Description

Technical Field

[0001] This utility model relates to the field of precision casting, and in particular to an environmentally friendly precision casting machine tool. Background Technology

[0002] Precision casting, also known as investment casting or lost-wax casting, typically involves creating a pattern from a fusible material, then coating the pattern with several layers of refractory material to form a shell. To remove moisture, residual wax, and saponification from the shell, ensuring low gas evolution and good permeability, while also reducing the temperature difference between the liquid alloy and the shell, and improving filling capacity and casting yield, the shell needs to be preheated before casting. Once preheated, all residual wax inside the shell melts and flows away, leaving only the shell. Molten metal is then poured in through the gating gate, and after cooling, a casting is formed.

[0003] However, the burning process produces a large amount of polluting fumes. If these fumes are not treated and allowed to be emitted, they will have a negative impact on the natural environment.
