PC exhibits resistance to various chemicals, which makes it suitable for applications in chemically challenging environments. Not all plastics offer the same level of chemical resistance.

Polycarbonate is used for automotive components such as headlamp lenses, interior trim, and window glazing due to its impact resistance and lightweight properties.

Polycarbonate, often referred to as PC, is a thermoplastic polymer known for its exceptional characteristics. It has gained widespread recognition in various industries due to its impressive combination of physical and chemical properties.

Compared with other plastic injection molding, the polycarbonate injection molding process requires special attention. Our previous blog Principle of Injection Molding Process explains the injection molding process in detail.

Polycarbonate can be sensitive to moisture and high temperatures, potentially leading to hydrolysis and material degradation. Prevent hydrolysis and degradation by thoroughly drying the material, maintaining temperature control, and considering additives or stabilizers to enhance resistance.

Optical grade Polycarbonate molded parts are optically clear and have near-total light transmittance and a very low haze factor. UV additives often adapt to PC to protect against direct, long-term exposure to sunlight. By adding flame retardant, polycarbonate can meet the UL 94 standard.

Aim for a minimum wall thickness of 0.040 inches (1 mm) and a maximum of 0.150 inches (3.8 mm) for PC parts. This range supports thin walls and complex geometries.

Polycarbonate injection molding is a manufacturing process used to create various plastic parts and components from Polycarbonate resin. The process typically includes steps such as material preparation, mold design, machine setup, injection of the molten Polycarbonate, cooling, ejection, quality control, and the repetition of these steps for mass production. Proper control of temperature settings, injection parameters, cooling, and cycle times is essential to achieve consistent and reliable results in PC injection molding.

Polycarbonate comes in several types or grades. Common grade polycarbonates include Medical-Grade Polycarbonate, Food-Grade Polycarbonate, and Generic-Grade polycarbonate.

When using ribs for additional strength or support, make the rib thickness between 0.5 and 0.6 times the thickness of the adjoining wall. Avoid using rib heights more than three times the thickness.

Polycarbonate supports a variety of surface finishes, including gloss and high-gloss finishes. Matte finishes can reduce glare, making them suitable for control panel overlays. Non-glossy finishes may be preferred for certain applications like screw caps.

The injection mold structure and design directly influence various aspects of the final product, including its dimensional accuracy, surface finish,

Polycarbonate is employed in medical equipment and devices, including IV connectors, housings, and surgical instruments.

Injection molding flow marks are a common injection molding defect. While flow marks generally do not influence the structural integrity

Here are the typical ranges for some key PC injection molding process parameters for reference. The specifications parameter number needs to be adjusted depending on PC types and grades.

PC serves as an excellent electrical insulator, making it suitable for electrical and electronic components. Some other plastics may not provide the same level of electrical insulation.

Polycarbonate can experience significant shrinkage as it cools after injection. This can lead to dimensional inaccuracies in the final part. To mitigate shrinkage, adjust mold design for compensation, lower melt temperature to reduce cooling rate, and apply proper packing and holding pressure during molding.

When designing PC injection molding parts, these guidelines help ensure that PC parts meet end-use requirements and maintain high quality.
