Weifang, Shandong is a global cluster for precision casting. JUNLONG leverages this ecosystem to offer Full Industrial Chain Integrated Manufacturing. Unlike fragmented suppliers, we provide:
Customer Value: Eliminates communication costs, quality risks, and delays associated with multi-factory collaboration, enabling full-process quality traceability with a single point of responsibility.
In the North American chemical corridor, our 316L valve bodies withstand aggressive acidic environments, preventing leaks in high-stakes processing plants.
Custom cable protectors and valve assemblies for sand-heavy environments, utilizing alloy steels that resist erosion and high-pressure surges.
Providing precision castings for thermal management systems in EV charging infrastructure and hydrogen fuel cell flow plates.
We maintain rigorous standards to ensure our products meet the "Trustworthiness" pillar of E-E-A-T.
Equipped with internationally advanced automated casting production facilities and comprehensive physical and chemical analysis equipment, JUNLONG enhances manufacturing efficiency and product quality stability. Our Machining Workshop includes horizontal and vertical machining centers, CNC lathes, and specialized grinders to provide finished parts ready for assembly.
A: Utilizing investment casting (lost wax) technology, we typically achieve CT5-CT7 linear tolerances according to ISO 8062, ensuring minimal machining allowance and high dimensional stability.
A: Yes, every batch comes with a 3.1 material certificate, including chemical composition and mechanical properties (tensile strength, yield strength, elongation) verified by our in-house spectrometer.
A: We offer Dye Penetrant Testing (PT), Magnetic Particle Inspection (MPI), and X-ray testing (RT) based on customer requirements to ensure the internal integrity of valve bodies destined for high-pressure environments.
A: Standard mold manufacturing takes 3-4 weeks. Sample submission typically occurs within 10 days of mold completion, depending on complexity.
Our company will continue to strengthen research and development efforts for new products and technologies. Strive to become your world-class precision casting supplier.
