Is Wire Cut EDM (WEDM) Useful In Plastic Injection Mold Making?

When CNC WEDM, or wire EDM, first became available as a viable machine tool, somewhere around 1976, the buzz was that it would never be applicable for injection  moldmaking. The thinking was that mold cavities are blind, meaning that the shape is cut into the steel, not through it. Wire cut EDM and band saws Because the WEDM operates somewhat …

An Overview Of Surface Grinding In Injection Moldmaking

Precision surface grinding in plastic injection moldmaking is essential in order to produce high quality, high volume molds. Despite the fact that hard machining and WEDM have replaced grinding in many aspects, the need for accurate, detailed grinding remains. Consider that, from beginning to end, nearly every mold component must be ground. The list could include every plate in the …

Why Use Stainless Steel For Injection Molds

  The many unique values provided by stainless steel make it a powerful candidate in materials selection. Engineers, specifiers and designers often underestimate or overlook these values because of what is viewed as the higher initial cost of stainless steel. However, over the total life of a project, stainless is often the best value option.   Continue reading….
