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 metal cutting tools: diamond cutting tools, grinding wheels, drill bits, alloy saw blades, hard alloy turning tools, milling cutters, reamers, planning cutters, and woodworking drill bits, etc.
2. Welding of various hardware and mechanical accessories: hardware bathroom products, refrigeration copper fittings, lighting accessories, precision mold fittings, hardware pulls, egg beaters, silver welding and copper welding for same metals like alloy steel and steel, steel and copper, copper and copper, as well as for different metals.
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 brazing between stainless steel flat bottoms, aluminum sheets, and various shapes of electric heating tubes.
Heating (Hot Forging, Hot Assembly, 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 press, forging machine, or other methods. Examples include: watch cases, watch blanks, handles, mold accessories, kitchenware, art crafts, standard parts, fasteners, machined mechanical components, brass locks, rivets, steel rods, and hot extrusion of punches, etc.
2. Hot fitting primarily refers to the joining of different metals or metals with non-metals by heating the metal, utilizing the principle of thermal expansion or thermal dissolution to connect them. For example: the copper core of a computer cooler with aluminum plates, the embedded welding of speaker meshes, the composite of steel-plastic pipes, the sealing of aluminum foil, motor rotors, and sealed heating elements, etc.
3. Melting primarily refers to the process of converting metal into a liquid state through high temperatures, which 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 workpiece, 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 parts, such as crankshafts, connecting rods, piston pins, chain wheels, aluminum wheels, valves, camshafts, drive shafts, small shafts, and tappets, etc., heat treatment.
3. Various electric tools, such as gears and shafts.
4. Machining equipment industry. Such as hardening of machine tool beds and guides.
5. Various hardware metal parts, machined components. Such as shafts, gears (chain wheels), cams, clamps, fixtures, etc., for quenching.
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 applications, including pot and can annealing stretching, edge rolling, and sink annealing, as well as stainless steel tubes, utensils, cups, and more.
2. Annealing of various metalwork items, such as golf ball heads, clubs, copper lock heads, hardware copper accessories, knife handles, blades, aluminum pots, aluminum drums, aluminum radiators, and all types of aluminum products.
