High-performance components engineered for durability and solar tracking accuracy.
The global shift toward Utility-Scale Solar PV has revolutionized procurement requirements. Modern photovoltaic castings must now support larger modules (600W+) and heavier bifacial glass, demanding increased tensile strength and superior corrosion resistance in desert and coastal environments.
As horizontal single-axis trackers (HSAT) become the industry standard, the demand for precision-cast bearing housings, torque tube connectors, and gear motor mounts has surged. China manufacturers are at the forefront, integrating AI-driven simulation to optimize weight-to-strength ratios.
International procurement now prioritizes "Green Casting." Leading factories are adopting electric induction furnaces and sand reclamation systems to reduce Scope 3 emissions, ensuring compliance with EU Carbon Border Adjustment Mechanism (CBAM) regulations.
The manufacturing of photovoltaic castings involves sophisticated metallurgy. At JUNLONG, we specialize in the following technical routes:
Our Lost Wax Investment Casting technology allows for dimensional tolerances as tight as ISO 8062-3 CT5, reducing the need for secondary machining and lowering the Total Cost of Ownership (TCO) for solar plant developers.
Founded in 2014 and located in Weifang, Shandong, JUNLONG Machinery Co., Ltd. has established itself as a premier global supplier of precision castings. Spanning 60,000 square meters, our facility is engineered for high-volume, high-precision output to meet the rigorous demands of the global energy sector.
Navigating international supply chains with reliability and technical authority.
ISO 9001, TS 16949, and UL certified processes ensure every batch meets global standards.
Seamless delivery to Germany, USA, Italy, and Canada with full customs documentation.
In-house chemical analysis, mechanical property testing, and X-ray flaw detection.
Custom engineering support from 30+ senior technicians for specialized PV projects.
Investment casting (Lost Wax) provides superior surface finish and complex internal geometries that are impossible with sand casting. For solar tracking systems, this means more precise fitment of gears and bearings, leading to less mechanical wear and longer field life.
We utilize specialized alloy steels and stainless steel grades (such as Duplex 2205) combined with advanced surface treatments like hot-dip galvanizing or zinc-nickel plating to ensure a service life of 25+ years, matching the lifecycle of solar panels.
Yes. Our engineering team utilizes 3D-printed wax patterns to provide functional prototypes within 10-15 days, allowing developers to validate new mounting or tracking designs before full-scale tool investment.
For standard casting components, our lead time ranges from 4-6 weeks for production, supported by our 20,000-ton annual capacity which ensures we can scale with your project demands.
Custom lost wax casting for farming equipment, harvesters, and farm vehicles designed for rugged use.
Forging strong mechanical backbones for excavators, loaders, and cranes with high-load bearing components.
High-precision truck brake levers and railway parts meeting TS 16949 automotive quality standards.
Equipped with internationally advanced automated casting production facilities and comprehensive physical and chemical analysis equipment.
