Hot Runner Plastic mold began to promote

Manufacturing precision plastic injection mold cavity up to 0.02 ~ 0.05mm, surface roughness Ra0.2μm, Plastic mold quality, life significantly improved , non- hardening steel life of up to 10 to 30 million times , hardened steel up to 50 ~ 10 million times , shorter delivery time than before , but still lags behind and abroad , specific data in Table 1.

Molding process, the multi-material molding Plastic mold , efficient multi-color injection mold , insert mold interchangeable core pulling mechanism structure and innovative design has also made great progress. Gas-assisted injection molding technology using more mature , and other manufacturers succeeded in 29 to 34 inch TV and some thick-walled shell parts Plastic mold on the use of gas-assisted technology , some manufacturers also used the C-MOLD gas-assisted software , to achieve better results.

Companies such as able to provide users with gas assisted injection molding equipment and technology . Hot Runner Plastic mold began to promote , and some plants using rate of 20 or more , the general -heat or hot outside hot runner device , a few units using the world's advanced level of difficulty valve gate device , a few units using the world advanced level of difficulty valve gate Plastic mold.

But overall runner adoption rate of less than 10 , and 50 to 80 compared to abroad , gap. In manufacturing technology , CAD / CAM / CAE technology level to a new level, to produce household appliances enterprises represented have introduced a considerable number of CAD / CAM systems .
