The template is made of stainless steel or P20 pre-hardened, and the P20 template is nickel-plated, with a Rockwell hardness of 38-40 degrees.
-The core, cavity and screw are made of Sweden ASSAB S136 or Germany 2316, with Rockwell hardness of 48~52 degrees.
-Graphite copper plates are inlaid between the slider and the pushing plate, between the guide post and the guide sleeve to achieve a better lubrication effect.
-Each cavity heating ring adopts Italian ROTFEL or German HOTSET.
-The thimble adopts Japanese SKD-61.
1. The weight tolerance of preform products is ±0.2g (increasing with product weight).
2. The eccentricity range of preform products is ±0.1mm (increasing with the length of the product).
3. Efficient cooling water circuit, shorter injection time.
4. Guarantee 3 million injection mould times. The main parts are matched with a double taper self-locking design, and the life of the mold in normal use can reach 3 million mold times. The optimized cooling system reduces the cycle molding time of the mold.
-Swedish ASSAB S136 or German 2316 are used for core, cavity and screw, with Rockwell hardness of 48~52 degrees.
-Mold structure design superior to other molds.
-Each cavity part adopts independent self-locking structure.
-The parts in each cavity are interchangeable, the structure is reasonable, and the maintenance is convenient.
-Ensure accurate product weight and low eccentricity.
-Imitate the HUSKY gas seal mold hot runner system to ensure high product transparency.
In order to ensure the quality of CH preform molds, the company is equipped with a projector to check the size of the preform, a hardness tester for mold parts, and a stress tester, eccentricity tester, high-precision electronic scale for the preform after injection molding, etc. Professional testing 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.
