Basically, the function of an ejector sleeve in a mold is to eject either an entire finish molded piece part or apply ejection force to some portion of the molded piece part to assist with part ejection, in combination with other ejection features designed into the mold. […]
The equipment for producing machine-ready blanks efficiently may not be purchased off-the-shelf, including specialized Blanchard grinders, double-disc grinders and duplex mills. […]
Typically, mold manufacturers begin with raw stock sawed to rough dimensions. Before it can be finish machined into a mold component or a mold base, it should be machined to exacting tolerances on six sides. […]
Due to the intensive machining practices that must be performed on mold bases, if machining time and costs can be reduced, significant savings can be realized. […]
The new alloy uniquely fills the demands that many moldmakers have that are not being addressed today in our marketplace. First, this grade provides good polishability without having to be remelted. […]
The new plastic mold steel is typically supplied in the hardened-and-tempered condition at approximately 290 to 330 HB, corresponding to about 32 HRc. In this way, a good combination of machinability, hardness and wear resistance is given. […]
Prehardened 400 series stainless steel (DIN 1.2316) is generally used for calibration tools and mold inserts for the plastic processing industry. Today, plastic products are manufactured by mass production, […]
The use of relatively inexpensive yet specialized grit brushes or honing tools can be highly effective in improving the accuracy of mold assembly or enhancing injection molding productivity through more efficient cleanup of metal surfaces. […]
Besides sophisticated processes, strategies targeting niche markets and geographies also are leading to moldmaker growth. When asked to rate the impact 13 different factors will have on the future success of their business, moldmakers rated “adding niche capabilities” as the second most important factor, closely behind quality molds and quick delivery, which were tied for [...]
