Industrial-grade casting solutions engineered for durability and aesthetic perfection.
In the modern construction and industrial landscape, Lost Wax Casting (Investment Casting) has emerged as the gold standard for producing complex architectural hardware. As a premier OEM Architectural Hardware Manufacturer, we recognize that today's procurement demands go beyond mere functionality. Global enterprises now seek "Information Gain"—a deep understanding of material longevity, structural integrity, and aesthetic versatility.
Architectural hardware produced via lost wax casting offers unparalleled surface finish and dimensional accuracy, reducing the need for secondary machining by up to 40%. This efficiency is critical for sectors such as rail transportation, petroleum machinery, and high-end commercial construction.
Founded in 2014 and located in Weifang, Shandong, JUNLONG covers a total area of 60,000 square meters. With an annual production capacity of 20,000 tons of precision castings and machined finished parts, we specialize in high-performance materials including carbon steel, alloy steel, and stainless steel.
Our workforce of over 200 employees, including 30+ senior engineering technicians, ensures we are a high-quality casting supplier integrating precision casting and deep processing.

Full industrial chain integration: Mold manufacturing, Precision Casting, CNC Machining, and Surface Treatment under one roof.
The transition toward Industry 4.0 is reshaping architectural hardware. As a leading manufacturer, our roadmap focuses on three core pillars of innovation:
Utilizing AI to optimize hardware topology, reducing material waste while increasing structural load-bearing capacity for architectural glass clamps and hinges.
Implementing green casting techniques and recycled alloy integration to meet global ESG requirements for "Green Building" hardware certifications.
Developing hardware that integrates IoT sensors for structural health monitoring in large-scale architectural projects and rail systems.
Seamless connection, controllable quality, shorter lead times. From initial design concepts to final product delivery, all key processes are completed in-house:
Customer Value: Eliminates communication costs and quality risks associated with multi-factory collaboration.
Expert insights for technical buyers and procurement managers.
We typically adhere to CT3-CT7 international standards. Our precision casting process ensures that intricate architectural designs maintain tight tolerances, often eliminating the need for expensive secondary finishing.
Every batch of alloy or stainless steel undergoes spectral analysis. Combined with our ISO 9001 and TS 16949 certifications, we provide full material traceability reports required for high-tech infrastructure projects.
Yes. Our engineering team of 30+ technicians specializes in translating complex architectural blueprints into casting-ready molds, supporting rapid prototyping and mass production.
By integrating mold making and machining in-house, we reduce standard lead times by 15-20%. Typical sample development ranges from 3-5 weeks depending on complexity.
