Blister is a kind of plastic processing technology. After heating and softening the flat plastic hard sheet, it is adsorbed on the surface of the mold by vacuum and formed after cooling. It is widely used in plastic packaging, lighting, advertising, decoration and other industries.


Wuxi Dexing Plastic Technology Co., Ltd. is a scientific and technological innovation enterprise established with the concept of diversified resources integrating plastic technology. Taking the blister process as the core and a variety of other plastic processes as supplements, we are committed to providing overall product solutions and product packaging supply chain management services.

Next, the editor of Dexing shares what are the commonly used molds for blister?

1. Substitute wood model. The material is substitute wood, the material cost is relatively high, CNC processing is required, the manufacturing cycle is short, usually a few hours, and it is easy to polish and perforate. The data is also relatively crisp, suitable for proofing under the scene of 3D image files, not for production.

2. Plaster mold. The data is gypsum powder, which is simple to manufacture and modify. Usually, a single mold only takes 1 to 3 days. Because of its brittleness and difficulty in heat dissipation, gypsum molds are usually used to craft samples when there are samples, not for production.

3. Bakelite mold. The data is Bakelite, about 20 yuan per kilogram, and it needs CNC processing. The manufacturing cycle is slightly longer than that of Yokogi, and it is more difficult to grind and punch than Yokogi.

4. Copper mold. The primary requirement of copper mold is to make a model with plaster mold, then take the model to plate copper, and then fill the interior with plaster. The surface finish of the copper mold is good, and the strength can reach the usual production requirements. It is one of the widely used blister molds.
