![]() ![]() YUNO series preform mold with double heating system ensures perfect heating effect. Lager flowing channels of such hot runner system ensures the mold to produce preform with lower injection pressure, which reduces molds each parts wear & tear and maintenance cost, and also saves electric energy. YUNO series preform injection Mould/mold adopts specially designed hot runner system to achieve ideal and prompt heating effect for preform production. YUNO adopts a wide range of computer-aided engineering service from design conception to the finished products to make customer satisfied. Welcome to contact us, GEENO Molding Co., Ltd.With decades design and manufacture experience, YUNO mould designs not only preform with standard neck size for water bottle, carbonated drink bottle and oil bottle, also design preform of special shape responding to customers request. Regularly use professional cleaning agents inside the mold cavity and conduct monthly inspections of the mold exhaust slots to prevent clogging of the exhaust holes. Mold maintenance: The cooling water channel of the PET Preform mold needs to be maintained with softened water,Īnd scaling should be cleaned in a timely manner and inspected monthly Such as robotic arms, reducers, host bearings, movable guide rails, mold guide pillars, guide sleeves, and internal and external bayonets.ģ. Mechanical lubrication: Timely replenish lubricating oil for mechanical components that require lubrication, Regular maintenance: Inspect the entire mold on time, especially for fast wear and important key components.Ģ. What should be done for the repair and maintenance of PET Preform molds?ġ. The control system includes an axial wall thickness control system and a circumferential wall thickness control system, which are used to adjust the gap between the mold lip and the mold core. The factors that affect these two phenomena include the diameter of the mold head and the wall thickness control system of the blow molding machine. ![]() The common phenomena are the expansion of the embryo from the mold and the elongation of the embryo. The material and structure of the mold the Mold exhaust system and the mold cooling system.īlanking stage. The factors that affect this situation include the shrinkage rate of the material Blowing pressure and time The common phenomenon is the deformation of the mold embryo due to high-pressure blowing,Īnd the contact deformation between the mold embryo and the mold cavity. ![]() Good grindability, low relative loss of grinding wheel, less prone to abrasion and grinding cracks.įactors affecting the formation of PET Preform mold: Conventional quenching has small volume changes, low tendency for abnormal deformation, low cracking sensitivity, and is not sensitive to quenching temperature.ĥ. After quenching, a deeper hardening layer can be obtained, and quenching can be achieved using a mild quenching medium.Ĥ. Hardening, with uniform surface hardness after quenching.ģ. When heated at high temperatures, it has good antioxidant capacity and is not sensitive to the heating medium.Ģ. Sensitivity to oxidation and decarbonization. ![]() The mold has a lifespan of at least 3 million mold cyclesġ. The excellent cooling system achieves high efficiency of constant temperature water cooling, and there is no shear gate, reducing labor intensity for workers. In addition, the PET Preform molds adopt the international advanced second-level double taper positioning technology, with each cavity independently self-locking to ensure the concentricity of the mold. They have the characteristics of energy conservation, high efficiency, and long service life. In our daily life, they are commonly used in various packaging industries such as edible oil, beverages, candy, medicine, etc. The current application of PET Preform molds is relatively common. ![]()
