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.

问What exactly are instruments and meters?
问Precision Casting Technology Requirements
For example, in precision sand-mold casting, factories engaged in mass production should create conditions for adopting technologically advanced molding and core-making methods. Older-style shake-type or vibration-pressure molding machine production lines have insufficient productivity, involve high labor intensity for workers, generate significant noise, and are therefore ill-suited to the demands of mass production; thus, they should be gradually upgraded. For small castings, horizontal-parting or vertical-parting boxless high-pressure molding machine production lines can be used—these offer high production efficiency and occupy a relatively small footprint. For medium-sized castings, various box-type high-pressure molding machine production lines and air-impulse molding lines can be selected to meet the requirements of rapid, high-precision molding. As for core-making methods, highly efficient techniques such as cold-box cores, hot-box cores, and shell cores can be employed.
For medium-batch large castings, resin self-hardening sand molding and core making can be considered.
For heavy castings produced in small batches and single pieces, manual molding remains an important method. Manual molding is highly flexible and can accommodate a wide range of complex requirements without demanding extensive process equipment. It can utilize various types of molds, including water-glass sand molds, VRH-process water-glass sand molds, organic ester water-glass self-hardening sand molds, clay dry molds, resin self-hardening sand molds, and cement sand molds. For heavy castings produced in single-piece quantities, the pit-mold casting method offers low costs and rapid production start-up.
For standardized products manufactured in large batches or for long-term production, the multi-box molding and split-box molding methods are particularly suitable. Although initial investments in molds and sand boxes are relatively high, these costs can be offset by savings in molding labor time and improvements in product quality. Casting methods such as low-pressure casting, die casting, and centrifugal casting, due to the high cost of equipment and molds, are best suited for mass production only. As for specific casting conditions, take, for example, the production of large machine tool beds: generally, the group-core molding method is employed, eliminating the need to fabricate patterns or sand boxes and instead assembling the core directly in an excavation pit. In contrast, another factory might opt for the sand-box molding method, fabricating patterns separately.
Different enterprises have varying production conditions—including equipment, facilities, and employee qualifications—as well as distinct production practices and accumulated experience. Therefore, when selecting products to manufacture, it’s essential to take these conditions into account and determine which products are suitable and which are not (or cannot be) produced. The precision requirements and costs differ depending on the casting method used; likewise, initial investment and productivity levels vary, leading to differences in overall economic benefits. To achieve high volume, speed, quality, and cost-effectiveness, it’s crucial to consider all these factors comprehensively. Before finalizing a casting method, conduct a preliminary cost estimation to identify the method that offers the highest economic returns while still meeting the required specifications for the castings.
问Comparative Characteristics of Precision Casting Methods
Precision casting employs specific methods, and this is a crucial question. Additionally, we can gain insight into specialized processing techniques and the distinctive features that are particularly relevant to precision casting—these are the primary approaches we use for detailed decomposition and casting. The construction and discovery of these forms enable us to develop a range of product strategies at a certain level. To this end, we must adopt a complementary approach that leverages our respective strengths to formulate rational strategies tailored to the unique performance characteristics of precision casting. In terms of general-level complexity and advantages, the continuous processing allows us to develop casting forms and features in an unconventional manner. Thus, we are compelled to employ novel methodologies and specific conceptual frameworks to provide appropriate explanations and clarify common casting scenarios. These approaches represent a level of detail and variety that goes beyond typical precision-casting practices. Such changes allow our casting types to maintain both scalability and potential for further exploration. Moreover, the resulting coatings should highlight the specific characteristics we possess, and our manufacturing scales, while expanding, also exhibit a degree of harmonious adaptability. To a large extent, the classification of characteristics we require is characterized by non-definitional expansion and general follow-up exploration—a fundamental feature we consistently uphold.
The key adjustment method in precision casting is our focus on distributed measurement, which also highlights the advantageous nature of our position in tackling a significant challenge. At the precision level, what we should pay attention to is using appropriate core-pulling mechanisms tailored to different product structural types—only such products meet our customers’ needs.
