Precision Aluminium Gravity Die Casting Solutions
Our gravity die casting operations support components ranging from 0.10 g to 50 kg, allowing the production of both small precision parts and large structural castings. With maximum casting dimensions of 1600 × 1200 mm, Ozbros provides flexible manufacturing capabilities suitable for a wide range of engineering applications.
By combining advanced casting technology with automated handling systems, robotic operations and integrated downstream processing, we ensure reliable production, consistent quality and efficient manufacturing performance.
Advanced Gravity Die Casting Process
Gravity die casting is a well-established aluminium casting method used to produce high-strength aluminium components with excellent repeatability and durability. In this process, molten aluminium is poured into reusable metal moulds using gravity rather than external pressure.
This controlled casting process improves material integrity, reduces porosity and provides superior mechanical properties compared with many alternative casting methods. Gravity casting is particularly suitable for medium-to-high production volumes where consistent quality and dimensional precision are critical.
At Ozbros, our production lines utilise advanced tilt-pouring casting systems and automated robotic handling technologies, ensuring stable casting conditions and reliable production output.
