PRODUCT TYPES
 
Special copper alloys
   
  Our company specializes in manufacturing many types of special copper-alloy products. We devote ourselves to research and development of new materials.
   
Metal dies and cavity-molds production
   
  We manufacture cavities made of beryllium copper for dies and molds for precision plastic parts. They are produced through three kinds of casting processes (precision casting, pressure casting and electroforming).
   
Toll processing service
   
  We accept orders from our customers for forging, for instance, as a subcontractor, for those who need dissolving, casting, forging, drawing and heat-treating, etc. as well as machining.
