Shenzhen Jtotal Electrical Appliance Co., Ltd. was founded in August 2014, is located in the new SANYO Industrial Park in Shenzhen Baoan District City manhole Zhengnan loop. It covers an area of 15000 square meters, used for molding and injection molding; Jtotal focused on injection mold industry, improve the product engineering analysis and mold design ability, there are more than 20 years of export mold mold technology background and rich experience in manufacturing, lean and professional management team engaged in large-scale mold and precision mold development and manufacturing, mold and products exported to Europe, America, Australia, New Zealand, the Middle East, Japan and other countries and widely used.

Plastic injection molding materials are commonly used:

1., easy to process mold parts, mostly made of metal materials, and some of the structure is also very complex, in order to shorten the production cycle, improve efficiency, require mold materials easy to process into the shape and precision required by the drawings.

2. in order to raise the effect of small heat treatment hardness and wear resistance, the general of the injection mold to heat treatment, but the treatment should be very little change in size. Therefore, it is better to use pre hardened steel for cutting.

3. high corrosion resistance, a lot of resin and additives on the cavity surface corrosion, this corrosion makes the cavity surface metal corrosion and exfoliation, surface condition worse, plastic parts quality deterioration. Therefore, it is better to use corrosion resistant steel, or to the surface of the cavity chrome plated, cymbal nickel treatment.

4. good dimensional stability, injection molding, the injection mold cavity temperature of more than 300 degrees celsius. For this reason, it is better to choose the tool steel (heat treated steel) which has been properly tempered. Otherwise, the microstructure of the material will be changed, resulting in the change of the injection mold size.

5. good polishing performance, injection molding parts usually require good gloss and surface state, so the required cavity surface roughness is very small, so that the cavity surface must be surface processing, such as polishing, grinding and so on. Therefore, the choice of steel should not contain rough impurities and pores.

6. good wear resistance and surface gloss of precision plastic injection molding has a direct relation with the wear resistance of the mold cavity surface, especially some plastics added glass fiber, inorganic fillers and certain pigments, and they melt together in the flow passage, the cavity of high velocity flow, large friction on the cavity surface if the material, do not wear, will soon wear, the quality of plastic damage.

From above is calculated according to the mold technology more than 20 years of experience in the conclusion of today and we come here, we want to know more about the knowledge of injection mold, please pay more attention to our official website: www.sz-jto.com
