1. Die Casting Department (铝镁压铸部)

As an integrated manufacturing powerhouse, our foundry bridges the gap between raw metallurgy and net-shape precision. Equipped with advanced cold chamber die casting machines ranging from heavy-duty 400T to ultra-scale 5000T, we provide the raw clamping force and precision process control needed for structural components. Our specialized lean lines seamlessly support both high-ductility aluminum A356 semi-solid rheocasting and thin-wall magnesium alloy structural casting with minimal gas entrapment.

2. Precision CNC Machining (精密机加工)

Our machining floor represents the pinnacle of high-volume post-casting refinement. Operating over 400 advanced CNC units within our 40,000㎡ facility, we achieve dimensional consistency that trivializes complex tool wear. By optimizing spindle speeds and feed rates specifically for non-ferrous alloys, we achieve critical tolerances up to ±0.01mm, eliminating the need for secondary calibration on your assembly lines.

3. Quality Control & Metrology (品质检测)

In the Tier-1 automotive supply chain, verification is everything. Our zero-defect policy is enforced by an ISO/IATF-compliant metrology laboratory running fully automated quality reporting. From material alloy validation to final volumetric coordinate mapping, every production lot undergoes strict Statistical Process Control (SPC) with standard Cpk tracking exceeding 1.33.

4. Secondary Operations & Surface Finishing (辅助与表面处理)

To deliver true one-stop turnkey convenience, Alumcasting hosts comprehensive post-machining treatment facilities within our IT-managed setup:

• Surface Finishing: Automated shot blasting, precision sand blasting, vibratory grinding, and multi-stage ultrasonic cleaning lines to ensure pristine, oil-free component surfaces.
• Heat Treatment: In-house T4, T5, and T6 tempering furnaces designed to enhance the tensile strength and elongation profiles of structural aluminum die-castings without dimensional distortion or blistering.
• Leak Testing: Advanced differential high-pressure air and water submersion leak test benches, guaranteeing 100% airtight seals for oil pans, valve bodies, and EV cooling plates.

The Backbone of Automotive Component Excellence

In the automotive Tier 1 and Tier 2 supply chains, consistency is as critical as precision. At Alumcasting, our CNC machining department is engineered specifically to meet the high-volume, high-tolerance demands of the global automotive industry. With a massive fleet of over 400 advanced CNC machining centers, we provide the redundant capacity and technical stability required for long-term vehicle programs, keeping your assembly lines risk-free.

Our Machining Powerhouse: 400+ CNC Units

Unlike small machine shops, our 40,000㎡ facility is optimized for the seamless post-processing of complex die-cast components:

• High-Speed CNC Centers: Tuned for high feed rates and optimized thermal stability when cutting aluminum and magnesium alloys, achieving cycle times that keep your project on schedule.
• Precision Turning Centers: Specialized for Automotive Shafts and Valves, utilizing rigid spindle bearings to maintain perfect connectivity and ultra-smooth surface finishes up to Ra 0.8.
• 5-Axis Milling Capability: Built for highly intricate structural engine mounts and chassis brackets that require single-setup accuracy to prevent stacked geometric tolerances.
• ±0.01mm Tolerance Control: Every high-performance machining cell is subject to routine laser interferometer calibration to ensure your most critical automotive fits meet the strict 0.01mm threshold.

Advanced Inspection: The Final Gate

An equipment list is nothing without technical verification. Our machining floor is directly supported by a world-class metrology lab:

• CMM (Coordinate Measuring Machines): Automated multi-axis CMM (utilizing Hexagon/Zeiss platforms) for rapid, programmatic inspection of complex 3D profiles.
• Air Gaging & Digital Micrometers: For micro-level, real-time measurement of high-precision valve bores, fluid passages, and shaft diameters.
• X-Ray & Spectrometers: Non-destructive real-time industrial X-ray imaging and optical emission spectrometers ensure sub-surface material integrity and absolute porosity control before and after tooling contact.

Frequently Asked Questions

How does your 400+ CNC capacity benefit my automotive project?

Scale ensures supply chain insurance. With 400+ CNC units online, we can dedicate standalone production cells exclusively to your program. This redundancy eliminates queue bottlenecks common in smaller machine shops, facilitates flawless preventative tool-wear changes, and comfortably absorbs sudden OEM production ramp-ups.

Do you have dedicated equipment and safety protocols for magnesium machining?

Yes. Magnesium micro-chips and dust are highly combustible, requiring strict engineering isolation. We have physically segregated CNC workzones equipped with wet-type dust extractors, explosion-proof light fixtures, and customized synthetic coolants. Our operators are explicitly trained in magnesium handling to guarantee continuous, hazardous-free operations.

How do you maintain structural accuracy across such a massive fleet of machines?

Every CNC unit follows a hard-scheduled preventive maintenance routine calibrated via laser interferometers to correct geometric deviations. In parallel, our Statistical Process Control (SPC) software samples active station dimensions directly from the line, ensuring machine capability indices (Cpk) consistently trend above 1.33 for strict compliance.

Can your machining department handle large-scale structural parts like EV battery trays?

Our facility layout links our high-tonnage 5000T cold-chamber die casting line directly to an array of large-travel horizontal and multi-axis CNC milling machines. This specialized line is structurally optimized to mill extensive surface areas, profile complex perimeter gasket channels, and thread mounting bosses on complex EV battery trays or motor housings while holding global flatness requirements.
