QD’s precision casting process and advantages
QD has established a stable, efficient and adaptable precision casting process:
- Mold Design and Manufacturing: 3D modeling is performed based on customer drawings. High-precision molds are customized to mitigate dimensional deviations.
- Investment Casting: High-quality wax is used. Wax patterns are precisely molded through injection molding to ensure accurate reproduction of the original dimensions and details.
- Mold Shell Preparation: Multiple layers of high-temperature refractory materials are applied. The coating thickness is strictly controlled to enhance the mold shell’s strength and air permeability.
- Dewaxing and Firing: After high-temperature dewaxing, calcination is performed to remove impurities and enhance mold shell stability.
- Melting and Pouring: Precisely control the temperature and pouring speed of the molten metal to ensure complete mold filling and minimize defects such as porosity and shrinkage.
- Cleaning and Post-Processing: After de-molding, the casting undergoes fine polishing and flaw detection to ensure surface finish and quality.

FAQ
1. How complex can precision casting produce parts?
We can produce parts with complex cavities, thin walls, and multiple curved surfaces. Parts like turbine blades and special-shaped connectors can all be precisely molded.
2. Is the lead time for precision casting long?
For small batches, the typical delivery time from drawing confirmation is 2-3 weeks; for large batches, production is scheduled in advance. The details depend on the requirements discussed.
3. How do you choose the material? Any recommendations?
Common materials include stainless steel, aluminum alloy, and carbon steel. We will help you select a suitable and economical material based on the part’s application scenario (such as temperature resistance and strength requirements).
4. Can we guarantee surface quality?
Precision castings typically achieve a surface roughness of Ra1.6-3.2μm. They can be subsequently ground and polished to meet appearance and performance requirements.
5. How do you verify casting quality?
We perform dimensional inspection and flaw detection (X-ray and ultrasonic). We can also perform mechanical property testing (tensile strength, hardness, etc.). We have a complete report.
6. Is precision casting significantly more expensive than other casting methods?
For complex, high-precision parts, precision casting saves on subsequent processing costs, offering an overall cost advantage.
For simple, large parts, sand casting is more cost-effective. We will select the appropriate process to control costs.
