Moldflow develops plastic injection molding software.
Clamp force is the force required to hold the mold 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 molding cylinder.
Industry:Software
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 mold boundary.
See also Free Edges.
Industry:Software
The period during the injection molding 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
Control limits are statistically determined values between which a control variable is allowed to range without adjusting the process. Control limits provide an indication of the variation in the injection molding process.
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.
Industry:Software
A cooling channel is a passageway in a mold for circulating water or another cooling medium, in order to control the temperature of the metal surfaces in contact with the plastic being molded.
Cooling channels are typically connected to form a circuit. Cooling channel configurations can be serial or parallel.
Industry:Software
Gross cooling time is the time after the velocity phase until the part is sufficiently cooled to be ejected from the mold. Therefore, gross cooling time is the sum of the pressure phase (packing and holding) and the net cooling time
The net cooling time is the time after the pressure phase and before the part is ejected from the mold.
