General material of plastic shell
1) ABS
ABS is currently the most widely used polymer, which is easy to form, relatively low in price, and low in temperature resistance. It is generally used in household appliances.
2) PC
The advantages of PC are high transparency, high impact strength, high temperature resistance, high dimensional accuracy, and flame retardancy. It has ultra-high strength and elasticity coefficient, and can be used in a wide temperature range. Due to its high transparency and strong dyeing ability, it is suitable for making various colors for the power supply casing. At the same time, environmentally friendly materials that comply with health and safety are mainly used in industries such as home appliance lighting and plastic shells.
3) PC+ABS synthesis
It is a material synthesized using ABS and PC, which has the characteristics of both pre PC and ABS. It has excellent molding performance, good flowability, and relatively high strength. It can also be used for secondary processing properties such as metal spraying, electroplating, welding, bonding, etc. It is currently widely used in industries such as electrical components, household appliances, computers, instruments, and meters.
Advantages of Plastic Housing
1. Lightweight
Plastic is a lighter material with a relative density between 0.90 and 2.2. This characteristic allows plastics to be used in the production of products that require weight reduction.
2. Excellent chemical stability
The vast majority of plastics have good corrosion resistance to chemicals such as acids and alkalis. The special chemical stability even surpasses gold, making it an ideal corrosion-resistant material.
3. Excellent electrical insulation performance
Plastic is a poor conductor of electricity, with high surface and volume resistance. Plastic has a wide range of applications in the electronic and mechanical industries.
4. Poor conductors with heat insulation and shock absorption effects
The thermal conductivity of plastic is relatively low, and its insulation, sound insulation, and shock resistance are better.
5. Wide distribution of mechanical strength and high specific strength
Some plastics are as hard as stone or steel, while others are as soft as paper or leather; From the perspective of mechanical properties such as hardness, tensile strength, elongation, and impact strength of plastics, there is a wide range of distribution and a wide range of options for use. Due to its small specific gravity and high strength, plastic has a high specific strength.
6. Easy to process
The plastic shell only requires one-time injection molding, without the need for secondary processing. The molding is simple and can reduce unnecessary resource waste in terms of time and processing. Compared to the complex process of metal shells, it has greater advantages.
7. Convenient to carry
Plastic shells are usually made of plastic material called polycarbonate, which is very lightweight and easy to carry around without feeling burdened. It reduces the weight of the product itself and is also easy to carry and transport.
8. More secure
Compared to conductive metals, plastic itself is insulated, which greatly improves the safety of the product itself.
9. Long service life
The durability of the plastic shell itself is very good, and damage is rare.
10. More environmentally friendly
The plastic shell has passed multiple environmental certifications, and all leftover materials and waste templates can be recycled and reused, with zero waste discharge.
11. Beautiful appearance
In terms of appearance, plastic shells have more options than metal shells. The appearance and color of the logo can be modified according to customer needs.
12. Relatively cheap price
Compared to other materials, plastic shells are more economical, can greatly save processing and production costs, and have guaranteed quality.
