Investment casting, often referred to as "lost wax casting," represents the pinnacle of metallurgical precision. In the modern industrial era, this process has transitioned from a traditional craft into a high-tech manufacturing science. Globally, the demand for precision components with complex geometries, tight tolerances, and superior surface finishes has surged, driven by sectors such as aerospace, automotive, energy, and heavy machinery.
As a leading Precision Casting Manufacturer, JUNLONG Machinery Co., Ltd. (founded in 2014) has witnessed the shift towards "Information Gain" in manufacturing—where data-driven process control and material science provide the competitive edge. Our 60,000 m² facility in Shandong serves as a hub for innovation, bridging the gap between raw material integrity and high-performance end-use applications.
Equipped with internationally advanced automated casting production facilities and physical-chemical analysis equipment. We enhance manufacturing stability by meeting rigorous mechanical property requirements for Carbon Steel, Alloy Steel, and Stainless Steel.
Leveraging strong engineering capabilities and a complete quality control system, our products are exported to Germany, the USA, Italy, Canada, and beyond. We are a trusted brand in the mid-to-high-end European and American markets.
Our commitment to quality is backed by ISO 9001, TS 16949, and UL certifications. Every production detail is monitored to ensure high customer satisfaction and process reliability.
Heavy-duty components for excavators and loaders. Our high-chrome alloy steel castings offer unmatched wear resistance in extreme mining environments.
TS 16949 certified parts for braking systems, levers, and powertrain components. High-precision lost wax casting ensures safety-critical reliability.
Valve bodies, pump impellers, and cable centralizers. Our castings withstand high-pressure and corrosive environments in offshore and onshore oilfields.
Core Capabilities: Our workshop features horizontal and vertical machining centers, CNC lathes, and dedicated physical-chemical labs. This ensures that every Custom investment and precision casting project meets the specific metallurgical footprint required by international standards (ASTM, DIN, JIS).
The industry is moving towards Green Casting and Digital Twins. Sustainable manufacturing—reducing waste in the wax recovery process and optimizing thermal energy—is no longer optional. Furthermore, global enterprises are seeking partners who provide "Full-Service Solutions," where the factory isn't just a supplier, but a co-designer who can optimize part weight and strength through generative design and advanced alloy selection.
JUNLONG Machinery is not just a supplier, but a world-class manufacturing partner. Our certifications (ISO 9001, TS 16949) reflect our zero-defect philosophy. Our company continues to strengthen R&D to provide high-quality solutions to global industry leaders.
