Precision Manufacturing Process: Strength Built on Quality
ZHONGHE's manufacturing prowess is the foundation of our product excellence. We implement a strictly controlled, lean production process:
1. Precision Design & Material Selection:
Professional structural design and stress analysis based on application requirements.
Strict sourcing of top-tier global steel (e.g., Hardox wear plate, BS700/Q690D/Q355B structural steel).
2. High-Precision Cutting & Forming:
CNC plasma/flame cutting ensures dimensional accuracy with minimal thermal distortion.
Large structural components are precision-formed using heavy-duty press brakes and plate rollers.
3. Advanced Welding Technology:
Operated by internationally certified senior welders.
Extensive use of high-strength processes like GMAW (Gas Metal Arc Welding).
Critical joints feature double-beveled groove preparation (45°) with gas-shielded welding.
Key structural areas utilize double-pass welding.
4. Precision Machining & Assembly:
Large double-sided floor boring mills ensure high concentricity (±1mm tolerance) for pivot booms, extending lifespan.
5. Triple-Check QC Protocol: Zero Tolerance for Defects:
Design Review: Rigorous approval of drawings and technical plans.
In-Process Verification: 100% inspection after each manufacturing stage, checking prior process outputs. Problems are halted before proceeding.
Final Inspection: Our independent QC Department performs comprehensive checks, including:
Weld quality.
Critical dimensional accuracy (CMM - Coordinate Measuring Machine, ±1mm tolerance control).
Hydraulic system pressure and seal integrity tests.
Functional tests (range of motion, limit switch protection).
Only products passing all three mandatory quality gates receive shipment authorization.
