As a necessary auxiliary device for forming plastic products, plastic suction mold is indispensable for product production. By making moulds in advance, we can produce corresponding products according to the size and style of the dies. Among the many moulds we use, three are Blister aluminum mold, plaster mold and electroplating copper mould. So, what are the advantages and disadvantages of the three plastic suction moulds?

1. Plastic aluminum mould

This type of blister mold should be designed with computer and then processed by CNC CNC milling machine. The advantage is that the production cycle is moderate, and the mold processing time is short at the later stage. Its drilling can be done in CNC processing. The plastic products produced by this kind of mould have high dimensional accuracy and strong mould durability, and its disadvantage is high cost.

2. Plaster mold

Plaster mold is a widely used mold. Its advantage lies in its short production cycle and low production cost. Generally speaking, it takes only one to two days to make a whole (60 * 110cm) plastic suction mold. At the same time, it is inadequacies in the rough surface of the finished product, easy to break the mold in production, poor durability, and can not make the products with large depth, high complexity and thick sheet.

3. Electroplated copper mold

It uses a conductive agent sprayed on the surface of a good blister, and then a thick copper layer is placed in the electrolytic bath. The plating process takes 72 hours. Then the gypsum mold is added to the copper mold to increase the hardness, and polishing and air hole treatment are also needed. The advantage of the electroplating copper mould is that the surface of the mould is smooth, the cost is moderate and the durability is moderate. The disadvantage is that the mold production cycle is long, and can not complete the production of precision plastic products.
