01 · Shell Moulding

Shell Moulded
Precision.

In-house resin-coated sand plant. Heated metal patterns. Shells that hold tolerances conventional foundries cannot match. Surface finish that your machinists will thank you for. Parts from 500 grams to 150 kilograms are made in our foundry.

Shell moulding is a precision casting process widely preferred for components requiring superior surface finish, dimensional consistency, and repeatability — compared to conventional green sand moulding.

Superior surface finish
Better dimensional accuracy
Reduced machining requirements
Excellent repeatability for OEM production
Suitable for complex and precision components

02 · No-Bake Casting

No-Bake
Strength.

When your casting weighs 50 kilograms — or 500 — our No-Bake line takes over. Structural components. Complex internal geometries. Heavy-walled housings. The same standard. A bigger scale.

No-bake casting is preferred for medium to large-sized castings where strength, flexibility, and dimensional stability are essential.

Ideal for large and heavy castings
Better dimensional stability
Flexible for complex geometries
Improved mould strength and casting quality
Suitable for customised industrial components

03 · In-House Machining

In-House
Machining.

HMC. VMC. CNC Lathe. On-site. Your casting doesn't leave our facility until it's machined, dimensionally verified, and ready for your assembly line — cast, machined, and inspected under one roof.

HMC VMC CNC Lathe ISO 9001:2015

04 · Export Quality

Export-Ready
Quality.

ASTM A802. JDM B15. JDT 17015. ISO 9001. We speak the language of international quality standards — because our customers demand it, and because we've earned it.

The Process

Some things don't
photograph.

1450°C doesn't fit in a picture. Neither does the sound of a pour, the heat coming off a shakeout at three metres, or the moment a shell breaks away clean. We could show you a process gallery. We'd rather hand you the safety glasses.
