material. If use into the gate, the minimumdiameter of gate shall be 0.75 mm. Chemical and physical properties aresimilar in chemical physics properties of PA6 and PA66, however, itsmelting point is lower, and the process temperature range is very wide.Its impact resistance and resistance to better solubility than PA66, butstrong hygroscopicity and more. Because many plastic parts qualitycharacteristics are affected by moisture absorption, so using PA6 designto give full consideration to this product. In order to improve themechanical properties of PA6, often to join all kinds of modifier. Glassfiber is one of the most common additives, sometimes in order to improvethe impact resistance also join the synthetic rubber, such as EPDM, SBRand so on. With no additive products, PA6 contraction between 1% and1.5%. Adding glass fiber additives can reduce shrinkage rate to 0.3%(but and process in the vertical direction but also a little higher).Assembly molding shrinkage is mainly affected by crystallinity andhygroscopic material. The actual shrinkage and plastic parts design,wall thickness and also other relations as a function of processparameters.
