To specify appropriate casting method (reisers, chill,
  injection gate, and etc) using structure analysis and
  solidification analysis with reflection on the shape and
  thickness of a product in order to get best quality.
   To make various shaped patterns of core and external
  model with wooden or metal materials according to the
  casting plan.
   To fill the external and internal of the pattern with
  molding sand and harden using the patterns (core,
  external shape, and etc.)
   A groundwork to achieve the required product property
  and determine the product property by eliminating
  impurities and supplement insufficient elements in the
  melting process of scrap iron and etc.
   To flow melt into a mold and harden it into the shape of
  a product
  
   To remove the used sand from the product after the
  melt in the mold is cooled. Then there are the product,
  reisers, and injection gate left only.
   After skakeout, some attachments to the product, such
   reisers, injection gate, and etc., are removed by cutting.
  
   While the segments of products are determined in the
   melting process, the structure of the products still
   remains unstable. To stabilize the structure, the producs
   are kept to be heated in furnace (at 920 ˚C) for some time
   depending on the thickness of the products, so that the
   products acquire mechanical properties.
   Grinding the surface into a shape according to the
   specifications and requirements.
  
   Repairing, welding, and finishing process to get harmful
  defects, detected by visual and nondestructive
  examination, corrected.
   Heat treatment at 600 ˚C to relax the residual stress
   generated in the repairing welding process
  
   Dimensional, visual, and nondestructive inspection in
  the presence of an orderer (to detect internal/external
  mechanical/natural imperfections without destroying or
  damaging a product or material)
   Power Tool or Shot Blast is done to remove scale, rust
   and other deposits on the surface before painting.
   
   Painted according to the customer’s specification.
   
  
   Ship goods by carriers (trailer, or etc.)
