Lost Wax Castings For Marine Double Layer Invisible Locks
Among them, investment casting is more commonly used, also known as lost wax casting: select suitable investment materials (such as paraffin) to make investment patterns; repeat the process of dipping refractory paint and sprinkling refractory sand on the investment pattern, harden the shell and dry; Melt the internal investment pattern to obtain the cavity; roast the shell to obtain sufficient strength and burn off the remaining investment material; pour the required metal material; solidify and cool, and clean the sand after shelling to obtain high Finished product with precision.

Process Flow
Among them, investment casting is more commonly used, also known as lost wax casting: select suitable investment materials (such as paraffin) to make investment patterns; repeat the process of dipping refractory paint and sprinkling refractory sand on the investment pattern, harden the shell and dry; Melt the internal investment pattern to obtain the cavity; roast the shell to obtain sufficient strength and burn off the remaining investment material; pour the required metal material; solidify and cool, and clean the sand after shelling to obtain high Finished product with precision. Depending on the Lost Wax Castings for Marine Double Layer Invisible Locks product requires or undergoes heat treatment with cold work and surface treatment.
Wax pressing (wax injection to make wax molds) --- wax repairing --- wax inspection --- group tree (wax model tree) --- shell making (first dipping, sanding, then dipping, and finally Mold air drying)---dewaxing (steam dewaxing)-------mold roasting--chemical analysis--pouring (pouring molten steel in the mold shell)----vibration shelling--- Cutting and separation of castings and pouring rods----Grinding gate---Initial inspection (raw embryo inspection)---Shot blasting-----Machining-----Polishing---Finished product inspection--- Storage
The casting production process is roughly like this. Generally speaking, it can be divided into wax pressing, shell making, pouring, post-processing, and inspection.
Pressed wax includes (pressed wax, repair wax, and group tree)
Pressed wax---Using a wax press machine to make wax molds
Wax repair --- correct the wax mold
Group tree --- group the wax mold into a tree
Shell making includes (sand hanging, slurry hanging, and air drying)
Pouring includes (roasting, chemical analysis also called spectroscopic, pouring, shell shock, gate cutting, and gate grinding)
Post-processing includes (sandblasting, shot blasting, correction, and pickling)
Inspection includes (wax inspection, initial inspection, intermediate inspection, and finished product inspection)
