UHMWPE (Ultra High Molecular Weight Polyethylene) customized conveyor fittings are the optimal solution for conveyor shop production.
What are UHMWPE conveyor parts?
Faster wear and tear of factory conveyor equipment leads to frequent replacement of parts, increasing operating costs. Workshop noise affects the environment of employees, and even interrupt production due to friction and jamming.UHMWPE conveyor parts are used to mitigate the friction and noise problems of conveyor workshop production parts.
UHMWPE material core characteristics
UHMWPE, or ultra-high molecular weight polyethylene, is a high-performance engineering plastic, and its core characteristics are highly compatible with conveyor friction and noise reduction needs, which is the key to its superiority over traditional materials.
The core characteristics of UHMWPE include:
Low coefficient of friction: 0.1-0.2 in contact with steel, as low as 0.05-0.1 in some scenarios, with self-lubricating properties without additional lubrication.
Ultra-high wear resistance: 6-8 times that of carbon steel and stainless steel.
Excellent impact resistance: -260 ℃ still maintain the toughness.
Lightweight: density 0.93g/cm³, only 1/8 of carbon steel.
The performance of UHMWPE plastic is closely related to the molecular weight, and it is preferred to choose more than 3.5 million molecular weight material, which has more outstanding performance of friction reduction, abrasion resistance, and impact resistance, and is suitable for high load operation.
What are the UHMWPE conveyor components?
UHMWPE conveyor parts are rich in variety, designed for different operation of conveyor, with the core objectives of reducing friction, lowering noise, protecting equipment, improving efficiency, and adapting to different industrial scenarios.
Wear Strips & Pads
Wear Strips & Pads are the most basic and core friction and noise reduction parts, which are installed at the contact point between the frame and moving parts, and directly act on the friction source.
The function of UHMWPE wear strips is to reduce the direct friction between chains, belts and racks, stabilize the belt trajectory, avoid friction-generated vibration and noise, and at the same time reduce the wear and tear of the equipment and energy consumption.
Guide Rails & Chain Guides
The low friction surface of UHMWPe guide rails and chain guides ensures smooth running of chains and belts, avoids friction resistance and vibration noise caused by offset jamming, and prevents overheating and damage of components.
These UHMWPE components are used in food processing, beverage bottling and other industries that require high hygiene and low noise levels, and in mining and other scenarios where anti-static and flame-retardant guides can be customized to combine safety with friction and noise reduction.
Conveyor Sprockets & Worm Screws
Conveyor sprockets and worm screws are the core components of power transmission, and the smoothness of operation directly affects the noise and friction loss.
The smooth surface of UHMWPE plastic material realizes silent transmission, greatly reduces the friction and impact noise of gear meshing, and changes the noisy problem of traditional metal sprockets.
Bushings, Bearings & Crowner Discharge Parts
Suitable for conveyor rotation and discharge, UHMWPE bushings and bearings require no additional lubrication, dramatically reducing rotational friction and avoiding the harsh noise associated with metal parts rubbing together, making them ideal for harsh industrial environments.
The crown shaped unloading part is suitable for high speed bottling line, which reduces material friction and collision noise, protects the material and improves the efficiency, and the extended rollers can also reduce the noise through low friction characteristics.
UHMWPE vs Metal Conveyor Parts
Traditional metal parts have obvious shortcomings in friction and noise control, and there is a significant gap between them and UHMWPE parts, the specific comparisons are as follows, which is convenient for enterprises to choose quickly.
Core dimension comparison
Friction coefficient: UHMWPE fittings 0.1-0.2 (some as low as 0.05-0.1), metal fittings 0.3-0.5, easy to produce friction loss and noise.
Operation noise: UHMWPE fittings run quietly (≤75dB), metal fittings impact, friction noise is obvious, affecting the workshop environment.
Maintenance requirements: UHMWPE parts are lubrication-free and easy to clean, while metal fittings need regular lubrication, and insufficient lubrication will aggravate the friction noise and higher maintenance cost.
Weight and installation: UHMWPE parts are lightweight and easy to install, while metal fittings are bulky and cumbersome, increasing the load of equipment.
Wear resistance and life: UHMWPE fittings life is several times that of metal fittings, wear-resistant and reduce wear and tear noise, metal fittings are easy to wear and tear, noise increases.
Comparison with common engineering plastics
Compared with PE, PVC and other common engineering plastics, UHMWPE fittings have obvious advantages of low friction and high wear resistance.
Ordinary engineering plastics have high friction coefficient and poor abrasion resistance, which can’t adapt to high load friction scene for a long time, and easy to wear and generate noise, while UHMWPE can keep the friction and noise reduction effect for a long time.
