Plastic gears
Customized plastic gear wheels made to measure
Even a small cogwheel can determine whether a machine works properly or not. If the cogwheel in the gearbox is missing, production comes to a standstill – what now?
At Wefapress® we understand that each project is unique and has specific requirements. That is why we offer Individually manufactured plastic gear wheels tailored to the specific needs of each customer. Our gears are not mass-produced, but made to measureto ensure high quality and performance. That is why we also offer No minimum order quantity – we can also supply you with the required gears in small quantities or as one-off production.
Unlimited possibilities through plastic machining
Thanks to the large number of different material qualities and the almost unlimited possibilities offered by plastic machining, we can produce a wide range of gears and gear segments. Whether cylindrical gears, internal gears, helical gears, worm gears, sprockets, splined shafts, helical gears, special gears or racks – we have the solution for you.
Procedure: What is the individual production of plastic gears?
In contrast to mass production using an injection molding process, at Wefapress® we attach great importance to the possibility of individual production of gears according to your personal wishes and specifications.
The manufacturing process for plastic gears is as follows:
Step 1
If you are interested, please send us an inquiry including an idea, sketch or technical drawing of the desired gear, the required quantity and the preferred material.
Step 2
We check your inquiry for feasibility and, if necessary, discuss technical features, optimization options or material selection. We will then send you the corresponding offer for the order.
Step 3
After acceptance of the offer by you Wefapress® manufactures the gear wheel. Your drawing and any special features discussed for production in accordance with DIN ISO 2768 form the basis for this. The gear is then manufactured from the semi-finished product using a CNC program, special tools and the expertise our employees have acquired over the years on modern machinery for machining plastics.
Inspections during production and a final inspection ensure proper manufacture.
We also offer the following services as part of the individual production of plastic gears:
✓ Free advice
✓ Material selection and free material samples
✓ Advice on plastic-compatible designs and production processes
✓ Worldwide delivery by appointment
Product details for our made-to-measure plastic gears
Properties of the plastic gears
You can obtain plastic gears from us in various materials, for example you can choose between different thermoplastics such as PE-UHMW / St 1000®, POM or PA – in pure or modified form. You can also obtain gears made of PE-UHMW / St 1000® plastic from us in a wide range of colors.
Furthermore, plastic gears offer various properties and advantages that make them more attractive for different applications than metal gears, for example.
Here are some of the most important features:
Lightweight
Plastic gears are significantly lighter than metal gears.
Corrosion resistance
They do not rust and are resistant to chemicals.
Good wear resistance
Certain plastics have a high abrasion resistance.
Self-lubricating properties
Some plastics offer natural lubricity.
Susceptibility to moisture absorption
Some plastics such as nylon PA 6 G can absorb moisture.
Moldability
Plastic enables the production of complex shapes and fine details.
Temperature resistance
Limited resistance to high temperatures above 150 °C.
Electrical insulation
Plastics are non-conductive and offer insulating properties.
Advantages of plastic gears
Plastic gears are becoming increasingly popular in the industry due to their versatile properties and wide range of applications. They offer a number of advantages over traditional metal gears that make them attractive for a wide range of applications. Listed below are some of the key benefits of plastic gears that make them a preferred choice for designers and engineers in various industries.
- Maintenance-free use
- Almost unlimited in design
- High wear resistance
- High resilience (PA and POM)
- Low noise
- Corrosion resistance
- Vibration damping
- Lower weight (therefore lower mass moment of inertia)
Customized gears for every industry
Depending on the intended use and industry, some plastics are more suitable for gears than others. POM, for example, is often used in the automotive industry or in yacht and shipbuilding, while PA 6 G is mainly used in tool and machine manufacturing.
Here are some of the most important industries in which plastic gears are frequently used:
Automotive industry
Plastic gears are used in various vehicle components, such as windshield wiper systems, seat adjusters, window regulators and air conditioning systems, to save weight and reduce noise.
Electrical and electronics industry
Plastic gears are used in household appliances such as washing machines, dishwashers, microwaves and printers because they run quietly and provide electrical insulation.
Medical technology
Plastic gears are used in medical devices such as insulin pumps, prostheses and diagnostic instruments due to their lightweight construction and biocompatibility.
Mechanical engineering
Plastic gears are used in smaller machines and devices that need to operate quietly and with low maintenance, such as packaging machines or conveyor systems.
Toy industry
Plastic gears are often used in toy manufacturing to cut costs and reduce the weight of products.
Office equipment
Devices such as copiers, printers and scanners use plastic gears to work quietly and efficiently.
Domestic appliances and food processors
Plastic gears are used in products such as blenders, coffee machines and food processors as they are corrosion-resistant and easy to clean.
Aerospace
In the aerospace industry, plastic gears are used to save weight and reduce mechanical complexity, especially in non-critical systems.
Consumer goods industry
Plastic gears are widely used in a variety of consumer goods, from electric toothbrushes to gardening tools, due to their cost efficiency and versatility.
Robotics and automation
Plastic gears are used in robotics and automated systems due to their lightweight construction and design flexibility.
