Vacuum Controller for Better Die Casting

A major cause of scrap in die casting is porosity. Porosity in castings can be minimized by the use of an effective vacuum system. Frequently less clamping force is required when vacuum is used, and larger and thinner castings can be made by smaller machines.

Some die casters believe that venting alone is adequate, and vacuum is unnecessary. The reality is that with the level of quality now being demanded in today's market, to remain competitive the use of vacuum is usually essential.

Die casters often use vacuum systems that are no longer adequate for the degree of quality required. They may be unaware of the level of performance that is now possible from a contemporary vacuum system. In the past few years the average performance has improved considerably. For example, valve preventive maintenance is now often not required until after at least 25,000 shots.
