使用高速切削加工模具：

Using high-speed cutting molds:

生产中广泛使用的高速切削机床的速度约为每分钟15，00025，000转。使用高速切割可以将加工效率提高10倍以上，缩短成型时间。高速切割和精加工后的模具表面只需稍加抛光即可使用，节省大量研磨抛光时间。

The speed of the high-speed cutting machine widely used in production is about 15000 to 25000 revolutions per minute. The use of high-speed cutting can increase processing efficiency by more than 10 times and shorten molding time. The surface of the mold after high-speed cutting and precision machining only needs to be slightly polished to use, saving a lot of grinding and polishing time.

使用铝合金材料制作塑料模具：

Using aluminum alloy materials to make plastic molds:

铝合金材料因其重量轻、切削性能好、导热系数高等特点，在制造塑料模具中得到越来越多的应用。使用铝合金材料制作模具可以在缩短成型周期和降低成本方面取得良好的效果。国外有厂家生产塑料模具用铝合金材料。铝合金制成的塑料模具使用寿命为100万次。如果对型腔表面进行化学处理，使用寿命可达000万200万次。

Aluminum alloy materials are increasingly being used in the manufacturing of plastic molds due to their lightweight, good cutting performance, and high thermal conductivity. Using aluminum alloy materials to make molds can achieve good results in shortening the molding cycle and reducing costs. There are foreign manufacturers producing aluminum alloy materials for plastic molds. The service life of plastic molds made of aluminum alloy is 1 million times. If the surface of the mold cavity is chemically treated, its service life can reach 10 to 2 million times.

使用锌基低熔点金制作模具：

Using zinc based low melting point gold to make molds:

使用低熔点合金制作模具具有成本低，成型周期短的优点。特别是，这种成型方法与快速成型技术的结合是有效的。使用低熔点合金的快速成型方法特别适用于大型盖板模具和大型吹塑和吸塑模具的快速制造。当用于盖板模具时，可以快速生产样品。另一方面，当用作正式的硬模制造实验时，可以避免造成无法弥补的缺陷。由低熔点合金制成的泡罩和吹塑模具的使用寿命为 50，000 件。这种成型方法的另一个优点是材料可以在模具报废后熔化和重复使用。

The use of low melting point alloys to make molds has the advantages of low cost and short forming cycle. Especially, the combination of this molding method and rapid prototyping technology is effective. The rapid prototyping method using low melting point alloys is particularly suitable for the rapid manufacturing of large cover plate molds and large blow molding and vacuum molding molds. When used for cover plate molds, samples can be produced quickly. On the other hand, when used as a formal hard mold manufacturing experiment, it can avoid causing irreparable defects. The service life of bubble caps and blow molding molds made of low melting point alloys is 50000 pieces. Another advantage of this molding method is that the material can melt and be reused after the mold is scrapped.

如环氧树脂模具、喷涂成型模具、氮气瓶等。环氧树脂镶嵌钢模具用于汽车面板模具。热喷涂法用于制造模腔，主要用于生产聚氨酯泡沫，在聚氨酯工业中得到了广泛的应用。氮气筒在冲压模具上的应用可以有效简化模具结构，提高冲压工艺性能。

Such as epoxy resin molds, spray molding molds, nitrogen bottles, etc. Epoxy resin embedded steel molds are used for automotive panel molds. Thermal spraying method is used to manufacture mold cavity, which is mainly used to produce polyurethane foam, and has been widely used in polyurethane industry. The application of nitrogen cylinder in stamping molds can effectively simplify the mold structure and improve the stamping process performance.
