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 tools: diamond cutting tools, abrasive tools, drilling tools, alloy saw blades, carbide turning tools, milling cutters, reamers, planers, woodworking drill bits, etc.

2. Welding for various hardware and mechanical accessories: hardware bathroom products, refrigeration copper fittings, lighting accessories, precision mold fittings, hardware handles, egg beaters; silver soldering and copper soldering for the same metals or different metals such as alloy 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 irregular flat stainless steel pot bottoms with aluminum sheets, and can also be used for brazing of other metal flat surfaces.

4. The welding of heating plates for electric kettles (electric coffee makers) primarily involves brazing 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 a different shape using a punch press, forging machine, or other methods. Examples include: watch cases, watch blanks, handles, mold accessories, kitchenware, art crafts, 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 joining of different metals or metals with non-metals by heating the metal, utilizing the principles of thermal expansion or thermal melting to connect them. For example: the copper core of computer heat sinks with aluminum sheets, buried welding of speaker mesh, composite of steel-plastic pipes, sealing of aluminum foil motor rotors, and 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., for quenching.

2. Various auto and motorcycle accessories, including crankshafts, connecting rods, piston pins, chain wheels, aluminum wheels, valves, rocker arms, drive halfshafts, small shafts, and fork extractors, etc., hardening.

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

4. Machine Tool Industry. Such as quenching for machine tool beds and guideways.

5. Various hardware metal parts, machined components, including shafts, gears (chain wheels), cams, clamps, fixtures, etc., for quenching.

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

Four: Annealing (tempering, normalization)

1. Annealing services for various stainless steel applications, including pot and can stretching, rolling edges, sink annealing, stainless steel pipes, utensils, cups, and more.

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