One. Welding (Soldering, Silver Soldering, Copper Soldering):

It primarily connects two metals, whether of the same or different materials, by melting solder at a certain temperature. Specific applications include:

1. Welding for various metal 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 soldering and copper soldering of the same metals or different metals such as brass and steel, steel and copper, copper and copper.

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

4. The heating plate welding for electric kettles (electric coffee makers) primarily involves soldering between stainless steel flat bottoms, aluminum sheets, and various shaped heating pipes.

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 using a press, forging machine, or other methods. Examples include: watch cases, watch blanks, handles, mold accessories, kitchenware, art crafts, standard parts, fasteners, machining of mechanical components, copper locks, rivets, steel rods, punch tools, and hot extrusion of similar items.

2. Heat-fusion primarily refers to the joining of different metals or metals with non-metals through heating the metal, utilizing the principle of thermal expansion or melting to bond them together. For instance: the copper core of computer radiators with aluminum sheets, buried welding of speaker mesh, composite of steel-plastic pipes, sealing of aluminum foil, motor rotors, sealed electric heating tubes, and more.

3. Melting refers to the process of heating metal to a liquid state, primarily suitable for metals like 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., are heat treated.

2. Various auto and motorcycle parts, including crankshafts, connecting rods, piston pins, sprockets, aluminum wheels, valves, rocker arms, drive halfshafts, small shafts, and detents, etc., heat treatment.

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

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

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

6. Hardware molds industry. Such as hardening of small molds, mold accessories, and mold internal bores, etc.

Four: Annealing (tempering, quenching)

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

2. Annealing of various metal components, including golf ball heads, clubs, copper lock nuts, hardware copper accessories, knife handles, blade edges, aluminum pots, aluminum drums, aluminum radiators, and all kinds of aluminum products.
