In Large thick sheet thermoforming In the processing and manufacturing industry, there are usually four types of thermoforming molds on the market: plaster molds, electroplated copper molds, and aluminum molds.

1. Plaster mold: The production of a plaster mold involves carving plaster in a semi-wet state and then drying it to form the mold. The cost of preparing plaster molds is low. Due to its low hardness and strong plasticity, it is easy to modify. However, there is a clear problem, that is, the plaster mold is not accurate enough, the surface is not smooth, it is fragile, and not durable, so it is often used as a model for electroplated copper molds or certain models.

2. Electroplated copper mold: The production of electroplated copper molds is relatively simple. It only involves electroplating a copper shell on the sample made from the plaster mold, which is the electroplated copper mold. Because its production is based on plaster molds, the production cost of plaster molds is relatively high, but it is cheaper than aluminum molds. However, due to its smooth, durable surface and low cost, electroplated copper molds are the most commonly used type of thermoforming mold.

3. Aluminum mold: We often say that the production of aluminum molds actually involves using aluminum ingots processed by machinery (including lathes, milling machines, CNC, etc.). Compared with other molds, aluminum molds have higher precision, a smooth surface, and durability. Although aluminum molds are good, they are expensive, and aluminum molds are usually used in plastic products with high-precision requirements that copper molds cannot achieve.

Large thick sheet thermoforming The choice of mold is closely related to the quantity of products processed by thermoforming. The choice of mold for thermoforming production depends on various factors, including the product. Of course, from the above three molds, it is said that products thermoformed using aluminum molds are better in terms of precision, but the price is also relatively expensive.
