Eternal life pursues the highest mold performance. Produce high quality preforms and use corrosion resistant steel to optimize preform production. Yongsheng mold has a long life. The mold design guarantees quick and easy maintenance. Yongsheng molds are easy to use, and regular maintenance work can be done directly on the machine in the shortest possible time. Mold parts are easy to replace and can produce different preforms on the same mold. Hard mold parts guarantee mold life and minimize maintenance. We can product 2-16 cavity 5 gallon self-lock preform mould, it can blow 20L 30L 40L 50L and more bigger bottle. At present, there are three series of PET preform molds, including double lock pneumatic needle valve tube blank mold. Double lock adjustable eccentric pneumatic needle valve preform mold, ordinary no-gate preform mold. The company uses advanced CAD for mold-assisted design. The shape of the preform is optimized for the final plastic bottle to ensure the final plastic molding quality. The double-lock pneumatic needle valve tube blank mold and the double-lock adjustable eccentric pneumatic needle valve preform mold adopt multi-dimensional cone positioning system to ensure the plastic thickness of the plastic bottle is consistent. At the same time, the unique hot runner system of Yongsheng Mould ensures the same pressure and PET flow ratio of each cavity.
