Have you found any good EDM operators lately? If so, count yourself lucky. If not, you probably know that you are not alone. The current scarcity of skilled labor facing the manufacturing industry is unprecedented. Even if you are fortunate enough to have a skilled EDM operator, what happens when that person gets sick or [...]
When it comes to molding very small threaded plastic parts, including those with undercuts or straight walls, size does matter—but not as much as it used to. […]
When it comes to injection molds, the importance of an efficient cooling system cannot be overemphasized. A reduction of just one or two seconds in cooling time can lead to as much as a 10- to 20-percent increase in the production rate. That alone could directly affect the profitability of the job. However, saving time [...]
The moldmaking industry is often at the cutting edge of metalworking technology. Innovations in machine tool design, cutting tools and CNC programming are typically championed by moldmakers in their quest for increasingly precise tools. Highly accurate measurement tools are also becoming necessary for mold design and manufacturing, though the industry has been slower to adopt [...]
With manufacturers putting increased pressure on their suppliers for cost savings and efficiencies, mold manufacturers are being challenged to produce consistent, accurate product cost quotes. These challenges include the need for: […]
There has been a long-standing, unresolved debate over whether graphite or copper is a better EDM electrode material. The preference is most always the same in any one geographical region. In North America , the preferred electrode material has shifted from copper to graphite. In Europe and Asia, many argue that copper is the preferable [...]
The use of CAE for injection molding simulation has progressed from flow-front prediction in the late ‘70s to full simulation of the injection molding process, its variants and associated processes. Injection molding simulation benchmarking is the comparison of predicted and actual process parameters. Typically, an extensive study is carried out on a mold, machine and [...]
Use of aluminum tooling has been an ongoing discussion for years, and the resulting flow of information has been a key part of aluminum’s growth as a mold material alternative. This continuous growth has led to advances in mold alloys, material size availability, mold design, finishing practices, coatings and welding techniques. More and more success [...]
In moldmaking, manufacturers are constantly searching for ways to increase productivity by cutting production time and costs. Today, a hybrid process exists that allows additive machining and milling in the same setup to address those two challenges. […]
Mold building in China is a very challenging business. Two of the difficulties are offshore competition and molders’ growing demands for early design involvement. One solution to combat these challenges is mold filling simulation. Its use can help mold builders stay competitive, enhance efficiencies, meet customer expectations and create more business opportunities. Following are four [...]
