使用高速切削加工模具：

Using high-speed cutting molds:

生產(chǎn)中廣泛使用的高速切削機(jī)床的速度約為每分鐘15，00025，000轉(zhuǎn)。使用高速切割可以將加工效率提高10倍以上，縮短成型時(shí)間。高速切割和精加工后的模具表面只需稍加拋光即可使用，節(jié)省大量研磨拋光時(shí)間。

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.

使用鋁合金材料制作塑料模具：

Using aluminum alloy materials to make plastic molds:

鋁合金材料因其重量輕、切削性能好、導(dǎo)熱系數(shù)高等特點(diǎn)，在制造塑料模具中得到越來越多的應(yīng)用。使用鋁合金材料制作模具可以在縮短成型周期和降低成本方面取得良好的效果。國(guó)外有廠家生產(chǎn)塑料模具用鋁合金材料。鋁合金制成的塑料模具使用壽命為100萬(wàn)次。如果對(duì)型腔表面進(jìn)行化學(xué)處理，使用壽命可達(dá)000萬(wàn)200萬(wàn)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.

使用鋅基低熔點(diǎn)金制作模具：

Using zinc based low melting point gold to make molds:

使用低熔點(diǎn)合金制作模具具有成本低，成型周期短的優(yōu)點(diǎn)。特別是，這種成型方法與快速成型技術(shù)的結(jié)合是有效的。使用低熔點(diǎn)合金的快速成型方法特別適用于大型蓋板模具和大型吹塑和吸塑模具的快速制造。當(dāng)用于蓋板模具時(shí)，可以快速生產(chǎn)樣品。另一方面，當(dāng)用作正式的硬模制造實(shí)驗(yàn)時(shí)，可以避免造成無法彌補(bǔ)的缺陷。由低熔點(diǎn)合金制成的泡罩和吹塑模具的使用壽命為 50，000 件。這種成型方法的另一個(gè)優(yōu)點(diǎn)是材料可以在模具報(bào)廢后熔化和重復(fù)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.
