Machining is a critical manufacturing process for producing plastic parts and products. The machining behavior of plastics can vary widely depending on the material. Two of the most common thermoplastics, POM and nylon, have markedly different machining characteristics. Understanding these differences is imperative for efficient, high-quality machining.

POM Machining Characteristics: POM is renowned for its stellar machinability. It machines like a metal, holding tight dimensional tolerances without distortion. POM’s thermal conductivity prevents localized heat buildup, allowing high speeds and feeds. This results in very low cutting forces, power consumption and tool wear. POM’s crisp edges and ability to capture fine details enable precision machined components like gears or bearings. Surface finishes down to 0.2 microns are possible with POM machining.

Nylon Machining Characteristics: In contrast to POM, nylon is notoriously more difficult to machine precisely. Its lower thermal conductivity leads to melting, smearing, and gumming on cutting tools. Nylon’s tendency to grab and stick to tools accelerates tool wear. Higher cutting forces are required, increasing power needs. The additional heat generated can limit cutting speeds and feeds. While dimensionally stable nylons are available, achieving tight tolerances is still challenging. The moderate surface finish of nylon usually requires post-machining operations.

Machining Recommendations: Adjusting parameters like tool geometry, feed rates, depth of cut and use of coolants can aid nylon machining. HSS tooling with sharp cutting edges and high positive rake angles perform better. Flood cooling is suggested to prevent melting. Roughing and finishing operations may need to be optimized differently for nylon versus POM. POM can often be machined in a single pass.

Application Examples: For precision components like gears or bearings, POM’s stellar dimensional stability would be highly beneficial. Where dimensional accuracy is less critical, such as housings or enclosures, nylon may be suitable. In all cases, the plastic’s machinability must be matched to the part requirements.

In summary, POM’s excellent thermal conductivity and stability result in superior machining behavior over nylon. POM allows higher speeds and precision while reducing tool wear and power needs. Understand your plastic’s machinability characteristics relative to your application requirements when selecting a material. With the right techniques, even challenging plastics like nylon can be machined successfully.

Nylon is a widely used engineering plastic that has excellent strength, stiffness, wear resistance and chemical resistance. Nylon sheets and bars are a convenient machining form that can be used to manufacture various parts and components, such as bearings, gears, sliders, washers and more. This article will show you how to choose the right wear-resistant nylon sheets and bars, as well as their main features and applications.

What are Wear-Resistant Nylon Sheets and Bars

• Nylon is a synthetic polymer that can be classified into different types based on its molecular structure and properties. The most common types are nylon 6, nylon 6/6, nylon 6/12 and nylon 12.
• Wear-resistant nylon sheets and bars are made by casting or extruding molten nylon into flat or round shapes. They have a smooth surface and uniform dimensions that can be easily cut, drilled, tapped or turned.
• Wear-resistant nylon sheets and bars have many advantages over other plastics or metals, such as high mechanical strength, low friction coefficient, good abrasion resistance, low moisture absorption, good thermal stability and electrical insulation. They also have some drawbacks, such as high water absorption, low impact resistance, poor UV resistance and flammability.

How to Choose Wear-Resistant Nylon Sheets and Bars

• Depending on your application requirements, you can choose from different types of wear-resistant nylon sheets and bars that have enhanced properties by adding fillers or additives. Some common types are oil-filled, molybdenum disulphide-filled (MOS2), glass-filled and heat-stabilized nylons.
• Different types of wear-resistant nylon sheets and bars have different physical properties, such as density, hardness, tensile strength, elongation, modulus of elasticity, melting point, thermal expansion coefficient, color and more. You should compare these properties to select the best type for your application.
• Some tips and suggestions for choosing wear-resistant nylon sheets and bars are: consider the load, speed, temperature and environment of your application; select the appropriate size and thickness of the sheets or bars; use proper machining tools and techniques; avoid excessive heat or moisture exposure; apply lubrication if needed.

Applications of Wear-Resistant Nylon Sheets and Bars

• Wear-resistant nylon sheets and bars can be used in various industries for different applications that require strength, stiffness and wear resistance. Some examples are: machinery, automotive, chemical, textile, food processing, medical and more.
• Wear-resistant nylon sheets and bars can produce high-quality and high-performance parts and components that can reduce noise, vibration, friction and maintenance costs. Some examples are: bearings, bushings, rollers, gears, sprockets, pulleys, cams, washers, spacers, guides, slides and more.
• Wear-resistant nylon sheets and bars have a great potential for future development as they can meet the increasing demands for lightweight, durable and eco-friendly materials. Some trends are: developing new types of nylons with improved properties; using recycled or biodegradable nylons; creating smart or functional nylons with sensors or actuators.
