Service industryLiquid measurement and control for oil & gas, food, chemicals, and moreWe have been specializing in precision investment casting of parts for the measurement and control industry for nearly 40 years, offering efficient and highly competitive one-stop solutions that meet the evolving needs of global industry leaders.
High-speed centrifugeThe centrifuge industry demands high product accuracy, superior performance, and complex structural designs. Haosen not only provides customers with manufacturing services but also offers a one-stop solution that includes comprehensive inspections such as dynamic balancing.
Food machineryThe surface of food machinery products must meet the Ra0.4 mirror finish standard. These products are challenging to polish, and after polishing, they must pass a 48-hour neutral salt spray test. Haosen’s customers can rely on us to provide the entire process in-house to meet their requirements.
AerospaceHaosen offers a variety of casting processes and precision machining technologies to produce aerospace components that meet industry standards and customer requirements. We also provide a full range of inspection services to ensure product quality. By offering customers a one-stop solution, we can guarantee competitive product pricing, timely delivery, and high-quality products.

Manufacturing process3D printing3D printing is used in new product development, shortening the R&D cycle and eliminating the need for mold making, thereby ensuring timely delivery for Haosen Precision Casting’s new product development.
Mold manufacturingThe Mold Department is the first step in our company’s product manufacturing process. Currently, the department has 27 employees who are proficient in a full range of processes, including design, process engineering, turning, milling, grinding, CNC machining, three-coordinate measurement, electrical discharge machining (EDM), wire-cutting, precision boring, and fitting work. This enables us to comprehensively handle the entire process—from design to production and assembly of molds and tooling. Our design and machining personnel are highly experienced, each with over 10 years of industry experience. The products we manufacture and produce include: precision casting molds, small stamping dies, rubber molds, plastic molds, part-processing fixtures, measuring tools, as well as molds and tooling for aerospace-related components.
Investment castingInvestment casting is one of the most sophisticated casting processes. While producing parts with intricate structures, it also achieves high dimensional accuracy and excellent surface quality.
Precision machiningPrecision machining encompasses processes such as turning, milling, boring, drilling, electrical discharge machining (EDM), engraving, grinding, and other techniques. It is a process in which material is removed from a workpiece through mechanical operations to produce precision parts that meet stringent dimensional accuracy, geometric tolerances, and high surface quality as specified in the drawings.

Frequently Asked Questions
Frequently Asked Questions
问Precision casting, also known as investment casting.
Castings produced by sand casting often exhibit poorer precision, surface finish, material density, metallographic structure, and mechanical properties. Therefore, when higher performance requirements are needed for castings, other casting methods—such as investment (lost-wax) casting, die casting, low-pressure casting, and others—should be employed. The following is an introduction to these methods, prepared by our company’s editorial team:
Characteristics and advantages of precision casting:
Precision casting, also known as investment casting, has the following characteristics when compared with other casting methods and part-forming techniques:
1. The castings feature high dimensional accuracy and fine surface roughness. The dimensional accuracy of the castings can reach grades 4 to 6, and the surface roughness can be as low as 0.4 to 3.2 μm. This significantly reduces the machining allowance for castings and enables zero-allowance manufacturing, thereby lowering production costs.
2. Castings with complex shapes that are difficult to machine using other methods can be produced. The dimensions of the casting contours range from a few millimeters to over a thousand millimeters, with the thinnest wall thickness as low as 0.5 mm and the smallest hole diameter below 1.0 mm.
3. No restrictions on alloy materials: Precision casting can be used to produce a wide variety of materials, including carbon steel, stainless steel, alloy steel, copper alloys, aluminum alloys, high-temperature alloys, titanium alloys, and precious metals. Precision casting is particularly well-suited for alloy materials that are difficult to forge, weld, or machine.
4. High production flexibility and strong adaptability. It can be used for both large-scale production as well as small-batch or even single-piece production.
In summary, precision casting boasts advantages such as small investment scale, large production capacity, low production costs, simplified processes for complex products, and rapid return on investment. As a result, it enjoys a favorable position in competition with other processes and production methods, and its future prospects are bright.
问What materials are used in precision casting?
What materials are typically used in precision casting?
In precision casting, we can use materials such as stainless steel, carbon steel, and alloy steel—all of which are suitable for precision casting. However, the specific choice ultimately depends on the particular circumstances.
Precision casting, often abbreviated as "precision casting," is a specialized casting method. Generally speaking, parts produced through precision casting do not require further machining, as this process can achieve highly accurate shapes and relatively high casting precision. However, depending on the product requirements, we can also subject these parts to heat treatment and cold working. The main types of precision casting include investment casting and die casting.
