PA6 mold temperature significantly affects the crystallinity, while crystallinity affects the mechanical properties of the plastic parts. The crystallinity is very important for structural components, so it is recommended that the die temperature is 80-90 degrees centigrade. Higher die temperatures are also recommended for thin-walled, longer flow plastic parts. Increasing the mold temperature can improve the strength and stiffness of the plastic parts, but reduce the toughness. If the wall thickness is greater than 3mm, a 20-40 degree low temperature mold is recommended. For glass fiber reinforced materials, the mold temperature shall be greater than 80 degrees centigrade. Injection pressure: generally between 750-1250bar (depends on material and product design) injection speed high (the reinforcing material to be reduced slightly) runners and gates for the solidification time of PA6 is very short, the gate location is important. The gate hole diameter should not be less than 0.5*T (T here is the thickness of plastic parts). If hot runner is used, the gate size should be smaller than the conventional runner because the hot runner can help prevent premature solidification of the material. If the submerged gate is used, the Zui diameter of the gate shall be 0.75mm. Fold this section for other information

Conductive nylon 66: with good wear resistance, heat resistance, oil resistance and chemical resistance, but also greatly reduce the water absorption and shrinkage of raw materials, with excellent dimensional stability and excellent mechanical strength. Requirements for electrostatic dissipation and electrostatic discharge (ESD) protection. These specially modified materials are specially formulated and suitable for surface resistance ranges from 100 to 1012 ohms per square meter (ohms), which can be used for injection molding and extrusion molding. There are many advantages over metal and coating: the parts are lighter in weight, easier to handle, and lower in transportation cost. They are easy to assemble, less expensive to manufacture, and less likely to be dented, cut and scratched. For identification or aesthetic purposes, some materials can be pre dyed to avoid free and expensive two coloring processes. ABS QU-0191S↖

The performance of LDPE polyethylene depends on the way it is polymerized. High density polyethylene (HDPE) is obtained by Ziegler-Natta polymerization at moderate pressure (15-30 ATM) under organic catalyst conditions. Under these conditions, the polymerized polyethylene molecules are linear, and the molecular chains are very long and the molecular weight is up to hundreds of thousands. If it is under high pressure (100-300MPa), high temperature (190 - 210 degrees C), radical polymerization under peroxide catalysis, the low density polyethylene (LDPE) is produced, and it is branched.

Polymerization pressure size: high pressure, medium pressure, low pressure;
Polymerization methods: slurry method, solution method, gas phase method;
Product density: high density, medium density, low density, linear low density;
Molecular weight of products: low molecular weight, common molecular weight, ultra high molecular weight. Ethylene copolymer: ethylene propylene copolymer (plastic), EVA, ethylene butene copolymer, ethylene and other olefins (such as octene POE, cyclic olefin copolymer), ethylene unsaturated ester copolymer (EAA, EMAA, EEA, EMA, EMMA, EMAH)
A linear polyethylene with a molecular weight of 3000000-6000000 is called ultra high molecular weight polyethylene (UHMWPE). Ultra high molecular weight polyethylene (PE) is very strong and can be used as a bulletproof vest.
PP common acid and alkali soluble You Ji it almost does not work, can be used for utensils. PP is a semi crystalline material. It is harder than PE and has a higher melting point. Since the PP temperature of homopolymer is more than 0 degrees Celsius, it is very brittle, so many commercial PP materials are copolymers with 1 to 4% ethylene random copolymer or higher ratio ethylene content. The PP material of polymers has lower thermal distortion temperature (100 DEG C), low transparency, low gloss and low rigidity, but has stronger impact strength. The strength of PP increases with the increase of ethylene content. The softening temperature of VEKA at PP is 150 DEG C. Due to its high crystallinity, the surface stiffness and scratch resistance of the material are very good.
