Low Friction Wear Resistance POM Plastic CNC Machining Parts For Bearings Gears
POM (Polyoxymethylene) is one of the commonly used plastic CNC machining roperties. The typical applications of machining Delrin include bushings, fittings, safety restraints, and screws.
Manufacturers in most industries often use Delrin 150 and 570 for applications that require higher dimension stability and longer lifespan. However, it corrodes quickly in acids even though this plastic provides good resistance to chemical, weather, heat, and impacts.
What Is POM Material?
POM is an engineering plastic with several beneficial properties. Some of its properties include exceptional hardness, strength, and rigidity. Despite its capability of being made in various hues, its high crystalline content gives it a naturally opaque white appearance. POM has a density of between 1.410 and 1.420 g/cm³.
POM plastic is frequently used to create precise parts requiring dimensional stability, high rigidity, and low friction. This low friction makes POM ideal for rotating or sliding components such as bushings, bearings, and gears.
Like many other synthetic POM polymers, it is produced by several chemical firms using slightly varying formulae and sold under many brand names like Celcon, Tenac, Duracon, etc.
Properties Of POM Plastic
The high-performance engineering plastic polyoxymethylene (POM) is widely used in many sectors. It qualifies for various applications due to its assortment of distinctive properties.
Low Friction and Wear Resistance
POM plastic stands out for having a low coefficient of friction, which helps to explain why it has such outstanding self-lubricating properties. Since there is less wear and more efficiency overall, fluid sliding or rotational movements are made possible by the reduced frictional resistance.
Chemical Resistance
POM is ideal for making products in constant contact with chemical solvents, such as pump parts, seals, and fuel system components. This is primarily due to POM plastic’s remarkable resistance to various chemicals, solvents, and fuels. It can resist contact with numerous organic chemicals, alcohols, oils, and greases without significantly deteriorating.
Low Water Absorption and Dimensional Stability
POM plastic has remarkable dimensional stability and keeps its size and shape even in changing humidity and temperature conditions. As a result of its minimal water absorption, it is not susceptible to moisture-related problems like swelling, warping, and other dimensional changes.
Applications requiring accurate tolerances, as well as consistent efficiency, also depend heavily on POM’s dimensional stability.
Easy Machinability
The simplicity with which POM plastic may be machined makes precision and effective manufacturing procedures possible. It is easily molded, machined, turned, and drilled, making it easy to make intricate pieces and complex designs. Because of this characteristic, POM resin is frequently chosen for applications requiring complex geometries and great precision.
Excellent Creep / Impact Resistance
Excellent creep resistance is exhibited by POM plastic, which means it can withstand sustained mechanical stress without deforming. Due to this characteristic, POM components can continue functioning properly even when continuously subjected to loads or strains.
Applications Of POM Parts
POM parts find use across a diverse range of industries due to their durability and other beneficial properties. Below are the different applications of POM parts.
Electrical and Electronic Parts
POM is electrically insulating. Hence, it can be used to produce switches and connectors for protecting electronic parts.
Medical Devices
Due to POM’s biocompatibility, it is utilized in the medical industry to make surgical tools, medication systems for administration, and other medical equipment.
Automobiles
POM plastic is used in several interior and exterior automotive parts, including fuel system components and window lift gears.
Household items
POM plastic components are frequently used to create handles, buckles, zippers, and other parts for household items and appliances.
Comparative Analysis: POM vs. Other Engineering Plastics in CNC Machining
