Shanghai Daoqin Plastics Co., Ltd.

can injection molding basic principle is utilizing low melting point alloy formed can type 芯, rear can type as is parts mold in injection molding, cooling rear has type made parts from type in 取出, again add hot will type 芯熔化, formed in products.

当 injection molding structure upper difficult demolding plastics parts, automotive tube/pipe and gas tube/pipe and other has complex 形状 空心 products 时, can using/adopting can injection molding.

can injection molding technology process lower:  

use low melting point metal type 芯→放入 mold injection molding →取出 belt/tape has type made parts → add hot type 芯→清洁 made parts → products.  

currently, can type injection molding technology in PA66方面积累 一定 experience, experiment/testing research table/sheet 明PA6, PBT, PET, PPO and other combined can type injection molding.

can type material using/adopting is Sn-Bi and Sn-Pb low melting point alloy. melt type generally using/adopting add hot and 感应线圈 add hot methods.  

can type injection molding advantages:

1, especially suitable for production complex, in 空, machine processing composite/compounding material products.

2, in parts internal dimensions 精确, surface light 洁, this is method use usually methods achieve.

3, and blow molding and gas injection molding versus ratio, although need increase can type equipment and type equipment, can separation utilizing has injection molding machine, molding degree relatively large.

熔芯 injection molding process precautions:

1, parts injection molding type can melt 化.

2, type metal melt and use type 芯 介质不会腐蚀 plastics.

3, in type temperature degree lower, made parts 不会发生 deformation.
