Geneva is globally recognized not only as a financial hub and diplomatic capital but also as a critical hub for high-end micro-technology, heavy machinery engineering, scientific research (CERN), and precision manufacturing. Unlike standard industrial regions, the Swiss market requires parts that comply with stringent tolerance requirements and complex metallurgical standards.
Companies operating within Canton of Geneva, Canton of Vaud, and the wider Swiss Plateau need structural elements capable of handling high stress, extreme temperatures, and chemical exposure. From mechanical instruments to transport infrastructure and municipal engineering projects, alloy steel castings provide the mechanical strength and geometric flexibility that raw machining or forging cannot match.
Our casting solutions bridge the gap between high-volume, cost-efficient manufacturing and the uncompromising quality standard demanded by Swiss OEMs, helping you streamline your supply chain without sacrificing technical integrity.
Founded in 2014 and situated in Weifang, Shandong, JUNLONG Machinery Co., Ltd. has established itself as an authoritative manufacturer and exporter of premier carbon steel, alloy steel, and stainless steel investment castings. Covering 60,000 square meters, our facility integrates raw casting and complex multi-axis CNC machining under one roof.
Equipped with automated shell-making lines, professional spectrum analysis equipment, and non-destructive testing (NDT) capabilities, we manufacture components that conform strictly to European standards (EN 10293, DIN 17182). Our focus on mechanical stability and geometric reliability has made us a trusted supplier to buyers across Germany, the USA, Italy, Canada, and Switzerland.
State-of-the-art automated pouring lines ensuring uniform microstructure and zero internal defects.
Why Swiss and global OEMs partner with Junlong Machinery to balance cost and performance.
Unlike Western foundries that outsource machining, we house tooling, investment casting, heat treatment, and precision multi-axis CNC machining within one facility. This vertical integration drastically reduces lead times, prevents quality discrepancies between suppliers, and lowers logistical costs.
Located in Shandong, China's manufacturing heartland, we benefit from stable, cost-effective access to raw alloying elements (Chromium, Molybdenum, Nickel, Manganese). This keeps our base pricing highly competitive and protected against European energy price fluctuations.
We coordinate seamless logistics from our factory in Weifang via Qingdao Port directly to Swiss transport centers or European gateway ports (like Rotterdam or Genoa). We manage all export documentations, customs clearance certificates, and duty processing to ensure hassle-free delivery.
At Junlong Machinery, we maintain a complete quality control system designed to satisfy the rigorous demands of European engineering clients. Every batch of raw materials undergoes optical emission spectrometer testing before pouring to ensure precise alloy composition (e.g., 4140, 20Mn5, 304/316 Stainless Steel).
Our quality management is certified under ISO 9001 and TS 16949, confirming that our processes are standardized to meet automotive safety requirements.
Our facilities are audited by international bodies to guarantee compliance with global regulatory and safety guidelines. We focus on continuous optimization of casting structures, preventing shrinkages, hot tears, and inclusions common in less-regulated foundries.
Precision casting is only the beginning. We deliver completely finished components ready for assembly lines.
Our machine shop handles complex finishing operations to meet tight tolerance demands. We utilize multi-axis horizontal and vertical machining centers, CNC lathes, precision grinders, and heavy-duty drilling machinery. This ensures our castings meet strict assembly dimensions for gearboxes, engines, and heavy structural joints.
To protect components from harsh weather and industrial environments, we offer custom surface treatments, including shot blasting, zinc plating, chemical blackening, powder coating, painting, and hot-dip galvanizing. All treatments comply with environmental regulations (RoHS and REACH).
Developing custom casting formulations for specific industrial applications.
Precision engine brackets, suspension linkages, brake system levers, and structural chassis components designed to withstand cyclic fatigue and mechanical stress.
Heavy-duty connection supports, high-load arm joints, and hydraulic cylinders optimized for digging equipment and cranes working in Alpine conditions.
High-integrity pump valves, chemical piping adapters, and petroleum exploration cable protectors designed for high-pressure and corrosive fluid systems.
The alloy steel casting industry is transitioning toward digital design validation and smarter manufacturing processes. Key trends shaping Swiss and European procurement strategies over the next five years include:
A wide selection of custom industrial castings manufactured to international quality standards.
Medium carbon steel castings offering balanced tensile properties and weldability, widely used in heavy mining assemblies.
Critical brake system components cast under strict quality controls to ensure passenger and transport safety.
Wear-resistant, high-strength structural components designed to handle heavy cyclic loads under long-haul conditions.
Corrosion-resistant steel castings formulated for marine deployments and high-salinity docking applications.
Precision casting blanks cast with complex internal pathways, minimizing secondary machining work.
Components manufactured in our certified automotive-grade lines, guaranteeing batch-to-batch consistency.
Thin-walled, high-strength structural parts designed to improve fuel efficiency without sacrificing crash safety.
Erosion-resistant alloys engineered to withstand severe downhole pressures and chemical degradation.
