How Korea Ever-Power Designs Custom Plastic Gears<\/h2>\n

\"Ever-Power<\/p>\n

Every custom plastic gear starts with a design process that translates application requirements into a manufacturable gear specification. Korea Ever-Power’s engineers guide customers through each stage:<\/p>\n

\n
\n

Step 1 \u2014 Application Analysis<\/h3>\n

Before designing the gear, Korea Ever-Power engineers define the application requirements: required torque and speed at the gear; duty cycle (continuous vs intermittent); ambient temperature range; chemical and moisture environment; required service life; available space envelope; shaft arrangement (parallel, 90\u00b0, or other); and required precision grade. These inputs determine the gear type, module, face width, material, and tooth form \u2014 errors at this stage propagate into expensive mould rework or short gear life.<\/p>\n<\/p><\/div>\n

\n

Step 2 \u2014 Tooth Flank Design<\/h3>\n

Plastic gear tooth flanks are designed to minimise moulding stress while maximising load-carrying capacity. The tooth root radius is typically increased beyond the standard involute value to reduce the stress concentration at the root \u2014 where injection-moulded plastic gears most commonly fail by fatigue fracture under repeated loading. The tooth tip is designed for adequate clearance with the mating gear under all temperature and moisture conditions \u2014 dimensional change in plastic gears is larger than in metal, so adequate clearance at the cold\/dry extreme prevents interference at the hot\/wet equilibrium condition.<\/p>\n<\/p><\/div>\n

\n

Step 3 \u2014 Module and Face Width Selection<\/h3>\n

Smaller modules (finer teeth) give smoother action and lower noise but reduce load capacity per unit face width. The minimum practical module for injection-moulded plastic gears is M0.1\u2013M0.2 (for POM); below M0.5, tooth form accuracy becomes highly dependent on mould quality and shot-to-shot consistency. Face width is chosen to give adequate tooth contact area at the operating load, but slightly narrower than the equivalent steel gear \u2014 reducing the risk of mechanical interference at the toe end and stress concentration from tooth misalignment due to plastic shaft\/housing deflection under load.<\/p>\n<\/p><\/div>\n

\n

Step 4 \u2014 Mould Steel Selection<\/h3>\n

Korea Ever-Power selects mould steel by the gear’s production volume and precision requirement: S136H (stainless, corrosion-resistant) for food-grade or medical gear moulds where the mould itself must resist cleaning chemicals; NAK80 (pre-hardened, good polishability) for standard high-precision optical-surface gear moulds; 718H (pre-hardened, good toughness) for large moulds where toughness is prioritised; SKD61\/H13 hot-hard for high-volume, long-life moulds at maximum hardness; 420 hot-hard for maximum corrosion resistance at high hardness. The correct mould steel selection determines mould life in millions of shots.<\/p>\n<\/p><\/div>\n

\n

Step 5 \u2014 Diameter Design Rule<\/h3>\n

Korea Ever-Power designs plastic gears with rim diameter greater than 1 \u00d7 module \u00d7 tooth count \u2014 ensuring adequate rim material behind the tooth root to support the tooth root bending moment and distribute the stress through the rim before it reaches the gear bore\/hub. This is especially important for plastic gears where the lower elastic modulus means more deflection at the tooth under load \u2014 if the rim is too thin, the rim deflects under tooth load, changing the contact geometry and accelerating wear at the heel or toe end of the tooth.<\/p>\n<\/p><\/div>\n

\n

Prototype Before Production<\/h3>\n

For new custom gear designs, Korea Ever-Power strongly recommends CNC-machined prototypes before mould commitment. A machined prototype in the specified material (POM, nylon, PEEK) tests the tooth form, fit, and function in the application before the significant tooling investment. If the prototype test identifies a required change (module, tooth count, bore diameter, face width), the change is made to the drawing and the corrected prototype is tested again \u2014 all at minimal cost compared with modifying a finished mould. Only after prototype approval does the mould tooling manufacturing begin.<\/p>\n<\/p><\/div>\n<\/div>\n

<\/p>\n

Where Custom Plastic Gears Are Used<\/h2>\n

\"measuring<\/p>\n

\n
\n
<\/div>\n

Automotive \u2014 Fastest Growing Segment<\/h3>\n

Automakers integrate plastic gears into liftgates, power seats, electronic throttle bodies, turbo actuators, mirror adjusters, window lift drives, and HVAC blend door actuators. PA66+GF30 gears dominate automotive applications for their high strength and temperature resistance; POM gears suit lower-temperature interior applications. Korea Ever-Power holds TS16949 certification and manages the full mould-to-production supply chain for automotive OEM gear requirements.<\/p>\n<\/div>\n

\n
<\/div>\n

Medical Equipment<\/h3>\n

PEEK and POM custom plastic gears in surgical robots, infusion pumps, diagnostic analysers, and rehabilitation equipment. Biocompatibility requirements (FDA-listed POM; PEEK for implant-adjacent contact), cleanroom manufacturing, full material traceability, and ISO9001 certification align with Korea Ever-Power’s standard quality systems for medical device gear supply.<\/p>\n<\/div>\n

\n
<\/div>\n

Semiconductor Equipment<\/h3>\n

PEEK and PPS custom plastic gears in semiconductor wafer handling robots, chemical vapour deposition chamber drives, and photolithography positioning mechanisms. Semiconductor equipment demands zero metallic particle contamination (metal gear wear is disqualifying), chemical resistance to aggressive process gases and cleaning chemicals (PEEK and PPS only), and ultra-high dimensional repeatability (DIN5\u20136 precision) for nanometre-level wafer positioning.<\/p>\n<\/div>\n

\n
\ufe0f<\/div>\n

Food and Packaging Machinery<\/h3>\n

POM, UHMWPE, and food-grade PA custom gears in food processing, filling, and packaging machinery. FDA-listed materials, no-lubrication operation, corrosion resistance against acidic and alkaline cleaning agents (CIP), and easy visual inspection for wear damage (distinctive colour \u2014 natural POM is white, worn gear shows bare surface differently from new) are all characteristics of Korea Ever-Power food-grade gear designs.<\/p>\n<\/div>\n

\n
<\/div>\n

Robotics and Automation<\/h3>\n

POM and nylon custom plastic gears in collaborative robots, educational robots, automated guided vehicles, and industrial positioning systems. The combination of low weight (for robot arm inertia minimisation), self-lubrication (sealed joint drives), corrosion resistance (outdoor AGV operation), and competitive cost at production volumes makes custom plastic gears the standard choice for the gear train stages in collaborative robot joints rated up to 50 Nm.<\/p>\n<\/div>\n

\n
<\/div>\n

Toys and Consumer Products<\/h3>\n

ABS and nylon custom gears in RC vehicles, educational toys, smart home devices, and consumer appliances. The combination of low per-part cost (injection moulding economics), design freedom (complex hub features, snap-fits, and integrated features in one part), and safety compliance (no heavy metals, no sharp edges) at consumer price points makes Korea Ever-Power custom plastic gear moulding the standard approach for consumer product gear drives at annual volumes above ~10,000 units.<\/p>\n<\/div>\n<\/div>\n

<\/p>\n

Frequently Asked Questions<\/h2>\n
\n
\n

What is the first thing to consider when choosing a plastic gear material?<\/p>\n

Strength \u2014 the material must be rigid enough to withstand the expected loads without exceeding its allowable tooth root bending stress. After strength, consider: temperature resistance (must exceed the maximum operating temperature with adequate margin); water absorption (low absorption materials like POM or PPS for humid environments); friction coefficient (self-lubricating grades for maintenance-free drives); and chemical resistance (PPS, PEEK, or PTFE for aggressive chemical environments). Korea Ever-Power engineers will confirm the best material choice after reviewing your application requirements, load data, and operating environment.<\/p>\n<\/div>\n

\n
\n

What is the minimum order quantity and lead time for custom plastic gears?<\/p>\n

There is no enforced minimum order quantity \u2014 Korea Ever-Power accepts development samples (1\u201310 pcs from CNC machining, 5\u201350 pcs first mould shot) through to high-volume production orders. Mould tooling lead time: 25\u201335 days for standard complexity; 15 days for simple small moulds. Series production lead time after mould approval: 10\u201320 days depending on quantity and current factory loading. Contact Korea Ever-Power with your specification and required delivery schedule for a specific commitment.<\/p>\n<\/div>\n

\n
\n

Can prototype gears be tested before committing to mould tooling?<\/p>\n

Yes \u2014 Korea Ever-Power CNC-machines prototype gears in the specified plastic material (POM, nylon, PEEK, etc.) before mould design begins. Machined prototypes allow functional testing \u2014 including torque, noise, fit, and life testing \u2014 before the mould investment is committed. This prototype-first approach is strongly recommended for new gear designs: changes to module, tooth count, or bore at the prototype stage cost far less than the equivalent mould modification after tooling is cut. Contact Korea Ever-Power<\/a> with your gear drawing or application description to begin.<\/p>\n<\/div>\n<\/div>\n
