What is a good place to find an inejction mold maker in china;

First yuou need to know what a mold is;

a Mold or die are the common terms used to describe the tool used to produce plastic parts in INJECTION moulding.

Since moulds have been expensive to manufacture, they were usually only used in mass production where thousands of parts were being produced. Typical moulds are constructed from hardened steel, pre-hardened steel, aluminium, and/or beryllium-copper alloy. The choice of material to build a mould from is primarily one of economics; in general, steel moulds cost more to construct, but their longer lifespan will offset the higher initial cost over a higher number of parts made before wearing out. Pre-hardened steel moulds are less wear-resistant and are used for lower volume requirements or larger components; their typical steel hardness is 38–45 on the Rockwell-C scale. Hardened steel moulds for plastic molding china are heat treated after machining; these are by far superior in terms of wear resistance and lifespan. Typical hardness ranges between 50 and 60 Rockwell-C (HRC). Aluminium moulds can cost substantially less, and when designed and machined with modern computerised equipment can be economical for moulding tens or even hundreds of thousands of parts. Beryllium copper is used in areas of the mould that require fast heat removal or areas that see the most shear heat generated. Steel molds can be manufactured either by CNC machining or by using electrical discharge machining processes.

Now the question rises where can you find a good plastic injection molding china company?

there are several ways to find one: 1> visiting trade fairs,  on the internet, visiting mold city's such as yuyao, dongguan shenzhen, ningbo areas on mainlan china .
