Engine Components FAQ
What engine components can you manufacture?
We manufacture engine blocks and heads, pistons and connecting rods, crankshafts and camshafts, valve train components, timing gears and sprockets, and custom engine hardware. Our expertise covers automotive, aerospace, marine, and motorsport applications.
What materials are best for high-performance engines?
Aluminium 6061-T6 and 7075-T6 are used for lightweight engine blocks and heads. Steel 4140 and 4340 are ideal for crankshafts and high-stress components. Titanium is used for racing and aerospace engines where weight is critical. Cast iron provides durability for production engines.
What tolerances can you hold on engine bores?
Engine bores are held to ±0.01mm with precision honing. Piston-to-bore clearances are maintained within tight limits (typically 0.025-0.05mm). Cross-hatch patterns are applied for optimal ring sealing.
What is the typical lead time for engine components?
Simple engine components: 2–3 weeks. Medium complexity: 3–4 weeks. Complex assemblies (blocks, heads): 4–6 weeks. Racing and prototype components may require longer lead times.
Can you manufacture prototype and racing engine parts?
Yes. We specialize in prototype and racing engine components. Our capabilities include porting and polishing of cylinder heads, balancing crankshafts, and manufacturing custom pistons and connecting rods for high-performance applications.
Do you offer honing and finishing for cylinder bores?
Yes. We offer precision honing to Ra 0.4-0.8µm, cross-hatch pattern finishing, and boring. Bore concentricity and straightness are maintained within tight tolerances for optimal piston fit and ring sealing.
