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.
Q1: What is the minimum order quantity?
A1: A single prototype part; subsequent production volumes can
scale from dozens to tens of thousands.
Q2: Which CAD formats do you support?
A2: 2D: DWG, DXF, PDF; 3D: STEP, IGES, STL.
Q3: How tight are your tolerances and finishes?
A3: Standard machining tolerance is ± 0.02 mm with surface finishes
down to Ra 0.4 µm; custom requirements accommodated.
Q4: Do you handle both casting and CNC machining in-house?
A4: Yes—our vertically integrated facility covers die casting, CNC
machining, heat treatment, and finishing for turnkey delivery.
Q5: What quality documentation is provided?
A5: Every order ships with material test certificates and full
inspection reports (CMM, X-ray, SPC).
Q6: What is the typical lead time?
A6: Prototypes in 7–10 days; production batches in 15–25 days after
tooling approval.
