Industrial-grade investment casting solutions for high-performance applications.
As a global leader in the precision manufacturing sector, China has redefined the standards for Food Grade Stainless Steel Investment Cast Parts. In the modern era of the "Smart Factory" and "Industry 4.0," the demand for hygienic, corrosion-resistant, and high-precision components has skyrocketed. Food-grade casting is no longer just about the alloy; it is about the structural integrity, surface roughness (Ra values), and the absence of micro-porosity where bacteria could thrive.
JUNLONG Machinery Co., Ltd., established in 2014, stands at the forefront of this industrial shift. Our 60,000 square meter facility in Weifang, Shandong, is engineered specifically to meet the rigorous demands of the global food processing and medical industries. By utilizing lost wax investment casting technology, we achieve dimensional tolerances that minimize the need for secondary machining, thereby maintaining the metallurgical properties of the stainless steel surface.
Specializing in AISI 304, 316, and 316L stainless steel. We ensure precise chromium and nickel content to guarantee superior corrosion resistance in acidic or saline food environments.
Our casting processes focus on "Dead-Zone Free" geometry, ensuring that every valve body, pump impeller, or manifold is easy to clean (CIP compatible) and meets FDA standards.
Integrating digital monitoring for wax injection and shell building. Our automated lines ensure that every batch of food-grade parts is consistent in density and finish.

The global food machinery market is projected to grow significantly, driven by automation and safety regulations. China's advantage lies in its Integrated Manufacturing Ecosystem. Unlike fragmented suppliers, JUNLONG provides a "Full Industrial Chain" service—from mold manufacturing and precision casting to advanced CNC machining and surface passivation.
1. Technological Maturity: Chinese factories have transitioned from manual labor to automated precision casting. This reduces human error in the shell-making process, which is critical for complex food-grade valve housings.
2. Supply Chain Resilience: With access to high-quality raw materials and specialized heat treatment facilities within the same industrial cluster, we offer lead times that are 30% faster than European or North American competitors.
3. Certification & Compliance: E-E-A-T principles are at the core of our operations. With ISO 9001, TS 16949, and UL certifications, our parts are ready for immediate integration into global production lines in Germany, the USA, and beyond.
Delivering high-precision stainless steel parts for the world's most demanding environments.
Investment cast 316L pump bodies and tri-clamp fittings that resist "Milk Stone" buildup and withstand aggressive CIP (Clean-in-Place) chemicals.
High-strength, wear-resistant components for grinders and mixers. Our specialized heat treatment ensures long-lasting blade performance.
Ultra-smooth surface finishes (Ra < 0.4μm) achieved through electropolishing, ensuring zero contamination in sterile processing environments.
Answering technical queries for global sourcing managers.
We ensure strict adherence to FDA and EC 1935/2004 regulations. This involves not only the alloy composition but also ensuring no toxic lubricants or residues remain after the casting and machining process.
Our investment casting provides a base Ra of 3.2-6.3. Through secondary CNC machining and precision polishing (mechanical or electrolytic), we can achieve Ra 0.4 or better as required.
Yes. Our engineering team uses advanced simulation software to analyze metal flow and solidification, ensuring that complex geometries are cast without internal defects.
Sample development usually takes 3-4 weeks. Mass production cycles range from 4 to 8 weeks depending on the complexity and volume, with full logistics support to US and EU ports.
From Carbon Steel to Alloy and Food-Grade Stainless Steel.
Our company will continue to strengthen research and development efforts for new products and technologies, integrate advanced management and technical resources, build a powerful brand, and strive to become a world-class precision casting supplier! Whether you need complex valve bodies or durable agricultural components, our team is ready to deliver.
