A group of connected curves that form a complete boundary of a surface.
Industry:Software
A group of connected surfaces that form an open shell.

A manifold edge is a mesh edge that has two entities attached to it. An edge is a line segment that connects two mesh nodes. In a Fusion mesh, manifold edges are the only type of edges which are correct. All other types should be corrected. A = free edges B = manifold edge C = non-manifold edge See also free edge and non-manifold edge.

A masterbatch is a concentration of filler or additives in a polymer. The mixture is added in small amounts to create the desired mix.
Industry:Software
A mathematical description of the relationships of the physical entity being described. For example, a geometry model is a mathematical description of the physical shape and characteristics of the part. Other models include viscosity model, process model, etc.

A meld line is a weakness or visible flaw created when two or more flows meet and converge while filling a part. A meld line is typically formed by parallel flows, whereas weld lines are formed by flows meeting at higher angles, often head-on. Meld lines tend to be less weak than weld lines. The quality of the meld line is dependent on the material type, the type and amount of fillers, and the pressure and temperature at the meld line.

A mesh consisting of surface (double-skin) shell elements. Surface mesh elements can be 3 or 6 noded planar, straight-edged triangles. A surface mesh analysis simulates the flow of the melt on both the top and bottom parts of the mold cavity. Consistency between the results on the opposite sides is maintained by using “connectors” - elements with zero flow and heat resistance. The connectors are inserted automatically at locations determined by the geometric features of the model. A surface mesh can include Midplane areas.
Industry:Software
A non-manifold edge is a mesh edge with more than two entities attached to it. An edge is a line segment that connects two mesh nodes. On a Fusion mesh, non-manifold edges should be corrected because they indicate elements which have not been correctly attached. A = free edges B = manifold edge C = non-manifold edge. See also free edge and manifold edge.

A pinpoint gate is a small gate, generally 0.75mm or less in diameter. In multi-cavity molds, the dimensions of pinpoint gates must be held within very tight tolerances in order to fill all cavities at the same time. The advantage of such a small gate is that it leaves a small, easily-removed mark on the part. Disadvantages include the following: *The melt tends to freeze early in a pinpoint gate, as the flow slows. For this reason its use is limited to small parts and to resins with good fluidity. *Pinpoint gates often require a third plate (for part removal), increasing mold expense. *Pinpoints gates can lead to very high shear rate and high entrance pressure loss. An indirect gate is a variant of a pinpoint gate. Indirect gates are used when the injection location must be transferred from center of part.

A planar space defined by a consistent set of curves. The curves connect but must not intersect.
