Industrial Excellence in Stainless Steel & Alloy Castings
Founded in 2014, JUNLONG Machinery Co., Ltd. has emerged as a titan in the precision casting industry. Nestled in Weifang, Shandong, our 60,000 square meter facility serves as the heartbeat of our operations, boasting an annual production capacity of 20,000 tons of precision castings.
Specializing in Food Processing Equipment Cast Parts, we bridge the gap between complex engineering requirements and rigorous food safety standards. Our workforce of over 200 dedicated professionals, including 30+ senior engineers, ensures that every component—from carbon steel to high-grade stainless steel—meets the peak of metallurgical excellence.
In the realm of food processing, material integrity is non-negotiable. We utilize 316L and 304 stainless steel alloys that offer superior resistance to intercrystalline corrosion, especially when exposed to acidic food products or harsh CIP (Clean-In-Place) chemicals. Our casting process ensures a surface roughness (Ra) that prevents bacterial adhesion, aligning with EHEDG and FDA guidelines.
Sourcing from our Weifang factory offers more than just cost efficiency. We provide Vertical Integration: from in-house mold design using CAD/CAM to precision investment casting and advanced CNC machining. This reduces lead times by 30% compared to fragmented supply chains, ensuring "Just-In-Time" delivery for global OEMs in the US, Germany, and Italy.
The food machinery sector is shifting toward Smart Manufacturing. JUNLONG integrates automated wax injection and robotic dipping lines to ensure consistency in complex geometries. This technological edge allows us to produce high-load-bearing components for excavators and agricultural harvesters with the same precision required for delicate food sorters.
Global enterprises today face the challenge of "Local Support vs. Global Scale." JUNLONG addresses this by providing localized technical documentation and compliance support. Whether it's ISO 9001, TS 16949, or UL certifications, our quality control system is designed to act as a seamless extension of your own engineering department. We don't just supply parts; we supply Regulatory Assurance.
Where Precision Meets Reality
Durable lost wax castings for harvesters and farming vehicles, designed to withstand soil abrasion and extreme weather.
High-pressure pump valves and cable protectors for offshore and onshore drilling rigs.
OEM steel castings for brake systems and engine components, ensuring safety and performance.
Custom stainless steel components for mixers, slicers, and bottling lines with sanitary finishes.
Our commitment to quality is backed by international standards. Every batch undergoes rigorous physical and chemical analysis. We utilize spectrometers for material verification and CMM (Coordinate Measuring Machines) for dimensional accuracy.
We strictly recommend 316L Stainless Steel. The addition of molybdenum provides superior resistance to chloride-induced pitting and organic acids found in fruits and processed meats.
We use high-precision aluminum molds and automated slurry coating robots. This removes human error in the "investment" phase, ensuring each casting maintains a tolerance within CT4-CT6 levels.
Yes. Our engineering team utilizes 3D-printed wax patterns for rapid prototyping, allowing clients to test designs before committing to expensive hard-tooling.
Typically, mold creation takes 2-3 weeks, and production takes 4 weeks. With our strategic location near Qingdao port, shipping to Europe or North America adds approximately 4-5 weeks.
