（一）采用聚丙烯pp原料

(1) using polypropylene PP raw materials

PP是由丙烯聚合而制得的一种热塑性树脂，是一种半结晶性材料，它比PE要更坚硬并且有更高的熔点。聚丙烯（pp）具有很好的可塑性，可溶性和韧性。

PP is a thermoplastic resin made by the polymerization of propylene. It is a semi crystalline material, which is harder than PE and has a higher melting point. Polypropylene (PP) has good plasticity, solubility and toughness.

（二）采用ABS树脂

(two) using ABS resin

ABS树脂是微黄色固体，有一定的韧性，它抗酸、碱、盐的腐蚀能力比较强，也可在一定程度上耐受有机溶剂溶解。ABS树脂很好的成型性，加工出的产品表面光洁，易于染色和电镀。ABS树脂的优点是抗冲性、隔音性、耐划痕性、耐热性好。

ABS resin is a yellowish solid, has a certain toughness, its acid resistance, alkali, salt corrosion ability is relatively strong, but also to some extent withstand organic solvent dissolution. ABS resin has good formability. The finished products are smooth and easy to dye and electroplate. The advantage of ABS resin is its good resistance to noise, noise, scratch and heat resistance.

当然不管是采用pp原料，还是ABS树脂原料，其成型工艺都是大同小异的，即颗粒高温下化成液态，是液体流入特定好的铁模具中，利用液态水循环使其冷却，塑料就根据模具的规格而塑型，当然模具是根据每个客户的图纸特定的，从而产生电缆盖板模具的各种尺寸。

Of course, whether using PP or ABS resin raw materials, raw materials, the molding process is similar, namely the particle formation under high temperature liquid is liquid into the iron mold specific good, the use of liquid water circulation cooling, according to the specifications of the plastic mold plastic mold is of course, according to each customer's specific drawings. Various sizes, resulting in cable trench cover mold.
