Hydraulic Motor

Product Introduction: High-Quality Mold Hydraulic Motors

In injection molds, die-casting molds, and various automated mold systems, Hydraulic Motors are critical rotary power components that convert hydraulic pressure into mechanical rotational energy. They are essential for applications requiring precise rotational motion such as unscrewing mechanisms for threaded products, rotary core-pulling, mold rotation, and gear-driven ejection systems. As a mold manufacturer that produces for our own use, we maintain extremely stringent standards for torque stability, rotational precision, and durability of hydraulic motors. Every motor undergoes rigorous testing to ensure smooth operation, reliable torque output, and long service life during demanding production cycles.

Self-Produced and Self-Used, Rigorously Selected
We are not only a supplier of mold components but also a mold producer ourselves. Through extensive practical experience in our own molds, we have repeatedly validated the material selection, internal sealing structure, bearing durability, and overall performance of hydraulic motors. Only those with stable torque output, reliable operation, and exceptional durability are approved for our supply system.

Premium Materials, Robust Construction
Our hydraulic motors are manufactured from high-strength alloy steels with precision machined components. Key parts such as the rotor, stator, and valve distribution mechanism undergo specialized heat treatment for enhanced wear resistance. The use of imported shaft seals ensures reliable sealing even under high back pressure conditions, preventing internal leakage and extending motor life.

Precision Engineering, Superior Performance
Hydraulic motors feature precision-matched internal components that deliver smooth rotation across a wide speed range. The low starting pressure design enables quick response and convenient reversing capability. With optimized internal clearances, these motors achieve high mechanical efficiency while maintaining stable output torque from start-up through full operating speed.

Multiple Structure Types, Wide Application Range
We offer various types of hydraulic motors to meet different mold requirements:

• Orbital Motors: These feature a star-shaped inner rotor and outer ring design with advanced valve plate distribution for high mechanical efficiency. Available in BM1, BM2, BM3 series with various mounting flanges, port configurations, and output shaft options. Suitable for unscrewing mechanisms in plastic molds and general rotary applications.

• Radial Piston Motors: Low-speed high-torque design with multiple pistons arranged radially around an eccentric shaft. Ideal for heavy-duty applications requiring high torque at low speeds, such as large mold rotations and core-pulling mechanisms.

• Gear Motors: Compact design with simple construction, good contamination tolerance, and impact resistance. Suitable for high-speed low-torque applications where space is limited.

• Vane Motors: Low inertia, fast response, suitable for high-frequency reversing applications. Compact size and smooth operation make them ideal for precision mold actions.

• Axial Piston Motors: High efficiency, variable displacement options available for applications requiring wide speed and torque ranges. Suitable for demanding continuous operation.

• Torque Output: Continuous torque from 80N·m to over 500N·m, with intermittent torque up to 560N·m

• Speed Range: From low-speed high-torque applications under 200rpm to high-speed applications up to 1200rpm

• Working Pressure: Continuous pressure up to 14-17MPa, with intermittent pressure capability up to 21MPa

• Flow Rate: Optimized flow characteristics for efficient power conversion

Multiple Mounting Configurations, Strong Adaptability
Our hydraulic motors support various mounting styles to accommodate different mold structures:

• Flange mounting (standard square flange, round flange options)

• Foot mounting

• Tapered shaft or keyed shaft connections

• Multiple port locations and thread types (metric, BSP, NPT)

• Custom configurations based on mold requirements

Excellent Sealing, Leak-Proof Performance
High-quality shaft seals and internal sealing components withstand high pressures and temperatures, ensuring long-term leak-free operation. The robust sealing design allows motors to handle high back pressure without external leakage. For applications with back pressure exceeding 3.5MPa, we recommend external drain line connection to optimize performance and extend service life.

Wide Application Range
Hydraulic motors are essential for numerous mold applications:

• Unscrewing Mechanisms: For threaded products such as bottle caps, pipe fittings, and medical closures

• Rotary Core-Pulling: For molds requiring rotating cores to form internal or external threads

• Indexing Tables: For multi-station rotary molds and automated assembly systems

• Gear-Driven Ejection: For synchronized ejection systems requiring rotational motion

• Mold Opening and Closing: For large molds requiring assisted rotary actuation

Easy Installation, Simple Maintenance
Standardized mounting dimensions and shaft configurations ensure compatibility with common mold designs. The modular construction allows for easy installation and maintenance. Multiple porting options provide flexibility for hydraulic circuit integration.

Complete Specifications, Customized Solutions
For standard specifications, we maintain regular inventory of common displacements, mounting types, and shaft configurations for quick dispatch. For non-standard customization, based on your mold structure and application requirements, we offer custom hydraulic motors with special displacements, special shaft configurations, special port locations, and custom mounting flanges.
