Step 6: Shell Making After the coating wax patterns, put into the shell-making shop to dry. After taking it out, blow-dry the module with compressed air, and then make a shell by sizing. Immerse the module in cleaning fluid and reciprocate three times, about 4s in total. It can improve the adhesion of making shells. Before making shells and hanging slurry, the wax modules after group number must be cleaned to remove wax crumbs and grease on the surface. Step 5: Wax Pattern Clearing After standing for more than 45min, the wax modules behind group trees can be cleaned. The tree-forming scheme should be carefully considered when designing, and it should be also considered whether the tree-forming scheme is convenient for the recovery and reuse of wax should. The tree-forming scheme determines the yield of products and the utilization rate of molten stainless steel. Generally, 2 ~ 80 wax patterns can be welded on one wax module. Step 4: Tree Assembly After wax pattern repairing, to improve the productivity of qualified wax patterns, a single wax pattern is fused and welded on the pre-made casting system to form a wax pattern assembly.
Meanwhile, inspect the surface quality of each wax pattern, for those wax patterns with burrs, flash, and parting line, they need to be repaired. So, the wax patterns workshop needs to be controlled with constant temperature, minimize the deformation of wax patterns. Step 3: Wax Pattern Reparing The quality of wax patterns will directly determine the quality of final stainless steel castings. Wax pattern can be understood as a die-cast part. Step 2: Wax Pattern Injection Press the treated wax paste into the mold cavity, take it out after the ice water is condensed by the ice water machine, put it into the pool for a period of time, and get a single wax pattern after dressing and inspection. But other stainless steel casting factories just use normal aluminum to save cost. Compared to other suppliers, our foundry selects aviation aluminum as the mold material. Normally, stainless steel casting companies choose aluminum alloy as the mold material. To ensure the quality of wax patterns, the mold must have high dimensional accuracy and a small surface roughness value. They are the same dimensions as final stainless steel castings. The mold used for stainless steel lost wax casting is mainly designed for injecting wax patterns. Step 1: Mold Making After the stainless steel casting design was confirmed, we will start to prepare the stainless steel casting molds. Next, we will introduce our Stainless Steel Lost Wax Casting Process. The Finish And Coating are Natural, Nickel Plated, Electronic Polished Plated, or any coating as per customer specification. And we can produce any special Stainless steel Casting Material Composition as per customers’ requirements. Our main stainless steel casting materials: Stainless Steel SS 304 316 316L 202 Alloys.
We offer Stainless Steel Lost Wax Casting or Stainless Steel investment casting.
So it saves highly cost-effective in many applications. That does not need for secondary operations. Because the wax model that gives shape to the mold is the exact size and shape as the part. Lost wax casting allows for the creation of complex precision parts. There are During the lost wax casting process, the wax molds are melted away.
