Closed-die forging
A heated billet takes the shape of the die under the hammer. The forging route is reviewed around your geometry, material and required machining allowance.

01 / FIELD NOTES
Three disciplines. One route.
The sequence is planned around the component. Heat treatment and finish machining are positioned to suit the required final condition.
OPERATION / 02
CNC & VMC machining
The forged blank moves toward its finished dimensions through the agreed machining operations. Bores, faces, profiles and connection features are defined by the approved drawing.

OPERATION / 03
Heat treatment & condition
When treatment is specified, its requirements are agreed with the manufacturing route. Specialist partners carry out heat treatment; the final condition and any related checks belong in the order specification.

02 / QUALITY THROUGH THE ROUTE
Five checkpoints.
One complete picture.
Material identity, manufacturing control and dimensional evidence all matter.
- 01
Raw material verification
Grade, heat number and incoming size are checked against the material certificate. The material identity establishes the starting point for the batch.
Review with us: material standard and certificate requirements. - 02
In-process inspection
Critical features are checked during machining, so dimensional control is part of production rather than a final-only activity.
Review with us: critical features, datums and inspection frequency. - 03
Dimensional inspection
Finished dimensions are measured against the drawing. A useful inspection plan identifies the features that matter most to fit and assembly.
Review with us: report format and drawing revision. - 04
Final quality check
Conforming parts are released against the agreed requirements. Final review brings together the component, its specified condition and the required documentation.
Review with us: acceptance criteria and release documents. - 05
Process monitoring
Production information is followed across the batch to support consistency. Lot identity connects the material and manufacturing stages.
Review with us: lot identification and traceability needs.
03 / TRY THE TOLERANCE
A small number.
A clear boundary.
Move the slider to explore an illustrative Ø65 mm bore with a ±0.05 mm tolerance. The reading changes from within limits to outside limits.
This is a demonstration, not an inspection result. Actual tolerances, measurement methods and acceptance criteria are agreed for each drawing.

- Sample quantity, batch size and expected repeat demand.
- Critical dimensions, inspection documents and delivery destination.
Q&A / FIELD NOTES
A few useful answers.
Is heat treatment carried out at GTF?
Forging and machining are carried out in our own shop. Heat treatment is coordinated through specialist partners. Dimensional inspection is in-house, with selected specialist tests arranged as required.
Can you work to a tighter tolerance?
Send the drawing with the critical features clearly identified. Geometry, material, condition and inspection method affect feasibility; the final scope is confirmed through technical review.
Which reports can be requested?
Discuss material certification, dimensional reports, hardness results and lot traceability when requesting a quotation. The report and testing scope are agreed before production.
