Moldflow develops plastic injection molding software.
Ejector pins are located on the mold and push the part out of the mold when the clamp is open.
Industry:Software
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 to avoid dark streaks.
Industry:Software
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 increasing mold wall temperature may help solve the problem.
Industry:Software
Usually occurs because of different orientation of the pigments in the flow, or poor blending in the plastication stage.
Industry:Software
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 on the opposite side from ribs or bosses because the additional thickness causes increased contraction.
Industry:Software
A feasible molding window is represented by a set of boundaries that define a window-like shape. For the process setting ranges inside the window boundaries, the molding process is feasible; outside the window boundaries, the molding process is not feasible.
Industry:Software
A fillet is a rounded interior corner of a part that makes the part stronger.
Industry:Software
A flash occurs when the polymer is not totally contained within the mold cavity. The most common causes of flash are an excessive velocity stroke, injection velocity, packing pressure, and a low clamp force.
Remove flash by either reducing the injection velocity or increasing the clamp force.
Industry:Software
A flow path is a route along which molten plastic moves within the cavity.
Industry:Software
A free edge is an element edge that is not shared by other elements. A free edge has an element attached to only one side. An edge is a line segment that connects two mesh nodes.
In Fusion and 3D meshes, free edges should be corrected because they indicate elements which have not been correctly attached. See also manifold edge and non-manifold edge.
