common questions in plastic injection 1
1. When the machine is just started, the product runs on the edge (flying edge), and the reason and solution for the lack of glue after a period of production.
When the injection molding machine is just started, due to the long heating time, low viscosity and good fluidity of the melt glue in the material pipe, the product is easy to run around. After a period of production, the heat is constantly taken away by the melt glue, resulting in insufficient melt glue, high viscosity and poor fluidity, which makes the product lack of glue. After a period of production, gradually increase the temperature of the material pipe to solve the problem.
After a period of production, due to the continuous heat taken away by the melt glue, the melt glue is insufficient, with high viscosity and poor liquidity, resulting in the lack of glue in the product. Raise the temperature of the material pipe to solve the problem.
