Customizing small gear motors to suit the application of injection molding machines ensures reliable operation.
Gear Motor TA/TR Series
overview
The space inside the injection molding machine is limited, and the nozzle touch mechanism, which presses the nozzle tip against the mold for a tight seal, applies a large reaction force load. Therefore, it was difficult to meet the dimensional and strength requirements of standard specifications.
Therefore, as a customization tailored to the specific application, the output shaft length was adjusted to achieve an optimal layout within the limited space. In addition, a short-time rating specification was adopted to match the operating conditions.
Furthermore, the use of hardened keys provides sufficient strength to withstand reaction loads.
These measures enabled us to create a power source that is suitable for the operating conditions of the injection molding machine.
Problem
The interior of an injection molding machine has limited space, and the equipment had to be fitted to the mounting dimensions specified by the machine itself. In addition, the molding machine uses a "nozzle touch mechanism" that presses the nozzle tip against the mold for a tight seal. Since nozzle touch mainly involves short, repetitive movements, and the reaction force during pressing is concentrated on the shaft and brake hub connection points, there were concerns that the standard specifications would not be suitable in terms of dimensions, operating conditions, and load.
Therefore, customization to match the equipment specifications and operating conditions was necessary.
Adopted products
Gear Motor TA/TR series
This is a parallel-shaft type helical gear reducer.
All models feature silent brakes. We can also manufacture IoT-compatible models with integrated sensors and motors.
It comes pre-filled with grease and is ready to use. There are no restrictions on the mounting direction.
The adoption of an aluminum frame motor has resulted in an even smaller and lighter design. (TA Series)
We can accommodate inverter motors, and we also offer a wide range of optional accessories.

Benefits of adopting the product
As a customization option for Gear Motor applications, the output shaft length is optimized to match the equipment layout.
It can now be installed even in limited spaces.
Furthermore, by adopting a short-time rating specification, performance suitable for the repetitive operation of the nozzle touch mechanism is ensured, resulting in specifications that are appropriate for the application.
Furthermore, by employing a hardened key, the strength of the key section is improved, ensuring a secure connection between the shaft and the brake hub even under conditions where reaction force is applied when the nozzle touches the hub.
This enabled a drive system that is compatible with the operating conditions of the injection molding machine.
