Capabilities
CNC Machining & Die Casting for Automotive Components
At Wometal, we combine CNC machining and die casting to produce precision automotive components with the strength, accuracy, and finish required for modern vehicles.From one-off prototypes to high-volume production, our processes are built around quality, consistency, and speed.
CNC Machining Capabilities
Our CNC machining workshops operate 3-axis to 5-axis centers for aluminum and stainless-steel components.
We specialize in:- Tight tolerance machining (±0.01 mm typical)
- Small-batch prototyping and custom low-volume production
- Turning, milling, drilling, and threading operations
- Precision automotive parts for chassis, cooling, and EV systems
Each CNC machined automotive component is inspected using digital calipers, micrometers, and CMM measurement systems to ensure accuracy and repeatability.
Die Casting Capabilities
Our die casting division produces high-strength, lightweight aluminum automotive components.
Capabilities include:- High-pressure die casting up to 800 T clamping force
- In-house mold design and optimization for better filling & ejection
- Post-machining, deburring, and surface finishing (anodizing, powder coating, polishing)
- Integration with CNC machining for critical tolerance areas
Engineering & Process Support
Every project begins with a DFM (Design for Manufacturability) review.
Our engineers work closely with customers to balance weight, cost, and mechanical performance.
We help optimize:- Part geometry and wall thickness
- Draft angles and fillets for die casting molds
- Tooling life and process stability
- Surface finishing and assembly compatibility
Surface Finishing Options
We provide a complete range of finishing services to enhance performance and aesthetics:
- Anodizing / Hard Anodizing (for corrosion resistance & appearance)
- Powder Coating / Painting
- Polishing / Bead Blasting / Sandblasting
- Laser Marking / Custom Logo Engraving
These finishing processes make our automotive components and parts ready for both OEM and aftermarket markets.
Materials & Lightweight Design
Lightweight Aluminum Automotive Components
Modern vehicles demand lighter, stronger, and more efficient parts.
At Wometal, we focus on lightweight aluminum automotive components that combine excellent mechanical strength, heat dissipation, and corrosion resistance.We also work with stainless steel, zinc alloy, and engineering plastics for applications where specific strength or appearance is critical.
Our engineering team selects the most suitable material based on load requirements, operating temperature, and surface finishing needs.Quality & Inspection
Quality Inspection for Automotive Components
Every automotive component we manufacture undergoes strict quality inspection to ensure precision, safety, and reliability.
From CNC machining to die casting, our quality control process tracks every stage—from raw materials to final shipment—guaranteeing that every part meets your drawing and tolerance requirements.

Our Quality Assurance Process
We apply ISO-based inspection routines and traceability for every production batch:
- Incoming Material Verification – alloy composition, certificates, and hardness check
- In-Process Inspection – dimensional measurement and SPC during machining
- Final Inspection – 100% visual and functional check before packing
- CMM Measurement – 3D coordinate inspection for tight-tolerance automotive components
- Documentation – COC, PPAP (on request), and RoHS/REACH compliance
Tools & Instruments
We use professional inspection and measurement tools for precision verification:
- Coordinate Measuring Machine (CMM)
- Digital calipers & micrometers
- Surface roughness tester
- Thread gauges & plug gauges
- 3D optical measurement system
Why It Matters
Consistent quality builds long-term trust.
By maintaining strict tolerance control and traceable quality data, we help OEM and aftermarket customers reduce rework, shorten lead times, and ensure stable supply across global projects.Applications & OEM Supply
