Technical Specifications for the Stem Forging Hydraulic Press

The "Stem Forging hydraulic press," developed and manufactured by Jianlong Hydraulic Technology, is specialized equipment designed for the hot, warm, and precision die-forging of aluminum alloy components such as bicycle stems, handlebars, and seat posts. Featuring a highly rigid four-column or frame-type structure and a servo-hydraulic control system, the press enables constant-pressure, constant-displacement, and multi-stage speed control, thereby meeting the demands for high-precision and high-efficiency forging production.
