Mold steel can be repackaged during the specific use of products.

什么是二次包装？二次包装意指该产品需要某种钢材，但是钢材的外包装并不符合实际所需要的本质，影响产品的本质有多种多样的原因，可能是外包装，也有可能是受到空气和其他成分的影响。

What is secondary packaging? Secondary packaging means that the product needs some kind of steel, but the outer packaging of steel does not meet the essence of actual needs. There are various reasons affecting the essence of the product, which may be the outer packaging or the influence of air and other components.

为了避免产品质量受到影响，部分使用者通常会选择在钢材的外表添加膜，这种膜绝大部分会采纳塑料或者塑胶。

In order to avoid the influence of product quality, some users usually choose to add film on the surface of steel. Most of this film will adopt plastic or plastic.

使用了塑料或塑胶的模具钢会跟原来的模具钢有什么不一样吗，会不会产生什么变化？其中两者之间的优势和分类又是如何？

Will the die steel made of plastic or plastic be different from the original die steel, and will there be any changes? What are the advantages and classifications between the two?

下面就给大家一一作出详细的解释。

Let's give you a detailed explanation one by one.

塑胶模具钢和塑料模具钢有哪些区别？

What are the differences between plastic mold steel and plastic mold steel?

塑胶模具钢和塑料模具钢尽管只有一字之差，但它们的属性还是有区别的。

Although there is only one word difference between plastic mold steel and plastic mold steel, their properties are still different.

塑胶模具钢有哪些？

What are the plastic mold steels?

塑胶模具钢分预硬普通塑胶模具钢，预硬塑胶模具钢，预硬高硬度塑胶模具钢，预硬抗腐镜面塑胶模具钢，抗腐镜面塑胶模具钢五小类。

Plastic mold steel is divided into five categories: pre hardened ordinary plastic mold steel, pre hardened plastic mold steel, pre hardened high hardness plastic mold steel, pre hardened anti-corrosion mirror plastic mold steel and anti-corrosion mirror plastic mold steel.

渗碳型塑料模具钢：P1，P2，P3，P4，P5，P6。这类钢含碳量很低，主要是美国早期及用挤压成型制模法，要求冷塑性好，有高的挤压性能，成型后表面渗碳淬火提高表面硬度，使用寿命长。芯部超低碳可使淬火时变形量也更小。

Carburized plastic die steel: P1, P2, P3, P4, P5, p6. The carbon content of this kind of steel is very low, mainly in the early United States and the extrusion molding method, which requires good cold plasticity and high extrusion performance. After forming, the surface carburization and quenching can improve the surface hardness and long service life. Ultra low carbon in the core can reduce the deformation during quenching.

调质型塑料模具：P20，P21。塑料模具中P20的用量很大，已成为主体，大多数在预硬状态时使用。中碳合金工具钢用于热固性塑料模。钢号有H13，而L2和S7，O1和A2也有应用。

Quenching and tempering plastic mould: P20, p21. The amount of P20 in plastic mold is very large, which has become the main body, and most of them are used in the pre hardening state. Medium carbon alloy tool steel is used for thermosetting plastic molds. Steel grades are H13, while L2 and S7, O1 and A2 are also used.

不锈钢用于耐蚀性要求高的塑料模，主要钢号有420，414L，440，416。

Stainless steel is used for plastic molds with high corrosion resistance requirements. The main steel grades are 420414l and 440416.

时效钢是经过时效处理而获得高的使用性能钢材。

Aging steel is a kind of high performance steel obtained by aging treatment.

低碳Ni-A1时效钢；18Ni马氏体时效钢是用于宇航工业的无碳纯度高、高强度、高韧性的材料。用于力学性能、尺寸精度、光洁度和耐蚀性都要求高的塑料模具。

Low carbon Ni-A1 aging steel; 18Ni Maraging steel is a carbon free material with high purity, high strength and high toughness used in aerospace industry. It is used for plastic molds that require high mechanical properties, dimensional accuracy, finish and corrosion resistance.

如何采用塑料模具钢？

How to use plastic die steel?

1.薄壁的塑料箱体，生产批量在小于10万件时，用P20，P21预硬态（HB250～300），腐蚀性较强时用414L。

1. For thin-walled plastic boxes, when the production batch is less than 100000 pieces, P20 and p21 are used for pre hardening (hb250 ~ 300), and 414l is used for strong corrosion.

2.高寿命的普通塑料模，用P6或P20，经渗碳一淬火后硬度在HRC54-58，塑料件不太大时，可用O1、S7。腐蚀性较强时用420。

2. P6 or P20 is used for ordinary plastic mold with high service life. After carburizing and quenching, the hardness is hrc54-58. When the plastic part is not too large, O1 and S7 can be used. 420 for strong corrosivity.

3.非高温的热固性模用P6，P20经渗碳淬火后使用。腐蚀性强用420。

3. P6 and P20 for non high temperature thermosetting die are used after carburizing and quenching. Highly corrosive 420.

4.高温热固性塑料模用H13和S7或渗碳钢P4。这些含铬较高有好的抗回火性和抗高温氧化性。

4. H13 and S7 or carburized steel P4 for high temperature thermosetting plastic mold. These contain high chromium and have good tempering resistance and high temperature oxidation resistance.
