This shooting cylinder (injection unit traverse cylinder) is the core actuator of the injection unit movement system in injection molding machines. Mounted between the injection unit carriage and the machine frame rails, it hydraulically advances and retracts the entire injection unit, enabling precise engagement and disengagement of the nozzle with the mold sprue bushing. During injection, the cylinder firmly holds the unit forward, maintaining a tight nozzle-sprue seal to prevent melt leakage; during plastication pauses or shutdowns, it retracts the unit for purging, color changes, or mold maintenance. A compact double-acting design with a maximum thrust of 384 kN, combined with a special low-friction sealing system, anti-pressure-trap drain ports, and a long-life surface-treated piston rod, delivers precise, smooth, leak-free injection unit movement control under high-frequency cycling, rapid response, and continuous production. It is a key guarantee for stable injection in high-speed precision molding machines.

This ejection cylinder is the core actuator of the mold ejection system in injection molding machines. Mounted on the rear side of the moving platen, it hydraulically extends its piston rod to drive the ejector plate, smoothly pushing the finished part out of the mold cavity. A multi-force design with a maximum thrust of 760 kN, combined with a special low-friction sealing system, anti-pressure-trap drain ports, and a long-life surface-treated piston rod, delivers precise, leak-free, low-film ejection motion under high-frequency cycling, rapid retraction, and continuous production. It is a key guarantee for efficient, stable part demolding in high-speed precision injection molding machines.

This mold opening and closing cylinder is the core power element of the clamping unit in injection molding machines. Mounted between the machine’s fixed platen and the moving platen, it hydraulically extends and retracts its piston rod at high frequency to rapidly close and lock the mold halves, or open them for part ejection — completing the injection, holding, cooling, and demolding cycle. A compact, double-acting heavy-duty design with a maximum thrust of 384 kN, combined with a special low-friction sealing system, anti-pressure-trap drain ports, and a long-life surface-treated piston rod, delivers smooth, precise, leak-free clamping motion under high-frequency reciprocation, rapid response, and continuous production. It is a key guarantee for the efficient and stable operation of high-speed precision injection molding machines.

This mold transfer cylinder (reciprocating cylinder) is the core actuator for rapid mold changing and multi-station switching in injection molding machines. Mounted on the machine’s transfer carriage or rotary table, it hydraulically extends and retracts its piston rod at high speed to shuttle the mold from the clamping station to the injection station, or to alternate between two mold halves. A long-stroke, low-pressure high-flow design with a maximum stroke of 4,000 mm, combined with a special low-friction sealing system and anti-pressure-trap drain ports, delivers smooth, low-film, leak-free high-speed mold transfer even under high-frequency reciprocation, fast cycling, and continuous production. It significantly shortens mold-change time and boosts the overall productivity of injection molding machines.
