In general, plastic packaging molds are made of gypsum, but wood carving and metal carving products are also used as molds. After the gypsum mold is made, let it naturally dry or dry completely.
Put the softened plastic board and wooden cabinet into the vacuum chamber, and start the suction switch to suck the air in the vacuum chamber. After the plastic sheet is cooled, the same concave packaging or processing mold as the mold can be obtained.
Blister packaging and finishing; Trimming and finishing the produced products is the finished product, which can be sold after packaging.
Extended data
There are generally three kinds of plastic packaging molds: gypsum mold, copper electroplating mold and aluminum mold:
1. Gypsum mold: sculpt with gypsum in semi-wet state, and then dry the mold. Gypsum molds are low in cost and easy to modify, but the accuracy is not high enough, and the surface is not smooth and fragile, so they are often used to make fake copper molds or some plastic suction molds produced in small batches.
2. aluminum mold: aluminum ingot is machined (lathe, milling machine, CNC, etc.). ). Aluminum molds have high precision, smooth surface and durability, but the price is very expensive. Aluminum mold is generally used for plastic products with high precision, which copper mold can't reach.
3. Electroplating copper mold: After the sample is made of gypsum mold, a layer of copper shell is electroplated, which is higher than gypsum mold, but much cheaper than aluminum mold. Copper electroplating die is the most commonly used plastic suction die because of its smooth and durable surface and low cost.
