Why Power Tech Machines
Engineered to raise output and cut metal loss.
Every machine we build is designed around one question: how does it make your casting floor more productive, more precise and more profitable?
Lower Metal Loss
Sealed vacuum-pressure chambers and controlled pour temperatures reduce oxidation and porosity, protecting every gram of gold and silver.
Repeatable Precision
Digital PID control holds temperature, vacuum and timing to the same set-point on every run — quality no longer depends on the operator.
The Machine Range
Seven platforms. One casting line.
From CAD CAM and 3D printing through wax injection, mould making, burnout and melting to the final vacuum pour — a complete jewellery manufacturing machinery line.

Talk to EngineeringThe Casting Process
One machine at every stage.
Power Tech equipment covers the full investment-casting workflow, so tolerances stay tight from the first mould to the finished cast tree.
STAGE 01
Design & Pattern
CAD CAM and 3D printing produce master patterns; the die press cures precise rubber moulds.
STAGE 02
Wax Injection
Automatic and digital wax injectors form clean, repeatable wax patterns for tree assembly.
STAGE 03
Burnout
The digital burnout furnace removes wax and cures investment with controlled ramp profiles.
STAGE 04
Melt & Cast
Induction melting feeds the vacuum casting machine for a dense, defect-free gold pour.
