High Frequency Welding Machine High frequency welding machine, it provides a completely different finish than heat welding since its process it`s very different as well. This machine works with and electronic circuit that transmits a high frequency oscillation on a electric field alternating at high speed, the oscillation makes thermoplastic molecules to heat evenly to a melting point making them fuse completely after applying pressure and then refrigerating the materials resulting in a finished product that will be 100% waterproof with an airtight seal, flexible and with an impeccable visual finish while giving a higher stability, resistance and durability to projects with high climate exposure. Another advantage of radiofrequency its adaptability being able to penetrate on thicker materials or with multiple layers and adapt to different molds to cut on custom margins when needed. Some industries that benefit from this process are: automotive, medical, entertainment, stationery, fashion and household.

Wuguo Valve Company took the lead in the valve industry in 2003 to obtain the "AZ" safety registration, in 2007 as the "TS" after the implementation of the first batch of renewal units successfully obtained the "TS" certificate, and re-certified in 2012, the validity period For June 2016.
In 2015, the company began its third "TS" replacement. In September 2015, it was formally reported on the website of the State Bureau of Quality Supervision and was accepted in mid-October. Immediately after that, Hefei General Machinery Inspection Center requested a type test. The valve testing center of the Hefei General Machinery Inspection and Testing Center determined the product catalog and test requirements of the type test valve according to the company's application acceptance letter and product range, etc. in accordance with relevant regulations and standards. In January 2016, under the strong support of the Hefei General Institute, the company completed the prototype test of all the prototypes under the active cooperation of all employees of the company.
The type test of the valve is part of the TS recertification work. The next step is to conduct an appraisal review. Qualified organizations will perform qualification examinations on the company's production conditions, research and development capabilities, etc. Related preparations are being carried out in an orderly manner. In March 2016, all replacements will be completed.
Wuguo Valve completed the third "TS" renewal type test
The Special Equipment Manufacturing License ("TS Certificate") is a qualification certificate necessary for the valve manufacturer's production and operation. It is audited and issued by the AQSIQ, and is replaced every four years.
