In the global food and beverage industry, the integrity of equipment components is paramount. Food-grade casting parts are not merely mechanical components; they are the frontline of hygiene defense. As a premier custom food grade casting parts factory, we understand that "food grade" implies more than just stainless steel. It involves strict control over surface roughness (Ra values), non-porous structural integrity, and resistance to aggressive Clean-in-Place (CIP) chemicals.
Modern food processing requires components that can withstand extreme temperatures, high pressures, and corrosive environments without leaching harmful substances into the product stream. From dairy processing to meat packaging, our precision casting solutions leverage the latest "Lost Wax" technology to provide seamless, smooth-surface components that eliminate bacterial growth pockets.
Specializing in AISI 304, 316L, and Duplex Stainless Steels to ensure zero contamination and high corrosion resistance in acidic or saline food environments.
Utilizing automated grinding and electrolytic polishing to achieve Ra values below 0.8μm, meeting international sanitary standards for food contact.
Full heat number tracking and chemical composition analysis (Spectrometer) for every batch, ensuring each part meets FDA and NSF guidelines.
JUNLONG Machinery Co., Ltd., founded in 2014, has evolved into a global leader in precision investment casting. Located in Weifang, Shandong, our 60,000 square meter facility produces 20,000 tons of high-performance castings annually. We don't just supply parts; we provide engineered solutions across carbon steel, alloy steel, and stainless steel.
Our location in the Shandong manufacturing hub allows for immediate access to high-grade raw materials and a network of specialized surface treatment partners, significantly reducing lead times for global procurement.
We are integrating AI in mold design and simulation to predict casting defects before pouring, ensuring a near-zero scrap rate for complex food-grade valve housings and pump impellers.
The industry trend is shifting towards sustainability. Junlong is investing in energy-efficient induction furnaces and waste sand recycling systems to meet the "Green Supply Chain" requirements of Fortune 500 clients.
The "China Advantage" has transitioned from simple cost-efficiency to technical sophistication. Global enterprises now seek partners like Junlong for our ability to handle low-volume high-mix (LVHM) production while maintaining rigorous ISO and TS standards. Our engineering team of over 30 technicians provides proactive design feedback (DFM), helping international clients optimize part weight and reduce secondary machining costs.
From the fields to the pharmacy, our castings are everywhere.
Heavy-duty tillage and harvesting components that withstand high-impact soil contact and moisture exposure.
High-pressure valve bodies and drilling equipment parts optimized for extreme heat and corrosive chemical environments.
TS 16949 certified precision components for engines, brackets, and suspension systems ensuring road safety.
Strong mechanical backbones for excavators and loaders, designed for extreme load-bearing conditions.
Our company has obtained ISO 9001, TS 16949, and UL certifications. This ensures process control over every production detail, from the wax injection to the final non-destructive testing (NDT).
Equipped with internationally advanced automated casting facilities and comprehensive physical and chemical analysis equipment:
Choosing the right alloy is the most critical decision in procurement. While 304 stainless steel is the standard, 316L (Low Carbon) is the preferred choice for food grade casting parts involving high salinity (brine) or high acidity (citrus processing). The addition of Molybdenum in 316L significantly improves resistance to pitting and crevice corrosion.
Sand casting, while cheaper, often results in a surface porosity that can harbor pathogens. Our investment casting (Lost Wax) process provides a superior surface finish (as-cast Ra 3.2 or better) and tighter tolerances (+/- 0.1mm), which reduces the need for expensive post-machining. This "Near-Net-Shape" manufacturing is the global gold standard for food-safe pumps, valve handles, and manifold systems.
With an annual capacity of 20,000 tons, Junlong Machinery utilizes robotic shell-building lines. This automation ensures consistency across thousands of parts—a critical requirement for global OEMs who need their components to fit perfectly on automated assembly lines in Germany, the USA, or Canada.
We are ISO 9001 and TS 16949 certified. Our materials comply with FDA and NSF standards for food contact, and we provide material test reports (MTRs) with every shipment.
Yes. We have a team of 30+ engineering technicians who work with Pro/E, SolidWorks, and AutoCad to turn your 3D models or samples into high-precision castings.
Generally, mold manufacturing takes 2-3 weeks, followed by sample production. Once approved, mass production typically takes 4-6 weeks depending on volume and complexity.
Absolutely. We have a full machining workshop with CNC lathes, milling machines, and grinders, plus surface treatments like pickling, passivation, and electropolishing.
We use simulation software to optimize the gating system and utilize X-ray and ultrasonic testing for internal integrity assurance.
Our high-tech precision castings are exported worldwide, including the United States, Germany, Italy, Canada, and various other European markets.
Our company will continue to strengthen research and development efforts for new products and technologies, integrate advanced management and technical resources, and strive to become your world-class precision casting partner!
