Valve Gate System & Spear System for Plastic Runnerless era

SEIKI CORPORATION, the pioneer in the field of hot runner system with a history of about 50 years in Japan, proposes systems aiming at reducing cost in the plastic mold industries via KISCO (Thailand). We provide the support system by Japanese senior engineer from SEIKI CORPORATION.

New release! Valve gate for general-purpose resin

In addition to the existing standard model, we have released a new valve gate dedicatedly for general-purpose resin. We offer a new option to minimize the cost of their products. With the support of customers, our spear nozzles for ultra-small parts have been used with a wide variety of molds for injection machines with 5-20 tons of clamping force. Our products contribute for reducing the material loss of engineering plastics.

■Principle and Features---Valve gate system

With its "topless" structure, the gate is machined directly into the cavity, which is advantageous to cooling effectiveness and transcription of its pin to make the gate marks less noticeable. For valve equipped with separate tip heater located at its front-end, the tip heater can be heated synchronously with the molding cycle to employ intermittent heating. This unique function facilitates the molding of the crystalline resins.

■Principle and Features---Spear system

Spear nozzle has long operating life because of its thermal valve principle having no sliding parts. The resin in the sprue and runner of the spear system is kept molten to maintain constant fluidity. Depending on the temperature of the gate land and a die, a very small amount of resin solidifies along with the resin inside of the cavity. After the molded product is removed, the spear tip is heated up to instantly melt the solidified resin at the gate land just before the next injection.
