Custom Hydraulic Cylinders for Metallurgical & Heavy Machinery

Tianjin Uranus Hydraulic Machinery Co., Ltd. provides custom hydraulic cylinders for the glass and ceramics manufacturing industry, where high temperatures, abrasive dust, and corrosive chemicals are common. Applications include glass forming machines, press molds, kiln cars, and ceramic press equipment. With over 30 years of experience and recognition as a national small giant enterprise, we design cylinders that can withstand ambient temperatures exceeding 150°C and direct contact with molten glass or glaze. For glass forming (e.g., bottle making), our custom cylinders are used in the gob feeder, press-and-blow, and take-out mechanisms. These cylinders must operate at high speeds (up to 300 cycles per minute) with precise timing. We design them with lightweight pistons, low-friction seals, and high-response valves. The cylinder rod is made from a heat-resistant alloy and is surface-treated to prevent sticking. For a German glass machinery manufacturer, we supplied custom cylinders for an IS machine. The cylinders have a bore of 63 mm, a stroke of 150 mm, and operate at 160 bar. They are equipped with magnetic position sensors and have achieved a service life of 50 million cycles. For ceramic press applications, our custom cylinders generate very high forces (up to 3,000 tons) to compact powder into green tiles. These cylinders are extremely large, with bores up to 600 mm and strokes up to 800 mm. We use forged components, heavy-duty bearings, and high-pressure seals rated for 500 bar. For an Italian ceramic press builder, we provided a custom main cylinder with a built-in load cell and a position sensor for closed-loop force control, ensuring uniform tile density and thickness. For kiln car handling, we supply cylinders that must withstand high radiant heat. We use water-cooled cylinders with stainless steel rods and high-temperature seals. For a Chinese tile manufacturer, we supplied custom pusher cylinders for a roller kiln car system. The cylinders operate in an environment with ambient temperatures of 80-100°C and are exposed to ceramic dust. They feature heavy-duty wipers and external rod scrapers to remove debris. Our manufacturing process for glass and ceramic cylinders includes specialized welding techniques to avoid distortion, heat treatment to relieve stresses, and final testing at elevated temperatures. We provide full documentation, including material certifications, NDT reports, and test logs. Our team is available for on-site support during installation and commissioning.
