Process
Wax Pattern Injection
Every job starts with a wax twin of your part, injection-moulded in a precision die. Even logos, serial numbers and tight undercuts are captured here - so accuracy is built in from step one.
Tree Assembly
Individual wax patterns are joined to a central feed runner to form a 'tree'. Casting a full tree at once means faster throughput and consistent quality across every piece.
Ceramic Shell Coating
The tree is dipped in fine ceramic slurry and dusted with refractory stucco -repeated several times - until a hard, heat-proof shell forms around every surface.
Wax Burnout (Dewaxing)
The shell goes into an autoclave where the wax melts and drains completely, leaving a hollow ceramic mould that's an exact negative of your part - the true 'lost-wax' stage.
Precision Pour
Metal is melted and poured into the preheated shell under controlled conditions. The hot mould lets the alloy flow into the finest details, giving a dense, defect-free casting.
Knockout & Finishing
The ceramic is broken away, parts are cut from the tree, then ground, heat-treated and dimensionally inspected - ready for machining or direct dispatch to your facility.
Why Engineers Choose
Investment Casting
Precision & Fine Detail
Hold tolerances down to ±0.1 mm with a smooth Ra 1.6–3.2 µm as-cast finish — intricate features captured straight from the mould, with minimal machining.
Complex Shapes, One Piece
Thin walls (~1.5 mm), internal passages and undercuts are cast as a single component — and multiple parts can be consolidated into one strong, lighter casting.
Wide Material Range, Near-Net Shape
Cast almost any alloy - stainless, carbon & alloy steel, bronze, aluminium - close to final dimensions, cutting material waste, machining time and cost per part.
