Manufacturing Process & Quality Control
After drawings are confirmed, pattern-making will be immediately started according to the drawings at our pattern-making shop.
After CPSS(Casting Process Simulation System) is carried out, sand molds will then be made. The cavity is ensured to be as solid & clean as possible to avoid any possible inclusion.
Raw materials for melting are purchased under high standards. Temperatures are carefully controlled during the whole process to achieve find grain structure for the casting. Samples are taken to verify material analysis and adjust if necessary. Inspected samples will be kept for at least 3 years for traceability.
This process can also be called casting-cleaning. After initial cooling, sandbox will be opened, risers and runners will be removed and the castings be cleaned. Different size castings require different cooling time.
Temperatures are strictly controlled when heating. Spaces between castings will be ensured to allow uniformly heating and fully contact with water when quenching. Quenching operation are carried out within 30 seconds after castings are withdrawn from the oven.
After rectified and polished, Castings will be machined strictly to the drawings for perfect fitment to the machine. Then the QC department will carry out dimensional inspection and submit the dimensional inspection report.
Our foundry has its own phycial and chemical laboratory: German-Made OBLF Direct-Reading Spectrometer; Hardness Testing Equipment; Metallurgical Microscope; Dye Penetrant Inspection Equipment; Dimension Inspection Equipment, etc.
Finished products are packed with steel pallets, convenient for forklift handling, complying with international standards for land, railway, sea and air transportation.
