A Complete OEM Partner for Excavator Manufacturing
Integrated Design-to-Delivery Capabilities
THACO INDUSTRIES operates within a 320-hectare, USD 1 billion manufacturing center in Chu Lai, Vietnam – one of Southeast Asia’s most advanced industrial campuses with a fully integrated production chain.
This integration allows us to maintain full control over cost, quality, and delivery timelines. As a certified excavator attachment manufacturer and excavator spare parts manufacturer, we serve OEMs that require large-scale production with strict compliance to ISO 9001:2015, ISO 14001:2015, CE marking, RoHS, and REACH requirements.
What THACO INDUSTRIES Capabilities
1. Excavator Attachments
THACO INDUSTRIES designs and fabricates heavy-duty excavator attachments including buckets, couplers, and shovels engineered for endurance and precision. Using fiber-laser cutting, CNC presses, and automated welding, we ensure a perfect fit and superior wear resistance. These attachments are ideal for high-impact applications in mining, quarrying, and construction, where performance and service life are paramount.
2. Undercarriage Parts
Our undercarriage parts rollers, sprockets, and idlers are manufactured from high-strength steel and processed through precision machining and heat treatment. Each component is designed to withstand heavy loads, abrasive conditions, and long operational cycles. Rigorous testing ensures consistent hardness and mechanical integrity for demanding sites worldwide.
3. Excavator Spare Parts
As a certified excavator spare parts manufacturer, THACO INDUSTRIES supplies critical components such as hydraulic cylinders, pumps, and system housings. All are built under strict quality-management frameworks to meet international OEM specifications. Our replacement parts deliver lasting performance, enabling clients to reduce downtime and extend equipment lifespan.
4. Electrical Parts
In our dedicated electrical division, wire harnesses, control modules, and sensor assemblies are produced using automated cutting and crimping lines. Designed for precision and safety, these electrical systems optimize excavator performance while supporting broader industrial and automotive applications.
5. Engine Parts
As an advanced excavator parts manufacturer, THACO INDUSTRIES produces engine blocks, crankshafts, pistons, and housings using CNC machining, aluminum casting, and five-axis milling technology. Each part is inspected through CMMs (Coordinate Measuring Machines) and non-destructive testing to ensure compliance with global OEM standards.
6. Custom Excavator Components
With a team of experienced R&D experts and engineers, we collaborate with customers to co-develop custom excavator components using CAD/CAM, 3D prototyping, and simulation analysis. This capability allows clients to source tailor-made, ready-to-install parts that integrate seamlessly into global OEM projects.
Excavator Parts Manufacturing Process
Material Preparation & Cutting
Every component begins with precise material preparation using slitting lines, CNC cutters, and advanced fiber-laser systems. These technologies ensure uniformity and tolerance accuracy from the very first process, setting a foundation for components that meet ASTM and OEM mechanical standards.
Machining & Shaping
Prepared blanks are transformed in CNC machining centers equipped with five-axis mills, hydraulic presses, and automated molding lines. Continuous program verification and dimensional checks ensure precision across complex geometries crucial for excavator undercarriages and engine components, where accuracy directly impacts performance.
Heat Treatment & Hardening
Wear-intensive components such as track links and sprockets undergo vacuum heat treatment and tempering. Metallographic analysis validates microstructure consistency, improving wear resistance and tensile strength. These processes guarantee the durability needed for heavy-duty excavation and mining operations.
Surface Treatment & Painting
Each component is shot-blasted, powder-coated, or ED-painted to protect against corrosion. Salt-spray and coating-thickness testing confirm surface quality. The result: clean, durable finishes that enhance handling, reduce corrosion, and extend product life in harsh environments.
Assembly
Coated parts go to specialized assembly lines where mechanical, hydraulic, and electrical systems are integrated into finished industrial equipment
Labeling & Serialization
All excavator parts are barcoded and serialized, allowing full digital traceability from casting to shipment. This ensures compliance, supports aftermarket maintenance, and simplifies part verification for global partners.
Inspection & Quality Testing
Our final inspection process includes dimensional verification, pressure testing, and vibration testing, using advanced CMMs. Operating under the ISO 9001:2015 system, THACO INDUSTRIES ensures every product meets international safety and performance benchmarks before delivery.
Packing & Delivery
Post-inspection, components are packed in moisture-resistant crates and reinforced export boxes. We use ERP-based logistics management to streamline customs clearance and shipping coordination. With optimized packaging and global logistics networks, we guarantee on-time delivery for every order.
