Vacuum Die Casting
When excessive air is trapped inside the casting it will cause defects such as internal porosity or blisters on the surface. If normal venting is not sufficient, you can extract it out using vacuum.
This is a totally modular system which can be scaled to suit any application. Start off with a simple low-cost system to get going quickly and prove out the process. Add extra functionality and sophistication at any time as needed.
Vacuum Control Module
This compact, rugged device is mounted near the machine and is the heart of the system.
The top pipe is connected to the die with a rubber vacuum hose. The bottom pipe is connected to the vacuum supply with another rubber hose.
At the correct time, the rugged, sludge-resistant valve switches on the vacuum to the die, removing the air from the cavity. On the front is a special vacuum filter which traps any metal flakes which may emanate from the die.
For a simple, low-cost vacuum system, the Module can be connected directly to the control cabinet of the die casting machine.
Vacuum Source
This system will work with any vacuum source, from a single pump for a small hot chamber die to a large central vacuum system with multiple pumps, tanks and piping systems.

Vacuum Vents
This system will function with a wide range of vacuum vents in the die including:
- Chill Vent Inserts
- Zig-zag vents
- Normal straight-path vents
CASTVac® Vents
This is a new type of vacuum vent, designed for use in very large cold chamber dies and which has some of the characteristics of both chill vents and mechanical valves. It has venting faces which are nearly perpendicular to the die parting plane and some unique benefits including:
- Large venting area
- Very compact
- Controlled uniform venting gap
- More efficient than standard chill vents
- More reliable than mechanical valves
Die-Shot Connection
For extra functionality, the Vacuum Control Module can be connected to a Die-Shot Advanced Shot Monitor. This enables a Duct Cleaning function to apply a small amount of compressed air to the ducts to keep them free of metal flakes. It also enables measurement and monitoring of the vacuum levels, saving of all parameters and much more.
