The use of plastic toolboxes for electric tool accessories is mainly based on the following reasons:
1. Lightweight and portable: Compared with metal toolboxes, plastic materials have lower density and significantly reduce weight. Workers carry plastic toolboxes with power tool accessories to shuttle between different work sites, such as different floors of construction sites or different rooms of decorated houses, without causing excessive physical exertion due to the heavy toolboxes. The easy and portable characteristics improve work flexibility and efficiency.
2. Cost effectiveness: The cost of plastic materials is usually lower than that of metals, and large-scale production of plastic toolboxes can effectively reduce production costs. For power tool manufacturers, reducing supporting costs allows for more resources to be invested in research and marketing, and also enables consumers to purchase power tool sets including toolboxes at more affordable prices, enhancing product market competitiveness.
3. Corrosion resistance: Electric tool accessories are mostly made of metal materials, and the working environment often contains corrosive factors such as water vapor, dust, and oil stains, especially in outdoor damp construction sites and auto repair workshops. Plastic toolboxes have good corrosion resistance and will not rust or corrode like metal boxes. They can protect the accessories inside the box from external corrosion for a long time and extend the service life of the accessories.
4. Insulation performance: Electric tool operation involves the use of electricity, and once leakage occurs, the consequences are serious. Plastic is an insulator, and even if the toolbox accidentally comes into contact with electric tools or wires that leak electricity, it can block the conduction of current, providing additional safety protection for users and reducing the risk of electric shock.
5. Design diversity: Plastic is easy to shape and can create toolboxes in various shapes, sizes, and colors. Manufacturers can customize toolboxes that meet their specific needs based on the quantity and size of accessories in different power tool sets. They can also distinguish tool sets of different series and purposes through color, making it easy for users to quickly identify and access them.
6. Buffer and shock absorption: During handling and transportation, bumps and collisions are inevitable. Plastic material itself has a certain degree of elasticity. Compared to rigid metal, it can absorb and buffer some impact forces, reduce the probability of damage and deformation of electric tool accessories in the box due to vibration and collision, and better protect precision accessories.
