Why Choose Us


Equipment Capacity

At present, six automatic double-station core shooting machine sets and two single-station core shooting machine sets are available at Dawang Castings. These machines can produce a variety of castings with an overall dimension of 1000mm x 1000 mm and a unit weight of no more than 100Kg thanks to their 1200mm × 1200 mm maximum tooling installation capacity.

Quality Assurance

Dawang Castings’s first goal is to ensure the products’ quality. We maintained our reputation by providing the best quality products for decades. However, to reduce the impact of human factors and guarantee product consistency, the production process uses a combination of parameterized control and standardized procedures.

Latest Tooling Facility

Dawang Castings continues to invest in cutting-edge technology to produce increasingly complicated parts for its clients. As a result, we can create any casting, even those with intricate moulds. However, the tooling in Dawang Castings is made of high-quality alloy cast iron, which has a small thermal expansion coefficient, small thermal deformation, good strength, and wear resistance, so the accuracy and consistency of the product are well guaranteed.

1. How does investment casting differ from traditional casting methods?

In contrast to conventional sand casting or other casting processes, investment casting places a strong emphasis on detail and accuracy. It employs durable, high-temperature-resistant metal molds that enable the production of thinner, lighter, and more precise components, reducing the need for subsequent machining operations and minimizing material wastage.

2. Why choose investment casting?

Investment casting is highly regarded for its superior surface finish, precise dimensional control, and outstanding mechanical properties. Widely used in industries such as aerospace, automotive manufacturing, medical devices, and energy, precision casting meets the rigorous requirements of applications demanding precision and performance.

3. How is quality ensured in investment casting?

Quality control is paramount throughout the precision casting process. Rigorous material testing, meticulous mold manufacturing, process monitoring during casting, and final product inspections ensure that every casting conforms to design specifications and industry standards. This stringent quality control guarantees product reliability and performance.

4. Is investment casting suitable for my project?

Investment casting is ideal for projects that require high precision and quality castings. If your project involves complex geometries, exceptionally smooth surface finishes, precise dimensional tolerances, or specialized materials, precision casting may be the optimal choice. We can provide customized investment casting solutions tailored to your specific requirements.
