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 components, hardware pulls, egg beaters, silver brazing and copper brazing of the same metals or different metals such as alloy steel 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 shapes of electric heating tubes.

Section 2: Heating (Hot Forging, Hot Fitting, Melting)

1. Hot forging primarily involves heating the workpiece to a certain temperature (which varies depending on the material), and then forging it into different shapes using a punch press, forging machine, or other methods. Examples include: watch cases, watch blanks, handles, mold accessories, kitchenware, handicrafts, standard parts, fasteners, mechanical component processing, copper locks, rivets, steel spikes, and hot extrusion of punch tools, etc.

2. Hot-forging primarily refers to the connection of different metals or metals and non-metals by heating the metals, utilizing the principles of thermal expansion or thermal melting to bond them together. Examples include: the copper core and aluminum sheet of computer heat sinks, the buried welding of speaker mesh, the composite of steel-plastic pipes, the sealing of aluminum foil, motor rotors, and the sealing of electric heating tubes, etc.

3. Melting it primarily refers to the process of converting metal into a liquid through high temperatures, 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 metallic materials through processes such as heating the workpieces, with specific applications including:

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

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

3. A variety of electric tools, such as gears and shafts.

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

5. Various hardware metal parts, machined components, 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 the annealing and stretching of stainless steel basins and cans, annealing rolled edges, as well as annealing for sinks, stainless steel pipes, utensils, cups, and more.

2. Annealing of various metalwork items, including golf ball heads, clubs, copper lock nuts, hardware copper accessories, vegetable knife handles, blades, aluminum pots, aluminum drums, aluminum radiators, and all types of aluminum products.
