48 Cavity PET Preform Mould
48-cavity pin valve PET preform mold
1. The hot runner adopts PID control system, which is characterized by automatic repair and automatic protection functions, which can prolong the service life of the electric heating device;
-The temperature is controlled within 1°C to ensure that the raw materials are not burned in the hot runner, and the finished product rate can reach more than 99%;
-The new nozzle design makes the mold easier to maintain, the thimble part of the nozzle, the heating part, the heat insulation part, and the thermocouple can be easily replaced without disassembling the mold, which is beneficial to reduce downtime and save maintenance costs.
2. Cooling system
-The spiral cavity cooling water channel makes the cooling effect stronger.
-The cooling water channel on the threaded port and the slider enhances the cooling effect.
-Exquisitely designed central distribution plate, cooling water can be evenly introduced into each cavity, and all preforms can be effectively cooled evenly and quickly.
3. Hot runner
- The hot runner with excellent balance performance ensures the flow and pressure of PET melt in all cavities are uniform.
-PET melt channeling minimizes shear and IV losses and allows PET melt to flow evenly to all cavities.
- Optimal heat distribution keeps the acetaldehyde (AA) content in all cavities stable. 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.

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.
48-cavity air-sealed PET preform mold
