Die casting is a manufacturing process that uses high pressures to force molten metal from a crucible into a metal jacket. The material is then injected through a rod into a preformed mold (die). Once injected, the part is cooled, solidified and removed from the mold. This process is used for both parts and ingots. [...]
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 [...]
Perhaps one of the more interesting markets we’ve seen in moldmaking in recent years is applying North American quality to overseas molds. In other words, shops are finding that making poorly made molds work properly, even having to re-machine features or whole molds, is an area of growth potential. […]
Among shops that suffer from techno-phobia, many jump into EDM work believing, “I just have to have the machine, and my guys can change these electrodes in and out.” This mindset usually results in a lot of downtime for machines. […]
