Finding new ways to ensure superior mold performance is a goal most people share. The technologies that are available are impressive, and more are becoming available every day. One of the latest is x-ray spectrometry, and it can help take the guesswork out of surface treatment. […]
Performance requirements for hot runners are becoming more demanding as technology advances and applications grow in complexity. Increased resin pricing and the need for automation are making direct gating of even the smallest parts a necessity. Customers expect good quality parts from every cavity—where the hot runner plays a key role in delivering the melt [...]
Many of you have probably heard of self-venting or gas permeable mold steel, but are not totally familiar with it. Gas permeable mold steel is a sintered, pre-hardened to 35 HRc material with porosity in the range of 20 to 30 percent by volume. A system of interconnected micron-sized pores is dispersed throughout the material. [...]
During the concept phase of a new project the option of selecting a stack mold is often overlooked because many mold designers are unfamiliar with the technology. Compared to a regular, single-face injection mold, stack molds can virtually double the output of an injection molding machine by distributing the plastic melt into two separate mold [...]
A purchase order has been promised by the customer for weeks, and finally the green light has been given to the mold design team. No sooner has the design started and the shop foreman is asking when steel can be ordered, […]
Most moldmakers are already familiar with using surface modeling techniques to undertake minor modifications to product designs—such as adjusting draft angles or increasing fillet radii to ease the flow of material—and to create extra geometry for the core and cavity, such as split surfaces. […]
Some CAM vendors refer to optimized software as the software best suited for the types of machines, processes or parts being programmed. On one hand, having CAM integrated with the CAD program may be argued as the most effective and optimum way to work. Conversely, CAM programmers may be better served by selecting specialized software [...]
Data translation between CAD and CAM software applications is very high on the list of problems for buyers. The standard format IGES and the popular VDA in Europe are often flavored by software developers to fit their database structures. […]
With tribrid modeling, there is no need to convert the triangles into surfaces or solids. Furthermore, having all three modeling techniques in a single package reduces the need to transfer data between multiple programs and so streamlines the whole product development process. It means that moldmakers can move data captured with reverse engineering into the [...]
While the Internet may hold intriguing possibilities for the future, moldmakers need helpful, online options today. Fortunately, there are several sites that – if used correctly – can help moldmakers become more profitable. […]
