Moldflow develops plastic injection molding software.
A point whose coordinates are the average of the coordinates of a given set of points and which for a given planar or three-dimensional figure (as a triangle or sphere) corresponds to the centre of mass.

A cheque ring is the sliding ring of the non-return valve on the front of the screw. The cheque ring allows melted plastic to flow forward to the front of the screw during plastication, and prevents flow back into the screw during injection. The cheque ring is a high wear item that can leak during injection, effectively reducing the pressure that is applied to the melted plastic.

A chiller is a self-contained system comprised of a refrigeration unit and a coolant circulation mechanism consisting of a reservoir and a pump. Chillers maintain optimal heat balance by constantly recirculating chilled cooling fluids to injection molds.

Clamp capacity is a measure of the largest projected area of cavities and runners that an injection moulding machine can safely hold closed at full moulding pressure.
Industry:Software
Clamp force is the force required to hold the mould closed while an opposing pressure is exerted by the plastic injected into the cavity.
Industry:Software
A closed loop controller is one that responds to feedback from transducers that measure the value being controlled. For example, cavity pressure can be controlled by placing a transducer in the cavity and using that measurement to adjust the pressure on the plastic in the injection moulding cylinder.

A closed volume is a group of surfaces connected together to form a polyhedron. A closed volume has no free edges. The structure is used to form inserts and the mould boundary.
See also Free Edges.
Industry:Software
The period during the injection moulding process when plastic is injected to compensate for the plastic in the cavity shrinking as it cools.
Industry:Software
A group of curves that are joined end to end to form a single curve. Composite curves are discontinuous if the start point of one curve is not the same as the end point of the previous curve.
IGES composite curves are:
*Composite Curve (IGES Type 102)
*Boundary Entity (IGES Type 141)
*Curve on a Parametric Surface (IGES Type 142)
Industry:Software
Heated plastics are compressible. The compressibility of a material affects the volume of plastic required to produce a finished part.
A compressibility model describes the relationships between pressure, temperature, and the volume (PVT) of the plastic material.
The compressibility model that the software uses is the 2-Domain Modified Tait PVT model with 13 coefficients.
