Double injection power tool housing
Short Description:
Double injection power tool housing is often used for power tools. It uses the advantages of different materials to achieve the comprehensive performance of good strength, vibration absorption, waterproof and dustproof, electrical insulation and comfortable holding
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.

2. What double-injection plastic parts are used on power tools?
Power tools are hand-operated tools driven by electricity. power tools need to work in different working conditions, withstanding high external forces and high voltage and current fluctuations. The parts required to construct them have good strength, insulation and comfortable and comfortable operation. Plastic materials just have such characteristics, so most of the power tools cover and handle are made of plastic materials by injection moulding.
The double-injection plastic parts are normally used in power tools' housing
1. Shell/Cover/Box: Contains fixed and protected internal components, withstands workload, prevents leakage of short circuit current and damages tools, and injures operators.
2. Handle: Used for hand holding operation. The main body is hard plastic, and the holding part is made of soft plastic.
3. Decoration components: Two different colors of decoration, easy to identify, translucent, make people feel beautiful and eye-catching.
The advantages of using plastics to make power tool parts
1. Plastics have low density, one eighth of steel, one ninth of copper and one third of aluminum. Making parts of power tools can greatly reduce the weight of tools.
2. Plastics are easily obtained by industrial manufacturing, and are cheaper than metals and wood. They can be recycled after being damaged. Wood is a non-renewable resource depending on natural growth and cannot be synthesized in large quantities by chemical production like plastics.
3. Power tools are generally made of high voltage power supply (110-220-380 volts), which has better electrical insulation than metal and wood plastic, and is safer and more reliable as the shell of power tools.
4. Plastics have better toughness and strength, and can better cushion and absorb tool vibration.
5. Compared with wood and metal, plastics can be easily obtained by moulding method to realize mass production, thus low cost.
6. There are many kinds of plastics and their performances are various. We can choose different plastics to get good performances. Waterproof, shock absorption, heat resistance, wear resistance, durability
Material selection for plastic Parts of power tools
1. Nylon plastics are generally used as the matrix material (or ABS material) for the electric domestic tool housing.
Nylon material has good strength and toughness, as well as electrical insulation. In order to obtain more accurate part size, glass fibers are usually added to nylon.
For example, PA6 + GF10%, PA6 + GF20% and so on.
2. TPU soft glue is used for hand-held parts to get good handle.
3. Common plastics such as ABS can be used to make unbearable parts.
Double-injection molding in the same injection molding machine, to complete injection molding parts in one injection cycle, it avoids taking out parts halfway. The combination of the two materials is firmly and the quality and production efficiency are higher than that of normal plastic over-molding, which ensures the reliability and durability of electric tools. Our company has different tonnage of two-color injection molding machines and many years of two-color injection production experience. We are dedicated to provide you with the mold making and injection molding services for the two-color plastic parts of electric tools. Please contact us.
