Casting, heat treatment and finishing in one controlled chain
Mold-to-Machining Process Control
Mold design, core making, die casting, T6 heat treatment and CNC finishing run as one process chain, so a dimensional decision made at the mold stage holds through the final cut.
Critical dimensions measured and archived per batch
Batch-Documented Quality
Chamber volume, seat concentricity, guide bore and deck flatness are measured on each batch and archived, so a reorder seasons later matches the sample you approved.
Tooling built around your drawing, sample or order volume
Volume & Custom Flexibility
Tooling and processes adapt to your drawings, dimensions and engine requirements — from prototype and pilot batches to container-load repeat orders.
Our Production Process
Mold Design
Each program starts from your drawing or a sample. Engineers evaluate wall thickness, fin geometry and structural load before tooling is cut, because decisions made at the mold stage decide the dimensional consistency of the castings that follow.
Core Making
Automatic shell-core machines produce high-strength coated sand cores for the water jackets and oil passages inside a head. Core precision sets the airtightness and flow efficiency of the finished casting, so cores are gauged for dimension and surface before they enter the mold.
Die Casting & Heat Treatment
A356 aluminum is cast under high or low pressure to match the part's structure, then T6 heat-treated to bring the casting to full strength. Mold temperature, fill speed and pressure are logged per shift, and the parameters stay attached to the batch record.
CNC Machining & Inspection
Critical dimensions are finished on machining centers with dedicated fixtures: seats cut after pressing, guides honed, decks finished flat, cam journals line-bored. Chamber volumes and flow-critical profiles are verified per batch — the same discipline behind the platforms on our dirt bike cylinder heads page and the commuter volume on our commuter bike cylinder heads page.
Tooling & Mold Workshop
Precision machining and maintenance setup dedicated to mold fabrication, core box fitting, and tooling alignment. Rigid fixture bases and multi-axis drilling configurations maintain strict geometric repeatability, laying a flawless foundation for long-run casting integrity.
Core Making Workshop
Core making machines produce sand cores that form complex internal cavities and passages in cast components. Consistent core production helps maintain dimensional accuracy and supports reliable casting quality.
High-Pressure Die Casting Workshop
Multiple die-casting machines run a steady cycle rhythm for structural castings that demand density and dimensional stability. For complex component housings, temperature, pressure, and fill speed are controlled to keep shrinkage out of critical load paths — the difference between a casting that machines clean and one that scraps on the deck.
Low-Pressure Die Casting Workshop
Smooth, bottom-up molten metal feeding under precise pneumatic control reduces turbulence and oxide inclusion during filling. Ideal for heavy-wall and high-integrity aluminum structural parts requiring superior mechanical properties and leak-tight density.
Deburring & Trimming Station
Dedicated flash removal and manual deburring stations clear parting lines, gate stubs, and sharp edges immediately after casting. Workstations equipped with targeted dust extraction systems ensure consistent surface prep and safe, efficient workflow.
Shot Blasting Workshop
High-capacity automated shot blasting systems sweep away residual sand, surface scale, and micro-burrs. The process achieves a uniform, matte surface finish while relieving internal surface stress prior to downstream machining and coating.
Heat Treatment Facility
Vertical drop-bottom quenching and aging furnaces execute precise T5/T6 thermal cycles. Programmed ramp, soak, and rapid quench phases optimize grain structure, enhancing tensile strength, yield performance, and elongation across high-stress castings.
Surface Coating & Painting Line
Enclosed spray booths and batch racking systems apply protective primers and functional surface coatings. Designed to shield raw castings against corrosion and oxidation during storage, handling, and harsh operating environments.
CNC Machining Workshop
Multi-axis machining centers run high-precision milling, boring, and tapping operations in a clean, climate-controlled environment. Customized rigid clamping and optimized toolpaths guarantee tight tolerances, critical surface flatness, and high throughput.
Laser Marking & Traceability Station
Industrial laser marking workstations etch high-contrast part numbers, QR codes, batch IDs, and logos onto finished surfaces. Ensures 100% full-lifecycle component traceability and seamless quality tracking.
CMM Quality Inspection Room
Enclosed, temperature-stabilized measuring lab equipped with high-accuracy Hexagon coordinate measuring machines. Advanced touch-trigger probes verify complex 3D profiles, hole locations, and geometric tolerances against CAD models before final release.
Finished Goods Warehouse
Neatly stacked, palletized finished components awaiting final packaging and global dispatch. Systematic floor layout, standardized protective racking, and strict inventory control preserve part cleanliness and prevent damage prior to shipment.
