In the modern industrial paradigm, food grade investment casting has transitioned from a simple component supply process to a critical pillar of global food safety and supply chain resilience. As regulatory bodies like the FDA (USA) and EFSA (EU) tighten standards on "Food Contact Materials" (FCM), procurement officers are increasingly seeking partners who offer more than just metal shaping—they require material science expertise and total traceability.
Major enterprises in the US, Germany, and Italy are pivoting toward "Quality-First" sourcing. The demand for 316L stainless steel components with ultra-low Ra (surface roughness) values is at an all-time high, driven by the need to eliminate bacterial harborage in automated food processing lines.
JUNLONG Machinery addresses the macro-industrial challenge of lead-time volatility. By integrating mold design, casting, and deep machining in one 60,000 m² facility, we mitigate the risks of cross-border logistics and multi-vendor quality drift.
Future-proof casting involves energy-efficient induction melting and recyclable wax patterns. Our technical roadmap prioritizes a reduced carbon footprint, aligning with the green procurement mandates of Fortune 500 food equipment suppliers.
Founded in 2014 and headquartered in the industrial hub of Weifang, Shandong, JUNLONG Machinery Co., Ltd. has emerged as a global leader in high-performance metallurgy. With an annual production capacity of 20,000 tons, we bridge the gap between complex engineering concepts and finished, market-ready precision components.
Our workforce of over 200 dedicated professionals, including 30+ senior engineers, specializes in transforming carbon steel, alloy steel, and high-grade stainless steel into mission-critical hardware for the world’s most demanding industries.

Investment casting (lost wax casting) for food equipment demands a level of precision that traditional sand casting cannot achieve. At JUNLONG, we employ a Technical Roadmap focused on three core pillars: Dimensional Stability, Metallurgical Purity, and Surface Integrity.
Utilization of premium CF8M (316) and CF8 (304) stainless steels, ensuring maximum corrosion resistance against acidic food products and caustic cleaning agents (CIP processes).
Equipped with internationally advanced automated production facilities, we enhance manufacturing efficiency while maintaining absolute consistency across high-volume production runs.
Our castings are engineered to eliminate "dead zones." By achieving smooth internal radii through precision molding, we help our clients meet the strict 3-A Sanitary Standards.
We provide full-process machining from rough blanks to precision components using our comprehensive workshop:
In the food equipment industry, a supplier’s credibility is defined by their certifications and quality control systems. JUNLONG is not just a manufacturer; we are a certified partner in safety.
Global standard for quality management systems ensuring consistent product excellence.
High-level quality system originally for automotive but applied to our rigorous food-grade processes.
Safety compliance for international markets, confirming our commitment to global standards.
Our "Full Industrial Chain Integrated Manufacturing" approach means Mold Manufacturing -> Casting -> Machining -> Surface Treatment are all handled under one roof, providing a single point of responsibility and full quality traceability.
Robust components for farming equipment, harvesters, and farm vehicles designed for extreme durability.
Precision-cast engine brackets and structural parts for high-load transportation systems.
Wear-resistant components for excavators and loaders, forging strong mechanical backbones.
One of the most critical aspects of food grade investment casting is achieving a surface finish that prevents biofilm formation. Unlike traditional machining of solid blocks, our lost-wax process allows for complex internal geometries to be cast with a surface smoothness often exceeding 125 Ra (micro-inches). For ultra-hygienic applications, our secondary polishing and electropolishing services can reach finishes as low as 10-20 Ra.
The industry is moving toward "Digital Metallurgy." JUNLONG is integrating AI-driven simulation software to predict metal flow and solidification, eliminating internal porosity before the first drop of metal is poured. This proactive engineering approach ensures that food equipment manufacturers receive parts that can withstand decades of high-pressure washdowns and thermal cycling.
Exporting to Germany, the USA, Italy, and Canada, JUNLONG understands the nuances of international trade. We provide DDP (Delivered Duty Paid) options and localized logistical support to ensure our food-grade components arrive on your assembly line without regulatory or customs delays.
