PTFE-filled POM (2% PTFE) reduces the POM gear-to-steel friction coefficient from 0.28 to 0.12 \u2014 enabling dry-run life of 5,000+ hours in light-load packaging auxiliary drives at &lt; 500 RPM<\/p>\n<\/div>\n<\/div>\n<section style=\"margin: 64px 0 0;\">\n<h2 style=\"font-size: clamp(18px,2.6vw,24px); font-weight: 800; color: #1c2330; margin: 0 0 20px; padding-bottom: 10px; border-bottom: 3px solid #2563a8;\">Plastic Gear Material Selection for Packaging Machine Subsystems<\/h2>\n<p style=\"font-size: 15.5px; margin: 0 0 20px;\">The packaging machine is unique among industrial machines in the diversity of environments that different gear drives within the same machine experience \u2014 and this internal diversity means a single plastic gear material specification is almost never appropriate for the full machine. A labelling machine illustrates the point: the container rotation drive (rotating each product container so the label wraps 360\u00b0) operates at ambient temperature with the container surface facing the gear, where label adhesive spray or adhesive mist can reach the gear \u2014 POM with PTFE additive (adhesive does not stick to PTFE-coated surfaces) is optimal. The label roll take-up motor drive (winding the waste carrier matrix from the label roll onto a take-up spool) operates in the enclosure beside the print head, at elevated temperature (40\u201360\u00b0C from the print head thermal radiation) \u2014 POM approaches its upper continuous temperature limit at 60\u00b0C; PA66 is preferred for this drive. The print head registration gear (the micro-adjustment mechanism that fine-positions the print head to the label registration mark) operates at high cycle rate with near-zero load \u2014 self-lubricating PTFE-filled POM is ideal. And the main conveyor drive gear (transmitting the motor torque to the main conveyor belt that moves containers through the machine) operates at the highest torque \u2014 PA66 GF30 provides the stiffness needed for repeatable conveyor positioning under varying load.<\/p>\n<p style=\"font-size: 15.5px; margin: 0 0 20px;\">Korea Ever-Power&#8217;s <a style=\"color: #2563a8; font-weight: bold; text-decoration: none; border-bottom: 2px solid #f97316;\" href=\"https:\/\/gearrack.top\/fr\/product-category\/plastic-gear\/\">plastic gears for packaging machines<\/a> are manufactured across the full range of materials used in packaging machine drives \u2014 POM-H and POM-C (standard and PTFE-filled) for labeller and wrapper drives, PA66 GF30 (30% glass fibre reinforced) for higher-load cartoner and case packer drives, and PEEK (polyether ether ketone, natural grade and 30% carbon fibre reinforced) for hot-melt glue system gears and pharmaceutical packaging clean room applications. Korea Ever-Power&#8217;s packaging machine plastic gear design service includes material selection consultation for each drive position in the machine \u2014 the design engineer provides the drive function, operating speed, peak torque, temperature, and any chemical exposure (label adhesive, CIP agents, solvent inks), and Korea Ever-Power recommends the optimal material and minimum module for the design life required.<\/p>\n<p style=\"font-size: 15.5px; margin: 0 0 24px;\">The noise reduction benefit of plastic gears in packaging machinery is one of the most practical advantages of the material \u2014 a label applicator running at 400 containers per minute generates a gear mesh frequency in the range of 800\u20131,500 Hz (depending on the tooth count), directly in the human ear&#8217;s most sensitive frequency range. A steel gear mesh at DIN 7 quality generating 6 \u03bcrad transmission error at this frequency produces a A-weighted sound pressure level of approximately 72\u201375 dB(A) at 1 metre \u2014 above the EU Machinery Directive maximum permissible noise level of 70 dB(A) for operators without hearing protection. A POM gear mesh at the same drive geometry generates approximately 62\u201364 dB(A) at 1 metre \u2014 8\u201312 dB(A) below the steel equivalent \u2014 because the POM&#8217;s lower elastic modulus (2.8 GPa vs 210 GPa for steel) provides structural damping of the tooth impact vibration, and the slightly higher backlash in the plastic gear mesh (typical backlash 0.05\u20130.10 mm vs 0.02\u20130.04 mm for precision steel) reduces the re-engagement impact at each tooth cycle. This noise reduction from plastic gears allows packaging machine builders to meet the EU Machinery Directive noise requirements without adding acoustic enclosures to the drive mechanism, reducing machine cost and improving operator access for job changes and maintenance.<\/p>\n<figure style=\"margin: 0 0 28px;\"><img decoding=\"async\" style=\"width: 100%; height: auto; display: block; border-radius: 6px; border: 1px solid #d1d9e6;\" title=\"Plastic Gear for Packaging Machine \u2014 Korea Ever-Power\" src=\"https:\/\/gearrack.top\/wp-content\/uploads\/2026\/07\/Good-Glide-Characters-EPA-Customized-Nylon-Spur-Gear-Plastic-Gear-Manufacturer.webp\" alt=\"nylon plastic gear packaging machine labeller wrapper Korea Ever-Power\" \/><figcaption style=\"font-size: 12.5px; color: #64748b; margin-top: 10px; padding: 8px 14px; border-left: 4px solid #f97316; background: #fff; line-height: 1.65;\">Korea Ever-Power PA66 GF30 (30% glass fibre reinforced nylon 66) gear set for packaging machine cartoner blank erector drive \u2014 M3, 36T, OD 114 mm, bore 22 mm H7, face width 28 mm. PA66 GF30 flexural strength 210 MPa (vs 80 MPa unfilled PA66 and 90 MPa POM-H) \u2014 the GF30 reinforcement is needed for the cartoner blank erector drive because the peak torque at blank erection (the moment the erected carton blank is squared up and held against the mandrel by the erector mechanism) can reach 8\u201312 Nm, above the continuous design limit of unfilled PA66 at M3. The glass fibre reinforcement also increases the gear\u2019s flexural modulus from 2.8 GPa (unfilled PA66) to 9.5 GPa \u2014 closer to the modulus of steel than any other unreinforced polymer, which is important for positional accuracy of the carton blank erector that must position the blank to \u00b10.5 mm for the glue application and folding operations. Korea Ever-Power PA66 GF30 packaging machine gears are hobbed from extruded GF30 rod (not injection moulded) because the glass fibre orientation in injection moulded GF30 gears is circumferential (fibres align with the mould flow around the gear disc) which produces anisotropic tooth root properties \u2014 the hobbed gear has randomly oriented fibres at the tooth root surface, giving more isotropic (direction-independent) strength.<\/figcaption><\/figure>\n<\/section>\n<section style=\"margin: 64px 0 0;\">\n<h2 style=\"font-size: clamp(18px,2.6vw,24px);

The hobbing parameters for PA66 GF30 differ significantly from those for steel gears and even from unfilled PA66: the glass fibre reinforcement is highly abrasive to the hob cutting edges (the glass fibres \u2014 harder than the cobalt binder of the HSS hob \u2014 cause rapid flank wear on uncoated hob teeth). Korea Ever-Power uses TiAlN-coated HSS hobs for all PA66 GF30 hobbing operations \u2014 the TiAlN coating (hardness HV 3,200, oxidation temperature 900\u00b0C) resists the abrasive wear from glass fibres approximately 4\u00d7 longer than uncoated HSS, reducing the per-tooth hob cost and the frequency of hob sharpening cycles that would otherwise interrupt the production batch. Coolant for PA66 GF30 hobbing: Korea Ever-Power uses a directed air blast (not cutting fluid) to clear the glass-fibre-reinforced chip from the cutting zone \u2014 cutting fluid (water or oil-based) is not used on PA66 GF30 because it causes immediate moisture absorption at the freshly cut tooth surface, potentially causing dimensional change before the gear is measured, and because the glass fibre chips become a dense slurry with cutting fluid that is difficult to collect and filter from the machine coolant system.<\/figcaption><\/figure>\n<\/section>\n<figure style=\"margin: 0 0 28px;\"><img decoding=\"async\" style=\"width: 100%; height: auto; display: block; border-radius: 6px; border: 1px solid #d1d9e6;\" title=\"Korea Ever-Power Packaging Plastic Gear Inspection\" src=\"https:\/\/gearrack.top\/wp-content\/uploads\/2026\/07\/measuring-equipment.webp\" alt=\"Korea Ever-Power packaging plastic gear dimensional inspection quality\" \/><figcaption style=\"font-size: 12.5px; color: #64748b; margin-top: 10px; padding: 8px 14px; border-left: 4px solid #f97316; background: #fff; line-height: 1.65;\">Korea Ever-Power packaging machine plastic gear dimensional inspection \u2014 over-pin measurement of PEEK gears for hot-melt packaging systems. PEEK gears present a particular dimensional inspection challenge: the material\u2019s high thermal stability (HDT 160\u00b0C unfilled, 315\u00b0C for PEEK CF30) means that the gear dimensions are essentially unchanged by temperature variation in the measurement room \u2014 unlike nylon gears that require a 4-hour temperature conditioning period before measurement. However, PEEK\u2019s stiffness (tensile modulus 3.6 GPa unfilled, 14 GPa for CF30) means that any measurement force above approximately 0.5 N on the over-pin measurement fixture will not cause measurement artefacts from gear flex, as would be the concern for very thin-wall POM or nylon gears at small modules. Korea Ever-Power uses a spring-loaded bench micrometer at 0.2 N measuring force for all M1\u2013M3 plastic gear over-pin measurements, regardless of material \u2014 this low measurement force prevents any deformation-induced measurement error in thin-wall gears (where the tooth tips can deflect under measurement force, giving a falsely low OPM reading that would incorrectly indicate an undersize tooth). All Korea Ever-Power packaging machine plastic gears \u2014 POM, PA66 GF30, PEEK \u2014 are measured at the same fixture force and the results recorded to \u00b10.01 mm in the batch inspection report.<\/figcaption><\/figure>\n<section style=\"margin: 64px 0 0;\">\n<h2 style=\"font-size: clamp(18px,2.6vw,24px); font-weight: 800; color: #1c2330; margin: 0 0 24px; padding-bottom: 10px; border-bottom: 3px solid #2563a8;\">Frequently Asked Questions \u2014 Plastic Gears for Packaging Machines<\/h2>\n<div style=\"display: flex; flex-direction: column; gap: 12px;\">\n<div style=\"background: #fff; border: 1px solid #d1d9e6; border-radius: 4px; overflow: hidden;\">\n<div style=\"padding: 16px 20px; display: flex; align-items: flex-start; gap: 14px; background: #f7f9fc; border-bottom: 1px solid #e8edf4;\"><span style=\"background: #1c2330; color: #f97316; font-size: 10px; font-weight: 800; padding: 3px 10px; border-radius: 2px; white-space: nowrap; letter-spacing: 1px;\">Q 01<\/span><\/p>\n<p style=\"font-size: 14.5px; font-weight: bold; color: #1c2330; line-height: 1.35; margin: 0;\">Our hot-melt glue application unit in a carton sealer uses POM gears that are deforming and sticking after the machine runs at temperature for 2 hours. The gear housing reaches 130\u00b0C during operation. What should we use instead?<\/p>\n<\/div>\n<div style=\"padding: 18px 20px;\">\n<p style=\"font-size: 14.5px; color: #374151; line-height: 1.78; margin: 0;\">POM gear deformation at 130\u00b0C is predictable \u2014 POM-H begins to soften progressively above 90\u00b0C and loses 50% of its room-temperature flexural strength at 120\u00b0C. At 130\u00b0C continuous service, POM gears will creep (permanently deform) under any sustained tooth contact load. The gear is deforming first and then sticking as the softened POM surface bonds to the mating gear or housing bore when the machine cools. The correct replacement for a 130\u00b0C hot-melt glue application gear: <strong>PEEK (Polyether ether ketone)<\/strong> is the standard material for hot-melt system gears at up to 200\u00b0C continuous temperature. PEEK retains more than 60% of its room-temperature flexural strength at 150\u00b0C (flexural strength at 150\u00b0C approximately 100 MPa vs 170 MPa at 23\u00b0C) and does not creep measurably at 130\u00b0C under light packaging machine gear loads. PEEK also has excellent chemical resistance to the polyurethane (PU) and ethylene vinyl acetate (EVA) hot-melt adhesives used in carton sealing \u2014 it does not swell, soften, or bond to the hot-melt adhesive at the gear surface. Korea Ever-Power PEEK gears for hot-melt packaging systems: M1.5\u2013M3, machined from Victrex PEEK 450G rod stock (natural grade, no filler \u2014 unfilled PEEK is preferred over PEEK GF30 for hot-melt applications because the glass fibres can become exposed at the tooth surface under wear and can act as nucleation sites for hot-melt adhesive adhesion). Available in the natural tan colour or black (carbon-black pigmented PEEK \u2014 the black pigment reduces UV degradation for packaging lines with UV-curing adhesive stations). Lead time for standard PEEK gear sizes: 12\u201318 working days. Note: PEEK costs approximately 15\u201320\u00d7 POM per kg, but in packaging machine gear applications the gear volume is small and the service life is dramatically longer \u2014 the total cost per machine service life is typically lower with PEEK than POM for any application above 100\u00b0C ambient gear temperature.<\/p>\n<\/div>\n<\/div>\n<div style=\"background: #fff; border: 1px solid #d1d9e6; border-radius: 4px; overflow: hidden;\">\n<div style=\"padding: 16px 20px; display: flex; align-items: flex-start; gap: 14px; background: #f7f9fc; border-bottom: 1px solid #e8edf4;\"><span style=\"background: #1c2330; color: #f97316; font-size: 10px; font-weight: 800; padding: 3px 10px; border-radius: 2px; white-space: nowrap; letter-spacing: 1px;\">Q 02<\/span><\/p>\n<p style=\"font-size: 14.5px; font-weight: bold; color: #1c2330; line-height: 1.35; margin: 0;\">We need to replace the steel drive gears in our labelling machine with plastic gears to reduce noise and vibration. The steel gears are M2, 40T, face width 20 mm, running at 800 RPM, driving a label roll take-up spool. What plastic material and any module change is needed?<\/p>\n<\/div>\n<div style=\"padding: 18px 20px;\">\n<p style=\"font-size: 14.5px; color: #374151; line-height: 1.78; margin: 0;\">Replacing M2 steel label take-up drive gears with plastic \u2014 noise analysis and design recommendation: <strong>Current steel gear transmit load estimate:<\/strong> a label roll take-up spool at 800 RPM driving a 300 g label roll at 150 mm spool radius produces a tangential load of approximately F_t = T\/r = (0.3 kg \u00d7 9.81 m\/s\u00b2 \u00d7 0.15 m) \/ 0.02 m = 22 N at the M2 gear pitch circle. This is a very light load \u2014 well within the capability of any engineering plastic at M2. <strong>Material recommendation:<\/strong> POM-H with 2% PTFE additive (or standard POM-H if the label adhesive exposure is minimal). The PTFE additive provides dry-run capability in case the label machine&#8217;s periodic cleaning removes the light lubrication that the steel gears previously had. No module change needed \u2014 M2 in POM-H has a tooth bending fatigue strength sufficient for 22 N tangential load with a safety factor above 5.0 at the 10\u2077 cycle design life. The tooth contact fatigue (pitting) life is also comfortable at this light load. <strong>NVH improvement expected:<\/strong> the label take-up drive at M2, 40T, 800 RPM produces a gear mesh frequency of 800\/60 \u00d7 40 = 533 Hz. At this frequency, POM gears produce approximately 55\u201360 dB(A) at 1 metre versus 66\u201370 dB(A) for steel DIN 7 gears \u2014 a 8\u201312 dB(A) improvement, consistent with the general plastic gear noise advantage. <strong>Design note on bore tolerance:<\/strong> for the replacement POM gears to fit the existing shaft, the bore H7 tolerance must be maintained. POM machines to a stable bore diameter without the spring-back effect that makes some nylon gears difficult to bore to precise tolerance \u2014 Korea Ever-Power holds \u00b10.015 mm on bore diameter for POM labeller gears up to 30 mm bore diameter, which is adequate for H7 fit on the existing label take-up shaft without additional reaming after fitting.<\/p>\n<\/div>\n<\/div>\n<div style=\"background: #fff; border: 1px solid #d1d9e6; border-radius: 4px; overflow: hidden;\">\n<div style=\"padding: 16px 20px; display: flex; align-items: flex-start; gap: 14px; background: #f7f9fc; border-bottom: 1px solid #e8edf4;\"><span style=\"background: #1c2330; color: #f97316; font-size: 10px; font-weight: 800; padding: 3px 10px; border-radius: 2px; white-space: nowrap; letter-spacing: 1px;\">Q 03<\/span><\/p>\n<p style=\"font-size: 14.5px; font-weight: bold; color: #1c2330; line-height: 1.35; margin: 0;\">What are the minimum order quantity and lead times for packaging machine plastic gears, and does Korea Ever-Power offer annual supply agreements for packaging machine OEM builders?<\/p>\n<\/div>\n<div style=\"padding: 18px 20px;\">\n<p style=\"font-size: 14.5px; color: #374151; line-height: 1.78; margin: 0;\">Korea Ever-Power&#8217;s packaging machine plastic gear supply structure: <strong>Machined (any quantity above minimum):<\/strong> minimum 10 pieces per order for machined POM, PA66 GF30, or PEEK gears at M1.5\u2013M5. Lead time 10\u201318 working days for standard materials; 15\u201322 working days for PEEK. The minimum order cost for machined plastic gears is essentially the setup and material cost \u2014 for small packaging machine gear sizes (M2, 30 mm OD), 10 pieces can be cut from a single rod of POM in 2\u20133 hours of CNC time. <strong>Injection moulded (high volume):<\/strong> for M1\u2013M3 gears ordered above 500 pieces per order, injection moulding from Korea Ever-Power\u2019s multi-cavity tooling (where the tool exists) is more economical than machining \u2014 the injection moulded piece price is typically 40\u201360% below the machined price at 1,000 pieces. Korea Ever-Power holds tooling for approximately 200 common packaging machine plastic gear sizes (the most frequently ordered M1\u2013M3 gear sizes for major labelling machine and wrapper brands). If the required gear is not in the tooling library, new tooling is designed and manufactured in approximately 25\u201335 working days at a one-time tooling charge, after which injection moulded supply has a lead time of 12\u201318 working days per order. <strong>Annual OEM supply agreements:<\/strong> Korea Ever-Power offers packaging machine OEM builders annual supply agreements that cover: (a) a committed annual volume (e.g. 10,000 pieces per year of a specific gear) at a fixed unit price; (b) a maximum call-off response time (typically 5\u20138 working days for call-offs within the annual volume); (c) consignment stock at Korea Ever-Power\u2019s warehouse (typically 3 months of forecast demand) for immediate dispatch on call-off without manufacturing lead time; and (d) a first-article acceptance test at the start of each production year, confirming dimensional compliance with the drawing before the annual production run. Annual OEM supply agreements are the preferred supply model for packaging machine builders who produce 50+ machines per year with the same plastic gear specifications, as they eliminate the lead time uncertainty of individual purchase orders and provide price certainty for the machine builder\u2019s component cost forecast.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n<section style=\"margin: 72px 0 0;\">\n<div style=\"text-align: center;
