THACO INDUSTRIES – OEM components manufacturer in Vietnam

As Vietnam’s leading OEM components manufacturer, THACO INDUSTRIES integrates precision engineering with large-scale production capabilities. Spanning a 320-hectare campus with 22 manufacturing plants and companies, THACO INDUSTRIES delivers a full value chain from R&D and manufacturing to installation and maintenance. Its integrated model supports global clients with consistent, audit-ready components for automotive, industrial, and high-tech sectors, all certified under internationally recognized standards such as ISO 9001:2015 and IATF 16949:2016.

The sourcing challenge we solve

Global OEM buyers face significant supply chain challenges, particularly when scaling complex parts across fragmented vendor networks. Common challenges include inconsistent quality, shifting specifications, delayed compliance documentation, and extended tooling lead times.

Fragmented vendor networks

Many supply chains still depend on separate workshops for casting, welding, painting, and finishing. Each handoff increases the risk of late deliveries or mismatched specifications. Without a single source of accountability, buyers face unpredictable quality and costly rework.

Quality drift

When production is spread across multiple vendors, tolerances tend to shift over time. A fraction of a millimeter on a stamped panel or a change in surface coating can compromise assembly fit, durability, or safety. Revalidating these changes consumes engineering resources and slows down the launch process.

Delayed PPAP submissions

In the automotive sector, Process Part Approval (PPAP) documentation is mandatory. Yet some suppliers provide incomplete documentation weeks behind schedule. This delays project milestones and threatens compliance with OEM and regulatory standards.

Unclear Incoterms application

International Commercial Terms (Incoterms), such as Free on Board (FOB) or Cost, Insurance, and Freight (CIF), define the roles and responsibilities in global trade. Misinterpretations lead to unexpected charges, stalled shipments, or disputes, all of which erode buyer trust and timelines.

Extended tool lead times

Relying on separate tool shops can stretch mold or die production into several months. Each delay cascades into postponed first articles and missed production windows, forcing OEMs to absorb higher costs or lost market opportunities.

These challenges demonstrate why decision-makers seek integrated manufacturers that can manage the entire process under one roof. The goal is to ensure speed, consistency, and compliance from the first tool cut to final delivery.

THACO INDUSTRIES – Leading OEM product manufacturing and supplying partner in Vietnam

Choosing the right Vietnam OEM manufacturer goes beyond low cost. Global buyers want assurance that complex components can be developed, produced, and delivered without full transparency and minimal risk. THACO INDUSTRIES provides that assurance through a fully integrated operating model that connects product design, industrial engineering, and high-volume production under one operation. This structure reduces delays and eliminates the coordination problems that often appear when multiple vendors share responsibility.

With a proven export track record across North America, Europe, and the Asia-Pacific, THACO INDUSTRIES demonstrates its ability to meet diverse market requirements and regulatory standards. Every project is supported by internationally recognized systems, including ISO 9001:2015 and IATF 16949:2016, ensuring consistent quality across a wide range of components. From early-stage validation through to mass production, THACO INDUSTRIES applies strict process control, helping buyers keep projects on schedule and compliant with technical specifications, and aligned with global OEM standards.

Integrated capabilities (Under One Roof)

Stable, high-volume OEM production works require seamless connection across every stage of the manufacturing cycle. At THACO INDUSTRIES, all processes follow a coordinated flow, from precision processing to final assembly. This reduces variation and strengthens part reliability at scale.

• Precision Processing: CNC turning and 3-5 axis milling deliver tight-tolerance parts for structural or motion-critical functions. Jigs, fixtures, and CMM inspection confirm dimensional accuracy.
• Die Casting and Post-Machining: Aluminium and zinc components are pressure-cast and heat-treated, then finished with CNC post-machining. Leak testing and deburring ensure clean, functional output.
• Plastic injection molding in Vietnam: High-tonnage presses support overmolding and insert molding, enabling both structural and aesthetic applications. THACO INDUSTRIES ensures consistent surface finish, texture, and color control across components.
• Metal Stamping and Forming: High-volume metal stamping in Vietnam utilizes progressive dies, laser cutting, bending, and tapping to shape parts with precision. THACO INDUSTRIES applies these processes to meet tight tolerances and fast turnaround expectations.
• Welding and Fabrication: Robotic and manual welding handle frames, chassis, and heavy-duty parts. Advanced joining techniques and high-strength steels support long-term performance.
• Surface Treatment and Painting: Powder coating, ED-coating, and galvanizing increase durability. Salt-spray testing validates corrosion resistance.
• Electrical Assemblies and Wire Harness in Vietnam:  Capabilities include precision cutting, crimping, stripping, twisting, and assembly. Every harness undergoes full functional testing to ensure electrical reliability and integration across systems.
• Sub-Assembly and Finished Assembly: Multi-process components are kitted, tested, and prepared for export.
• Molds, Dies, and Tooling: In-house mold and die production supports specialized components with ongoing maintenance.

Quality and compliance

THACO INDUSTRIES operates in line with global OEM and automotive standards. This gives OEM buyers confidence that every program aligns with global requirements. THACO INDUSTRIES’s management systems are certified to IATF 16949:2016, ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018. Products also comply with CE, REACH, and ROHS requirements. The other elements of our quality approach include:

• Automotive-grade validation. Tools such as PPAP, FMEA, control plans, MSA, and SPC are applied to reduce risk and maintain stable production output.
• Metrology and testing. CMMs, gauges, salt-spray chambers, and functional evaluations verify that every component meets dimensional and durability requirements.
• Traceability. Each part is thoroughly documented, from raw material intake through final inspection, supporting audit readiness and facilitating rapid root-cause analysis in the event of issues.

Project delivery – From RFQ to ramp

OEM programs require a structured approach, from quote to ramp-up. That’s why THACO INDUSTRIES sets clear checkpoints from the first file transfer to full-scale production. This reduces friction at every stage and keeps part timelines and quality aligned.

• RFQ & NDA: Projects begin with secure intake of technical files (STEP/IGES/PDF/BOM) and clarity around volumes, tolerances, and Incoterms.
• Engineering Reviews: DFM/DFA analysis guides smarter tooling choices and improves component performance while controlling cost.
• Tooling & Validation: In-house molds, dies, and fixtures shorten lead times. First articles undergo capability studies and dimensional reporting.
• PPAP Submission: For automotive parts, THACO INDUSTRIES delivers full PPAPs with control plans, PFMEA, MSA, and packaging trials.
• Ramp-Up: Production is scaled with takt-aligned processes, capacity planning, and in-line inspection.
• Sustaining Support: Long-term programs benefit from 8D corrective action, obsolescence plans, and continuous cost-down options.
