Plastic Spur Gears

High quality Plastic spur gears from a China manufacturer,Feida Machinery.They are cylindrical gears with teeth parallel to gears axis, used to transfer motion and power between parallel shafts.

Basic parameters

Module:Is the basic parameter determining gear size.The larger the moulde,the larger and stronger the teeth.
Number of teeth:Affects gear ratio and size.
Pressure angle:Affects root strength and is typically 20 dregee.
Pitch circle:is the reference circle used to calculate gear dimensions.
Addendum circle and dedendum circle:The gear’s outer circle and the circle at the bottom of the tooth spaces.

Main plastic materials

The common materials include nylon,POM,PEEK,etc.,which suit different working conditions.
Nylon features high impact resistance,excellent self-lubrication,and low cost.
POM features high rigidity,ultra-low friction coefficient(0.1-0.3),exceptional demensional stability ,and shot molding cycles.
Peek features extreme heat and chemical resistance,ultra-high stength/wear resistance ,and minimal creep.

Manufacturing Process and Main Equipment

With more than 30 years of experience,Feida has stable manufacturing processes, which include injection molding or precision machining.

In addition,We continuously introduces advanced production equipment and technical capabilities to meet the growing market demand and higher product quality requirements.The cnc machining equipment includes cnc lathe,cnc gear hobber, cnc gear shaper,cnc gear shaving machines, cnc gear grinder,cnc machining center,etc. The inspection instruments include mechanical test machine, material analysis spectrometer, coordinate measuring machines (CMM), roughness tester,hardness tester,etc.Thus,We are confident in supplying high precision straight spur gears made of nylon,pom and peek to our clients.

How do you control the quality?

Feida has the ISO9001:2015 quality control system certificate and a strong QC team during production. We strictly control quality through these systems, which involve at least 3 quality inspections: incoming material inspection, in-process inspections (including first-piece, self-inspection, and patrol inspection), and final product inspection before shipment.

Applications

Automotive Industry

Depending on leverage lightweight construction, weather resistance (operating range from -40°C to 120°C), and quiet operation,Our plastic spur gears are commonly found in windshield wipers, window regulators, power mirror adjusters, and headlight leveling mechanisms.

Home Appliances

Extensively used in washing machines, vacuum cleaners (for reduction gearing), automatic coffee machines, blenders, mixers, and air conditioning systems to reduce vibration and noise.

Office Automation & Electronic Devices

Widely applied in printers, copiers (paper-feed drives), paper shredders, fax machines, and DVD player mechanisms, cameras, where precision, low noise, and lightweight design are critical.

Medical Devices

Used in dental chairs, infusion pumps, and similar equipment, meeting requirements for low friction, sterility, and resistance to disinfectants.

Food & Packaging Machinery

Found in food mixers, filling machines, etc. Using FDA-approved nylon materials prevents metal contamination and eliminates the need for external lubrication.

Toys & Light Industry

The first choice for precision drive components in toys, clocks, and watches due to low cost and light weight.

Special Environments & Industrial Equipment

Employed in underwater robots (resistant to seawater corrosion), chemical valves (acid/alkali resistant), machine tools, etc., leveraging their corrosion resistance and self-lubricating properties to handle challenging conditions.

Certification & Packaging

With a good reputation, strong technical strength, reliable product quality, high-quality service attitude, Feida wons the trust of many customers at home & abroad.

To prevent finished products from rusting and being damaged during transportation, we will design appropriate packaging according to the product's shape, size, and intended use, such as plastic boxes, outer mesh bags, rust-resistant paper, bubble bags, cartons,and wooden boxes.

FAQ

What are the advantages of plastic spur gears compared to metal spur gears?

The advantages include light weight,lower noise & vibration,self-lubrication,corrosion resistance,lower cost,etc.

What is injection molding?

Injection molding is a highly efficient manufacturing process for producing plastic parts in large volumes. In simple terms, it involves injecting molten plastic under high pressure into a precision-made mold, then cooling it and opening the mold to eject the finished part.

How do you handle for small batch/prototyping?

For small batch/prototyping,we typically use a gear hobbing machine or CNC milling machine to cut the gear from a plastic rod.
