In the field of investment casting, QD is an expert in the lost wax casting process. We specialize in providing customized investment casting solutions.

The first step in lost wax casting: drawing design communication

Drawing design is the foundation of casting. QD has established a standardized communication process to ensure that no detail is overlooked:

Lost Wax Casting Step 2: From Wax Pattern to Casting

Once the design is finalized, the core phase of lost wax casting begins. From wax pattern to casting, every step of the process reflects QD’s dedication to precision. The specific process of investment casting is as follows:

Process NameCore FunctionKey Operations
Wax Pattern MakingLay the foundation shape for castingsMake patterns with high-precision equipment according to drawing parameters. Inspect dimensions and finish.
Tree AssemblyOptimize pouring efficiencyWeld wax patterns onto sprue bars as planned. Form wax pattern assemblies.
Multi – layer Shell MakingForm the “mold” for casting formationDip wax pattern assemblies into refractory coating, sprinkle refractory sand. Repeat operations to form multi – layer solid shells.
Dewaxing TreatmentObtain hollow shellsMelt out wax patterns in a high – temperature environment. Retain shell cavities.
Shell BakingImprove shell performanceRemove residual impurities and moisture. Enhance shell strength and air permeability.
Metal PouringComplete casting formationPour molten metal at precise temperature and speed. Cool and solidify.

From the meticulous production of wax patterns to the precise pouring of molten metal. QD fully controls the quality of each process. Ensure process stability throughout.

Lost Wax Casting Step 3: Post-Processing Surface Treatment

After the casting is formed, QD proceeds to the next step: surface treatment. We use multiple processes to enhance the product’s quality and performance. Ensure the casting is in optimal condition:

First, we perform basic cleaning. We remove mold remnants, sprues, risers, and other excess material from the casting surface. Give the casting a clean, initial appearance.

Next, we perform grinding and polishing. Depending on the requirements, we use abrasives of varying grit sizes to finely treat the surface. Achieve a smooth and even finish.

For products with special requirements, we also perform surface strengthening processes:

Finally, our QD team conducts a comprehensive inspection of the surface-treated castings. Ensure that every product meets quality standards.

FAQ

1. What information do I need to provide for investment casting with QD?

You only need to provide a product drawing (or 3D model) and basic information such as the product’s intended use, performance requirements, and dimensions.

2. Is wax pattern making important in investment casting?

Yes. The wax pattern serves as the “prototype” for the casting. Its accuracy directly impacts the quality of the final casting. QD ensures the quality of wax patterns using high-precision equipment and rigorous quality inspections.

3. What effects can casting surface treatment achieve?

Surface treatment can improve the smoothness and corrosion resistance of castings. Sandblasting, electroplating, and other processes can also be used to meet different performance or decorative requirements.

4. How long does it take from drawing consultation to finished product delivery?

The specific timeframe depends on the complexity and requirements of the product. During the initial phase of the collaboration, our technical team will provide a rough estimate based on your drawings.

5. Do you have special performance requirements for your castings? Can QD meet them?

Yes, we can. From the design stage, we’ll recommend the appropriate process based on your performance requirements. We provide customized solution support throughout the entire process.
