Product Overview<\/h2>\n
\n
\n \"Plastic\n <\/div>\n
\n

POM black star wheel plastic components<\/strong> for conveyors and machinery are precision plastic parts machined or injection-moulded from POM (Polyformaldehyde \/ Delrin \/ Acetal) \u2014 the engineering thermoplastic known as “plastic steel” for its outstanding wear resistance, high hardness, dimensional stability, and low friction coefficient. POM black star wheels are used wherever a plastic gear, timing wheel, cam wheel, or star-profile conveyor component must operate reliably in continuous-duty conveyor, machinery, or transmission service. Korea Ever-Power supplies these components from its Hangzhou factory. Place of origin: Hangzhou, China. Model: POM wheel. Plastic modelling type: per drawing. Colour: natural, white, black, rice yellow, and others. Water absorption (23\u00b0C in air): 0.17\u20130.20% \u2014 near-zero hygroscopic growth for dimensional stability in wet environments.<\/p>\n

Korea Ever-Power’s POM black star wheels<\/a> are increasingly replacing metal gears in conveyors and machinery because new developments in POM materials and CNC machining allow engineers to produce plastic gear components that are more durable, quieter, and more cost-effective than the metal components they replace. Plastic star wheels are less expensive to produce, reduce noise significantly, limit vibration and shock, and are corrosion-free.

Selecting the Right Plastic Star Wheel for Your Conveyor or Machine<\/h2>\n

\"White<\/p>\n

Plastic star wheels can come in all shapes and sizes for a variety of purposes. Choosing correctly for your conveyor or machinery application requires understanding the key selection factors:<\/p>\n

\n
\n

Material \u2014 POM vs MC Nylon vs UHMW-PE<\/h3>\n

POM black star wheels: best for precision transmission (highest stiffness, lowest water absorption, best dimensional accuracy); suitable for conveyor timing wheels, cam wheels, and gear wheels where tooth profile accuracy is critical. MC Nylon: best for high-load conveyor drives (higher bending strength than POM, better shock absorption, available in large diameters). UHMW-PE: best for chain sprocket wheels (best wear resistance, lowest friction, best chemical resistance for food processing and chemical plants). Korea Ever-Power helps customers select the correct material for each specific conveyor or machinery application.<\/p>\n<\/p><\/div>\n

\n

Colour \u2014 Functional and Aesthetic Choices<\/h3>\n

Black POM star wheels are the most common colour for conveyor and machinery components \u2014 black carbon-black masterbatch addition provides UV stability for outdoor-exposed components and improves fatigue resistance in cyclic stress applications. Natural white or rice yellow POM suits food-grade applications where colour-coding of plastic components is used for cleaning verification (contamination is visible on light-coloured surfaces). Custom colours available for brand-specific colour coding or component identification in complex multi-material assemblies.<\/p>\n<\/p><\/div>\n

\n

Size Range \u2014 Small Gearboxes to Heavy-Duty<\/h3>\n

POM star wheels from Korea Ever-Power are available across a wide size range. Some are designed for small gearboxes (\u00d810\u201350 mm, injection-moulded); others are for heavy-duty use (\u00d8100\u2013500 mm, CNC-machined from POM or MC Nylon plate\/rod). The star wheel size is determined by the conveyor’s chain pitch (for sprocket-type star wheels), the product container diameter (for bottle-sorting star wheels), or the machine’s gear pitch circle diameter (for transmission star wheels). Korea Ever-Power engineers the correct star wheel size from your product dimensions or chain specification.<\/p>\n<\/p><\/div>\n

\n

Low Coefficient of Friction \u2014 Heavy-Duty Use<\/h3>\n

Plastic star wheels for heavy-duty applications should be designed with a low coefficient of friction to minimise heat generation and tooth wear at sustained high loads. POM’s \u03bc \u2248 0.10 against steel is adequate for most conveyor and machinery applications; for the most demanding continuous-duty drives, oil-containing MC Nylon (\u03bc \u2248 0.06\u20130.08) or UHMW-PE (\u03bc \u2248 0.04\u20130.08) provide further friction reduction. Korea Ever-Power confirms the correct material grade for your load and duty cycle before production.<\/p>\n<\/p><\/div>\n

\n

Noise and Vibration Reduction<\/h3>\n

Plastic star wheels are quieter than metal gears and far less likely to produce harsh sounds that can harm workers’ hearing. Constant noise can distract workers and cause long-term hearing damage \u2014 OSHA and EU workplace noise regulations require engineering controls when noise exceeds 80\u201385 dB(A). Replacing metal star wheels and timing wheels with POM plastic equivalents typically reduces gear-source noise by 6\u201312 dB(A), often bringing the machinery below regulatory action levels without enclosures. Plastic star wheels are also more effective at limiting vibration and shock than metal \u2014 POM’s damping coefficient absorbs transmission impulses that metal would radiate as both noise and structural vibration.<\/p>\n<\/p><\/div>\n

\n

Increasing Replacement of Metal Gears<\/h3>\n

Plastic star wheels are increasingly replacing metal gears in conveyors and machinery across industries. New developments in POM and engineering plastic compounds, combined with precision CNC machining capability, allow engineers to produce plastic star wheel components with durability, dimensional accuracy, and load capacity that match or exceed the metal components they replace \u2014 at lower cost, with less noise and vibration, and without the corrosion and lubrication maintenance requirements of metal gears. Korea Ever-Power has supplied plastic star wheel replacements for metal components in bottling, packaging, food processing, and agricultural machinery clients globally.<\/p>\n<\/p><\/div>\n<\/div>\n

Applications<\/h2>\n

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

\n
\n
<\/div>\n

Beverage Bottling and Filling Lines<\/h3>\n

POM black star wheels in bottle-spacing, orientation, and transfer star wheel stations on beverage filling lines \u2014 operating at speeds up to 60,000 bottles\/hour. The black colour provides UV stability in outdoor-exposed filling facilities; the 0.17\u20130.20% water absorption maintains dimensional accuracy through high-pressure washdown cycles; and the non-contaminating, chemical-resistant POM surface meets food-contact material compliance requirements.<\/p>\n<\/div>\n

\n
<\/div>\n

Packaging and Sorting Conveyors<\/h3>\n

POM star wheels in parcel sorting conveyor deflector drives, tilt-tray sorter timing mechanisms, and packaging line accumulation conveyor drives. Conveyor systems require star wheel components with consistent tooth profiles (for product spacing accuracy), noise below workplace regulations (POM is 6\u201312 dB quieter than steel), and long service life without maintenance (POM self-lubricating, no re-greasing required in sealed conveyor drive housings).<\/p>\n<\/div>\n

\n
<\/div>\n

Industrial Machinery Drives<\/h3>\n

POM star wheels replacing metal gears in industrial textile machinery drives, printing machine timing mechanisms, and rubber processing equipment drive trains. In textile and printing environments, the no-lubricant operation of POM star wheels eliminates the oil contamination of product that metal gears with grease lubrication risk. The noise reduction from plastic star wheels improves the working environment of operators in close proximity to the machinery throughout their shift.<\/p>\n<\/div>\n

\n
<\/div>\n

Automotive Assembly Conveyors<\/h3>\n

POM star wheels in automotive assembly line conveyor drive heads, part handling transfer mechanisms, and paint shop conveyor drives (chemical resistance to paint solvents and cleaning agents is required). Automotive assembly conveyors run continuously 24 hours\/day in production and the noise level must comply with factory acoustic standards \u2014 POM star wheels contribute to both requirements simultaneously.<\/p>\n<\/div>\n

\n
<\/div>\n

Agricultural and Outdoor Machinery<\/h3>\n

POM black star wheels in combine harvester cleaning shoe drives, grain auger mechanisms, and outdoor irrigation system pump drives. Black POM’s UV-stabilised carbon black addition resists outdoor UV degradation significantly better than natural (off-white) POM or nylon \u2014 extending service life in the direct sunlight exposure of agricultural outdoor machinery by 3\u20135 years compared with unstabilised alternatives.<\/p>\n<\/div>\n

\n
<\/div>\n

Pharmaceutical and Medical Conveyors<\/h3>\n

Natural white or rice yellow POM star wheels in pharmaceutical tablet counting and filling lines, blister packaging machines, and medical device assembly conveyors. Light-coloured POM star wheels support contamination detection \u2014 any black particle (from gear wear) is immediately visible on the white POM surface, enabling prompt detection and removal of any particulate contamination before it reaches the product. Korea Ever-Power’s FDA-listed POM material also satisfies pharmaceutical material compliance documentation requirements.<\/p>\n<\/div>\n<\/div>\n

Customer Reviews<\/h2>\n
\n
\n

“We operate beverage filling lines and replaced all metal timing star wheels with POM black star wheels (12-point, OD 240 mm) from Korea Ever-Power. Previous metal star wheels required lubrication every 200 hours and produced 71 dB(A) at 0.5 m. POM replacements: zero lubrication for 14 months confirmed; noise: 61 dB(A) \u2014 10 dB reduction. Dimensional check at 14 months: star point radius within 0.04 mm of original specification. Korea Ever-Power’s pre-shipment video inspection confirmed all dimensions before despatch \u2014 saved us an incoming inspection visit to China.”<\/p>\n
