A 48 PCO1810 caliber preform mold is specially designed for carbonated beverages. It adopts a needle valve type balanced hot runner system to ensure that the gate is beautiful without drawing. The design of the preform ejection convex shaft reduces the maintenance time of the mold.
The weight of the PET preform is 22 grams, and the mold is matched with the CH injection molding system. In a general PET screw injection molding machine, the production cycle is 24 seconds. The production cycle of an injection molding machine with a dual injection molding system with a 3-station out-of-mold cooling system is 12 seconds.
1: Professional technical experience in the number of cavities of the preform mold from 1 to 96 cavities.
2: The preform mold adopts CAD software to design the shape of the preform according to the bottle to ensure the forming quality of the bottle.
3: The material of the thread mouth of the preform mold is made of imported nitride steel, manufactured according to international standards, with high hardness, each thread is exhausted, and it has a long service life and does not deform.
4: Preform mold core and cavity are made of corrosion-resistant steel, which is durable.
5: The preform mold adopts advanced hot runner design, so that each cavity is independently controlled, heated, and the temperature is uniform.
6: Preform mold without cutting sprue, saving labor and raw materials.
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.

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.
