Gravity Die Casting
Maybrey's gravity die casting facility produces aluminium castings to 25 kg with a superior surface finish and improved mechanical properties compared to sand casting. We serve aerospace, commercial, buildings products, and general engineering customers, operating across a range that spans from mid to higher volumes.
Why Gravity Die?
Surface finish
The permanent steel die produces a smoother surface than sand, reducing finishing time and cost.
Mechanical properties
Faster solidification rates produce a finer grain structure and improved tensile strength.
Dimensional consistency
Permanent tooling delivers repeatable accuracy across a production run.
Versatility
Suitable for commercial grades through to class one aerospace aluminium alloys.
Materials & Capacity
Materials
Aluminium alloys, from commercial grades to aerospace-specification class one alloys. Specific grades confirmed at quotation. LM25, LM6, 2L99, LM27 frequently poured.
Weight range
Up to 25 kg per casting
Volume
Mid to high volume production
Tooling
Dies designed and produced in-house by our tooling team, with larger tooling sub-contracted to a trusted partner we have worked with for over 30 years. All maintenance carried out in house.
Aerospace Die Casting
Our die casting facility is certified to AS9100 Rev D and has held unbroken aerospace approval since 1936. We supply aluminium gravity die castings in the full range of aerospace alloys, many of which are machined in our facility before delivery. Our inspection department is equipped with the latest spectrometers.
In-House Tooling
All new dies are designed in-house. We produce a casting drawing detailing draft tapers, corner radii, machining allowances, and any modifications that benefit both the customer and the foundry. Our iron sand foundry casts all die blocks in-house, allowing us to control material quality and speed up delivery on new tooling.
