The technical features of preform molds mainly include the following aspects:
Accurate size design: The size design of the preform mold needs to accurately match the specifications of the preform to be produced to ensure the size accuracy and consistency of the bottle.
Complex cavity structure: The cavity structure of the preform mold is complex, and factors such as the shape, wall thickness, and reinforcement ribs of the bottle need to be considered to ensure the strength and beauty of the preform.
Efficient cooling system: The design of the cooling system directly affects the cooling speed and production efficiency of the preform. Reasonable layout of cooling water channels can shorten the cooling time and improve production efficiency.
Durable material selection: Preform molds are usually made of high-strength and high-wear-resistant materials, such as high-speed steel, alloy steel, etc., to ensure the long life and stability of the mold.
Advanced manufacturing process: The manufacturing process includes steps such as design, material selection, processing, assembly debugging, and acceptance testing to ensure the precision and reliability of the mold.
Multi-cavity design: The mold has a number of cavities from 2 to 144, which improves production efficiency and the feasibility of mass production.
Corrosion-resistant materials: Stainless steel templates are used for corrosion resistance and easy mold maintenance.
Optimized cycle design: Part ejection sensors are used to monitor the operation of transferring the preforms to the pick-up plate to optimize the cycle.
Reduced wear design: The auxiliary cone reduces mold wear by pre-adjusting the half mold before the access to the die lip cone.
Standard interchangeable components: The mold components have standard interchangeability for easy maintenance and replacement.
Leak-proof design: The water pipe is diverted at the bottom of the mold to ensure leak-proofness while eliminating water marks on the preform.
Simplified maintenance design: The roller cam activates the opening and closing action of the threaded joint, which requires fewer components and simplifies mold maintenance.
Uniform temperature design: The UltraPET? hot runner design improves the layout of the heaters to make heating more uniform and reduce temperature differences.
Extended seal life design: Only one O-ring seal is used on the cooling back plate, which more than doubles the seal life and maintenance intervals.
