About plastic mould

plastic mold generally have cast mould, electroplating copper and aluminum mold three
plaster mold: use of gypsum in semi wet hand carved molding and drying simple mold, plaster mold low cost artificial high, easy to modify, but the plaster mold precision is not high enough, smooth surface and fragile not durable, so it is often used in proofing and electroplating copper model species.
aluminum mold: aluminum ingot by mechanical (lathe, milling machine, cnc processing and etc.). aluminum mold, high precision, smooth surface and durable, but the price is very expensive, aluminum mold generally used in precision higher copper is not up to the very large amount or plastic products.
copper electroplating: with plaster mold for the finished product, electroplating a layer of copper is copper electroplating, although not very precise, but than aluminum mold prices much cheaper, due to its surface smooth, durable and low cost advantages, copper electroplating is the most common kind of plastic mould.

About plastic materials

Plastic products of raw materials only plastic sheets, film thickness is generally not more than 10MM, commonly used in the sheet are: PPE, etc..
The most commonly used plastic materials, soft, strong toughness, good plasticity, can be made transparent and a variety of colors!

PP: material is particularly soft, good toughness, environmental non-toxic, high temperature resistant to 160 centgrade degree, often be made catering appliance or other high temperature resistant products packaging; but the plasticity, processing difficulty is big, the surface gloss difference and processing color becomes shallow.
