Needle valve hot runner
Use a needle valve gate to control the gate closure with a valve needle to maintain pressure time. The gate solidification valve needle is closed, and the needle valve gate can shorten the injection cycle compared to the open gate.
Needle valve gates do not create gate marks and usually leave only an almost invisible ring. If the surface quality of the product is critical, the needle gate form is the best solution. Since the gate opening is relatively large, shear heat and pressure drop can be reduced. Needle valve gates have a low profile fill pressure and offer a wider molding window for a variety of difficult to shape thermoplastic materials. For any material, the needle gate eliminates the possibility of gate drooling.
Up to 10 types of needle valve gates are available to meet the needs of high-quality gates for a wide range of plastic parts. Precise valve needle guide structure ensures smooth operation of the valve needle and guarantees the service life of the mold. Unique gate design without dead ends The structure ensures high efficiency in color change and is suitable for white and transparent materials.
