Pioneering Gravity Die Casting (Permanent Mold) and Sand Casting of certified aluminium alloys ranging from 100 grams to 350 kg.
Gravity Die Casting (GDC) utilizes precision-machined reusable steel dies made of Cast iron, SG Iron or high-grade alloy steel. Liquid molten aluminium is poured under gravity into the pre-heated steel mold, resulting in faster cooling rates, finer metallurgical grain structures, and superior mechanical properties.

For larger castings with low volume and complex cavities, Growell manufactures sand castings capable of pouring single components up to 350 kg..
Our foundry utilizes clean electric melting furnaces to prevent hydrogen absorption and gas porosity in molten aluminium.
Equipped with 200 kg bale-out electric furnaces and 250 kg tilting electric furnaces with digital PID temperature controllers maintaining accurate pour temperatures within ±5°C.
Every heat is treated with inert gas rotary degassing and eco-friendly fluxes to eliminate dissolved hydrogen gas and non-metallic inclusions.
After degassing every melt is checked for density index and pouring starts if the density index is in acceptable range. Thermo analysis is used to check grain refinement and modification at molten stage
In-house heat treatment furnace with rapid water quench tanks. Enables solution treatment and precipitation aging to achieve required strength and hardness.
