Surface finish and integrity are two different facets of the cavity quality, but both play an important part in the characteristics of the mold. Much as the machine parameters affect the integrity of the sub-layers of the cavity, they also affect the surface finish. […]
While automation and accuracy technologies have made and are continuing to make significant progress, some of today’s most impressive innovations are taking place in the realm of spark generation and control. Tremendous strides have been made in improving the energy efficiency of diesinking EDM technology. […]
Many moldmakers have discovered that remaining profitable requires. As a result, automation has become increasingly important to the industry. A majority of moldmakers now implement some form of automation to maximize productivity, […]
Because filters play such an important role in optimizing wire EDM, it is important to use a reliable product. Not only do filters need to be the correct physical size and media size, they must be properly constructed to handle the large amounts of sludge that is generated and to keep the EDM particles from [...]
New manufacturing requirements are forcing CAM companies to take a closer look at their software development processes and sales distribution networks in order to deliver their products and software support to all countries where manufacturing plants are located. Traditionally, […]
Five-axis manufacturing techniques have long been used in the aerospace and power generation fields. This may be due to component geometry as found in gas turbine engines or automotive turbochargers, or complex and critical components such as landing gear on an aircraft. Or it may be an artifact of new computer-aided designs that use monolithic [...]
Most of the five-axis “magic” is managed by software in the CNC control and CAM software systems. The machine tool should be selected for sizes, speeds and capacities. And five-axis machine costs are coming down, and quality is improving with the implementation of CAD and simulation in the design process. […]
For those customers who refuse to pay for Moldflow analysis, First-rate Mold engineers and its customers mutually agree upon gate locations.if the gate location is not accurate, First-rate Mold more often than not absorbs the costs to rework the gating. That situation alone makes me more of a Moldflow advocate, […]
Runner sizing is a very important decision for a moldmaker. In hot runners, the moldmaker may seek to minimize the runner diameters in order to reduce melt residence time, reduce color change cycles or allow tighter pitch for drops. In cold runner molds, smaller runners mean lower material wastage. However, smaller runners in hot and [...]
A common challenge faced by moldmakers is to produce acceptable parts with minimum cycle time. As cooling time accounts for most of the cycle time, reducing the cooling time of a part will considerably reduce the cycle time. However, reducing the cooling time also may result in problems, such as excessive part warpage, high part [...]
