CAM

The appearance of this surface defect is similar to the grooves on a record. Record grooves are formed when a high flow resistance exists in the mold, thus leading to a repeated temporary stagnation ...

End of fill

Software; CAM

The end of fill occurs when the polymer has reached the extremities of the mould cavity and the mould is volumetrically filled.

Fan gate

Software; CAM

The fan gate is the opening between the mould runner and the mould cavity which has the shape of a fan. This shape helps reduce stress concentrations in the gate area by spreading the opening over a ...

Finger gate

Software; CAM

The finger gate is used when presentation is important and you want to avoid disfiguring the top face of a part. It tunnels down from the parting plane and comes up on the underside of the part. This ...

Valve gate

Software; CAM

A valve gate is a component of a hot runner system. The sprues from the hot runner drop through the cavity plate to the part(s). Each sprue has a rod that can be moved forward to cut off flow through ...

Vent

Software; CAM

A vent is a small channel at the end of a flow path that allows air to escape the cavity.

Weld line

Software; CAM

A weld line is a weakness or visible flaw created when two or more flow paths meet during the filling process. If the two flow fronts have cooled before meeting they don't interdiffuse well and can ...
