Good impact resistance; High transparency; Wide use temperature range: -40 to 160; Good precision forming performance, stable molding size; Ultra-high self-extinguishing performance; Super weather resistance; Good electrical insulation. Jiangsu, Zhejiang and Shanghai first-class agent PC Mitsubishi Engineering HL-3003 original factory original package /PC injection molding processing conditions (1) Plastic treatment :PC water absorption rate is larger, must be preheated and dry before processing, pure PC drying 120℃, modified PC generally with 110℃ temperature drying for 4 hours Up. The drying time should not exceed 10 hours. Generally, the air extrusion method can be used to determine whether the drying is enough. The proportion of recycled material can reach 20%. In some cases, 100% of the recycled material may be used, depending on the quality requirements of the product. The recycled material should not be mixed with different masterbatches at the same time, otherwise it will seriously damage the nature of the finished product. (2) The selection of injection molding machine: the current PC products due to cost and other reasons, more modified materials, especially electrical products, but also to increase the fire performance, in the flame retardant PC and other plastic alloy products molding, the requirements of the injection molding machine plasticizing system is mixed well, corrosion resistance, conventional plasticizing screw is difficult to do, in the purchase, must be explained in advance. (3) Mold and gate design: the common mold temperature is 80~100 ° C, plus glass fiber is 100~130 ° C, small products can be used pin gate, gate depth should be 70% of the thickest part, other gates have rings and rectangles. The larger the gate, the better, in order to reduce the defects caused by excessive shear of plastic. The depth of the exhaust hole should be less than 0.03~0.06mm, and the flow path should be as short and round as possible. The demoulding inclination is generally about 30'~1°.
The degree is 270~320℃, and some working temperatures are high or low modified or low molecular weight PC is 230-270℃.
(5) Injection speed: More commonly used faster injection speed molding, such as electrical switch parts. Common for slow → rapid prototyping.
(6) Retention time: If the residence time is too long at high temperature, the material will degrade, put CO2 and become yellow. If the residence time is too long at high temperature, the material will degrade, put CO2, and become yellow.
(7) Precautions: Some modified PC, due to too many times of recovery (molecular weight reduction) or uneven mixing of various components, easy to produce dark brown liquid bubbles.
