CAM

plastication

Software; CAM

Plastication is the process in which raw material is changed to melt and pushed to the front of the screw through a rotational action.

pvt

Software; CAM

Pressure-Volume-Temperature (PVT) data describes the specific volume (1/density) of a material as a function of temperature and pressure. It describes the temperature/pressure relationship for ...

process control

Software; CAM

Process control is the monitoring and correction of production.

Dark colored brown or silver streaks can be caused by thermal damage to the material during filling, or inadequate tool venting. Rectify the venting system, or reduce the injection speed or pressure ...

streak mark - glass fiber

Software; CAM

Rough and mat streaks can be caused by differential shrinkage or premature freezing of glass-filled material against the mold wall. Using shorter glass fibers, increasing melt temperature, or ...

streak mark - color

Software; CAM

Usually occurs because of different orientation of the pigments in the flow, or poor blending in the plastication stage.

sink mark

Software; CAM

A defect on the surface of a molded part. Sink marks are caused mainly by thermal contraction (shrinkage) during packing, if the temperature and pressure are not controlled correctly. They can occur ...
