Quality Control
H01N2-D EN 50525-2-81 Welding Cable
Raw Material Test
NPC has always chosen raw material suppliers who have a good reputation, possess stable supply capabilities and have passed international quality system certifications (such as ISO 9001). And establish a long-term cooperative relationship with it, forming a stable and reliable raw material supply chain.
We will ensure that all raw materials are subject to strict inspection procedures upon entry to the factory, and can only be stored in the warehouse after they have been confirmed to meet the standards.
Process inspection
NPC has strict quality control procedures for each process in the cable production process.
Process documents: Develop detailed process flow and operation instructions to clarify the operating specifications and quality standards of each process.
Equipment calibration: Regularly calibrate key equipment such as wire drawing machines, stranding machines, extruders, and diameter gauges to ensure that the accuracy meets the requirements.
First piece confirmation: Before each batch of production, the first piece is trial-produced to confirm that the process parameters, product dimensions, electrical performance, etc. meet the standards before mass production can be carried out.
Finished Product
Inspectors conduct ex-factory inspections on cables according to relevant standards and corresponding product inspection specifications to ensure that each ex-factory product complies with the process regulations.
