1. Plaster mold
Use gypsum to carve and shape in a semi-wet state, and then dry it to form a mold. The cost of the plaster mold is low, and the general price is about 300 yuan. If the customized quantity is small, the gypsum mold is generally used. Among these three molds, the price is the lowest. Yes, and cost-effective. And it is easy to modify, but the precision of the plaster mold is not high enough, the surface is not smooth, it is fragile and not durable, so it is often used for feinting, as a mold type for electroplating copper molds or some blister molds for low-volume production.
2. Electroplating copper mold
Generally, after the samples are made of plaster molds, a layer of copper shell is electroplated, which is an electroplated copper mold. The cost is higher than that of the plaster mold, but it is much cheaper than the aluminum mold. , can be reused, if you order a large amount, it is recommended to use electroplating copper mold, which can save you a lot of cost. Due to the advantages of smooth, durable and low-cost surface, electroplated copper mold is the most commonly used plastic mold.
3. Aluminum mold
Machined from aluminum ingots (lathes, milling machines, CNC, etc.). Aluminum molds have high precision, smooth surface and durability, but the price is very expensive. Aluminum molds are generally used on plastic products that cannot be achieved by copper molds with higher precision requirements.
