How to Solve the Unstable Quality of Blowing Products of Injection Blowing Hollow Molding Machine

How to solve the problem of unstable quality of blowing products? You know what? Today, let's learn about the problems and solutions of the injection blow hollow molding machine!
The quality of the blown products of the injection blow hollow molding machine is unstable:
The thin wall of parison is uneven, and the thin wall of blown products is uneven, which is easy to be blown out. If the die expanding pressure is too large, the die expanding pressure should be appropriately reduced; If the die expansion temperature is too high, adjust and reduce the temperature of the mandrel and die; The position of expansion mold air inlet is unreasonable and should be corrected.
The products of the injection blow hollow molding machine are dull or difficult to demould:
The temperature of the forming die is uneven, and the temperature difference of each part is large, so the mold heating temperature control system should be adjusted or corrected; If the working surface of the forming die has foreign matters or is not smooth, it should be cleaned or polished.

The product bottom of the injection blow hollow molding machine turns white:
When the mold temperature inflation is low, adjust the temperature of all parts of the mold to be uniform; When the gate temperature is low, the gate temperature or molten material temperature shall be appropriately increased.
Deformation of bottle neck:
In the case of short cooling time, the melt expansion shall be extended appropriately. The temperature at the neck of the forming die is too high, so the die temperature should be appropriately reduced. If the temperature of steel core is too high, the temperature shall be reduced appropriately; The temperature of mold cooling circulating water is too high, so the water temperature should be appropriately reduced.
