At Atlantis Engineering, we follow a meticulous and controlled investment casting process to ensure precision, performance, and reliability in every component we manufacture.
Tooling &
Design
Dies (patterns/tools) are developed
using the latest CAD/CAM technology, ensuring
dimensional accuracy and consistency. We also provide
technical support to help customers create
cost-effective and optimized product designs.
Wax Pattern
Creation
Wax patterns are injected using
high-quality dies. Each wax pattern is 100%
dimensionally inspected before proceeding to the next
stage.
Shell Building
(Ceramic Coating)
Wax trees
(clusters) are coated with ceramic in temperature and
humidity-controlled environments, delivering excellent
surface finish and dimensional accuracy.
Dewaxing
Wax is removed
through a de-waxing process by placing ceramic moulds in
a hot wax bath, leaving a clean cavity for metal
pouring.
Shell Firing & Metal
Pouring
The ceramic moulds are fired at
900°C to 1150°C based on casting geometry and size.
Molten metal is then poured into the heated moulds.
Knockout &
Finishing
After solidification, castings
undergo fettling and finishing including gate cutting,
grinding, sand/shot blasting, leaching, and deburring.
Heat
Treatment
Castings are heat-treated as per
material specifications. Heat treatment cycles are fully
recorded and documented. Our furnaces are calibrated and
certified by Lloyd’s Register of Shipping.
Surface Finishing
Options
We offer a variety of finishes
including passivation, electro-polishing, blackening,
powder coating, glass bead blasting, and shot blasting,
tailored to customer specifications.
