Process settings of a injection molding simulation study

The Process Settings process settings icon command enables you to apply an Injection Time, Melt Temperature, Surface Mold Temperature, and Shrinkage Allowance, to solve the simulation. You can use the default settings that come from the material database or are calculated automatically during the simulation. If you modify them, stay within the values recommended by the material manufacturer.

The process settings include an automatic packing pressure stage. It determines the packing pressure level and duration based on the filling pressure and solidification time of the part.

Process settings affect the cycle time, part quality, surface finish, and energy costs. Factors that influence process settings include materials and part design.

Injection time

The time it should take to completely fill the mold with material.

Melt temperature

The actual temperature of the melted plastic as it exits the nozzle and enters the mold.

Mold surface temperature

The actual temperature of the mold at the mold/part interface, which impacts cycle time and part quality.

Material shrinkage

Shrinkage is a reduction in the dimensions of a plastic part compared with the mold dimensions. Variations in shrinkage within the part cause warp issues.

Select Compensate for Shrinkage to make the mold cavity size larger than the part design size to compensate for the expected material shrinkage.
