The advantages of small plastic accessories
Small plastic accessories, with their unique material properties and manufacturing advantages, have a wide range of applications in fields that require precision, lightweight, and low cost. The following is a detailed breakdown of its main advantages and typical application scenarios:
The core advantages of small plastic accessories
Miniaturization and high precision
Micro injection molding technology can achieve complex structures of millimeter or even smaller sizes (such as micro gears and medical catheter joints), with tolerances controlled within ± 0.01mm.
High surface smoothness, suitable for optical components (such as lens holders) or precision instrument accessories.
Lightweight and portable
The weight is only 1/5~1/10 of metal accessories, suitable for weight sensitive scenarios such as wearable devices (such as smart watch buckles) and drone components.
Mass production cost and low
After one molding process, the cost of a single piece can be as low as a few cents (such as electronic device buckles, USB interface housings), making it suitable for large-scale production.
Functional integration design
Integrate multiple functions into a single accessory (such as buttons with sealing rings, conductive plastic contacts) through insert injection molding or two-color injection molding.
Fatigue resistance and wear resistance
Micro gears and hinges made of engineering plastics such as POM and PA66 can withstand high-frequency movements without deformation.
Insulation and Signal Stability
Used for high-frequency circuit board insulation gaskets and 5G antenna housings to avoid metal interference in signal transmission.
chemical compatibility
Resistant to reagent corrosion (such as PTFE used for laboratory micro valve cores), avoiding contamination of sensitive environments.
