Material of preform mold

(1) The main parts of the mould are made of imported DIN 2316 materials.

(2) The mold base material is made of P20 material or No. 50 steel plating treatment, which improves the corrosion resistance of the mold and prolongs the service life of the mold.

(3) The heat treatment of the parts is processed by an imported vacuum furnace, and the hardness of the parts is guaranteed to be HRC45°-52°.

Advanced processing equipment

The company has imported processing equipment from the United States and Japan, such as machining centers, CNC lathes, EDM, etc., to ensure the machining accuracy of the parts and make the parts have good interchangeability. The product eccentricity value is ≤0.10mm (the length of the preform is within 100), The weight error is less than 0.3g. The cycle time of the 30/25 preform with 24 cavities and 16g is 18 seconds per mold, and the life span can reach 3 million molds.

Advanced detection methods

In order to ensure the quality of Chuanghong's preform mold, the company is equipped with a projector to check the size of the preform, a hardness tester for mold parts, and professional inspections for the stress detector, eccentricity detector, and high-precision electronic scale after the injection molding of the preform. equipment. The use of the above measuring equipment can ensure that our PCO1810, PCO1881, 30/25 and other standard preform calibers can reach the ISB standard.
