Blister packaging molds generally have three types: plaster mold, electroplated copper mold and aluminum mold.
Plaster mold: Engraved with gypsum in a semi-wet state, and then dried into a mold. The plaster mold has low cost and is easy to modify, but the plaster mold is not high enough, the surface is not smooth and fragile and not durable, so it is commonly used to fight 佯, do molds for electroplated copper molds or some plastic molds that require less high-volume production.
Aluminum mold: It is machined by machine (lathe, milling machine, CNC, etc.) with aluminum ingot. The aluminum mold has high precision, smooth surface and durability, but the price is very expensive. The aluminum mold is generally used in plastic products that cannot meet the high precision copper mold.
Electroplated copper mold: After the sample is made of gypsum mold, electroplating a copper shell is an electroplated copper mold. The cost is higher than that of the plaster mold, but it is much cheaper than the aluminum mold. Because of its smooth and durable surface and low cost, electroplating Copper mold is the most commonly used type of plastic mold.
