Lost Wax Investment Casting Parts

Investment casting (also known as lost wax investment casting) produces parts with fine detail and an excellent as-cast surface finish. Investment casting produces internal or external features, thin walls, and internal passageways to get to a near-net shape. These features and benefits lead to significant cost savings in material, labor, and machining compared to other metal casting processes.
In investment casting, a detailed wax pattern of the finished part is created and mounted onto a wax "tree" that includes the metal delivery system (gates and risers). Then the tree is alternately dipped into a ceramic slurry and sprinkled with stucco material, and then allowed to dry. This process is repeated until a thick shell exists over the wax pattern.  
The wax pattern is then melted, leaving a cavity within the stucco material in the shape of the pattern. Molten metal is poured into this cavity. Once the metal solidifies the shell is broken away through a shakeout process and the gating material is removed, leaving the finished parts, which are called lost wax investment casting parts.

SHENGFA Hardware is a manufacturer and supplier of lost wax investment casting parts with over 15 years history. These castings are characterized by low surface roughness values and precise tolerances. Lost wax casting is recognized as the highest quality steel casting method available on the market, although it is one oldest manufacturing processes in history. There are a wide variety of parts, products, and components produced using lost wax casting or investment casting. The precision and accuracy of the processes have made them an ideal method for producing parts with thin walls, intricate details, and close tolerances. A high percentage of lost wax investment casting parts are general hardware, such as brackets, valves, and pump parts.

*External shaping and tight tolerances exist
*Parts are shaped or non-symmetrical with fine detail
*Multiple and/or intricate internal passageways in design
*Excellent as-cast surface finish is required
*Wall thickness is too thin for sand casting
*High upfront tooling costs relative to sand casting are acceptable
*Low volume allows printed patterns to replace upfront tooling
*Ongoing tool maintenance costs are not desired
*Machining of internal passageways is not possible
