眾（zhòng）所周知（zhī），注塑模具材料的選擇決定了其質量，而注塑是塑（sù）料成型（xíng）加（jiā）工中不可缺少的環節，其在模具總產量中的比重逐年（nián）增加。它占整個成型模具的33%左右（yòu），因（yīn）此（cǐ）它在國（guó）民（mín）經濟（jì）中的地（dì）位越來越重（chóng）要。

As we all know, the choice of injection mold materials determines its quality, and injection molding is an indispensable link in plastic molding processing, and its proportion in the total mold output is increasing year by year. It accounts for about 33% of the whole forming mold, so it plays a more and more important role in the national economy.

影響塑件模具（jù）壽命的主要因素有：模具結構、模具材料、模具加工（gōng）質（zhì）量、模具工（gōng）作狀態、產品零件狀態等。在這個過程中，模具材料本身的性能和熱處理起著至關重要的作用。.

The main factors that affect the service life of plastic parts mold are: mold structure, mold material, mold processing quality, mold working status, product parts status, etc. In this process, the performance and heat treatment of die materials play a crucial role

目前，大多數碳鋼模（mó）具鋼因其價格低廉、使（shǐ）用方便、具有一定的力學性能而被廣泛使用。除塑料模具鋼外，還包括預硬化塑料模具鋼等其他模具鋼。其中，模具鋼的種類很多。目前常用的有預硬塑料模具鋼、滲碳塑料模具（jù）鋼和時效硬化塑料模具鋼。硬化塑料模具鋼是加（jiā）工（gōng）鋼（gāng）材時應用的硬度規則。這（zhè）種鋼具有優良的切削性能，可在型腔內直（zhí）接加工。一般（bān）用於大量塑料製品的加工（gōng），如（rú）鏡麵模具（jù）等，以32~40HRC來計算（suàn）硬度。

At present, most carbon steel die steels are widely used because of their low price, convenient use and certain mechanical properties. In addition to plastic die steel, it also includes pre hardened plastic die steel and other die steel. There are many kinds of die steel. At present, there are pre hardened plastic die steel, carburized plastic die steel and age hardening plastic die steel in common use. Hardened plastic die steel is the hardness rule applied when processing steel. This kind of steel has excellent cutting performance and can be machined directly in the mold cavity. It is generally used for the processing of a large number of plastic products, such as mirror mold, and the hardness is calculated by 32~40hrc.

注塑（sù）製品質量好，要求型腔表麵粗糙度值小。如果要求注射腔的表麵粗糙度（dù）小於Ra0.1-0.25，光學（xué）表麵要求（qiú）小於Ra0.01nm，則需（xū）要對腔體進行拋光以降低表（biǎo）麵粗（cū）糙度。因（yīn）此，選用的鋼材要求材料雜質少，排列均（jun1）勻，無纖（xiān）維取向，拋光時無麻點或橘皮缺陷。

The quality of injection molded products is good, and the surface roughness of the mold cavity is required to be small. If the surface roughness of the injection cavity is required to be less than ra0.1-0.25, and the optical surface is required to be less than ra0.01nm, the cavity needs to be polished to reduce the surface roughness. Therefore, the selected steel requires less impurities, uniform arrangement, no fiber orientation, and no pitting or orange peel defects during polishing.

注塑模具中零件的形狀往往很複雜，淬火後很難再加（jiā）工。因（yīn）此，應盡可能選擇熱（rè）穩定性好的材料。塑料模具成型和（hé）熱處（chù）理後，由於（yú）線膨脹係數小，熱處理變形小，溫差引起（qǐ）的（de）標準變化率小，金相排列和標準模具穩定，可以減少或停止加（jiā）工，標準精度和表麵塑料模具的質量可以保證。粗糙度要求。

The shape of parts in injection mold is often very complex, and it is difficult to reprocess after quenching. Therefore, materials with good thermal stability should be selected as far as possible. After plastic mold forming and heat treatment, due to small linear expansion coefficient, small heat treatment deformation, small standard change rate caused by temperature difference, stable metallographic arrangement and standard mold, processing can be reduced or stopped, and standard accuracy and surface plastic mold quality can be guaranteed. Roughness requirements.

另外，濟（jì）南注（zhù）塑加工廠家提（tí）醒，定製的注塑模具產品一般都（dōu）比較新穎好看（kàn）。它是客戶根據自己的需要設計的獨特產品。然後將產（chǎn）品的3D圖像送（sòng）至注（zhù）塑模具廠進行加工，並在前期簽訂保密合同。確保產品的外觀和結構不會泄漏。

In addition, Jinan injection molding manufacturers remind that customized injection mold products are generally novel and good-looking. It is a unique product designed by customers according to their own needs. Then send the 3D image of the product to the injection mold factory for processing, and sign a confidentiality contract in the early stage. Ensure that the appearance and structure of the product will not leak.
