The company’s Taicang headquarters is located in the Taicang Economic Development Zone in Jiangsu Province. STOBER also maintains a Beijing location for customer support and commercial activities in China.

The business model is based on modularity. Gear units, motors, feedback systems, controllers, cables, and software can be combined according to the motion requirements of a machine. This allows the same technology platform to serve applications with differing torque, speed, positioning, installation-space, and control requirements.

Products and Technologies

Gear units and gearboxes

STOBER’s mechanical portfolio includes several categories of industrial gear units:

Servo planetary gear units, designed for high positioning accuracy, high torsional stiffness, and low backlash.
Inline planetary gearboxes, used where the motor and driven shaft share a common axis.
Right-angle planetary gear units, suited to compact machine layouts and applications requiring a 90-degree change in the drive path.
Helical and bevel-helical gear units, used for general industrial motion, conveying, and higher-torque applications.
Rack-and-pinion systems, used to convert rotary motor motion into precise linear travel.

Low backlash is particularly relevant in plastics machinery because it supports repeatable positioning, synchronization of machine axes, and stable response during acceleration and deceleration. These characteristics are used in robot axes, mould movement, cutting systems, extrusion auxiliaries, and material-handling equipment.

Motors and integrated motor systems

The company supplies servo motors and related motor-adapter configurations for applications requiring controlled speed, torque, and position. STOBER’s modular design approach permits the combination of gear units with different motor types and, where appropriate, with motors supplied by other manufacturers.

Motor options may be configured with:

High-resolution feedback devices.
Integrated brakes.
Encoderless control in selected applications.
Compact motor-to-gearbox interfaces.
Single-cable connections for motor power and feedback in compatible systems.

These features can reduce installation complexity and help machine builders standardize drive assemblies across different equipment models.

Drive controllers and motion control

STOBER’s electronic portfolio includes drive controllers and motion-control components intended to coordinate motors and gear units within automated machinery. The systems support industrial fieldbus and Ethernet-based communication environments, including interfaces commonly used in machine automation such as EtherCAT, CANopen, PROFIBUS, and PROFINET.

Typical functions include:

Speed, torque, and position control.
Electronic gearing and synchronization.
Multi-axis coordination.
Diagnostic monitoring.
Safety-related drive functions in compatible configurations.
Commissioning and parameter management through software tools.

The combination of controller, motor, and gearbox technology allows the company to provide an integrated drive system rather than an isolated transmission component.

Application-specific performance considerations

Drive selection in plastics processing generally depends on several engineering variables:

Required torque and peak torque.
Operating speed and duty cycle.
Axis inertia and acceleration requirements.
Backlash and positioning accuracy.
Thermal conditions and ambient contamination.
Available installation space.
Required protection rating.
Communication and safety architecture.
Maintenance and lubrication requirements.

For high-dynamic axes, a low-backlash planetary gearbox can provide a rigid connection between the servo motor and the driven mechanism. For conveyors, extruder auxiliaries, and other continuous-duty applications, designers may place greater emphasis on thermal capacity, service life, efficiency, and reliable operation under sustained load.

Applications and End Markets

STOBER products are used across industrial automation sectors in which controlled motion is central to machine performance. In the plastics industry, relevant applications include:

Injection-moulding machine auxiliaries.
Take-out robots and handling systems.
Extrusion line equipment.
Film, sheet, pipe, and profile processing machinery.
Winding and unwinding systems.
Pelletizing and conveying equipment.
Blow-moulding machinery.
Plastics recycling and material-handling systems.
Packaging machines used alongside plastics-processing equipment.

The company also serves:

Machine tools.
Industrial robots.
Packaging machinery.
Semiconductor and electronics production equipment.
Food and beverage machinery.
Warehouse and material-handling systems.
General factory automation.

Plastics machinery often combines repeated high-speed motion with strict requirements for synchronization and repeatability. Drive systems therefore influence not only movement but also productivity, scrap levels, changeover performance, and energy consumption.

Global Presence and Market Position

STOBER Drive Systems Technology (Taicang) is part of an international organization with operations and service partners in more than 40 countries. Company information identifies a worldwide network of subsidiaries and service partners, as well as production and operating locations in Europe, North America, and Asia.

Within China, Taicang provides a strategic base because the Yangtze River Delta is one of the country’s most concentrated regions for plastics machinery, automation equipment, electronics manufacturing, machine tools, and industrial supply chains. The subsidiary is positioned to support both domestic machinery manufacturers and international companies operating production facilities in China.

STOBER competes in a specialized segment of the motion-control market alongside manufacturers of servo gearboxes, precision reducers, industrial gear units, motors, and automation controls. Its differentiation is associated with the integration of mechanical transmission, motors, electronics, software, and engineering support within a modular product architecture.

The company’s market position is therefore tied less to the supply of commodity components than to applications where precision, compactness, dynamic response, engineering compatibility, and lifecycle reliability influence the total performance of the machine.

Research and Development

STOBER’s development activities focus on the convergence of mechanical transmission and electronic control. This reflects a broader industry movement toward integrated mechatronic systems in which a gearbox, motor, feedback device, controller, and software are engineered as a coordinated unit.

Relevant development areas include:

Reduction of mechanical backlash.
Higher torsional stiffness and positioning accuracy.
Compact right-angle and inline drive arrangements.
Improved motor and gearbox integration.
Digital commissioning and diagnostics.
Compatibility with industrial Ethernet systems.
Functional safety for automated machinery.
Energy-efficient drive operation.
Application-specific motion profiles and synchronization.

The company’s long-term development trajectory has moved from gear units and variable-speed drives toward complete drive-system platforms. This trend is particularly significant in plastics machinery, where machine builders increasingly seek standardized platforms that reduce commissioning time and simplify global service.

Sustainability and Environmental Considerations

Drive technology contributes to the environmental performance of plastics machinery through efficiency, durability, controllability, and maintenance requirements. A correctly sized drive can reduce avoidable energy losses, while accurate motion control can improve cycle consistency and reduce rejected parts or material waste.

Relevant sustainability considerations include:

Energy-efficient motors and drive controllers.
High transmission efficiency in appropriately selected gear units.
Long service life and durable mechanical construction.
Maintenance-free or low-maintenance configurations in suitable applications.
Reduced machine downtime and replacement frequency.
Digital control of acceleration, braking, and operating speed.
Potential material savings through improved process repeatability.

The environmental impact of a drive system also depends on the complete machine, operating profile, electricity source, lubrication regime, maintenance practices, and eventual equipment disposal. Consequently, energy efficiency cannot be assessed solely from the gearbox or motor specification.

For the plastics sector, these considerations exist alongside wider pressures to improve resource efficiency, reduce process waste, increase recycling, and comply with evolving energy and environmental requirements. Drive suppliers contribute to those objectives indirectly by enabling more precise and efficient machinery.

Quality Management and Certifications

STOBER’s products are used in industrial applications where dimensional accuracy, repeatability, reliability, and compatibility with automation standards are important. Quality management therefore extends across gear manufacturing, motor integration, electronic control, software, testing, and customer support.

The company presents itself as an established industrial drive manufacturer with a quality-oriented product and service model. Its Chinese exhibitor profile also identifies STOBER Drive Systems Technology (Taicang) as a “Shining Niche” company, a Chinese designation associated with specialized enterprises evaluated according to factors including specialization, operational performance, and management quality.

For machinery manufacturers, practical quality requirements commonly include:

Consistent gear accuracy and backlash.
Verified torque and speed performance.

The company’s modular approach provides a basis for adapting drive systems to different machinery architectures while retaining common components and control principles. Its principal strategic challenge is to maintain technical differentiation in a market where precision drives, servo systems, and automation controls are becoming increasingly interconnected and competitive.

In China, the ability to combine international product development with rapid local application support will remain important. Plastics machinery manufacturers increasingly require not only individual gearboxes or motors but also coordinated solutions that can be integrated into complete machine controls and supported throughout the equipment lifecycle.
