Take the Guesswork Out of Plastic Injection Molding Warpage

March 15, 2017

Plastic injection mold manufacturers have a nemesis when it comes to resolving warpage.  The culprit is the gap between the conventional assumptions, i.e. guesswork,  of mold temperature warpage and actual warpage of parts that occur in real time.

Because of advances in software technology, including software simulation packages, trial and error experiments at the production phase can be eliminated.  By using virtual simulation calculations, warpage theories are replaced by the virtual simulation scenarios at the design phase.  The key difference between experimenting at the production line and the virtual time is that temperature variations are taken into consideration during the entire mold design process.  More precise calculations can reveal necessary changes to prevent warpage during the actual production of plastic injection molding products.

Plastic Injection Molding companies are pressured at the manufacturing stage to deliver the best product available to the market within a quick turn around time.  Production budgets are strained by constantly retooling equipment in an attempt to find the precise temperature required to minimize warpage.  By recalculating temperature effects on molds at the design phase, computer model mimicking mold simulators reduce overall costs–resulting in increased realized profits for the manufacturer and a lower wholesale cost to the buyer.
