Factory Customized Nylon Gear Rack — Overview
Ever-Power factory customized nylon gear racks are produced by hobbing from nylon and PA engineering polymer bar stock to any customer-specified module, cross-section, length, and hole pattern. The hobbing process — in which a rack-tooth cutter engages the polymer blank on a gear hobbing machine — delivers consistent tooth geometry, correct pressure angle, and accurate pitch spacing across the full length of the rack, batch after batch. This makes factory-hobbed nylon racks the preferred production method for OEM customers who require consistent dimensional quality for series production of automation equipment, gate systems, and agricultural machinery.
The factory supplies blue, natural, white, and black coloured nylon racks as standard colour options, reflecting the different nylon and PA grades most commonly used in rack applications: natural (off-white) for standard PA6 and PA66 mechanical grades, blue for MC901 oil-impregnated cast nylon, white for food-safe PA grades, and black for UV-stabilised outdoor grades. All colours are available in any module and length per customer drawing. Worm gear sets, bevel gears, ring gears, and helical gears are also available from the same factory for complete gear train procurement.

Factory Hobbing Process — Why It Matters for Nylon Racks
⚙ Consistent Tooth Geometry
The hobbing process uses a rotating hob cutter that generates the involute tooth form by simultaneous cutter rotation and blank feed — the same process used for precision steel racks. This generates a tooth profile that is geometrically consistent along the full rack length, unlike hand-milled or injection-moulded racks where tooth-to-tooth pitch error can vary significantly across the part.
📈 Scalable from Sample to Production
Factory hobbing is equally economical for prototype quantities of one or a few pieces and for production runs of hundreds or thousands of identical racks. The CNC hobbing program for a specific module and cross-section combination is retained and recalled for repeat orders — ensuring dimensional consistency between the prototype and every subsequent production batch.
🌿 Colour Selection for Application
Blue (MC901): standard for oil-impregnated cast nylon — highest wear resistance and impact toughness for commercial gate and high-cycle automation drives. Natural: standard PA6 or PA66 for general industrial and residential gate applications. White: food-safe PA66 for food-contact conveyor and packaging equipment. Black: UV-stabilised PA66 for outdoor applications exposed to direct sunlight.
⛜ Matched Pinion Sets
Factory-hobbed nylon racks can be supplied as matched sets with a compatible steel or nylon pinion. Rack and pinion are meshed and roll-tested together before shipment to verify backlash, contact pattern, and noise level as a pair. This eliminates field-fitting uncertainty and ensures the drive performs as specified from the first installation.

Material of Plastic Gear Rack
Plastic racks can be made from a variety of materials. The traditional PR series uses MC nylon, while the PRF series adds end machining to connect multiple sections for long-travel drives. The polyacetal-based DRFD and DRFK series include mounting holes. The injection-moulded DR series has unique flexibility properties suitable for curved-path locations. The material selected depends on the daily cycle count, the required force, and the environment — moisture, chemical exposure, and temperature. Dimensional stability is critical for maintaining gear tooth contact ratio, tooth tip clearance, and overall geometry throughout the service life.
Quality Assurance and Manufacturing

Ever-Power factory-customized nylon gear racks are produced under ISO 9001:2015 quality management by hobbing on precision CNC gear hobbing machines. Incoming nylon bar stock is verified for grade and density before entering production. Tooth geometry, pitch accuracy, cross-section dimensions, and rack straightness are inspected on every batch. Every order ships with material datasheet and dimensional inspection report.
ISO 9001:2015 and Quality Certificates
Documentation with every order:
- ISO 9001:2015 dimensional inspection — tooth pitch, profile, cross-section, straightness
- Material datasheet — nylon/PA grade, density, tensile strength, colour grade
- Roll-test report for matched rack and pinion set orders
- Production video documentation available on request before shipment

Domande frequenti
What is hobbing and why is it the preferred production method for nylon gear racks?
Hobbing is a continuous gear-cutting process in which a helical hob cutter rotates in synchronisation with the workpiece to generate the involute tooth profile. For nylon rack production, hobbing delivers consistent tooth pitch and profile accuracy across the full rack length — an important quality characteristic for drives where uneven pitch would cause periodic velocity variation (transmission error) manifesting as noise or positioning error. Hobbing also allows very high production rates for long production runs of a fixed module and cross-section, making it more economical than single-point milling for standard rack dimensions.
What is the standard lead time for a factory-customized nylon rack order?
The standard lead time for a custom hobbed nylon rack is 7-14 working days from drawing approval for CNC-hobbed bar stock racks. For first injection mould orders the mould tooling lead time is 15-35 days; re-orders from existing mould tooling are typically 5-7 days. Rush services are available for urgent requirements — contact us with your required delivery date and we will advise the feasibility and any premium lead time cost.
Can I order a single prototype rack before committing to a production quantity?
Yes. Single prototype pieces are accepted for all custom nylon rack specifications with no minimum order quantity. The prototype is produced to the same drawing specification and quality standard as the production order — it is not a hand-made sample but a production-representative piece machined on the same CNC hobbing equipment. The prototype piece ships with the same dimensional inspection report as a production order, allowing you to verify the specification before committing to a larger quantity.
