How to analyze and solve the quality problems of the molding machine?
The information comes from:the Internet posted on:2023-08-29
One is that the structural dimensions of the billet are incomplete.
Inappropriate flux injection should increase the amount of flux injection; Inappropriate flux injection and the mold filling ability of inappropriate flux injection should increase the mold filling pressure of the flux injection; Appropriate raw material plasticization temperature and inappropriate flux flow rate should increase the heating temperature of the injection blown hollow molding machine barrel; When the temperature of the blank forming mold is low or uneven, the mold temperature should be appropriately increased to make the temperature of each part of the mold tend to be consistent, thereby adjusting the assembly position of the mold parts.
The second is that there are flash edges in the mold blank forming.
The amount of molten material injected is too large, and the amount should be appropriately reduced. When the injection pressure is high, it should be adjusted to reduce the injection pressure; When the quality of injection molding is poor, adjustments should be made. If the temperature of the material barrel is too high, the heating temperature of the material barrel should be appropriately reduced.
Thirdly, the thickness of the billet is uneven.
The installation position of the shaft core is incorrect and needs to be adjusted. When the material temperature is uneven or low, the screw back pressure or the heating temperature of the injection blown hollow forming machine barrel should be increased. The core rod is deformed and needs to be repaired and replaced. If the injection pressure is too high, the injection pressure of the melt should be appropriately reduced.
Fourthly, the appearance quality of the billet is poor.
There are many miscellaneous items inside the raw materials, and there are many stripes on the appearance of the blank, which are irregular. The raw materials should be replaced and pure materials should be used; The injection melting temperature is low, and the appearance of the blank is not bright. The heating temperature of the injection blown hollow molding machine barrel should be increased.
