"Yongsheng tools"--manufacturing quality

Factory founded to begin, remained committed to the development, production, sale of electric welding pliers, protective face masks, hard hats, safety glasses, work gloves, reflective vests and other security protection industry a series of security products.
Enterprise has experienced technical force, large-scale design team, advanced processing and testing equipment, products are exported to Southeast Asia, the Middle East, South Africa, Europe and other countries around the world and the domestic rough hardware market.        
Adhere to the "quality first" as the goal, through a number of national testing standards, has won the national "CCC" certification, the European "CE" certification and United States, "ANSI" certification, firms in 2007 passed the international quality management system certification.        

External touch body made of high quality material of DMC, feel comfortable, and good insulation properties, high resistance to impact, heat-resistant strength

Internal conductive body is made of hammered copper, cast bronze or brass-plated parts, good conductivity and resistance at low heat;

Springs made of high quality spring steel, high elastic strength, ensure that the electrodes clamped solid, easy to fall off;

Insulated spring protection to ensure its good insulating properties;

According to the user's use of this information, combined with using attributes of the electrode holder, using a new design concept, make it more reasonable in structure, and the appearance is novel. And style all over the world (Germany, United States, Italy, Netherlands, Japan, Korea, France and traditional-style) meet the needs of users throughout;

Enterprises have passed the CCC product certification and passed the international quality system certification, product quality and safety with guaranteed.

Factory production welding clamp fastening and durable, insulating safety. Applicable to all kinds of manual AC and DC arc welder used, clamp the handle in bronze body with spring compression method connections, completely solve the electrode holder handle easy to loose a flaw in the process. Aerial copper body good heat dissipation in the handle, handle continuous work temperature is below 40 degrees.

Here's a little knowledge (about DMC material):
BMC also known as DMC (Dough molding compound), the molding. Domestic is often referred to as unsaturated polyester molding compound. Its main raw material consists of short glass fiber, unsaturated polyester resin, filler, as well as the mixture of additives fully mission-prepreg. DMC material in in the 1960 of the 20th century in the former West Germany and the United Kingdom, first used, and then separately in the 70 's and 80 's in the United States and Japan has been greater development. Because of its excellent electrical properties, mechanical properties, heat resistance, chemical resistance, and adapt to a variety of processing to meet the requirements of various products for performance, so more and more of the user's favorite.
