Lightweight. Quiet. Powerful.
Plastic gears from Framo Morat
For lightweight, dynamic, and efficient drives, plastics are often the materials of choice: Polymers require only a fraction of the weight of an equivalent metal gear. Plastic gears reduce the moving mass in the drive system, increasing dynamics while reducing energy consumption and wear on bearings and shafts. Thanks to their excellent damping properties, plastic gears can also reduce vibrations and absorb shocks more effectively. As a result, they operate more quietly and have a longer service life.
And these are just the technical advantages: From an economic standpoint, plastic gears are especially appealing for large production volumes since plastic injection molding is faster and more cost-effective than metal machining for serial production. Additionally, the excellent sliding properties of many plastics allow for the design of low-maintenance or even maintenance-free gearing systems.
We have been producing plastic gearing components for more than 60 years, and we are pioneers in precision plastic injection molding. We process engineering thermoplastics, plastics with fillers and reinforcement materials, and high-temperature-resistant materials such as PEEK – enabling us to offer the most suitable material for each application.
Our materials expertise also includes a gear testing rig, where we conduct extensive research on plastic gearing. This gives us in-depth knowledge of the specific advantages and characteristics of each gear type and material. This wealth of experience enables us to develop the ideal solution for your application.
Gear components made of plastic
We develop and manufacture the following gear components for your applications:
Plastic gearing components
Plastic gears from Framo Morat offer you real competitive advantages on the global market. With 60 years of experience in precision plastic injection molding, as well as our own research using an in-house gear testing rig, we have in-depth knowledge of gear geometry characteristics and the behavior of numerous polymer materials under continuous operation and extreme loads. We continuously integrate the findings from these studies into an ever-growing material database.
Based on this knowledge, we can offer you exceptionally lightweight, quiet, durable, and high-performing solutions.
We manufacture spur gears, planetary stages, helical and worm gear sets with straight or helical gearing, as well as internal and external gears. Our range of materials includes engineering thermoplastics such as POM, PA6/66, PA11/12, PA4.6, PBT, PC, PEI, PPA, PPE, PPS, plastics with fillers and reinforcing agents, and high-temperature-resistant materials such as PEEK. Our extensive materials expertise enables us to select precisely the right material for each application.
With module sizes ranging from 0.2 to 4 mm, we provide precise, application-optimized solutions. For example, our plastic gearing components reliably operate under high loads in paper shredders, ensure precise dosing in medical technology, and enable efficient frequency band control in mobile communication antennas.
Your design options:
- Spur gears, planetary stages, helical and worm gear sets
- Spur and helical gears
- Internal and external gearing
- Modules from 0.2 to 4 mm
- Engineering thermoplastics, reinforced plastics, and high-temperature polymers such as PEEK
Hybrid components
Combining multiple materials in one component opens new application possibilities that a single material alone cannot offer – providing powerful, durable, and economical drive solutions for demanding applications.
- The combination of metal and plastic enables gear pairings where the plastic side handles high rotational speeds and converts them into high torque on the metal side.
- In two-component (2K) plastic injection molding, we combine plastics with different strengths and elasticities. This creates gears that combine enormous rigidity with exceptionally smooth operation.
- Shafts that combine metal and fiber-reinforced plastics reduce weight and moments of inertia, thus increasing the efficiency and dynamics of drives.
Plastic housings and technical components
functionality of housings and technical parts: Bearings, axles, and threads made of metal are permanently bonded with the housing's plastic material. Furthermore, through 2-component (2K) plastic injection molding, we can integrate seals made of elastic materials directly during the housing's manufacture.

Partnering with Framo Morat – Your Advantages
Over 60 years of experience in plastic injection molding technology
We are one of the pioneers in precision injection molding, having set the standard for industrial applications for over 60 years. Take advantage of our decades of experience and development expertise for your high-volume, custom-tailored drive solutions!
In-house basic research
Available data on gear-relevant material properties of plastics is still insufficient. That is why we have developed our own gear testing rig to test a wide range of gear geometry and material combinations. This creates a data basis for efficient and reliable development.
Integration with production
We don't just develop gearing components; we also engineer the corresponding injection molds. This allows us to consider injection molding-appropriate component design from the beginning. We consider draft angles and gate locations, as well as warping and shrinkage behavior, right from the development phase.
Possible applications for plastic gearing
In public spaces, in transportation, and in private homes: Plastic gears from Framo Morat can be found almost everywhere. Why don’t you notice them? Because our gears operate so reliably, precisely, and quietly that they go unnoticed.
We understand the specific requirements of each industry and select the appropriate type of gearing: These could be spur or helical plastic gears, bevel gears, or crossed helical plastic gears. We then custom-engineer our gears for the specific application: For electric bike drives, for example, robustness and longevity are the primary focus, while for medical technology, precision and quiet operation are paramount. This is how we create the perfect gear for every application.
Plastic gearing in smart homes
In smart homes, our reliable, maintenance-free, quiet plastic gears power smart thermostats, roller shutter controls, and door locking systems, creating a sense of comfort and security. Our drive components are also present in the world of mobile communications, where they manage and adjust frequencies based on user behavior and network density.
Plastic gearing for electromobility
Plastic gears operate quietly and unobtrusively. Only upon closer inspection do the high demands they must meet become apparent. The advantages of combining metal and plastic are particularly evident in e-bike motors. The high-precision spur gear stage, consisting of a helical rotor shaft made of metal and a plastic gear, delivers weight savings along with smooth, quiet operation and a long service life.
Plastic gearing in smart offices
Ergonomics is becoming increasingly important in modern work environments. The core of the drives for individually height-adjustable desks consists of precise plastic gearing components that reliably convert the drive motor's speed and torque into a smooth, linear lifting motion. Our components are also found in paper shredders: Here, gearing components made from the high-temperature plastic PEEK are frequently used. These components withstand high thermal and mechanical loads.
Plastic gearing for foodservice and culinary applications
In professional coffee machines for the catering industry, our plastic gear components are used in the motorized brewing unit, which consists of the gearbox frame and group head. In household coffee machines, a worm gear-spur gear stage made of plastic is used. The gear set controls the electric valve adjustment for water distribution.
Plastic gearing in medical and rehabilitation device technology
Our stairlift drives control movement, seat swiveling, and tilt correction. Here, the plastic gear with metal insert ensures maximum reliability thanks to its robust connection, precise bearing, and efficient power transmission.
In infusion technology, our gearing components and housing parts enable precise dosing and meet the highest standards for surface quality.
