The global industrial machinery casting market is currently undergoing a radical transformation. As a premier China casting parts for machinery supplier, JUNLONG Machinery is at the forefront of this evolution. Traditionally, the casting industry was viewed as a labor-intensive sector; however, the integration of AI-driven design, 3D sand printing, and high-precision investment casting (Lost Wax Process) has shifted the paradigm toward high-tech, high-efficiency manufacturing.
In the current geopolitical and economic climate, global manufacturers are seeking "Information Gain"—not just parts, but data-backed reliability. Reliability in machinery components is no longer an option but a requirement for industries such as aerospace, oil & gas, and renewable energy infrastructure. The demand for precision machinery castings in carbon steel, alloy steel, and stainless steel continues to rise as global infrastructure projects demand longer life cycles and higher fatigue resistance.
JUNLONG Machinery Co., Ltd. was founded in 2014. Located in Weifang, Shandong, the company covers a total area of 60,000 square meters and has an annual production capacity of 20,000 tons of precision castings and machined finished parts. It specializes in materials such as carbon steel, alloy steel, and stainless steel.
With over 200 employees, including more than 30 engineering technicians, the company is a high-quality casting supplier integrating precision casting and deep processing. We have obtained ISO 9001, TS 16949, UL, and other quality management system certifications.
Transitioning from manual pouring to fully automated shell-making lines and robotic grinding to ensure +/- 0.1mm tolerance consistency across 10,000+ unit batches.
Utilizing vacuum induction melting and real-time spectral analysis to guarantee chemical composition integrity in alloy steel and stainless steel variants (304, 316, 16Mn).
Implementing closed-loop wax recovery systems and dust extraction technologies to meet the stringent carbon-neutral requirements of European and North American partners.
Every mold is simulated using Magmasoft or ProCAST before production to predict shrinkage porosity and optimize gating systems, reducing waste and lead time.
We do not just sell "metal shapes." We provide structural solutions for the most demanding environments on Earth. Our components are the "backbone" of global industrial progress.
