Custom OEM/ODM train-component requests include sand casting and combination-investment directions. Casting-steel and cast-iron requests require the actual supplied material and route to be selected, with high precision as a qualitative direction and color to customer request.
Train component, material and combination route
Identify the actual supplied specification and component drawing before assigning casting work. Confirm the intended meaning and stages of the combination-casting request, then define the controlled dimensions and measurement criteria for the chosen geometry.
Color and train-duty acceptance
Agree the requested color and actual finished condition around the component's interfaces and working requirements. Define dimensional, material, surface and functional acceptance, including any application-specific approval needed for the actual train component.
ISO9001:2015 and OEM/ODM responsibility
ISO9001:2015 is a quality-system reference whose applicable current document, responsible organization/site and scope need confirmation where required. Establish actual inspection criteria, methods and records against the supplied material, drawing and finished condition. Agree quantity and OEM/ODM responsibilities for the accepted component and casting route.
