Frequently Asked Questions about Nylon Rods

Nylon rod is a type of thermoplastic rod that is made from nylon, a synthetic polymer that has high strength, toughness, wear resistance, and low friction. Nylon rod can be cast or extruded into various shapes and sizes, and can be modified with additives to enhance its properties. Nylon rod is used for many industrial and commercial applications, such as bushings, bearings, gears, sprockets, wheels, rollers, screws, and 3D printing.

Some of the advantages of Nylon Rods over other materials such as metal or wood are:

  • high mechanical strength, toughness, wear resistance, and low friction, which make them suitable for applications that require durability and smooth movement.
  • good chemical resistance and can withstand corrosion and abrasion from various substances, which make them ideal for harsh environments and chemical processing.
  • low thermal conductivity and high heat resistance, which make them able to perform well in high temperature conditions and reduce heat transfer to other parts.
  • low density and weight compared to metal, which make them easier to transport, handle, and install, and also reduce fuel consumption and noise in vehicles.
  • good electrical insulation and low flammability, which make them safe to use around sensitive electrical components and fire hazards.
  • high flexibility and elasticity, which make them able to absorb shock and vibration and adapt to different shapes and sizes.
  • easy machinability and fabricability, which make them convenient to cut, drill, tap, or machine into various forms and dimensions.
  • self-lubricating properties, which make them reduce friction and wear of mating parts and eliminate the need for external lubricants.
  • good recyclability and biodegradability, which make them environmentally friendly and reduce waste disposal costs.

There are different types and grades of Nylon Rods that differ in their molecular structures, properties, and applications. Some of the common types and grades are:

  • Nylon 6 - This type of nylon is made by a liquid casting process and has high tensile and impact strength, machinability, and elasticity. It can be modified with glass or carbon fibers to improve its performance. It is used for applications such as food processing equipment, bushings, bearings, gears, and sprockets.
  • Nylon 6/6 - This type of nylon is made by a thermoplastic extrusion process and has higher tensile strength and stiffness, better dimensional stability, and higher melting point than Nylon 6. It has good chemical resistance and low flammability. It can be enhanced with fillers, fibers, lubricants, and impact modifiers to increase its strength and stiffness. It is used for applications such as household appliances, electrical components, fasteners, and 3D printing.
  • Nylon MDS - This type of nylon is a version of Nylon 6/6 with the addition of fine particles of MDS (molybdenum disulfide). This improves the load-bearing capacity and impact resistance of the material while preserving its self-lubrication level. It has high wear resistance and durability and is used for applications that are exposed to high mechanical stresses such as machinery components.
  • Oil-Filled Nylon - This type of nylon is a version of Nylon 6 or Nylon 6/6 with the addition of oil to reduce friction and wear. It has improved sliding properties and reduced noise. It is used for applications that require smooth movement such as gears, bearings, bushings, and rollers.
  • Glass-Filled Nylon - This type of nylon is a version of Nylon 6 or Nylon 6/6 with the addition of glass fibers to increase its strength, stiffness, and heat resistance. It has improved dimensional stability and reduced moisture absorption. It is used for applications that require high rigidity and thermal stability such as structural parts, valves, pumps, and housings.

To choose the right size and shape of Nylon Rods for your project, you need to consider the following factors:

  • The dimensions and tolerances of the part you want to make or replace. You should measure the length, diameter, thickness, and any other relevant features of the part and compare them with the available sizes of Nylon Rods. You should also check the dimensional stability and shrinkage of the Nylon Rods under different conditions such as temperature, moisture, and stress.
  • The mechanical and thermal properties of the Nylon Rods. You should select the type and grade of Nylon Rods that match or exceed the requirements of your application in terms of strength, stiffness, impact resistance, heat resistance, wear resistance, and friction. You should also consider the effects of additives such as fillers, fibers, lubricants, and modifiers on the properties of the Nylon Rods.
  • The machinability and fabricability of the Nylon Rods. You should choose the Nylon Rods that are easy to cut, drill, tap, or machine into the desired shape and size. You should also consider the tools and techniques that are suitable for working with Nylon Rods such as saws, lathes, mills, routers, drills, taps, dies, etc. You should also follow the recommended cutting speeds, feeds, and depths for Nylon Rods to avoid overheating or cracking.
  • The cost and availability of the Nylon Rods. You should compare the prices and availability of different types and grades of Nylon Rods from different suppliers and manufacturers. You should also consider the shipping costs and delivery times of the Nylon Rods. You should also check if there are any custom options or services available for Nylon Rods such as cutting to size, machining, fabrication, welding, finishing, etc.

Nylon Rods are easy to cut, drill, tap, or machine with conventional tools and techniques. Here are some tips for working with Nylon Rods:

  • Use sharp and clean tools to avoid tearing or chipping the material. You can use high-speed steel or carbide tools for cutting Nylon Rods.
  • Use low to moderate cutting speeds and feeds to avoid overheating or melting the material. You can use water or oil as a coolant or lubricant to reduce friction and heat generation.
  • Use a rigid and stable setup to avoid vibration or deflection of the material. You can use clamps, vises, or fixtures to secure the Nylon Rods during machining.
  • Use a center drill or a pilot hole to start drilling Nylon Rods. You can use twist drills, spade drills, or reamers for drilling Nylon Rods. You should clear the chips frequently to avoid clogging the drill bit or the hole.
  • Use a taper tap or a plug tap to start tapping Nylon Rods. You can use hand taps or machine taps for tapping Nylon Rods. You should use a suitable tap wrench or holder to apply even pressure and avoid breaking the tap. You should also use a thread lubricant to reduce friction and wear.
  • Use a fine-toothed saw blade or a band saw to cut Nylon Rods. You can use a hacksaw, a circular saw, or a table saw for cutting Nylon Rods. You should support the Nylon Rods well and avoid excessive pressure or speed when cutting. You should also use a coolant or lubricant to reduce heat and friction.

There are different methods for joining or bonding Nylon Rods to other materials or to themselves, depending on the type of material, the strength of the bond, and the application. Some of the common methods are:

  • Plastic welding - This method involves melting the surface of the Nylon Rods and the other material by using heat or chemicals, and then pressing them together until they fuse. This method creates a strong and durable bond that is resistant to water and solvents. However, this method requires special equipment and skills, and may damage or deform the materials.
  • Hot glue - This method involves applying hot glue to the surface of the Nylon Rods and the other material, and then pressing them together until they cool down. This method works well for bonding Nylon to Nylon, as Nylon is a thermoplastic that can be heated and shaped without degrading. The hot glue melts the Nylon and bonds to its surface, creating a strong bond. However, this method may not work well for bonding Nylon to other materials that have different melting points or thermal expansion rates.
  • Cyanoacrylate adhesive - This method involves applying a thin layer of cyanoacrylate adhesive (also known as super glue) to the surface of the Nylon Rods and the other material, and then pressing them together until they cure. This method works well for bonding Nylon to various materials such as metal, wood, rubber, leather, etc. However, this method may not provide a long-term bond for some types of Nylon that have high moisture absorption or slip additives. To improve the bond strength, an adhesion promoter or an activator can be used before applying the adhesive.
  • Epoxy adhesive - This method involves mixing a two-part epoxy resin and hardener, and then applying it to the surface of the Nylon Rods and the other material. The epoxy adhesive then cures by chemical reaction, creating a strong and rigid bond that can withstand high temperatures and pressures. However, this method may not provide a flexible bond for some applications that require movement or vibration. To improve the bond strength, the surface of the Nylon Rods can be roughened or abraded before applying the adhesive.
  • Polyurethane adhesive - This method involves applying a one-part or two-part polyurethane adhesive to the surface of the Nylon Rods and the other material. The polyurethane adhesive then cures by moisture or chemical reaction, creating a strong and flexible bond that can resist impact and abrasion. However, this method may not provide a water-resistant bond for some applications that require exposure to moisture or humidity. To improve the bond strength, the surface of the Nylon Rods can be cleaned or primed before applying the adhesive.
  • Acrylic adhesive - This method involves applying a one-part or two-part acrylic adhesive to the surface of the Nylon Rods and the other material. The acrylic adhesive then cures by UV light or chemical reaction, creating a strong and fast bond that can resist heat and solvents. However, this method may not provide a UV-resistant bond for some applications that require exposure to sunlight or UV light. To improve the bond strength, an adhesion promoter or an activator can be used before applying the adhesive.

To store and handle Nylon Rods properly, you need to consider the following factors:

  • The moisture and temperature of the storage environment. Nylon Rods are hygroscopic, which means they absorb moisture from the air. This can affect their dimensions, weight, strength, and stiffness. To prevent moisture absorption, you should store Nylon Rods in a dry and cool place, away from direct sunlight, heat sources, and water sources. You can also seal them in plastic bags with desiccants or use a dehumidifier to control the humidity level.
  • The mechanical stress and deformation of the Nylon Rods. Nylon Rods are flexible and elastic, which means they can bend or stretch under load or pressure. This can cause permanent deformation or damage to the Nylon Rods. To prevent mechanical stress and deformation, you should store Nylon Rods in a horizontal position, supported by racks or shelves that prevent sagging or bending. You should also avoid stacking or piling up Nylon Rods on top of each other or placing heavy objects on them.
  • The chemical exposure and corrosion of the Nylon Rods. Nylon Rods have good chemical resistance to most common substances, but they can still be affected by some strong acids, bases, oxidizers, solvents, or fuels. These chemicals can cause discoloration, swelling, cracking, or degradation of the Nylon Rods. To prevent chemical exposure and corrosion, you should store Nylon Rods in a clean and well-ventilated place, away from sources of contamination or spillage. You should also use protective gloves and goggles when handling Nylon Rods that may have come into contact with chemicals.

The temperature and moisture limits of Nylon Rods depend on the type and grade of Nylon, but generally, they have the following ranges and effects:

  • The temperature range of Nylon Rods is from -40°F (-40°C) to 194°F (90°C) for continuous use, and up to 300°F (149°C) for intermittent use. Higher temperatures can cause Nylon Rods to melt, deform, or degrade. Lower temperatures can cause Nylon Rods to become brittle and crack.
  • The moisture range of Nylon Rods is from 0% to 10% relative humidity. Higher moisture levels can cause Nylon Rods to absorb water, which can affect their dimensions, weight, strength, stiffness, and electrical properties. Lower moisture levels can cause Nylon Rods to dry out, which can reduce their flexibility and impact resistance.
  • The performance and durability of Nylon Rods are influenced by both temperature and moisture, as well as other factors such as stress, load, friction, chemical exposure, UV light, etc. To optimize the performance and durability of Nylon Rods, it is important to select the appropriate type and grade of Nylon for the specific application, and to follow the recommended storage and handling guidelines.

To clean and maintain Nylon Rods, you need to follow these steps:

  • Remove any dirt, dust, or debris from the surface of the Nylon Rods with a soft brush or cloth. You can also use compressed air to blow away any loose particles.
  • Wipe the surface of the Nylon Rods with a damp cloth or sponge soaked in mild soap and water. You can also use a mild detergent or a plastic cleaner that is compatible with Nylon. Do not use harsh chemicals, solvents, or abrasives that may damage the Nylon Rods.
  • Rinse the surface of the Nylon Rods with clean water to remove any soap or detergent residue. You can also use a spray bottle or a hose to rinse the Nylon Rods.
  • Dry the surface of the Nylon Rods with a clean cloth or towel. You can also use a hair dryer or a heat gun to speed up the drying process. Do not use excessive heat that may warp or melt the Nylon Rods.
  • Apply a thin layer of wax or polish to the surface of the Nylon Rods to protect them from scratches and stains. You can also use a silicone spray or a plastic conditioner that is compatible with Nylon. Do not use oil or grease that may attract dirt and dust.
  • Store the Nylon Rods in a dry and cool place, away from direct sunlight, heat sources, and water sources. You can also seal them in plastic bags with desiccants or use a dehumidifier to control the humidity level.

Some of the common problems or issues that may arise when using Nylon Rods are:

  • Surface swirls - These are cosmetic defects that appear as streaks or patterns on the surface of Nylon Rods, especially when they are glass-filled. They are caused by the different flow rates and cooling rates of the Nylon and the glass fibers in the mold. To avoid or solve this problem, you can use a Nylon grade that has a rubber component that covers up the swirls, such as DuPont’s Zytel. You can also use a different type of Nylon, such as Nylon 6 or Nylon 6/6/6, that has less tendency to form swirls. You can also adjust the mold temperature, injection speed, and packing pressure to optimize the flow and cooling of the material.
  • Dents - These are surface defects that appear as depressions or craters on the surface of Nylon Rods. They are caused by excessive shrinkage of the material during cooling, especially in thick or uneven sections. To avoid or solve this problem, you can use a gate and runner system that is large enough to allow sufficient material flow and pressure. You can also reduce the material temperature, mold temperature, and injection speed to minimize shrinkage. You can also increase the injection volume, holding time, and holding pressure to compensate for shrinkage.
  • Warping - This is a dimensional defect that occurs when Nylon Rods bend or twist out of shape due to uneven shrinkage or stress. It is caused by factors such as high material temperature, high mold temperature, high injection speed, high injection pressure, low cooling rate, low clamping force, poor mold design, or poor part design. To avoid or solve this problem, you can reduce the material temperature, mold temperature, injection speed, and injection pressure to minimize stress and shrinkage. You can also increase the cooling rate, clamping force, and cycle time to ensure uniform cooling and solidification. You can also improve the mold design and part design to avoid thick or thin sections, sharp corners, or complex geometries that may cause warping.

Some of the safety precautions and regulations that you need to follow when working with Nylon Rods are:

  • Wear appropriate personal protective equipment (PPE) such as gloves, goggles, masks, and aprons to prevent contact with hot or molten Nylon, dust or fumes from machining or welding, or chemicals from cleaning or bonding.
  • Use proper ventilation and exhaust systems to remove dust or fumes from the work area and prevent inhalation or exposure to harmful substances.
  • Follow the manufacturer’s instructions and specifications for handling, storing, and using Nylon Rods and related products. Read and understand the material safety data sheets (MSDS) and labels for Nylon Rods and any additives, solvents, adhesives, or cleaners that are used with them.
