in thick blister packaging manufacturer In the thick blister packaging manufacturers and manufacturing industries, there are usually four common blister molds on the market: they are plaster molds, electroplated copper molds, and aluminum molds.
Plaster molds: The production of so-called plaster molds involves carving and shaping the plaster in a semi-wet state, then drying it to form a mold. Plaster molds have low production costs. Due to their low hardness and strong plasticity, they are easy to modify. However, there is a very obvious problem, that is, the plaster mold is not accurate enough, the surface is not smooth, and it is fragile and not durable. Therefore, it is often used for camouflage, as a mold for electroplated copper molds, or some plastic shell blister packaging with low requirements for small-batch production.

Electroplated copper molds: The production of electroplated copper molds is relatively simple. Based on the samples made from plaster molds, it is only a layer of copper shell, which is the electroplated copper mold. Since its production is based on plaster molds, the production cost of electroplated copper molds is higher than that of plaster molds, but much cheaper than aluminum molds. Due to its smooth, durable surface and low cost advantages, electroplated copper molds are the most commonly used Medical device blister packaging shell 。

Aluminum molds: We often say that the production of aluminum molds is actually processed using aluminum ingots through machinery (including lathes, milling machines, CNC, etc.). Compared with other molds, aluminum molds have higher precision and have smooth surfaces and durable characteristics. Although aluminum molds are good, they are very expensive. Aluminum molds are usually used for blister products that require higher precision, which copper molds cannot achieve.
Plastic shell blister packaging The selection is closely related to the product requirements and quantity of plastic shell blister packaging. Which mold is most suitable for blister processing and production. Of course, take a look at the above three molds. It is said that products made with aluminum molds will have better quality and precision than others.
