Shell Molding Casting Process in China

Shell mold casting also known as the shell molding process,which can produces high-quality castings for gray iron and steel parts,as a high precision casting process,shell casting uses resin-coated sand as the core material and forms,produce complex metal parts through thin-shell molds.

Shell Molding mostly use the resin sand as the raw material,only resin sand is yellow and very fine,When heated against the metal pattern,the resin-coated sand cures to form a rigid shell or core.

The shell molding can make the good surface quality,precise tolerances and thin wall thinkness.Shell molding achieves dimensional tolerances slightly below those of lost wax investment casting, yet significantly tighter than green sand and conventional resin sand casting processes.If you have the high requirements to your products,no matter it is the size or weight of the parts,we suggest you choose the shell molding to produce these parts,of course,we also provide the custom-made services as well,you only need send the drawing or sample to me first,we will help you confirm the production process and prices.

However,Shell molding must to make the metal mold,we can not use the wooden material or 3D print mold to instead metal mold,the cost of metal molds is high,the currently casting cost about 1.3-1.6 usd/kg,It mainly depends on the weight and complexity of the part.Comparatively, meeting delivery deadlines for shell molding casting poses a challenge to suppliers,if our annual demand is large,such as 20,000 pieces one year,you should verify and confirm the delivery capability from your suppliers.Do they have sufficient shell-type machines?it will be important for you.I would recommend that you also consider production via a molding line as an alternative to shell molding casting; our molding machines offer the opportunity to achieve this replacement.Both the mold price and the casting price will be low,what is more,the delivery time will be significantly shortened.

For the shell molding,there is no weight limit when produuce,it even can produce the min weight 0.1 kg,no other production process can achieve this.Shell castings not only work for cast iron materials,it also suitable for different steel material,this will widen its field of application.
