JUNLONG Machinery Co., Ltd., founded in 2014, is a premier high-quality casting supplier integrating precision casting and deep processing. Located in Weifang, Shandong, our 60,000 square meter facility serves as a hub for innovation in carbon steel, alloy steel, and stainless steel manufacturing.
With an annual capacity of 20,000 tons, we specialize in high-tech precision castings for food machinery, automotive, rail transportation, and engineering machinery industries. Our team of 200+ employees, including 30+ specialized engineers, ensures that every component meets the stringent requirements of mid-to-high-end clients in Europe and America.
The global shift toward EHEDG and 3-A Sanitary Standards requires castings with ultra-smooth surface finishes (Ra < 0.8μm) to prevent bacterial growth. Stainless steel 316L and duplex steels are increasingly preferred for their superior corrosion resistance in acidic food environments.
Advanced factories are integrating AI-driven simulation software to predict metal flow and solidification, significantly reducing porosity. Automated shell-making lines and robotic grinding are becoming the benchmark for consistency in food-grade parts.
Modern casting involves closed-loop sand reclamation and energy-efficient induction melting. Global buyers now prioritize suppliers who minimize carbon footprints through "Green Foundry" initiatives.
From mold design to CNC machining and surface treatment, we offer a "one-stop" solution. This eliminates quality risks from multi-factory collaboration.
Equipped with spectrometers, X-ray flaw detection, and CMM (Coordinate Measuring Machines) to ensure 100% compliance with dimensional tolerances.
With exports to Germany, USA, Italy, and Canada, we understand international maritime standards and offer localized compliance support.
Global food processing giants require more than just metal parts; they need resilient supply chains. JUNLONG Machinery addresses this by providing Macro Solutions that include:
Buyers are shifting from "Lowest Price" to "Total Cost of Ownership (TCO)". This includes the cost of quality failure, lead times, and communication overhead. By integrating deep processing, we reduce the buyer's internal logistics complexity by delivering finished, assembly-ready parts.
Our commitment to quality is backed by international standards:
Integration of AI into the wax injection process to reduce shrinkage errors and improve the precision of complex internal cavities in food valves.
Using 3D-printed sand cores and wax patterns to provide rapid prototyping services for custom food machinery orders without high mold costs.
Implementation of "Lights-out" manufacturing in shell-building and pouring stations to ensure peak safety and zero-defect consistency.
