Shell Molding Manufacture:
Shell mold casting, also known as hot shell mold casting, is a precision casting method bonded by a thermosetting resin mortar. This method first applies an adhesive mortar to the mold shell, and then hardens the mortar by heating to form a shell pattern.
We use it to produce ductile iron, cast carbon, alloy, stainless steel castings, as well as brass and aluminum castings with casting tolerances of ST7...CE8 (ISO 8062) We use this technology by applying pre-coated phenolic resin sand or shell sand.
Advantages of Shell Mold Casting
High detail: Shell mold casting can produce more precise and complex parts than other casting methods, and its dimensional tolerance and surface roughness are better than other casting methods.
Flexible structure: For some parts with complex structures, shell mold casting can simplify the production process and improve production efficiency.
Reduce subsequent processing: Shell mold casting can reduce the amount of subsequent processing of castings, especially precision castings, and some can even be used directly without any processing.
Save raw materials: The shell mold of shell mold casting can be reused, which greatly reduces the cost and time of mold manufacturing. At the same time, shell mold casting sand mold does not require a binder, so it can greatly reduce environmental pollution.
High quality: Shell mold casting uses high-temperature molten metal filling, and shrinks less during cooling, so the internal structure of the casting is uniform and has excellent performance.
Simple equipment: Shell mold casting equipment is simple, with low investment and strong adaptability, especially for small enterprises, it is very suitable.
Wide applicability: Shell mold casting can be used to cast various alloys, including high-bauxite, iron, steel, etc., especially in casting high-bauxite alloys.
