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.

Equipment
Producing investment castings with high complexity and precision requires high-quality equipment that can achieve tight tolerances and repeatable accuracy. At the same time, the production equipment and manufacturing processes must be capable of handling large volumes of products quickly and continuously without compromising product quality. At Haosen Precision Casting, we employ more advanced technologies and equipment at every stage of the investment casting process. Mold design, wax injection, wax pattern assembly, shell preparation, pouring, heat treatment, and testing are all carried out by our highly skilled and experienced team.
Wax pressing
Haosen Precision Casting is equipped with 19 fully automatic and semi-automatic wax injection machines. Among these, there are 11 8T dual-station wax injectors, 1 10T wax injector, 1 16T wax injector, 3 25T wax injectors, 1 30T wax injector, 1 50T wax injector, and 1 80T wax injector, which can meet the molding requirements for products of various sizes.
Shell making
Haosen Precision Casting has two shell-making production lines: a manual shell-making line and an automated shell-making line. The automated shell-making line is equipped with a state-of-the-art three-head, six-arm dipping-and-spraying sand-coating machine that is advanced domestically. This automated production process eliminates the quality variations in mold shells that can occur during manual operations, enhances the stability of the shell-making process, and reduces the physical workload for workers.
Melting and Casting
We have 17 medium-frequency melting furnaces dedicated to the production of steel castings. In addition, we are equipped with two vacuum induction melting furnaces: a single-chamber vacuum furnace with a capacity of 25 kg and a three-chamber vacuum furnace with capacities of 50/100 kg. These vacuum induction melting furnaces can produce nickel-based and cobalt-based investment castings with an equiaxial solidification structure, weighing from 0.03 to 50 kg.
