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 OnceSince 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 TapeExtend 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 HookThe 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).
Interstate Plastics provides high-performance Machine Grade polycarbonate for applications requiring heavy-duty durability and tight tolerances. Unlike standard glazing sheet, Machine Grade polycarbonate is an engineering thermoplastic designed with low internal stress. While this stress-relieving process results in a slight haze or frosted appearance, it ensures the material remains dimensionally stable during intense machining and fabrication. It offers the same legendary impact resistance as standard polycarbonate but in thicker gauges suitable for structural components. Looking for online cut-to-size options, thinner gauges, or standard window glazing? Cut-to-size is available for certain Machine Grade thicknesses. This material is the preferred choice for engineers and machinists. While it trades optical transparency for mechanical reliability, it is specifically manufactured to hold its shape during complex fabrication. It is the correct choice if you need: When machining parts, the difference is critical: Read Polycarbonate vs. Acrylic Guide â?º Machine Grade polycarbonate is "tool-friendly." Its ductility allows for aggressive machining speeds and feeds. It creates long, continuous chips rather than dust, and allows for cold-bending in thinner gauges without structural failure.
