            塑料模具鋼材料具體有什么

            如今為避免模具零件在強韌化過程中的變形或其他熱處理問題,模具鋼以預硬化形式供應市場已較普遍。而塑料模具鋼性能要求嚴格,質量更高,加工精良,對熱處理有利。下面我們就來看看山東塑料模具鋼材料具體有什么吧。
            Nowadays, in order to avoid deformation or other heat treatment problems of mold parts in the process of strengthening and toughening, it is common for mold steel to be supplied to the market in the form of pre hardening. The plastic die steel has strict performance requirements, higher quality and better processing, which is beneficial to heat treatment. Let's take a look at the specific materials of Shandong plastic mold steel.
            一、易切削、拋光性好的塑料模具鋼。這類鋼的雜質少,組織微細均勻、無纖維方向性,制模后型腔的表面質量高。
            1、 Plastic die steel with easy cutting and good polishing. This kind of steel has less impurities, fine and uniform structure, no fiber directivity, and high surface quality of the cavity after molding.
            二、預硬化型塑料模具鋼。該類剛應用廣泛,以預硬化處理后的鋼塊供貨,硬度達到23~48HRC,加工型腔后不再處理,無變形,可以縮短模具制造周期。代表鋼號有:
            2、 Pre hardened plastic die steel. This kind of steel is widely used. It is supplied with steel blocks after pre hardening treatment. The hardness reaches 23 ~ 48hrc. After processing the cavity, it is no longer processed and has no deformation, which can shorten the mold manufacturing cycle. The representative steel grades are:

            三、時效硬化型塑料模具鋼。這種鋼一般碳含量較低,鋼種加入Ni、Al、Ti、Cu、Mo等元素,模具坯料先經固溶后,在低硬度下進行加工,成形后進行時效處理,由于金屬間化合物的析出,使模具硬度提高到40~50HRC,以滿足使用要求。由于時效溫度低,變形小而具有規律,適于制造形狀復雜、精度高、超鏡面以及大型塑料模具尤其是熱塑性塑料制品用模具。時效硬化型塑料模具鋼有馬氏體時效硬化鋼和析出(沉淀)硬化鋼兩大類。
            3、 Age hardening plastic die steel. This kind of steel generally has a low carbon content. Ni, Al, Ti, Cu, Mo and other elements are added to the steel. The mold blank is processed under low hardness after solid solution, and then aged after forming. Due to the precipitation of intermetallic compounds, the hardness of the mold is increased to 40 ~ 50HRC to meet the use requirements. Due to low aging temperature, small deformation and regularity, it is suitable for manufacturing complex shapes, high precision, super mirror surfaces and large plastic molds, especially molds for thermoplastic products. Age hardening plastic die steels include martensitic age hardening steels and precipitation hardening steels.
            四、整體淬硬型塑料模具鋼。國外一般都是借用高耐磨性冷作模具鋼和熱作模具鋼。如美國的A2(Cr5Mo1V)、D3(Cr12)、D2(Cr12Mo1V)等冷作模具鋼和H13(4Cr5MoSiV1)等熱作模具鋼。
            4、 Integrally hardened plastic die steel. Cold working die steel and hot working die steel with high wear resistance are generally used abroad. Such as A2 (Cr5Mo1V), D3 (Cr12), D2 (cr12mo1v) and other cold work die steels in the United States and H13 (4Cr5MoSiV1) and other hot work die steels.
            五、耐腐蝕塑料模具鋼。有些塑料制品如聚氯乙烯、氟塑料、阻燃塑料等,在加工過程中對模具具有腐蝕作用,因此一般采用馬氏體不銹鋼和沉淀硬化型不銹鋼。
            5、 Corrosion resistant plastic die steel. Some plastic products, such as PVC, fluoroplastics, flame-retardant plastics, etc., have corrosive effects on the mold during processing, so martensitic stainless steel and precipitation hardening stainless steel are generally used.
            當塑料制品的產量不大、要求不高時,可以在模具表面采取鍍鉻保護措施,但大多數情況需采用耐腐蝕鋼制造模具。
            When the output of plastic products is not large and the requirements are not high, chromium plating protection measures can be taken on the mold surface, but in most cases, corrosion-resistant steel should be used to make the mold.
            六、無磁塑料模具鋼。為了適應磁性塑料制品的生產,國外發展了一些無磁塑料模具鋼,將模具鋼通過時效硬化處理得到符合要求的硬度、強度和低導磁率。
            6、 Non magnetic plastic die steel. In order to adapt to the production of magnetic plastic products, some non-magnetic plastic die steels have been developed abroad. The die steels are age hardened to obtain the required hardness, strength and low permeability.
            在選購時,要注意選用正規廠家出廠的模具鋼,要求廠家提供相關的質量保證書等,避免選擇到不合適的材料。更多相關內容就來我們網站http://www.environmentandpeople.net咨詢吧!
            When purchasing, pay attention to the selection of die steel from regular manufacturers, and require the manufacturers to provide relevant quality certificates, so as to avoid selecting inappropriate materials.
