cooling for injection molding

A system which constant transfers heat from the melt in the mold or heats the mold to the injection temperature is called a temperature control system. Mold temperature refers to the surface temperature of the mold cavity that comes in…

How to control injection molding part size?

How to control injection molding part size Mold and product requirements are continuously changing, which has created many difficulties in the production process of molds and products. The challenge lies in determining the best method of controlling the geometric dimensions…

mould steel corrosion reasons and solutions

Rusting plastic molds is a normal phenomenon and caused by special reasons. It is not always due to quality problems of steel products. Melt Decomposition Some plastic raw materials will release volatile gases after being heated, which are corrosive and…

SAFEGUARDING THE MOLD

SAFEGUARDING THE MOLD A mold is an extremely expensive tool. The engineers may have to spend several hundred (sometimes thousands) of hours developing and creating their products before these are ready for manufacturing. In addition to the fix expense, destroyed…

How to Identify the Plastic material?

Plastic material identification Judging thermoplastics and thermosets: All thermosets have no softening process when heated or burned, only become brittle and coked; All thermoplastics, which are heated or burned, undergo a soft melting process, but different plastics burn. The phenomenon…

Gas-assisted injection molding

Gas-assisted injection molding is an innovative technology developed on traditional injection molding. GIM (Gas-assisted injection molding) was adopted in production in the 1980s. The gas-assisted injection molding system directly injects inert gas (usually nitrogen) into the melted plastic in the…
