Polycarbonate Thermoplastic Machining
Polycarbonate polymers, or PCs, exhibit excellent toughness, high impact strength, and a high modulus of elasticity. Most types of polycarbonate thermoplastic offer transparency and high optical clarity. This material is relatively easy to work with, and Upland Fab are experts in machining complex, high precision parts from polycarbonate polymers.
Benefits of Working with Polycarbonate Polymers
Polycarbonate thermoplastic provides high heat deflection, very low moisture absorption, favorable low frequency and high voltage insulating characteristics, making it an ideal material for electrical and electronic components. PCs also provide high tensile, shear, and flexural strength, and retain these characteristics at elevated temperatures. Excellent creep resistance and flow resistance, a low coefficient of thermal expansion, and low deformation characteristics under load further improve the materials’ performance in high temp applications.
Polycarbonate polymers are highly versatile materials that are useful for a broad range of applications. Common uses for PCs include equipment housings, electrical connectors, insulators, and fittings, relay components, medical devices, and many more.
Sheet grade polycarbonate is also called Lexan or Makrolon whereas acrylic sheet polycarbonate is commonly referred to as Lucite. Both Lexan and Lucite have benefits and drawbacks. Both are two of the most frequently used see-through plastics but Acrylic will have a shinier surface but is easier to crack. Where polycarbonate is stronger and more impact resistant it's also easier to scratch.
There are many grades of polycarbonate thermoplastic available, from general purpose to machine grade to glass-filled and more. Each PC grade offers unique characteristics that may make it better suited to your application than others. Contact us to discuss your material requirements.
High Precision Machining of Polycarbonate Thermoplastic Parts
When working with polycarbonate polymers, Upland Fab utilizes multi-axis machining to ensure that tight tolerances are maintained from the first part to the last. Our CNC machining capabilities enable us to produce consistently high precision parts, with minimal handling and fixturing requirements. In many cases, even the most complex parts can be completed in a single operation for fast turnarounds.
Thanks to our DPD/MBD processes (Digital Product Definition/Model-Based Definition), we can work directly from your completed CAD models. Working straight from your digital design files eliminates manufacturing errors and ensures that your parts match your exact requirements. We can deliver cost-effective polycarbonate thermoplastic parts that are 100% on spec.
