the related tool technology of metal injection molding

Hot runner injection tool is a real no runner condensate injection mold,hot runner technology is an advanced technology of injection molding process.

Through precision design, manufacture ad control technology, let the binder in whole runner keep molten state, no flow of condensate, no salivation, do not make injection material overheating separation or degradation. The structure of hot runner mainly have main runner nozzle, runner plate, nozzle, heating and temperature measuring element, mounting and fastening parts. Because of high difficulty of technology, at present, whole hot runner system is design manufactured by specialy company. The whole complicated hot runner tool is common design and manufactured by injection tool enterprise with rich experience and hot runner equipment company, to ensure successary do injection.

The characteristics of hot runner tool:
-the structure of system tool is complex, high-cost, suit to mass production;
-use hot runner system,in no runner binder release tool process, the whole injection process is easy to realize automation control;
-have no cycle binder to mix, promote the stability of production process, improve product quality consistency in mass production;
-reduce the pressure loss in runner, lower its injection pressure, reduce the residual stress of the product, reduce the deformation;
-Dwell time longer and effective to reduce the shrinkage of injection parts, parts of the density more evenly;
-can manufacture more big, thin all, complicated structure,high precision parts;
-compare with normal MIM tool which can't use latent gate combination,it reduce injection gate step, improve production efficiency;
-reduce energy,mass production and reduce cost.
