①DesignMost effective design to produce a best quality casting with lowest price.②ModelingAssemble wax/sand patterns into wax/sand custer "tree" to prepare an economic cast mold design.③MoldingA shell is formed with sodium silicate and ludox in a controlled drying room, lost wax inside the mode after it completely dried and solid, then washing and backing the empty shell before pouring. -
④MeltingFast melting, by using the spectrometer to ensure an accurate chemical composition.⑤PouringControl the pouring temperature, speed and time strictly to ensure the best quality effectively.⑥FinshingShell knockout, cutting and surface treatment to achieve a smooth and clean appearance before shipment. -
⑦Heat treatmentDifferent material using different heat treatment process to assure a strong mechanical property, then sand blast and acid passivation after the casting products cooling down.⑧MachiningStrictly control each part's accuracy by most precise machining according to customer's requirements.⑨InspectionInspection in accordance with requirements of customer and the related international standards.
