1. Secondary Inspection of Raw Materials

MTSCO raw materials come from large factories such as Baosteel, TSINGSHAN, Yongxin...Each batch of raw materials requires MTC and PMI. After the raw materials arrive, we conduct PMI, appearance, heat no checking, physical and chemical and other inspections, to ensure that they meet the requirements.
Next, the raw material will be produced from cutting, forging, solid solution for flange blanks, through 100% visual inspection, 2% NDT, physical and chemical testing, etc., to confirm that the blanks are qualified. All experimental results are archived.

2. Traceability of the Production Process

The director receives the blanks from warehouse according to the production plan, and with the process flow card, the blanks are processed by turning, drilling, marking, cleaning and other procedures. The first flange programmed by CNC each time is supervised by the director, who confirms that it is qualified and then continues production. Every 10 subsequent pieces are measured by the machinist and the measurement data is recorded. Each link is supervised by professional qc inspectors and photographed for archiving. The entire process uses process cards to ensure accuracy and traceability.

3. Inspection before Shipment

MTSCO has professional QC team to inspect the dimensions of the flange, verify the spray code, inspect the appearance, and take photos to record. We did not conduct a 100% inspection because we firmly believe that good quality must be produced through management, not inspection. Therefore, we have invested a lot of effort in production control to ensure the quality of the final product. In addition, we also accept third-party inspection, such as SGS, TUV, and BV.
