Feiya's cylinder head manufacturing capabilities are based on mature aluminum die-casting systems, stable displacement platform development experience, and controllable CNC machining processes, and are suitable for long-term batch supply and platform-based structural parts projects. We emphasize batch consistency, structural integrity, and stable adaptability to the assembly requirements of the engine manufacturers.
· Stable displacement platform experience
· Controlled die casting and machining rhythm
· Reliable batch consistency
· Adapt to the structural requirements of multiple industries
Over the years, we have provided long-term and stable cylinder head OEM manufacturing services to many motorcycle brands (including listed companies), and have become the largest motorcycle cylinder head manufacturer in Yueqing City, China.
Feiya can mass-produce multiple platforms such as 125, 150, 250V, 300V, 450V, 500V4, 650V, 700, 800V, and 1000V, and can carry out customized development and trial production based on customer drawings.
The cycle depends on mold development, trial stability, and batch quantity. Normally, new projects take about 35–50 days from mold design to first sample delivery, and the mass production cycle is controllable according to the production schedule.
Most cylinder heads use aluminum alloys such as ADC12, A356, etc. Based on displacement, structure, and heat dissipation requirements, the material will undergo corresponding melting control and heat treatment.
It is mainly evaluated through size chain control, CMM inspection, airtightness testing, and key wall-thickness measurement. Feiya keeps batch records to help customers track changes and conduct long-term verification.
A motorcycle cylinder head is one of the most important structural parts of an engine. It houses the combustion chamber, valve mechanism, cooling system, and oil passages. It directly affects compression ratio, heat dissipation efficiency, and power output. It is typically produced by aluminum alloy die casting and finished by CNC machining for all key dimensions.
The usual manufacturing process includes: Molten aluminum melting and composition control → high-pressure or low-pressure die casting → burr removal → CNC machining of key dimensions (such as combustion chamber, sealing surface, screw hole) → heat treatment and aging → airtightness testing → final inspection and packaging. Mold structure, fixturing, position accuracy, and internal quality requirements are the main technical challenges.
