Coated Sand Process
Suitable for manufacturing complex internal cavity blanks; Highly adaptable, capable of producing large and small, simple/complex parts, suitable for mass production, and compatible with steel, iron, and most non-ferrous alloys; Low cost, inexpensive molding materials, and simple processing; Suitable for bucket teeth weighing less than 80kg.
Investment Casting Process
High precision (sizes CT4-6, roughness Ra1.6-3.2μm), minimal machining effort; Suitable for mass production of complex parts from various alloys with good consistency; Suitable for mass production of various models.
Lost Foam Process
Excellent precision and appearance (roughness Ra3.2-12.5μm, sizes CT7-9), machining allowance ≤2mm, reducing processing time by 40%-50%; No parting surfaces or sand cores, capable of casting complex parts without flash or burrs; Binder-free molding sand, with over 95% sand recovery, environmentally friendly and low-cost. Suitable for products weighing 20kg-2 tons.
Forging Process
Eliminates defects such as pores and shrinkage, resulting in dense castings with mechanical properties approaching those of forgings; High dimensional accuracy reduces machining effort; Applicable to a wider range of materials; Easily mechanized and automated, and a process yield exceeding 90%, reducing costs and increasing efficiency.
