Manufacturing medium frequency melting furnace quality assurance measures

Manufacturing medium frequency melting furnace product quality control measures

In the quality control, we have established a complete set of quality system documents in strict accordance with the ISO9001 quality standards.

1. When selecting raw materials and external parts, our company has established a complete qualified sub-supplier to ensure the quality of raw materials and external parts.

2. In the production process, each component has a quality responsibility tracking card, which indicates the responsible person of each processing step and the final inspector. For key components such as sensors, yokes, etc., there are special codes of practice to ensure that the parts that fail the upper pass never flow into the next process.

3. The factory inspection should be carried out before leaving the factory. The contents include visual inspection, mechanical size inspection, insulation inspection of induction coils, withstand voltage test and hydraulic test. The furnace operation check of the electric furnace, the inspection of the hydraulic system and the test of various parameters of the intermediate frequency power supply. After all the inspections are completed, the inspector fills in the product qualification certificate, and records the various test data to ensure that the product quality is traceable.

2) Manufacturing medium frequency melting furnace product quality guarantee

1. The intermediate frequency melting furnace is made of a new high-quality material that is compatible with the technical specifications of the intermediate frequency melting furnace. All the substantive aspects are consistent with the specifications of the intermediate frequency melting furnace technical specifications.

2. The main external parts of the intermediate frequency melting furnace have the product certificate issued by the original manufacturer.

3. The intermediate frequency melting furnace is guaranteed for 12 months from the date of final acceptance. During the warranty period, if the intermediate frequency melting furnace is faulty due to poor manufacturing or poor quality of the external parts, repair or replace the corresponding parts for the buyer free of charge.

4. Provide 24-hour response service. Send someone within 36 hours of receiving the user service request.

5, to ensure the stability of parts production, long-term supply of spare parts to the user at a preferential price (lower than the market price of the same period).
