Grey-iron exhaust-manifold enquiries are offered through a custom sand-casting scope. Metal or plastic CNC prototypes, vacuum casting and injection-molding projects are separate service requests, with low-volume production and rapid tooling defined for the actual deliverable.
Give the manifold its own material and geometry
Provide the exhaust-manifold drawing, required iron grade and the connections used by the adjoining assembly. Specify the interfaces and service conditions that influence the design. Keep this casting brief distinct from a prototype or tooling request so the manufacturing proposal addresses the selected item.
Define prototype and low-volume projects separately
Additional metals include aluminum, brass, bronze, copper and steel. Select the material and CNC, vacuum-casting or injection-molding scope for each requested prototype. Equipment references include CMM, CNC milling/turning/lathe, wire cutter and RIM, with the relevant operations and acceptance checks to be agreed for the project.
- Identify the manifold, prototype or tooling deliverable.
- Specify the full material grade and required process.
- Provide geometry and critical mating dimensions.
- Define quantity, evaluation purpose and acceptance.
- Select color and the required surface condition.
Choose the finish for the selected material
Polishing, painting, anodizing, silkscreen, sandblasting and texture are named surface options. Identify their coverage and the result needed for appearance or function. Automotive, medical, digital and appliance-prototype projects can each provide their own requirements, keeping the component geometry, evaluation conditions and finished acceptance together in the enquiry.
