Automotive-Grade Assurance
Fully IATF 16949 and ISO 9001 certified processes guarantee compliance with the most stringent industry standards.
Ultra-Tight Accuracy
CNC machining to ± 0.02 mm ensures perfect mating surfaces, sealing faces, and bearing journals.
Integrated In-House Workflow
From mold design and die casting to CNC machining, heat treatment, and finishing—no third-party delays.
High-Performance Materials
Squeeze casting option yields near-forged density; aluminum alloys deliver superior strength-to-weight ratios.
Rapid Prototype to Production
Validate with a single prototype; seamlessly ramp to thousands of parts without changing vendors.
Comprehensive QC & Reporting
Every batch includes detailed CMM reports, porosity scans, and full material certifications.
Hybrid Casting-Additive Techniques
Embedding 3D-printed cores in conventional molds enables complex cooling and oil-channel geometries.
Next-Gen Alloys & Coatings
Adoption of Al–Li and metal-matrix composites alongside ceramic/DLC coatings for extreme wear resistance.
Smart Factory Integration
IoT-enabled presses and CNC centers feed real-time data into AI systems for predictive maintenance and zero-defect yields.
Sustainable Circular Production
Closed-loop coolant systems, recyclable lubricants, and scrap-reduction strategies minimize environmental footprint.
Automotive Powertrains
Cylinder heads, transmission housings, oil pump bodies, turbocharger compressor covers.
Motorsports & Performance
Lightweight pistons, custom intake manifolds, brake caliper brackets, performance‐grade engine mounts.
Industrial Engines & Generators
Robust pump housings, valve bodies, mounting flanges for diesel and gas power units.
Marine & Off-Road
Corrosion-resistant crankcase halves, impeller covers, differential housings.
Hybrid & Electric Drive Systems
Structural battery housings, motor end-bells, heat-sink manifolds with integrated fluid channels.
