Carefully select suppliers：Strictly select raw material suppliers, establish stable cooperative relationships, and implement regular evaluation and review mechanisms.

Warehousing inspection：Raw material incoming inspection, covering chemical composition, parameter indicators, etc.

Refined inventory management：Adopting advanced inventory management system to ensure suitable storage environment for raw materials, and conducting regular re inspections to ensure stable quality of raw materials.

Carefully select auxiliary materials：Based on production needs and technical standards, select high-quality auxiliary materials such as quenching oil and drawing powder.

Quality Verification：Each batch of auxiliary materials must undergo quality testing, with special attention paid to the cooling performance and stability of the quenching oil to ensure maximum efficiency of the auxiliary materials.

Standardization of processes：Develop and implement high standard production processes, with real-time monitoring and recording of key processes.

Process quality inspection：Establish multiple quality inspection points to quickly respond to and address quality issues, ensuring that each step meets quality standards.

Precision calibration of equipment：Regularly calibrate production equipment to ensure accurate operation and consistent quality of each batch of products.

Full batch quality inspection：Each batch of steel wire must undergo comprehensive quality testing before leaving the factory, and defective products are not allowed to flow out of the factory.

Appearance and size：Precision inspection of appearance and dimensional measurement to ensure flawless appearance and accurate dimensions of the steel wire.

Component analysis：Using high-precision detection equipment such as spectrometers to ensure that the chemical composition of the steel wire meets the standards and customer requirements.

performance testing:It includes all the necessary testing items for precise testing of tensile strength, cross-sectional shrinkage rate, weight, grade, winding, acid corrosion, torsion, decarburization, etc., to accurately evaluate the performance of steel wire.

Establish exclusive files for each customer, archiving the corresponding raw materials, auxiliary materials, chemical composition, material, process, shape, size, and other information of the purchased steel wire, ensuring that the quality of each batch of newly produced steel wire is consistent with the sample, stable and reliable.
