fabrication & machining
Machining
We use professional CNC equipment—including lathes, milling machines, and drilling machines—supported by CAD-based programming to machine parts from blanks to finished components. In-process inspection and CMM verification ensure critical dimensions remain accurate and consistent.
Cutting
We precisely cut raw materials such as high-strength steel and wear-resistant alloys according to product drawings. Using laser cutting and flame cutting, we efficiently process complex plates and profiles. Computer nesting improves material utilization and reduces waste, while fume purification supports cleaner production. Cut edges are smooth and free of oxide layers; parts are then verified for dimensions and identification before moving to the next process.
Bending
We form cut plates into the required shapes for key structural components (e.g., cab frames, sticks, and booms). CNC press brakes deliver precise, repeatable bends using preset angles and pressure parameters, minimizing manual variation. Settings are adjusted for different material thicknesses to prevent cracking or distortion and to maintain consistent bend angles. Finished parts undergo geometric tolerance checks to ensure proper fit-up and improved structural rigidity and load capacity.
Welding
Welding is the core step in forming the bucket structure, assembling components into a complete bucket. We use gas metal arc welding with a combination of welding robots and skilled welders to produce sound welds without porosity or slag inclusions. Workpieces are cleaned and preheated before welding, and inspected afterward using NDT (e.g., ultrasonic testing) to detect defects and improve fatigue strength and service life for demanding working conditions.
Painting
Our painting process uses a fully automated bake-curing line. Welded buckets are shotblasted to remove rust, contaminants, and scale to ensure strong coating adhesion. Powder coating is then applied to meet customer color requirements, followed by curing at 180–190°C in a temperature-controlled oven to create a hard, durable finish with excellent adhesion. This improves outdoor service life and delivers a clean, professional appearance.

Plate Incoming Hardness
Inspection
Hardness testers are used for sampling inspection of incoming plates. The Rockwell/Brinell hardness values are accurately determined to ensure that the raw material performance meets production standards and avoid material defect risks from the source.
Plate Bending Inspection
Specialized gauges are adopted to measure the bending angle, bending radius and plate flatness. The bending dimensions are checked against the drawing tolerances to ensure the forming accuracy of bent parts and meet the subsequent assembly adaptation requirements.
Inspection of Machined
Shafts and Bushings
With the help of micrometers and other equipment, the diameter tolerance, roundness and coaxiality of shafts, as well as the inner diameter and wall thickness uniformity of bushings are inspected. This ensures the dimensional accuracy of precision mating surfaces and improves the stability of transmission components.
