Precision Casting: Efficient and Accurate Processing

Precision casting is a high-precision machining technology that uses casting methods to produce high-quality parts. With the continuous development of industrial technology, traditional machining methods have some problems, such as high processing difficulty and high costs. Therefore, precision casting technology, as an efficient and precise machining method, has received increasing attention.

Principles of Precision Casting

Precision casting technology uses molds to inject molten metal into a mold cavity, then cools and solidifies it to form the desired parts. The principle of precision casting lies in using high temperature and high pressure conditions to melt the metal into a liquid state, then injecting it into the mold cavity with the aid of the mold's shape and structure. After cooling and solidifying, the desired part is obtained. This method can produce parts with complex shapes and avoid defects and deformations that might occur in other machining methods.

Precision Casting Process Flow

The precision casting process flow includes the following steps:

Mold Preparation: Create the corresponding mold based on the shape and size of the desired part.
Material Preparation: Mix and melt the materials in a certain proportion.
Pouring: Inject the molten liquid into the mold via a pouring gate.
Cooling and Solidification: After the liquid cools and solidifies, open the mold and take out the desired part.
Post-Processing: Conduct post-processing on the obtained part, such as deburring and polishing.

Application Fields of Precision Casting

Precision casting technology is widely used in aerospace, automotive, medical devices, electronic products, and other fields. For example, precision casting technology can produce high-precision parts such as aircraft engine impellers, automobile engine parts, and medical devices, showing significant market potential.

Advantages of Precision Casting

Precision casting technology has the following advantages:

Precision casting offers unique design flexibility; complex and precise parts can be cast into shapes close to the final product. It provides almost unlimited freedom with investment casting materials. It is widely adaptable, not limited by the size, thickness, or complexity of the cast part. Symbols such as trademarks, names, or numbers can also be directly cast onto the product.
Various materials can be used for precision casting. These materials include stainless steel, carbon steel, low-carbon alloy steel, copper, aluminum, iron, and cobalt. Therefore, cast parts produced by precision casting can be used in various industries.
Precision casting can be applied in various industries. Mainly used in aerospace, power generation, firearms, automotive, military, commercial, food service, natural gas and oil, and energy industries. Therefore, it can be said that no matter what industry you are in, if your company can benefit from the advantages of precision cast parts and components, they may be the perfect metal choice for all your projects.
Precision casting has stricter tolerances, allowing strict dimensional tolerances as low as ±0.2 mm, thereby achieving high-precision cast parts.
The precision casting process provides superior surface treatment. The required amount of secondary processing and the associated time and cost are reduced. This is sometimes crucial for avoiding mechanical processing or other finishing operations. It can also cast complex text or trademarks externally on the product, reducing the need for later laser marking and engraving.
Precision casting can reduce labor time and delivery time as it greatly minimizes post-casting machining volume. Meanwhile, precision casting can deliver a large number of products in one delivery cycle, which helps customers compete in the market.
Precision casting processes can be used for the production of both small batches and large batches of parts. It offers highly reliable technology and low-cost repeat operations.
The setup cost of precision casting molds is much lower compared to other processes, keeping costs low. Additionally, the near-net shape achieved by precision casting requires little machining, minimizing material waste, reducing energy and material consumption, and mold costs. The initial investment in product development is minimal, making the manufacturing cost very competitive.
Precision casting can provide high-quality products with reduced casting defects. It offers reliable process control, with a much lower scrap rate compared to sand casting.
Precision casting allows for large and small castings. Complex micro parts as small as 30g can be cast, as well as large parts weighing up to 50kg.
