China industry spends hundreds of billions a year in costs related to, or caused from, corrosion. In the plastic’s industry, these costs are not limited to mold damage and repair. Corrosion also causes the breakdown/shutdown of a press, leading to manufacturing downtime and significant loss of productivity. […]
Today’s competitive manufacturing environment demands ever increasing productivity, efficiency and quality. While manufacturers have tended to be quick to look to automation to improve their manufacturing processes, improving yields, reducing waste and shortening production cycles, they’ve not always thought of the importance of automation to improve their business or human resources processes. Yet automation can [...]
Copper is the most thermally conductive of the common solids; only silver, cubic boron nitride and diamond are more conductive. This makes copper an excellent choice for plastic injection molds that must remove heat from the injected, molten plastic to make it solidify. However, copper is neither hard nor strong enough in its pure form [...]
The success of a mold manufacturer boils down to its ability to deliver high quality products at the shortest possible time and the lowest possible cost. Following are some mold design best practices that will help you achieve these goals. […]
Unlike traditional feature-based modeling, which relies on a sequence of operations to construct designs, direct modeling works on what has previously been called dumb geometry, using feature recognition and other technology to allow direct manipulation of previously frozen solids. Direct modelers offer a simpler modeling paradigm that can allow fast creation and editing, removing a [...]
Die sinking EDM works wonders in cutting contours or cavities in pre-hardened steel. When dealing with complex shapes, however, milling the electrodes that produce these intricate pieces can be a quite involved and time-consuming process, so manufacturers want to extend electrode life as much as possible. […]
Siemens PLM Software (Plano, TX) a business unit of the Siemens Industry Automation Division and a leading global provider of product lifecycle management (PLM) software and services, has released NX™, the company’s fully integrated computer-aided design, manufacturing and engineering analysis (CAD/CAM/CAE) solution. NX 8 includes extensive enhancements to its CAE offering–including its widely used NX [...]
When considering ways to reduce mold setup and improve part removal a moldmaker should explore the benefits for both the moldmaker and the molder by considering the following five technology solutions: […]
One of the greatest challenges facing moldmakers today is reducing production costs while still maintaining high levels of precision. Moldmakers have frequently relied on one of two technologies to help them accomplish this: […]
There are many reasons why molds and dies need to be welded—they get cracked, chipped or broken. However, most of the time it is because of engineering changes that have been made late in the product development process where repairing the mold is less expensive than manufacturing a new one. […]
