Wax pressing (wax injection molding) - wax repair - wax inspection - tree assembly (wax module tree) - shell making (first dip, sand pouring, then dip, and finally air dry the shell) - dewaxing (steam dewaxing) - shell baking - chemical analysis - pouring (pouring steel water in the shell) - vibration shelling - cutting and separation of casting and pouring bar - grinding gate - initial inspection (maoembryo inspection) - shot blasting cleaning - machining Engineering - polishing - finished product inspection - Warehousing

Generally speaking, casting production process can be divided into pressing wax, shell making, pouring, post-treatment and inspection

Wax pressing includes (wax pressing, wax repairing and tree forming)

Wax pressing - making wax mould with wax pressing machine

Wax repair - modification of wax mold

Group tree - group wax mould into tree

Shell making includes (sand hanging, slurry hanging and air drying)

Pouring includes (baking, chemical analysis is also called spectrum, pouring, vibrating shell, cutting gate, grinding gate)

After treatment (sandblasting, shot blasting, correction, pickling)

Inspection includes (wax inspection, initial inspection, intermediate inspection and finished product inspection)
