Welding (Soldering, Silver Soldering, Copper Soldering):

It primarily connects two metals, either of the same or different materials, by melting the solder through heating to a certain temperature. Specific applications include:

1. Welding of various hardware cutting tools: diamond cutting tools, abrasive tools, drilling tools, alloy saw blades, hard alloy turning tools, milling cutters, reamers, planers, and woodworking drill bits, etc.

2. Welding of various hardware and mechanical accessories: hardware bathroom products, refrigeration copper fittings, lighting accessories, precision mold accessories, hardware pulls, egg beaters, silver brazing and copper brazing of the same metal or different metals such as stainless steel and steel, steel and copper, copper and copper.

3. Composite pot bottom welding is mainly used for three-layer brazing of circular, square, and other irregularly shaped flat stainless steel pot bottoms with aluminum sheets, and can also be used for brazing of other metal flat surfaces.

4. The heat plate welding for electric kettles (electric coffee makers) primarily involves brazing between stainless steel flat bottoms, aluminum sheets, and various shapes of electric heating tubes.

Section Two: Heating (Hot Forging, Hot Fitting, Melting)

1. Hot forging primarily involves heating the workpiece to a certain temperature (which varies depending on the material), then forging it into a different shape through a press, forging machine, or other methods. Examples include: watch cases, watch blanks, handles, mold accessories, kitchenware, crafts, standard parts, fasteners, machining of mechanical components, copper locks, rivets, steel rods, and hot extrusion of punches, etc.

2. Hot-forging mainly refers to the connection between different metals or between metals and non-metals by heating the metal, utilizing the principle of thermal expansion or thermal dissolution to bond them together. For example: the copper core of a computer radiator with aluminum plates, the embedded welding of speaker mesh, the composite of steel-plastic pipes, the sealing of aluminum foil, motor rotors, sealed electric heating tubes, and so on.

3. Melting primarily refers to the process of converting metal into a liquid state through high temperatures, and is mainly applicable to iron, steel, copper, aluminum, zinc, and various precious metals, such as gold and silver.

Section 3: Heat Treatment (Surface Hardening):

It primarily alters the hardness of metal materials through processes such as heating the workpieces, with specific applications including:

1. A variety of hardware tools and hand tools, such as pliers, wrenches, hammers, axes, screwdrivers, and shears (garden shears), etc., heat treatment.

2. Various auto and motorcycle accessories, such as crankshafts, connecting rods, piston pins, sprockets, aluminum wheels, valves, camshafts, drive shafts, stub shafts, and detent pins, etc., for hardening processing.

3. Various electric tools, such as gears and shafts.

4. Machine tool industry category. Such as quenching for machine tool beds and guides.

5. Various hardware metal parts, machining parts, such as shafts, gears (chain gears), cams, clamps, fixtures, etc., heat treatment.

6. Hardware mold industry. Such as quenching for small molds, mold accessories, and mold bores.

Four: Annealing (tempering, quenching)

1. Annealing services for various stainless steel industries, including annealing stretching for stainless steel basins and cans, annealing rolling edges, as well as annealing for sinks, stainless steel pipes, utensils, cups, and more.

2. Annealing of various metal components, such as golf ball heads, clubs, brass lock nuts, hardware brass accessories, knife handles, blades, aluminum pots, aluminum drums, aluminum radiators, and all kinds of aluminum products.
