There are four major steps in the die casting process. First, the mold is sprayed with lubricant and closed. The lubricant both helps control the temperature of the die and it also assists in the removal of the casting. Molten metal is then shot into the die under high pressure; between 10—175 MPa (1,500—25,000 psi). [...]
Die casting is the process of forcing molten metal under high pressure into mold cavities (which are machined into dies). Most die castings are made from non-ferrous metals, specifically zinc, copper, aluminium, magnesium, lead, and tin based alloys, although ferrous metal die castings are possible. […]
To find the best process you must find the bottlenecks and move them to the beginning of the process. Now finding all the bottlenecks and addressing them appropriately is a challenge, but the answer is so simple: standardize all processes. […]
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. […]
