Resin Sand Casting

Forming process where a sand mold made of resin-bonded sand used to create a molded product. Resin binders are natural or synthetic high melting point gums. Compared with conventional sand mold, resin sand can be packed more tightly giving it higher strength. Thus one can maintain higher tolerances accuracy and larger casting.

Step 1

Tooling Design and Tooling Making

Designing and making cope pattern plate, drag pattern plate and core box.

Step 2

Preparing Resin Sand For Molding

Mixing resin with sand.

Step 3

Core halves pasted together

Making the cores in core box and pasted cores together.

Step 4

Molding Cope

Packing the resin sand around the cope pattern plate, sprue and risers. Then remove the extra sand, pattern, sprue and risers.

Step 5

Molding Drag

Packing the resin sand around the drag pattern plate. Then remove the extra sand and pattern.

Step 6

Core Setting

Setting core in the drag.

Step 7

Cope and Drag Assembly

Assembled cope on the top of drag and securely clamped them together.

Step 8

Casting

Molten metal is poured into the resin sand mold.

Step 9

Sand Removal

Casting is removed from resin sand mold. Shakeout the core and resin sand from casting.

Step 10

Cut Off

Cutting sprue and risers on casting.

Step 11

Heat Treatment

Finished parts are heat treated to desire hardness as requested.

Step 12

Shot Blasting

Removed extra residual material on the casting surface and stress release casting stress that create during the casting process.

Step 13

Final Inspection

Castings undergo thorough testing and inspection to ensure that they meet dimension tolerances and specifications.
