眾所（suǒ）周知，注塑模具材料的選擇決定了其質量，而注塑是塑料成型加工中（zhōng）不可缺少的環節，其在模具（jù）總產量中（zhōng）的比重逐年增加。它占整個成型模具的33%左右，因（yīn）此它在國民經濟中的地位越來越重要。

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、模具加工質量、模具工作狀態、產品零件狀態等。在這（zhè）個（gè）過程（chéng）中，模具材料（liào）本身的性能和熱處理起著關重要的作用。.

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（duō）數碳鋼模具鋼（gāng）因其低廉、使用方（fāng）便（biàn）、具有一定（dìng）的力學性能而被廣泛使用。除塑料模（mó）具鋼外，還包括預（yù）硬化塑料模具鋼等其他（tā）模具鋼。其中，模具鋼的種類很多。目前常用（yòng）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（mó）具鋼（gāng）是加工鋼材時應用的硬度規則。這種鋼具有優良的切削性能（néng），可在型腔內直接加工。一般用於大（dà）量塑料製品的加工，如鏡（jìng）麵模具等，以32~40HRC來計算硬度（dù）。

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（zhù）塑製（zhì）品質量（liàng）好，要（yào）求（qiú）型腔表（biǎo）麵粗糙度值小。如（rú）果要求注射腔的表麵粗糙度小於Ra0.1-0.25，光學表麵（miàn）要求小於Ra0.01nm，則（zé）需要對腔體進行拋光以降低（dī）表（biǎo）麵粗糙度。因此，選用的鋼材要求材料雜質少，排列均勻，無纖維取向，拋光時無麻點或橘（jú）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（zhù）塑模具中零件的形狀往往很複雜，淬火後很難再加工（gōng）。因此，應盡（jìn）可能（néng）選擇熱穩定性好的材料。塑料模具成型（xíng）和熱處理後，由於線膨脹係數小，熱（rè）處理變形小，溫差引起的標準變化（huà）率小，金相排列和標準模具穩定，可以減少（shǎo）或停止加工，標準精度和表麵（miàn）塑料模具的質（zhì）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，濟南注塑加工廠家提醒，定製的注塑模具產品一（yī）般都比較新穎好看。它是（shì）客戶根據自己的需要設計的（de）獨（dú）特產品。然後將產品的（de）3D圖（tú）像送注塑模具廠進行加工，並在前期（qī）簽訂保密合同。確保產品的外觀和結構不會泄（xiè）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.
