Double-injection housings are often used on power tools.

Electric tools generally bear strong electric or mechanical vibration, or work in high and low temperature, high humidity and dusty environment. According to the requirements of different parts of the product, double-injection molding can combine different characteristics of plastics into a complete part, and get good comprehensive mechanical and electrical performance, human-machine operation or water-proof sealing. Therefore, the double-injection housings molding is widely used in the parts manufacturing of electric tools.

1.What is poer tools

A power tool is a tool that is actuated by an additional power source and mechanism other than the solely manual labor used with hand tools.

The most common types of power tools use electric motors. Internal combustion engines and compressed air are also commonly used. Other power sources include steam engines, direct burning of fuels and propellants, or even natural power sources like wind or moving water. Tools directly driven by animal power are not generally considered power tools.

Power tools are used in industry, in construction, in the garden, for housework tasks such as cooking,  cleaning, and around the house for purposes of driving, drilling, cutting, shaping, sanding, grinding, routing, polishing, painting, heating and more.

Power tools are classified as either stationary or portable, where portable means hand-held. Portable power tools have obvious advantages in mobility.

Stationary power tools however often have advantages in speed and accuracy, and some stationary power tools can produce objects that cannot be made in any other way.

Stationary power tools for metalworking are usually called machine tools. The term machine tool is not usually applied to stationary power tools for woodworking, although such usage is occasionally heard, and in some cases, such as drill presses and bench grinders, exactly the same tool is used for both woodworking and metalworking.
