How Integrated Vacuum Assist Improves Die Casting Quality and Process Control

ELK GROVE VILLAGE, IL, June 23, 2022 -

The power the vacuum system provides in die casting offers a clear advantage in providing suction and creating a higher quality part. 

Shibaura Machine's vacuum assist offers the ability to remove air, steam, and other gases effectively from the cold chamber and cavity as the shot begins. This allows for a more effective way to produce a high-quality casting than simply hoping these gases will sweep themselves out through the vents on their own. 

But what about taking it one step further and integrating the vacuum with the machine? 

How Basic Vacuum Systems Works

First, a brief background of the technology for the vacuum assist is required. Vacuum systems in die casting have been used for decades and the process is fairly straightforward. Using a vacuum-assisted system, the vacuum is used on both the sleeve and mold cavity before the injection shot occurs. This allows almost all air to be removed from the mold, decisively reducing gas porosity in the casting. 

While the significant reduction in the volume of gas porosity and the pore sizes in castings improve the density and tensile strength of the end product, even further advantages can be gained with an integrated vacuum assist system.

Integrating The Vacuum System

Like many applications in die casting, vacuum systems have long been added to numerous other individual pieces surrounding the base of the machine. Sound familiar? This means yet another machine to track, control, measure, and maintain. Therefore, the process of vacuuming alone will not make a casting system more efficient. The true advantage lies in the ability to have a fully integrated vacuum assist system with your die casting machine.

Being able to seamlessly integrate your vacuum assist at the factory with your die casting machine allows you to further increase process transparency and control, meaning better uptime and part quality. Shibaura Machine’s DVF200C system is seamlessly integrated into your Shibaura Machine die casting machine with the vacuum pump, reservoir tank, and valves sized to meet the expected need. 

This integration allows for the operation and application to happen as part of the total machine control, not just another device sitting nearby. This also allows for increased process transparency with all vacuum parameters measured, monitored, and reported through the TOSCAST control system.
