• Casting
    Casting is an advanced metal hot-processing technique mastered by human in relatively early period, it is the method to obtain the parts or blank by casting the liquid metal to the casting cavity that is in corresponding shape with the metal parts, which is then cooled down and solidified. The cast material is mostly the metal that is originally solid but is then heated to liquid form, and the mold material can be sand, metal or even ceramic.
  • Silver
    it is a kind of transitional metal. There are its simple substances exist in nature, but it mostly exists in the form of chemical compound in silver ores. The physical and chemical properties of silver are relatively stable, with good thermal and electric conductivity, soft texture, and rich ductility.
  • Tin
    it is a metal element with silver-white luster and low melting point, also a kind of metal with relatively soft texture, its melting point is low, and highly plastic.
  • Copper wire
    it is the wire made of hot-rolled copper rods without being annealed, and can be used for weaving nets, cables, copper brush screens and so on.
  • Enamel
    It is the inorganic glass glaze coated on the surface of metal base. Its production mainly includes glaze preparation, green body preparation, coating, drying, firing, testing and other processes, coat a layer or more layers of enamel in the metal surface, through firing, the two materials enter into both physical and chemical reactions and get firmly combined to form a composite material, which is formerly known as enamel. It combines the strength of the metal and the magnificent appearance of the enamel as well as the resistance to chemical erosion.
  • Cutting and Corrosion
    Cutting happens when the laser beam is irradiated onto the surface of the metal workpiece, the energy released is able to melt and evaporate the metal workpiece so as to achieve the cutting or engraving purposes. Corrosion of metals is the most common form of corrosion. During the corrosion, chemical or electrochemical multi-phase reaction has occurred in the metal surface, the metal enters into the oxidation state.
  • Metal coloring
    Metal coloring roughly consists of three production processes: pretreatment, coloring and post-processing. Pretreatment is to make a smooth and clean surface of the art work through polishing, degreasing, pickling and other methods, which is conducive to the occurrence of coloring reaction; coloring treatment should properly control the concentration of coloring liquid, and the coloring temperature, time and other processing conditions; Post-processing includes drying, painting, etc., painting is usually to apply varnish on the coloring film, which can improve the service life of the coloring film without affecting its appearance.
  • Metal Forming
    This is a processing method to use the plastic deformation capacity of metal materials, under the action of external force, to produce the expected plastic deformation of metal materials, so as to obtain the parts or blank with a certain shape, size and mechanical properties.
