What are the advantages and disadvantages of plastic materials when making pins?

advantage
Low cost: the price of plastic raw materials is relatively low, the production and processing process is also relatively simple, can be large-scale injection molding and other processes, compared with metal materials, raw material procurement and production process can save a lot of costs, making plastic pins have a strong price competitiveness, suitable for mass production and daily use.
Light weight: The density of plastic is generally small, which makes the produced pin weight is very light, easy to carry and use, will not add too much burden to the other items, especially suitable for some occasions with weight requirements, such as light clothing, paper and other fixed.
Rich in color: In the production process, the plastic can easily add a variety of pigments or color masterbatches to achieve a rich variety of color effects, and even through special processes to produce a gradient color, pearl color and other unique colors to meet the personalized needs of different users for the color and appearance of the pin, increasing the decorative and interesting pin.

Good insulation performance: plastic is a good insulator, which makes plastic pins have unique advantages in the fixing or identification of some electrical equipment and electronic components, which can effectively avoid conductive risks and ensure the safety of use.
Good flexibility: some plastic materials have good flexibility, the pins produced are not easy to break, can withstand bending and stretching to a certain extent, adapt to different use scenarios and modes of operation, and can maintain better shape and performance even after repeated use.
shortcoming
Limited strength: Compared with metal materials, the strength and hardness of plastic is relatively low, and it is easy to deform or break when subjected to large external forces, such as when used to fix thicker and harder materials, it may not provide enough clamping force, or the opening and closing part of the pin is easy to damage after frequent use.
Poor heat resistance: The heat resistance of most plastics is poor, and it is easy to soften, deform or even melt in a high temperature environment, limiting the use of plastic pins in some high temperature occasions, such as not being used to fix items in a high temperature environment, otherwise it will affect the performance and service life of the pins.
Insufficient wear resistance: the plastic surface is relatively soft, and it is easy to produce scratches when rubbing with other objects, which affects the appearance and beauty of the pin, and may lead to serious surface wear of the pin after long-term use, reducing its decorative effect and performance.
General corrosion resistance: Although plastics have a certain tolerance to some common chemicals, in some organic solvents, strong acids and alkalis and other environments, plastic pins may be corroded, resulting in reduced performance, and are not suitable for use in chemically corrosive environments.
Environmental problems: some plastics are difficult to degrade, waste may cause pollution to the environment, with the improvement of environmental awareness, this has become an important problem faced by plastic pins in the use and treatment process, the need to take corresponding environmental protection measures for recycling.
