Quality assurance

Verification Before Batch Production

New products are trial produced first. Parts not made for a long period are re-verified on the first piece. Only then does the batch run start.

01

Sample development trial

Every new product goes through a sample trial. Batch production starts only after the sample meets all inspection requirements.

02

First article inspection

For products not produced for a long period, the first piece is fully inspected and confirmed acceptable before the batch run.

03

Simulation before pouring

MAGMA casting simulation, introduced in 2017, verifies riser feeding and supports casting soundness before production starts.

04

Unique traceability code

Each casting carries a unique tracking number that links all production records to that individual part.

Every casting carries a unique tracking number. Through that code, all production records can be linked back to the individual part.

Inspection & testing

In-House NDT and Mechanical Testing

We carry out the common non-destructive and mechanical tests on site, so results are available with the parts rather than after a third-party queue.

Magnetic Particle Inspection

Surface and near-surface crack detection

NDT

Ultrasonic Testing

Internal discontinuity detection

NDT

X-Ray Radiography

Internal shrinkage and porosity evaluation

NDT

Dye Penetrant Testing

Surface defect detection on finished faces

Mechanical

Tensile Testing

Yield and tensile strength verification

Mechanical

Impact Testing

Toughness verification at specified temperature
