As per our Shipping and Returns Policy, custom cuts and fabricated parts are non-returnable. If you need an over- or undersized item, note it under "Comments" during Checkout. Cut-to-size orders have an acceptable cut tolerance of 1/8" (0.125"), so clarify if the adjustment is to be made on the (+) or (-) side of the saw blade.Please review our full return and shipping policy here.
Measure Twice, Cut Once
Since custom cuts and fabricated parts are non-refundable, be very careful while measuring your dimensions. As each cut is nominal, even the slightest miscalculation could be costly.
How to Use a Measuring Tape
Extend your tape measure several inches to find the 1 and 2 inch markers. In between the inch markers you’ll find 16 equally spaced tick marks.
Measure by counting the increments beyond the nearest inch. As the increments decrease, so does the length of the mark. For example, 1/2" has a bigger mark than 1/4" which has a bigger mark than 1/8". The smallest mark follows at 1/16". Please be aware that some measuring tapes may have even smaller increments.
Features of a Measuring Tape: Sliding End Hook
The sliding end hook is designed for two different types of measurements. An outside measurement (where the hook of the tape hangs over an edge), requires the hook to slide out a bit to account for the thickness of the material. When making an inside measurement (where the hook will push up against a surface), the clip slides in, again, accounting for its thickness. The measuring tape self-adjusts to guarantee an accurate measurement (as far as the tape is concerned).
Sanitizing Acrylic and Polycarbonate Sheet [X]
Acrylic and Polycarbonate Sneeze Guards and like products require special care while cleaning and disinfecting. To maintain the optical clarity of sneeze guards and other acrylic or polycarbonate items, use an acrylic or polycarbonate safe cleaner like Novus Plastic Polish #1, Brillianize Plastic Cleaner, or a mild soap solution.
Please reference the following compatible cleaners when DISINFECTING acrylic and polycarbonate items. The use of commonly available commercial alcohol or ammonia-based disinfectants may cause crazing and damage.
Cast Nylon 6 Sheet: Durable, Wear-Resistant Replacement for Metal
Natural Cast Nylon 6 is a highly crystalline, dimensionally stable engineering thermoplastic. Known for its exceptional load-bearing capacity and superior wear resistance, it is the industry standard for replacing heavy, noisy metal components like brass, bronze, and steel.
Cast Nylon excels as a metal replacement: it effectively eliminates metal-on-metal wear, provides significant noise reduction, and extends the operational life of components. From precision gears to close-tolerance bearings, Cast Nylon reduces part weight while offering exceptional fatigue endurance and rigidity.
Cast Nylon 6 provides significantly lower internal stress and better dimensional stability compared to extruded nylon grades. It is the correct choice if you need:
High Load Capacity: Exceptional modulus of elasticity and strength make it ideal for structural and load-bearing components.
Low Coefficient of Friction: The smooth surface minimizes heat and wear in dynamic, moving parts like sprockets and rollers.
Metal Replacement: Reduces equipment weight and dampens noise vibration when replacing traditional brass, bronze, or steel parts.
Chemical Resistance: Highly resistant to common industrial solvents, hydrocarbons, and alkalis.
FDA Compliant: Natural (unfilled) Cast Nylon is approved for safe food contact in processing applications.
Cast Nylon 6 vs. Extruded Nylon 6/6: Which Do You Need?
While both are highly capable engineered mechanical plastics, their manufacturing processes dictate their best use cases.
Choose Cast Nylon 6 (This Sheet) for larger parts, thicker cross-sections, and tighter tolerances. The casting process yields lower internal stress, providing better dimensional stability and slightly higher crystallinity for improved wear resistance.
Choose Extruded Nylon 6/6 if you need thinner materials or smaller diameter rods. It is highly versatile but retains higher internal stress, which can lead to warping during heavy machining if not properly managed.
Fabrication & Machining
Cast Nylon 6 is highly machinable and yields excellent surface finishes when using sharp, high-speed steel (HSS) or carbide tooling with generous clearances.
Note on Moisture: Nylon is hygroscopic. In wet or high-humidity environments, it will absorb moisture and can dimensionally swell up to 2-3%. Design your tolerances to account for this if the material will be submerged.

Technical Performance
Nylon 6 is formulated for applications requiring a unique combination of high load-bearing capacity, metal-like strength, and exceptional wear resistance.
Load Bearing Capacity: High modulus of elasticity and yield strength allow it to effectively replace heavy metal components like brass and bronze.
Wear & Fatigue: Exceptional fatigue endurance and wear resistance in sliding, oscillating, or rotating applications.
Friction Coefficient: Low coefficient of friction reduces the need for external lubrication in moving parts, extending equipment lifespan.
Key Properties
Dimensional Stability: The casting process lowers internal stress compared to extruded nylon, allowing for tighter machining tolerances on large parts.
FDA Compliant: Natural (uncolored) Cast Nylon 6 is approved for direct food contact and processing applications.
Sound Dampening: Viscoelastic properties absorb shock and vibration, significantly reducing operating noise compared to metal gears.
Chemical Resistance: Highly resistant to common alkalis, hydrocarbons, and industrial solvents.
Hygroscopic Nature: Absorbs moisture from its environment, which increases impact toughness but requires calculating for dimensional swelling in wet conditions.
Common Industrial Applications
Power Transmission: Heavy-duty gears, sprockets, and sheaves that require high strength and quiet operation.
Bearings & Bushings: High-load, low-speed bearings that outlast traditional bronze and brass alternatives while reducing weight.
Wear Parts: Wear pads, slide blocks, and heavy-duty guides in construction equipment and heavy machinery.
Food Processing: FDA-compliant star wheels, augers, rollers, and cutting boards.
Engineering Limitations & Alternatives
While Cast Nylon 6 is a wear-resistant plastic, specific environments may require different material properties:
Wet or Submerged Environments: Nylon absorbs moisture, which causes the material to swell and lose some tensile strength over time. Better Alternative: For submerged applications or tight tolerances in high humidity, choose Acetal (Delrin®).
Extreme Chemical Exposure: While resistant to alkalis, Nylon is highly vulnerable to strong acids. Better Alternative: For highly acidic environments, choose UHMW or PTFE (Teflon®).
High-Speed / Dry Running: Standard cast nylon can generate excess heat under high-velocity dry friction. Better Alternative: For high-speed dry bearings, use MD-Filled Nylon or an Oil-Filled Cast Nylon grade.
