At Kaiping Zhonghe Machinery, Quality Control (QC) is a fundamental pillar of our manufacturing process, ensuring that every excavator attachment meets the highest standards of durability, precision, and performance. Our comprehensive QC system covers every stage of production—from raw material inspection to final product testing—guaranteeing reliability for customers worldwide.
1. Strict Material Selection & Inspection
- High-Grade Steel & Components: We source premium-quality steel and alloy materials from certified suppliers to ensure superior strength and wear resistance.
- Incoming Material Testing: All raw materials undergo hardness, tensile strength, and chemical composition tests before entering production.
- Traceability: Each batch of materials is documented for full traceability, ensuring consistency and accountability.
2. Advanced Manufacturing & Process Control
- CNC Machining & Precision Welding: Our state-of-the-art CNC machines and robotic welding systems ensure exact dimensions and structural integrity.
- Heat Treatment: Critical components undergo quenching, tempering, and stress-relief treatments to enhance durability.
- Real-Time Monitoring: Production processes are continuously monitored to prevent defects and maintain uniformity.
3. Rigorous Product Testing
- Load & Stress Testing: Attachments are subjected to dynamic load simulations to verify stability under extreme conditions.
- Welding Integrity Checks: Weld flaw inspections detect hidden flaws in welds.
- Functional Testing: Each arm, boom, or grab undergoes operational tests to ensure smooth movement and compatibility with excavators.
4. Final Inspection & Certification
- Dimensional Accuracy: Laser measuring tools confirm adherence to design specifications.
- Surface & Coating Inspection: Anti-corrosion treatments (e.g., sandblasting, painting) are checked for uniformity and adhesion.
- ISO Compliance: Our QC system aligns with ISO 9001 and other international standards, with certifications provided upon request.
5. Continuous Improvement & Customer Feedback
- Post-Sale Support: We collect field performance data to refine designs and address real-world challenges.
- Custom QC Solutions: For specialized attachments (e.g., long reach arms, demolition arms, tunnel booms), we tailor testing protocols to meet unique demands.
