Edit:Xiangyang Liqiang Machinery Co., Ltd.UpDate:2020-07-27

Wax pressing (wax injection moulding) --- wax repair - wax inspection - group tree (wax module tree) --- shell making (first dip, sand, then paste, finally mold

Shell air-drying) --- dewaxing (steam dewaxing) --- mould shell roasting ---chemical analysis - pouring (pouring molten steel in the mould shell) --- vibration shelling ---

Cutting and separation of casting and pouring rod----Grinding gate---Initial inspection (burr inspection)---Shot blasting---Machining---Polishing---Finished product inspection--- Warehousing

The casting production process is roughly like this. Generally speaking, it can be divided into pressing wax, shell making, pouring, post-processing, and inspection.

Pressing wax includes (pressing wax, repairing wax, group tree)

Wax pressing --- Use wax pressing machine to make wax molds

Repair wax---correct the wax mold

Group tree---group Lamo into tree

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

Pouring includes (baking, chemical analysis, also called spectroscopy, pouring, shell shock, gate cutting, and gate grinding)

Post-processing includes (sand blasting, shot blasting, correction, pickling)

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