Blister packaging molds includes plaster molds, aluminum molds and electroplating molds generally.
Plaster mold: The semi-wet plaster is carved and molded, and then dried to make a mold. The cost of the plaster mold is low and easy to modify, but the accuracy of the plaster mold is not very high, the appearance is not smooth enough, and it is easy to break, so it is basically used Proofing, small batch production of blister molds.
Electroplating mold: On the basis of making a small sample of plaster, a shell is electroplated as an electroplated copper mold. The cost is higher than that of plaster mold, but its appearance is smoother and more durable, so it is also a common type of plastic mold.
Aluminum mold: It is made of aluminum ingot and processed by machinery. Aluminum molds have higher precision, more lubricated appearance and durable, but they are more expensive, and are generally used in blister products with higher precision.
