What Is a Non-Standard Plastic Gear?

A non-standard plastic gear is any gear whose parameters — module, tooth count, bore diameter, face width, helix angle, pressure angle, or external profile — fall outside the standard catalogue ranges of plastic gear distributors. Most catalogue plastic gear suppliers stock modules M0.5, M1.0, M1.5, M2.0, and M2.5 in limited tooth-count ranges. Any gear requiring a non-standard module (e.g. M0.7, M1.25, M3.0, M4.0, or metric/DP conversions), an unusual tooth count, or a custom bore/keyway is non-standard and must be produced by Korea Ever-Power's custom injection moulding or CNC machining service.

Module Range 0.5–5.0 and Beyond

Korea Ever-Power's standard module range for non-standard MC Nylon injection gears is M0.5–M5.0 — covering the vast majority of plastic gear applications from micro precision drives (M0.5 gears in instrument and electronics mechanisms) to medium industrial drives (M5 gears in conveyor and agricultural machinery). For modules outside M0.5–M5.0, Korea Ever-Power can still provide non-standard injection moulding (M0.3–M0.4 for micro gears; M6–M10 for larger industrial plastic gears by CNC machining from cast MC Nylon) — the feasibility is confirmed at inquiry stage based on minimum tooth size and mould tool complexity.

Oil-Containing MC Nylon Gear — Built-In Lubrication

The oil-containing (oil-grade) MC Nylon gear incorporates lubricant oil uniformly distributed within the MC Nylon matrix during the casting process. As gear tooth surfaces wear microscopically under contact loading, the dispersed lubricant migrates to the contact zone, providing continuously replenished boundary lubrication. This built-in oil-grade lubrication distinguishes oil-containing MC Nylon from dry MC Nylon: lower friction coefficient (μ ≈ 0.06 vs 0.15 for dry MC Nylon), lower operating temperature (less frictional heat), quieter mesh noise (reduced contact impulse from lubricated engagement), and longer tooth surface life. Green or blue colour is the standard visual identifier for oil-containing MC Nylon parts.

Injection Rack Pinion Gear — Non-Standard Plastic R&P

The injection rack pinion gear designation covers both the rack (linear gear) and the pinion (driving circular gear) produced by Korea Ever-Power's non-standard injection moulding service. Non-standard injection plastic rack and pinion sets serve applications where the required module, rack length, or pinion tooth count falls outside catalogue offerings — CNC machine axis drives with custom pitch-per-rev, conveyor line drives with specific pitch and face width, and precision positioning systems with required backlash below catalogue tolerance. Korea Ever-Power produces matched non-standard plastic rack and pinion sets with consistent module and pressure angle from a single mould order.

Free Sample — Risk-Free Evaluation

Korea Ever-Power's free sample policy for non-standard MC Nylon injection gears: after the customer approves the gear drawing and pays the mould tool cost, Korea Ever-Power provides free injection moulded samples (typically 5–20 pieces) for dimensional and functional evaluation in the customer's application. The customer pays only freight for sample delivery. Free samples allow full evaluation of the non-standard gear's dimensional accuracy, material properties, and fit in the mechanism before the production order is confirmed — eliminating the risk of investing in production volumes before the design is validated.

Injection Mould Steel Selection — Quality and Life

Korea Ever-Power's injection mould steel selection for non-standard MC Nylon gear moulds: S136H (mirror-polish, corrosion-resistant — for food-grade POM or transparent PC gears); NAK80 (high polishability — for cosmetically important visible gear surfaces); 718H (high toughness, long mould life — for PA66+GF30 high-volume automotive gears); SKD61 / H13 (hot-hard — for PPS and PEEK gears requiring high mould temperature 150–200°C); 420 hot-hard (extreme wear resistance — for glass-filled or mineral-filled gear compounds). Correct mould steel selection ensures the tooth surface finish and cavity dimensional accuracy are maintained across the full production life of the mould.

Non-Standard Module Drives

Oil-containing MC Nylon injection gears in non-standard modules (M0.6, M0.75, M1.25, M3.0, M4.0) for equipment that was designed with a specific pitch-per-revolution requirement not achievable with standard modules. Korea Ever-Power designs the non-standard mould cavity for the required module, ensures the correct involute tooth profile generation, and produces the non-standard MC Nylon injection gears to the same ISO9001 quality standard as all production.

Custom Rack and Pinion Mechanisms

Non-standard injection MC Nylon rack and pinion sets for custom automation and robotics systems where the linear travel per pinion rotation, rack length, or rack cross-section is not available in standard catalogue form. Oil-containing MC Nylon rack and pinion sets for sealed linear drives where no external lubricant can be applied — the oil-grade self-lubrication maintains low friction for the mechanism's service life without maintenance access.

Packaging and Conveyor Custom Drives

Non-standard injection nylon gears for packaging machine timing drives and conveyor indexing mechanisms where the product pitch requires a specific gear ratio achievable only with a non-standard tooth count or module. Korea Ever-Power's non-standard injection service provides exactly the tooth count and module combination required by the packaging machine's kinematic design, without forcing the equipment designer to round to the nearest standard gear size and compromise the machine's performance.

Laboratory and Scientific Instruments

Non-standard oil-containing MC Nylon injection gears (M0.5–M1.0 fine pitch) for laboratory instrument sample drives, spectrophotometer positioning gears, and scientific instrument gear trains where the standard catalogue tooth count does not provide the required transmission ratio. Korea Ever-Power produces non-standard fine-pitch injection MC Nylon gears with tooth profiles meeting the geometric requirements of scientific instrument precision drive applications.

Medical Device Non-Standard Gears

Non-standard injection POM-C and PEEK gear accessories for medical device mechanisms — infusion pump peristaltic drive gears in non-standard module, surgical instrument drives with custom tooth profiles, and diagnostic device positioning gears. Korea Ever-Power's FDA material certificates, ISO9001 quality records, and batch traceability documentation support medical device OEM supplier qualification for non-standard injection plastic gear components.

OEM Spare Parts and Replacement Gears

Non-standard injection MC Nylon gears as OEM spare parts for equipment manufacturers who originally specified non-standard plastic gears in their products — and need a reliable Hangzhou supplier to re-produce the original non-standard specification when OEM tooling is transferred or the original moulds need replacement. Korea Ever-Power's non-standard injection moulding service becomes the ongoing spare parts supplier for the OEM's non-standard plastic gear, maintaining the original specification across production batches for the equipment's full spare parts supply life.

What is the minimum quantity for non-standard injection MC Nylon gears from Korea Ever-Power?

Korea Ever-Power accepts sample orders (minimum 1 piece from stock for standard sizes; free sample from first mould shot after mould tooling payment for non-standard) with no minimum quantity commitment. For non-standard injection moulds, the minimum practical production quantity is 50–200 pcs per order (depending on part size and mould cycle time) to make injection moulding economical vs CNC machining. For quantities below 50 pcs, Korea Ever-Power recommends CNC machining the same MC Nylon specification without mould tooling investment. Korea Ever-Power quotes both options (injection mould vs CNC) and recommends the most cost-effective method for the customer's required annual volume.

What is the difference between wear-resistant and oil-containing MC Nylon gears?

Wear-resistant MC Nylon: standard dry-grade cast MC Nylon with high molecular weight, providing 2–4× better abrasion resistance than injected PA6/PA66 — the "wear-resistant" designation distinguishes it from lower-grade nylon. Used in dry-running gear applications where the MC Nylon's inherent self-lubrication and abrasion resistance are sufficient. Oil-containing MC Nylon (oil-grade): cast MC Nylon with lubricant oil incorporated during casting — provides significantly lower friction (μ ≈ 0.06 vs 0.15), lower noise, and longer tooth surface life than dry MC Nylon. Used where continuous-duty sealed gear drives require the maximum self-lubrication from the plastic material without external lubricant. Green or blue colour indicates oil-containing grade. Korea Ever-Power recommends oil-containing MC Nylon for all sealed continuous-duty drives. Contact Korea Ever-Power to discuss which grade is correct for your application.

"We manufacture automated analytical instruments and needed a non-standard POM injection rack pinion gear set (M0.75, 15T pinion + 18-tooth rack section) — a completely non-catalogue specification. Korea Ever-Power designed the non-standard mould, produced drawing for our approval in 5 days, and delivered free samples in 24 days. Rack-to-pinion pitch step measured on CMM: 0.003 mm maximum error across the rack — within our ±0.005 mm specification. Instrument repeatability with the non-standard Korean rack and pinion: ±0.008 mm over 500 positioning cycles. Korea Ever-Power is now our sole supplier for all non-standard plastic drive components."

"We produce EV charging cable management reels and needed non-standard oil-containing green MC Nylon spur gears (M3, 22T, custom keyway) for our motorised reel gear stage — no catalogue supplier had this exact combination. Korea Ever-Power injection moulded from oil-containing MC Nylon with H13 mould steel. Free samples confirmed: oil-grade confirmed by colour (bright green), friction confirmed by test (μ measured 0.063 at 0.5 m/s). After 30,000 reel extension/retraction cycles: no measurable tooth wear, no external lubricant added. Sealed drive housing shows zero lubricant residue on inspection — confirms oil-grade self-lubrication is contained within the gear, not migrating to the reel mechanism."
