Valve gate injection molding.

Until recently valve gates had been chosen primarily for applications where thermal gate vestige is unacceptable. Once this specific amount passes through the barrel of the injection molding equipment and out the nozzle the valve gate closes instantly preventing any more plastic from passing through. Valve gate hot runner nozzles were introduced to the injection molding industry shortly after the first hot runner systems appeared on the market. The valve gate shuts off the flow of molten plastic to the mold at a specific time right at the part surface.

Mold designs using hot runner thermal gated systems and valve gate systems are often specified to provide the utmost in high performance molding. They will produce very consistent shot to shot repeatability faster cycle times good automatic mold operation and better part quality. Husky injection molding systems is the world s largest brand name supplier of injection molding equipment and services to the plastics industry. A key component of such a system is the valve gate.

The injection molding is programmed as to how much plastic is needed to fill the mold. Consider gate options and location when designing parts for injection molding in injection molding each cavity in a mold must contain a small opening called a gate which allows hot plastic to enter the cavity before passing through and around its internal features until filled. This allows a part to be molded without a sprue or runner remaining on the. With one of the broadest product lines in the industry husky equipment.
