Lost Foam Process

The problem

Cores, parting lines and draft eat machining stock on boxed geometries.

What Jianheng does

Pattern, coating, sand fill, vibration and pouring as one package. Original cases: grate bar, motor body, pipe fitting, machine tool, wear parts, shell body.

Fits

Medium-complexity iron and steel where eliminating cores pays for the foam shop.

Usually the wrong answer when

Ultra-high volume small parts already on a flaskless cell.
