Custom Hydraulic Cylinders for Metallurgical & Heavy Machinery

Tianjin Uranus Hydraulic Machinery Co., Ltd. provides custom hydraulic cylinders for the food and beverage processing industry, where hygiene, corrosion resistance, and washdown capability are essential. Applications include filling machines, sealing equipment, presses for juice extraction, and conveyor systems. As a national intellectual property advantage enterprise with over 30 years of experience, we design cylinders that comply with FDA and EC 1935/2004 requirements for food contact materials. Our custom cylinders for filling machines must operate with high speed and precision, and they must be easy to clean. We use 316L stainless steel for all external surfaces, with a polished finish to prevent bacterial growth. The seals are made from FDA-approved materials such as EPDM or PTFE. For a German filling machine manufacturer, we supplied custom cylinders for a rotary filler used for beverages. The cylinders have a bore of 40 mm, a stroke of 80 mm, and operate at 100 cycles per minute. They are designed for CIP (clean-in-place) cleaning and have IP69K protection. For juice extraction presses, we provide large custom cylinders that apply high pressure to fruit or vegetable pulp. These cylinders must be resistant to acidic fruit juices. We use stainless steel 304 or 316 for the wetted parts, and we offer a special coating for the rod to resist pitting. For a US-based juice producer, we supplied a custom main cylinder for a 100-ton apple press. The cylinder has a bore of 250 mm and a stroke of 600 mm, operating at 200 bar. It has been in service for over 10 years with no corrosion issues. For food packaging equipment, such as tray sealers and vacuum packers, we provide compact custom cylinders with integrated valves to simplify the machine design. We offer cylinders with sanitary fittings and smooth, crevice-free surfaces. For a Chinese food packaging machinery builder, we supplied custom cylinders for a thermoforming packaging machine. The cylinders have a bore of 32 mm and a stroke of 150 mm, and they use food-grade hydraulic oil. Our manufacturing process for food industry cylinders includes passivation of stainless steel surfaces, surface roughness testing, and functional testing with food-grade fluids. We provide FDA conformity declarations and material certifications. For a custom cylinder for your food and beverage application and a quote, please contact us.
