THACO INDUSTRIES, a leading Vietnamese manufacturer in the automotive and supporting industries, highlights the essential factors that define a trusted partner for global OEMs and Tier-1 suppliers.
Trusted automotive parts manufacturing for global OEMs
Car Parts Manufacturers: Driving Innovation and Reliability in the Automotive Industry
In today’s fast-changing automotive landscape, car parts manufacturers do more than produce components. They also serve as strategic partners in innovation. By delivering precise metal, plastic, and electrical components, they help ensure the performance, safety, and long-term durability required in modern vehicles.
Beyond manufacturing, these partners collaborate closely with OEMs to accelerate design cycles, adopt lightweight materials, and facilitate the industry’s shift toward electrification and sustainability. Through this evolution, manufacturers have become essential contributors in global supply chain stability and long-term competitiveness.
Innovative and reliable automotive parts manufacturing
Global Industry Overview and Market Trends
The automotive parts manufacturing industry spans thousands of suppliers worldwide and is rapidly transforming with shifting production bases and new technologies.
- Diversification and relocation: Production is expanding toward emerging markets like Vietnam, where manufacturers capable of integrating multi-material manufacturing processes (metal, plastic, and wiring harness) within a single, integrated supply chainincreasingly sought after by EU and Asian OEMs.
- Lightweight and electrification trends: The industry is placing greater emphasis on advanced lightweight materials, including high-strength aluminum alloys, lightweight welded frames, and high-precision brackets to enhance energy efficiency and support EV range optimization.
- Packaging and logistics requirements: EU buyers emphasize returnable packaging, modular kitting, and barcode or QR labeling to improve traceability and sustainability throughout the supply chain.
Quality and Compliance – The Foundation of Reliability
For any car parts manufacturer, quality assurance and compliance form the backbone of reliability. Adhering to global standards such as IATF 16949, ISO 9001, and UNECE ensures consistent safety and performance.
Manufacturers employ quality tools including PPAP, FAI, Control Plan, PFMEA, SPC, and MSA to minimise risks and maintain full traceability in line with OEM requirements. Compliance with IMDS, REACH, ELV, and RoHS further ensures environmental responsibility and enhances transparency throughout supply chain transparency.
| Area | Main Requirements / Tools | Applicable Standards |
| Core Quality Tools | PPAP, FAI, Control Plan, PFMEA, SPC, MSA | IATF / AIAG |
| Wiring Harness | 100% continuity, hi-pot test, crimp height/pull-force checks | IPC/WHMA-A-620 |
| Plastic Parts | Color & texture control, flammability, UV, gloss checks, moldflow analysis | FMVSS 302 / ISO 3795 / VDI Texture |
| Regulatory Compliance | Material data submission, labeling & IMDS traceability | UNECE (R43, R124, R129), REACH, ELV |
Core Product Categories and Manufacturing Capabilities
A trusted car parts manufacturer must demonstrate technical breadth, handling metal, plastic, and electrical systems under one integrated process.
Steel Wheels
Made from high-strength steel through rim forming, ring welding, and dynamic balancing, these wheels comply with relevant ECE R124 requirements for steel rims. They undergo fatigue, cornering, and endurance testing to ensure stable performance and operational safety. Impact testing is generally less critical for steel wheels compared to aluminum alloy wheels, which are more prone to fracture under load.
Automotive Glass
Including laminated windshields and tempered side or rear glass, these components follow ECE R43, meeting stringent optical and environmental resistance standards through processes like thermal bending and PVB lamination.
Automotive Glass
Wiring Harness
The electrical backbone of vehicles, wiring harnesses are produced using automated cutting, crimping, and braiding. Each assembly passes 100% continuity and hi-pot testing, meeting IPC/WHMA-A-620 standards for durability and reliability.
Wiring Harness
Leaf Springs
Supporting vehicle load and suspension stability, these parts are made from heat-treated spring steel and coated for corrosion protection. They are tested for fatigue, load-deflection, and salt spray resistance.
Radiator & Condenser
Key components for engine cooling and HVAC efficiency, produced with aluminum brazing, pressure/leak testing, and durability validations such as thermal cycling and vibration tests to ensure stable performance.
Exterior Accessories
Including roof racks, bull-bars, and side steps, these components are manufactured with tube bending and jig welding. Each is tested for load and weld durability, meeting UNECE pedestrian safety standards.
Child Seat & Interior Components
Featuring ISOFIX brackets, seat rails, and trims, these parts combine stamping, welding, and injection molding, tested per UNECE R44/R129 for maximum passenger safety.
Child Seat & Interior Components
Canopy & Dry Box
Used in commercial vehicles for storage and protection, these assemblies undergo vibration, roof load, and water-tightness testing, ensuring strength and reliability.
Plastic Injection Components
Produced for both passenger and commercial vehicles: including bumpers, hubcaps, dashboard panels, ducts, and seat covers, these parts are validated through flammability, UV, and dimensional accuracy checks, using advanced resins such as PP, ABS, PC+ABS, and PA66-GF.
