Product details

The plastic mold and blow mold ,injection blow mold .PE mold .PC mold .The hot runner is the key to the performance of the preform mold. The hot runner designed by our factory has absorbed the advanced foreign technology, combined with the needs of domestic customers, adopts the shear-free gate design, and the hot runner nozzle controls the temperature independently. (The advantages of independent control to solve the problems arising in the production process, such as whitening at the bottom and wire drawing). The mold is produced under fully automatic conditions without frequent operation by employees, so as to reduce the labor force of workers.

The key parts of the plastic mold (core, cavity, and mouth mold) adopt the mold injection cavity, and the core injection adopts the high-quality special mold steel (HRC45) pre-heated by the original Swedish factory, which ensures the service life of the mold and the bottle quality (2 million times of normal use are maintenance-free, and the maximum and minimum wall thickness difference is less than 0.10 mm). The lathe machining center is used 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 cooperate with the refrigerator, suitable preform design and suitable injection molding machine).

The new bottle preform mold structure that is completely self-developed completely discards most of the disadvantages of the past mold, and can achieve high precision, concentricity and long life of the mold, and can carry out standardization and mass production of various parts of the mold. Our mold ensures that the wall thickness difference of the tube blank is less than 0.10 mm, and the weight error is less than 0.3 g. It can produce 2-5 molds in one minute, with a service life of 2 million mold times, and the maximum mold cavity is 144.

1. The number of preform cavities ranges from one to one hundred and forty-four.

2. The preform is designed by computer simulation tensile test to improve the finished product rate of bottle blowing.

3. The world's advanced two-stage double-taper positioning technology is adopted, and each cavity is self-locking independently to ensure mold concentricity.

4. The mold injection cavity and core are made of high-quality special mold steel with preheating treatment from the original Swedish factory.

5. The threaded port is manufactured according to international standards, and the material is imported nitrided steel, with high hardness and long service life.

6. The design of hot runner is advanced and the heating temperature is uniform, which improves the quality of plastic products.

7. The shear-free gate reduces the labor intensity of workers.

8. The die life is guaranteed to be more than 2 million die times.
