Gravity Die Casting : Aluminium & Zinc

Gravity Die Casting employs cast iron moulds which allow aluminium & zinc castings to be produced more accurately and cheaply than with sand casting. Tooling costs of gravity casting are a fraction of those needed for pressure die casting. The rapid chilling gives excellent mechanical properties whilst non-turbulent filling ensures production of heat treatable gravity castings with minimal porosity.

MRT have a range of microprocessor controlled hydraulic gravity die casting machines, which mechanise movements of the die, increasing production rates, and improving consistency. The machines offer tilt pouring, and hydraulic movement on up to four axes. MRT also have facilities for producing sand cores to cast complex internal shapes.

Heat Treatment
MRT supplies castings to all standard heat treatment specifications.

Non-Destructive Testing.
For critical components, MRT can provide X-ray, dye penetrant and pressure testing.

Process Control
Comprehensive set-up records and quality data ensure consistent production and reduce set-up time of the gravity casting.

Quality
Quality is achieved by pride in workmanship, backed up by an excellent quality system to ISO9001:2000. Everyone at MRT is committed to quality.

In-House Toolroom
Routine tool maintenance, breakdowns and modifications can all be undertaken in-house to reduce tool down time.

Tool and Casting Design
Our expertise can help you optimise designs, eliminating elements which add unnecessary costs to your gravity die casting. Thus we provide the benefits of automated production of aluminium or zinc die casting without high-cost tooling.
