Welcome to Qiujing Group.

Resin Sand Casting

Utilizing high-quality resin as a binder ensures exceptional mold strength and dimensional stability. This process produces castings with smooth surfaces, clear contours, and dense internal structures, significantly reducing machining allowances. It is the ideal choice for engine blocks, machine beds, and heavy machinery components.

01

Pattern Making & Coating

Foam patterns are made and assembled with the gating system, then coated with refractory material to form a shell.

02

Pouring & Forming

The coated pattern is buried in dry sand and molten metal is poured in. The foam evaporates and the metal solidifies into the final casting.
