72 Cavity PET Preform Mould
We are one of the reliable companies in this field, offering PET preform molds with advanced PET preform mold design technology.
1. Material
Custom Material 632: Better than FS136 with higher nickel and chromium content.
Toughness, rust resistance, and whitening effect are obviously improved.
The mold base is made of HRC 38~40 stainless steel or P20 (pre-hardened).
2. Stack design of SelfLock type
Before closing the mold, the parting seam is locked in place by a locking ring to minimize parting line wear on the cavity side and core side, thereby extending the burr-free life of the parting line.
3. Cooling system
The core adopts fountain or spiral cooling structure.
Spiral waterways are used for milling outside the cavity, improving cycle efficiency and reducing cleaning time.
The neck is drilled with cross cooling channels.
Each plate is individually designed with circulating cooling channels.
An optimized cooling layout is used to ensure fast and efficient heat exchange between steel and water and supports fast cycle times to save energy costs.
48-cavity air-sealed PET preform mold
1. Professional and technical experience in preform mold cavities ranging from 1 to 96 cavities.
2. The preform mold uses CAD software to design the preform shape according to the bottle to ensure the molding quality of the bottle.
3. The thread opening material of the preform mold is made of imported nitrided steel, manufactured according to international standards, with high hardness, each thread is ventilated, and has a long service life without deformation.
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 can be independently temperature controlled, heated, and the temperature is uniform.
6. Cut-free gate preform mold, saving labor and raw materials.
7. The temperature of the hot runner nozzle is controlled separately. (To solve the problem of whitening and wire drawing at the bottom during the production process).
8. Needle-valve self-locking preform mold: each core, cavity, independent double self-locking, adjustable eccentricity, reduce eccentricity, ensure product concentricity, high precision. The mold has a long service life.
9. Support sample and drawing processing, provide new product development, one-stop service for injection molding processing!
48-cavity air-sealed PET preform mold
1. Mold features:
1. We specialize in the production of needle valve moulds, which do not require manual cutting.
2. The use of advanced hot runner system ensures that the AA value of the product is at a low level.
3. Reasonable cooling water channel design strengthens the cooling effect of the mold and effectively shortens the injection molding cycle.
2. Material selection:
1. The main parts of the mold are made of imported S136 material (Sweden-Sabak).
2. The mold base material adopts imported P20 material and electroplating 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 in a vacuum furnace imported from Germany, and the hardness of the parts is guaranteed to be at HRC45°-48°.
4. Advanced processing equipment:
The company has introduced a number of machine tools imported 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 weight error is less than 0.3g, 2-5 molds can be produced in one minute, and the service life can reach 2 million mold times.
24 cavity preform mold
The new preform mold structure independently researched and developed can completely eliminate most of the disadvantages of the past molds, and can achieve high-precision concentricity and long life of the mold, and can carry out standardization of various parts of the mold and mass production. Our molds ensure that the wall thickness difference of the tube blank is less than 0.05mm, and the weight error is less than 0.3g. 2-5 molds can be produced in one minute, and the service life can reach 2 million mold times. The mold has a maximum of 96 cavities.
