Cold runner product used when molding LSR. If the circulation path is too hot, the compound may start to furniture mouldcure before injection. Some mold makers have designed an open cold runner system that's so small that it must set multiple injection points (and thus the complete cavity) within an extremely restrained mold space.

In many conditions, the non-injected rubber track system also reduces the operating time frame. This technology assists you to mass-produce high-quality silicone rubber goods without separating the nozzles. However, in case cooled too quickly, it will absorb excessive heat from the gate part of the mold, resulting in imperfect vulcanization.

The rubber injection nozzle is controlled with a needle valve for forward flow.Vacuuming within the mold creates the best ventilation effect.. By processing products as, it is not necessary to cut out the glue injection path, thereby avoiding increasing the labor intensity belonging to the work and sometimes avoiding a large number of material waste.

This is accomplished by designing a gasket about the parting line and quickly vacuuming every one of the cavities using a vacuum pump motor. Some injection molding equipment allow operation under varying shutting forces, which allows the processor to be able to close the mold at low pressure until 90%-95% with the cavity is filled with LSR (makes air easier to discharge) then switches to higher The shutting force prevents the silicone plastic from swelling and overflowing.
