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, […]
The era of robotic automation’s reputation as an expensive, over complicated technology is gone. In recent years many small to medium-sized companies have turned to automation in order to compete with low-cost sourcing. […]
Recent advancements in industrial PC CNC controls have opened a new technology path to improved speed, accuracy, surface finish, flexibility and convenience for moldmaking, along with greater value. Here is a review of some of the features of the next generation controls you should consider when investigating your next PC CNC control purchase. [...]
