There are During the lost wax casting process, the wax molds are melted away. It creates a wax mirror surface. Lost wax casting allows for the creation of complex precision parts. Because the wax model that gives shape to the mold is the exact size and shape as the part. It provides a highly accurate part. That does not need for secondary operations. So it saves highly cost-effective in many applications. We offer Stainless Steel Lost Wax Casting or Stainless Steel investment casting.
Our main stainless steel casting materials: Stainless Steel SS 304 316 316L 202 Alloys. And we can produce any special Stainless steel Casting Material Composition as per customers&#; requirements. The Finish And Coating are Natural, Nickel Plated, Electronic Polished Plated, or any coating as per customer specification.
Next, we will introduce our Stainless Steel Lost Wax Casting Process.
After the stainless steel casting design was confirmed, we will start to prepare the stainless steel casting molds.
The mold used for stainless steel lost wax casting is mainly designed for injecting wax patterns. They are the same dimensions as final stainless steel castings. To ensure the quality of wax patterns, the mold must have high dimensional accuracy and a small surface roughness value. Normally, stainless steel casting companies choose aluminum alloy as the mold material. Compared to other suppliers, our foundry selects aviation aluminum as the mold material. But other stainless steel casting factories just use normal aluminum to save cost.
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. Wax pattern can be understood as a die-cast part.
The quality of wax patterns will directly determine the quality of final stainless steel castings. So, the wax patterns workshop needs to be controlled with constant temperature, minimize the deformation of wax patterns. Meanwhile, inspect the surface quality of each wax pattern, for those wax patterns with burrs, flash, and parting line, they need to be repaired.
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. Generally, 2 ~ 80 wax patterns can be welded on one wax module. The tree-forming scheme determines the yield of products and the utilization rate of molten stainless steel. 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.
After standing for more than 45min, the wax modules behind group trees can be cleaned. Before making shells and hanging slurry, the wax modules after group number must be cleaned to remove wax crumbs and grease on the surface. It can improve the adhesion of making shells. Immerse the module in cleaning fluid and reciprocate three times, about 4s in total. After taking it out, blow-dry the module with compressed air, and then make a shell by sizing.
After the coating wax patterns, put into the shell-making shop to dry. The surface layer was dried naturally. But the transition layer and back layer are dried by rotary air drying to speed up the drying. The coating was repeated 5 ~ 7 times (5 ~ 6 layers for small stainless steel castings and 6 ~ 9 layers for large stainless steel castings). Surface layer with fine sand, transition layer sand slightly coarse. After several layers of sand is thicker), until forming a 7 ~ 15mm hard shell. The hard shell has enough strength.
The shell backward into the steam dewaxing ax, melt wax patterns, and outflow from the bottom of the shell. By the water separator separation, the liquid wax can be recyclable. 12 hours later, wax liquid through a filter will be included in the static barrels for 6 ~ 8 hours. Finally, wax liquid into the insulation heat preservation box for second use.
Before pouring, the shell after wax removal should be roasted. The shell should be roasted for 50 minutes in an oil furnace or electric furnace at &#;. The main purpose is to remove the residual wax liquid after wax removal. And to improve the strength and permeability of the shell. To prevent deformation or rupture of the shell during pouring. Another extremely important factor is to reduce the temperature difference between the castable liquid stainless steel and the shell to reduce the shrinkage of the workpiece. When the heat preservation of molten steel is stable and can be poured, the shell which reaches the roasting time in the roasting furnace can be poured. After the casting condenses, the shell is destroyed and the pouring system is removed. Finally, the burr is cleaned and shot blasting is carried out to obtain the target cast stainless steel parts. The surface of stainless steel lost wax castings should be treated by pickling and passivation.

China has been using the 17-4 PH stainless steel lost wax casting process for thousands of years. The casting process is when liquid metal is poured into a mold that contains a three-dimensional impression of the intended shape. The metal is then cooled, and the mold removed leaving the &#;casted&#; metal part.
rn
17-4 PH stainless steel lost wax casting is used for making complex shapes that would not be economical via other methods.
rn
Different casting methods allow for the most economical pricing based on quantities, sizes, materials, and other variables.
rn
Sand casting is for small batches. We can produce these products in small quantities at a low cost. This process allows for small to very large end products. Sand casting also allows most metals to be cast.
rn
Shell molding, also known as shell-mold casting, is an expendable mold casting process that uses resin covered sand to form the mold. It has better dimension control. It is similar to sand casting; the difference is the molding cavity is formed by a hardened shell instead of sand. It uses finer sand mixed with a resin which is molded into a shell. Because the sand is finer and mixed with resin it has a fine surface finish. This process is good for small to medium sized castings made out of cast iron, aluminum, magnesium, and copper alloys.
rn
Investment casting (also known as lost-wax casting in the art world), is the oldest known metal forming technique. This casting process is where the pattern is surrounded with refractory material. The key benefits are versatility, accuracy, repeatability, integrity, and the wax can be reused. It is not as inexpensive as other casting methods; however, it can incorporate intricate contours and the end components are near complete, so they require little or no rework once cast.
rn
Die casting tooling cost is higher than sand or permanent casting, however the part cost is lower. This method forces molten metal under high pressure into the molds (which are machined out of dies). This process is especially good for applications where many small to medium-sized parts are needed with a lot of detail, a fine surface quality, and dimensional consistency is needed.
rn
Permanent mold casting uses reusable molds &#;permanent molds&#;. Common casting metals are aluminum, copper alloys, magnesium tin, zinc, and lead alloys. Permanent molds last more than one casting but still do wear out and need to be replaced with long-runs.
rn
Centrifugal casting is when metal is poured into the mold and allowed to solidify while the mold is rotating. Due to the inertial force, the liquid metal gravitates tow the periphery. This process allows 30 to 50 pieces per hour to be produced, with a batch processing of approximately kg total mass with an average item limit of 2.3 to 4.5 kg.
rn
Continuous casting is for high-volume production. Molten metal is poured into an open-ended, water-cooled mold, which produces a &#;skin&#; of solid metal to form over the liquid center. Gradually solidifying the metal from the outside in. Cast size can range from a few millimeters thick strip to approximately five meters wide strip, or small billets to large slabs. This process is good for steel, copper, aluminum, and lead.
