PA6 mold temperature significantly affects the degree of crystallinity, and crystallinity affects the mechanical properties of the plastic parts. Crystallinity is important for structural components, so it is recommended that the mold temperature is 80-90. It is recommended to use higher mold temperatures for thin walled, longer flow processes. Increasing the mold temperature can improve the strength and stiffness of the parts, but the toughness is decreased. If the wall thickness is greater than 3mm, it is recommended to use the 20-40 low temperature mold. The glass fiber reinforced plastic mold temperature should be greater than 80 degrees C. 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 aperture shall not be less than 0.5*T (where T is the thickness of the plastic part). If the hot runner is used, the size of the gate should be smaller than that of the conventional runner, since the hot runner can help prevent premature solidification of the material. If the gate is submerged, the Zui diameter of the gate should be 0.75mm. Other information about this paragraph

Conductive nylon 66: good wear resistance, heat resistance, oil resistance and chemical resistance, but also greatly reduce the raw material water absorption and shrinkage, with excellent dimensional stability and excellent mechanical strength. It can meet the requirements of electrostatic dissipation and electrostatic discharge (ESD) protection. These special modified materials are specially formulated for surface resistance ranges from 100 to 1012 ohm / square (ohms), which can be used for injection molding and extrusion molding. There are many advantages over metals and coatings: lighter weight, easier handling and lower transport costs. The utility model has the advantages of simple assembly, low manufacturing cost, and no dent, cutting and scratching. In order to identify or aesthetic purposes, some materials can be pre dyed, avoid free and expensive two coloring process.
The properties of LDPE polyethylene depend on its polymerization. High density polyethylene (HDPE) was synthesized by Ziegler-Natta polymerization under the condition of medium pressure (15-30 ATM). Under this condition, the polyethylene molecules are linear, and the molecular chain is very long. If it is at high pressure (100-300MPa), high temperature (190 - 210 degrees C), peroxide polymerization under the conditions of free radical polymerization, the production of low density polyethylene (LDPE), it is a branched structure.
Polymerization pressure: 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: low molecular weight, 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)
Linear polyethylene with molecular weight of 3000000-6000000 is called ultra high molecular weight polyethylene (UHMWPE). Ultra high molecular weight polyethylene strength is very high, can be used to make bulletproof clothing.
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. Due to the fact that the PP temperature of the homopolymer type is more than 0 DEG C, it is very brittle, so many commercial PP materials are a kind of irregular copolymer or a higher proportion of ethylene content, which is added to the ethylene copolymer of 1 to 4%. The polymeric PP material has a low thermal distortion temperature (100 DEG C), low transparency, low gloss, and low rigidity, but has a stronger impact strength. The strength of PP increases with the increase of ethylene content. PP VEKA softening temperature of 150 degrees C. Due to its high crystallinity, the surface stiffness and scratch resistance of the material are very good.
