China is a major player in low-pressure casting. To become a leading casting nation, it must address challenges related to resources, energy, human capital, and the environment. High quality and environmental sustainability are the guiding principles for the industry’s development. Accordingly, advanced technologies must be deployed to enhance casting quality and reverse the perception of Chinese castings as low‑tech products in the global market. China’s low-pressure casting sector has entered a new era, presenting promising opportunities for growth. Driven by rapid economic expansion, China has now moved into a phase of high‑quality development, which offers an ideal window for transforming the low-pressure casting industry and ushering it into a stage of sustained, high‑quality advancement.

As China enters the new era, the performance and quality requirements for mechanical equipment are steadily rising, and the standards for low-pressure casting are likewise being elevated. Dimensional accuracy of castings continues to improve, with casting dimensions approaching those of the final parts, thereby reducing the need for subsequent machining. Safety and reliability during service, as well as stringent internal‑quality inspection criteria, have become increasingly demanding. In the design of products such as automobiles and industrial machinery, the demands for overall system performance and weight reduction are growing ever more pronounced.

To elevate the technological level of the low-pressure casting industry, numerous pivotal research efforts have been undertaken in areas such as environmental protection and resource utilization, engineering simulation, informationization, and intelligent manufacturing. Meanwhile, breakthroughs have also been achieved in advanced casting equipment, waste sand treatment, energy-efficient smelting systems, and additive manufacturing technologies for casting.

Current status of the low-pressure casting industry:

1. Talent shortage. In the development of casting technology, China lacks not technology, but skilled personnel. The primary reasons for this brain drain are low wages and poor working conditions at domestic low-pressure casting companies.

2. Small enterprise scale. China has numerous low-pressure casting plants, but most are small in size. Many casting companies are similarly small, with relatively outdated technology, resulting in low labor productivity, substandard product quality, and frequent safety incidents as well as cutthroat competition. These issues hinder the industry’s development.

3. Low employee competence. The majority of workers at Chinese low-pressure casting companies are temporary employees. They have limited education, lack adequate training, and possess poor skills. Consequently, most of those filling these roles are newcomers. While they pay close attention to the production sequence of castings, their understanding of the low-pressure casting process is limited, resulting in subpar product quality and reduced efficiency.

Low-pressure castings feature a dense microstructure, excellent gas tightness, stable dimensional accuracy, and reduced machining requirements, making them well suited for a wide range of sealed, pressure‑bearing components. We offer custom mold development based on your drawings or samples, and can tailor the casting process to meet specific operating conditions. Non‑standard, irregularly shaped parts and special‑specification castings are also available on demand.
