Quality Control

At Nantong Kunya Machinery, quality is more than a standard - it's a fundamental principle that drives every stage of our manufacturing process. From raw material inspection to final machine commissioning, we implement strict quality control systems to ensure our equipment meets the highest industry standards for performance, durability, and safety.

 

Strict Raw Material Selection
We source key components such as steel, alloy, and electrical parts from verified suppliers. Each batch is inspected for mechanical strength, chemical composition, and surface integrity before production begins.

 

Precision Machining and Fabrication
All key components such as screw elements, barrels, shafts, and gearbox housings are CNC-machined to tight tolerances. Our internal workshops operate under ISO-controlled processes to maintain consistency across all product lines.

 

In-Process Quality Checks
Each step of the production process includes documented quality checkpoints. Our team uses calibrated tools and gauges to check tolerances, alignment, and surface finish at every critical stage.

 

Comprehensive Testing Before Delivery
All machines are subject to full-load testing prior to shipment. This includes:

• Mechanical running tests

• Electrical function verification

• Temperature and pressure monitoring

• Safety interlock system checks

• Test results are recorded and archived for every project.
