Friction-seat enquiries need the contact and mounting geometry defined alongside the material. This OEM/ODM stainless-steel component is listed at 40 × 30 × 20 mm, with precision lost-wax investment casting, CNC machining and sandblasting in the enquiry scope. Petrochemical machinery and engine uses are identified application areas.
Match the seat dimensions to the actual assembly
Use the dimensional reference to identify the requested part, then provide the drawing that controls the mating geometry. Mark the surfaces that locate the seat and any contact areas requiring finished dimensions. Describe the intended duty so the material and inspection requirements can be addressed for that assembly.
- Provide the friction-seat drawing and controlled revision.
- Select the stainless-steel grade and applicable specification.
- Identify machined interfaces and their dimensional limits.
- State quantity, surface requirements and inspection acceptance.
Define the investment-cast and machined scope
Lost-wax investment casting is the stated casting route, with CNC machining included in the enquiry. Distinguish the cast shape from the interfaces that require finished machining. Sandblasting is the named surface treatment, so identify any contact surfaces that need particular finishing instructions and the condition required on receipt.
Select documents for the intended machinery use
GB, ASTM, AISI, DIN and BS are named standard families. Specify the applicable material document and grade, together with any inspection requirements for the petrochemical or engine-component application. ISO9001:2015 is the stated qualification reference to address through relevant supplier documentation. A component drawing and acceptance basis establish the ordered seat more precisely than an application label or a dimensional reference alone.
