How do you remove flash from plastic parts?

Hot air works well for removing flash that is thin and fine. However, if the flash is too coarse it can be difficult to melt back into the part surface without affecting the look of the finished product. In these cases the flash may need to be mechanically removed before using hot air to smooth the surface.

How do you eliminate flash?

A common first response to reduce flash is to slow down the injection rate. While decreasing the injection rate eliminates flash by raising material viscosity, it also increases cycle time and still doesn't address the original cause of flashing. Worse yet, flash may reappear during the pack/hold phase.

What does a flash do?

What causes overpacking?

Overpacking occurs when extra material is compressed in one flow path while other flow paths are still filling.

What is flash and how is it removed?

Flash, also known as flashing, is excess material attached to a molded, forged, or cast product, which must usually be removed. This is typically caused by leakage of the material between the two surfaces of a mold (beginning along the parting line) or between the base material and the mold in the case of overmolding.

What is flash on a casting?

Flash or flashing is the material that is left on the casted part due to the 'seam' of the mould. The material enters into the seam of the mould slightly and when removed from the mould leaves a thin wafer of material attached. This is common and simple to remove with simple methods.
