Cavity balance for plastic injection molding

Polymer Engineering & Science, 2000
AbstractCavity balancing is the process of altering the flow front within a cavity through thickness and design changes such that a desired fill pattern is achieved. This paper reports the preliminary research undertaken in developing an automated method for cavity balancing of two‐dimensional cavities. The aim of the automated cavity balancing routine

Optimizing flow in plastic injection molding

Journal of Materials Processing Technology, 1997
The mold and part design of plastic parts for injection molding is a complicated process, considerations for producing a part ranging from cost and speed of production to structural, ergonomics and aesthetic requirements. One of the routines faced by a designer when designing quality into a part is the process of cavity balancing.

Injection molding of plastic optics: the basics

Proceedings of SPIE, 1995
BASICSA. N. "STRETCHT' HOFFU. S. PRECISION LENSMATERIALSWe primarily use three materials in our molding of plasticlenses: acrylic (PNMA), polycarbonate, and polystyrene.Acrylic is the most desirable.-it is the most widely used—the refractive index is 1.491-it is the hardest,most scratch resistant-it has the greatest transparency, preferred for ...
