Ventilated grey-iron brake-disc rotor enquiries are offered for heavy-duty trucks and construction machinery through a custom sand-casting scope. Start with the actual rotor drawing and application so that the material, ventilation geometry and mounting interfaces can be evaluated together.
Identify the rotor and its mating assembly
Provide the vehicle or machinery reference, drawing revision and required quantity. Show the disc envelope, ventilation passages, mounting pattern and hub relationship. These details help distinguish the requested rotor from another component with a similar appearance or overall diameter.
Select the material and acceptance standard
GB, ASTM, AISI, DIN and BS are named standard families, so specify the complete applicable material designation and acceptance requirements. Specify the complete rotor material grade for its required braking duty. Aluminum and steel are additional component-material enquiries that should be scoped separately from this grey-iron brake disc.
- Mark the mounting and braking-interface dimensions on the drawing.
- Define the required grey-iron grade and governing standard.
- Identify ventilation geometry and dimensional acceptance limits.
- Specify braking-service tests and application approvals required.
- Provide the quantity and delivered-condition requirements.
Make inspection relevant to the selected rotor
The stated quality-control scope is 100% inspection. Agree the measurements and applicable braking-service acceptance for the ordered configuration, then connect the inspection record to the approved drawing and material reference. Wooden-case packing is listed for the component, and relevant current ISO9001:2015 qualification documentation can be requested within its actual supplier and process scope.
