12 30/25 caliber PET preform mold


A 12-out 30/25-caliber preform mold is specially designed for pure water beverage bottles. 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 25 grams, and the mold is matched with the CH injection molding system. With a general PET screw injection molding machine, the production cycle is 25 seconds.

The key parts of the mold (core, cavity, mouth mold) are injected into the mold, and the injection core is made of high-quality special mold steel (2316) preheated by the German original factory to ensure the service life of the mold and the quality of the bottle (normal use 2 million Maintenance-free, the wall thickness difference is less than 0.10mm). The standard mold base is 50# steel, and the slider is 718# steel. Equipped with imported high-quality lubricating copper plate, German HOTSET heating element, German standard only PID (plug-in type) hot runner temperature control box. And use turning machining center processing to ensure the processing quality of parts and realize mutual matching. The reasonable arrangement of the cooling water channel makes the mold have higher production efficiency, and the molding cycle is as short as 15 seconds (need to be equipped with a cooler, a suitable preform design and a suitable injection molding machine)

Features

 

 

Needle valve preform mould

Each cavity of the preform mold structure is independent and self-locking, and the concentricity is ≤0.08MM. The mold cavity and core are made of German 2316 mirror-surface corrosion-resistant plastic molds. The hardness can reach HRC50 and the service life is long. The threaded mouth is manufactured according to international standards, and imported nitriding mold steel is selected, the hardness reaches HRC55, the service life is long, the hot runner design is advanced, the nozzle temperature is controlled at a single point, the heating temperature is uniform, and the quality of plastic products is improved. The length of the gate without shearing gate is 0.5mm, which ensures the automatic production of the mold and reduces the labor force. Mold life is above 4.5-5 million mold times

 

 

Double self-locking preform mould

Each cavity of the preform mold structure is independent and self-locking, and the concentricity is ≤0.08MM. The mold cavity and core are made of German 2316 mirror-surface corrosion-resistant plastic molds. The hardness can reach HRC50 and the service life is long. The threaded mouth is manufactured in accordance with international standards, and imported nitriding mold steel is selected, with a hardness of HRC55, long service life, advanced hot runner design, single-point temperature control of the nozzle, and uniform heating temperature, which improves the quality of plastic products. The length of the gate without shearing gate is 1.5mm, which ensures the automatic production of the mold and reduces the labor force. The mold life is more than 4 million mold times.

 

 

Ordinary long sprue preform mould

 

Each cavity of the preform mold structure is not independent and self-locking. The mold cavity and core are made of German 2316 mirror-surface corrosion-resistant plastic molds. The hardness can reach HRC50 and the service life is long. The threaded port is manufactured in accordance with international standards, and imported nitriding mold steel is selected, the hardness reaches HRC55, and the service life is long. The hot runner design is advanced, the heating temperature is uniform, and the quality of plastic products is improved. The length of the gate of the preform is 12mm and the gate needs to be cut manually, but the mold is fully automated, and the mold life is more than 2 million molds.

 

 

Ordinary short gate preform mould

 

Each cavity of the preform mold structure is not independent and self-locking. The mold cavity and core are made of German 2316 mirror-surface corrosion-resistant plastic molds. The hardness can reach HRC50 and the service life is long. The threaded port is manufactured in accordance with international standards, and imported nitriding mold steel is selected, the hardness reaches HRC55, and the service life is long. The hot runner design is advanced, the heating temperature is uniform, and the quality of plastic products is improved. The length of the preform gate is 1.5mm, but the mold is fully automated, which reduces the labor force of the workers. The mold life is more than 2 million mold times.

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.
