Introduction
We provide one-stop precision manufacturing services for conventional fuel vehicles and new energy vehicles (including key EV systems), covering die casting, sheet metal fabrication, CNC machining, stamping, and precision tooling across the full value chain. Backed by IATF 16949 automotive quality system certification, we deliver highly consistent and reliable components for Tier 1/Tier 2 suppliers and OEMs, meeting demanding requirements such as lightweighting, vibration resistance, waterproofing, and high-voltage safety—from R&D prototyping to million-unit mass production.
Automotive Product Manufacturing Services
WLD Manufacturing provides a complete suite of advanced production technologies tailored for critical vehicle prototypes and volume production parts.
Die Casting Process
We mass-produce die castings for automotive powertrains, chassis structures, body interiors, and new-energy e-drive systems. Aluminum and zinc alloy high-pressure die casting delivers strong integration, high strength, effective light weighting, and stable dimensions for precision volume supply to ICE and EV programs.

Sheet Metal Fabrication
We take on underbody and chassis guards, onboard electrical enclosures, high-voltage distribution housings, and interior structural sheet metal. Laser cutting, precision bending, and welded assembly yield robust structures, clean appearance, and durable corrosion protection for custom and volume builds of shells, racks, and protective parts.

CNC Precision Machining
We specialize in precision machining of powertrain shafts, chassis driveline parts, new-energy connection and heat-dissipation components, plus dedicated fixtures and checking tools. Multi-axis CNC holds tight tolerances and assembly fit for complex contoured and high-accuracy parts—from prototypes through low-to-medium batch production.

Metal Stamping Process
We focus on volume stamping of body structural parts, electrical conductive connectors, and interior hardware. Progressive and continuous stamping deliver stable forming, good interchangeability, and strong value—ideal for high-volume supply of standard automotive hardware.

Quality Control
At WLD Manufacturing, quality is our top priority. We implement strict quality control measures throughout the manufacturing process to ensure every automotive component meets the highest standards of precision and reliability. Our comprehensive quality assurance system includes advanced inspection tools and techniques to maintain consistency and excellence in our products.
In-Process Inspection
Raw material incoming inspection includes batch-by-batch spectral analysis for automotive-grade aluminum, zinc, stainless steel, carbon steel, and copper. We verify grades, hardness, and mechanical properties, strictly rejecting non-compliant materials. Production process control locks in standard parameters for die casting, sheet metal, CNC, stamping, and tooling. We execute first-article confirmation and regular routing inspections, checking critical dimensions and cosmetic defects, with error-proofing mechanisms in place. Tooling lifecycle management ensures regular maintenance and precision calibration for consistent mass production.
Final Inspection
Before shipment, finished products undergo final inspections for full dimensions, appearance, and assembly fit. We conduct sampling tests for hardness, tensile strength, and salt spray corrosion resistance. Surface treatments (anodizing, powder coating, plating, electrophoresis) are fully inspected for appearance and adhesion. All batch records are retained for full traceability, supporting customer audits and 8D closed-loop corrective actions combined with DFM optimization.
Precision Measurement Equipment
Equipped with professional precision testing instruments such as CMMs, optical measuring devices, high-precision calipers, and dial indicators, we inspect strictly according to GD&T standards: CNC machined parts up to ±0.005mm; Sheet metal/stamping critical dimensions ±0.05mm; Die casting standard tolerances ±0.1~0.3mm. 100% full inspection of all critical automotive assembly dimensions ensures perfect fit without interference.
System Certification
We are strictly certified with ISO 9001, ISO 14001, IATF 16949, and AS9100D. We utilize the five core tools of the automotive industry (APQP, PPAP, FMEA, SPC, MSA) for full-process control. We support OEMs with first-article approval and mass production data submission, meeting the supply standards of Tier 1/Tier 2 and high-end precision components.
