Automobile lightweight has become an important direction of the development of the automobile industry. It not only improves the driving performance of the automobile, but also enhances the safety of the automobile, saves fuel costs, production and manufacturing costs, and further meets the market demand. When designing and producing automobiles, manufacturers have achieved the goal of automobile lightweight by widely using lightweight plastic products. It can be said that in addition to the high-strength materials used for the body, many parts will be made of plastic as much as possible. According to the experiment, if the quality of the car is reduced by half, the fuel consumption will also be reduced by nearly half.
Interior and exterior decoration is an important part of vehicle lightweight
Front and rear bumpers are typical. In the early years, the bumpers of car bodies were all made of metal. Some of them were stamped with steel plates and then welded with the car body. However, due to factors such as lightweight, batch production and aesthetics, automobile manufacturers finally found a better alternative - plastic bumpers. Plastic bumper can not only save manufacturing cost, but also has lower requirements for industrial level and is relatively easy to produce. Therefore, after the manufacturing cost is controlled, it will eventually be reflected in the price of the car.
The lightweight of automobile interior and exterior accessories is an important part of the lightweight of the whole vehicle. With the continuous in-depth research and development of plastic technology, many automobile parts have reached the demand for plastics, including instrument panel, door inner panel, body covering, chassis, bumper, fuel tank, engine intake manifold and clutch actuating system.
Laser cutting plastic nozzle, speeding up the pace of lightweight
In order to meet the mass production, most of these plastic parts are made by injection molding. Injection molding will inevitably produce nozzle. The nozzle refers to the runner part generated after injection molding, which is the leftover materials other than products, such as the mold intersection and injection opening left by plastic products during production. These surplus leftovers need to be cut before assembly.
Nowadays, laser cutting machine has become the main equipment in the cutting of plastic nozzle. As we all know, laser cutting machine has very superior precision and accuracy. Due to the different shapes and sizes of these plastic nozzles, the requirements for cutting are high. However, manual cutting can not guarantee the accuracy of cutting, and the efficiency is not high and the speed is slow. Therefore, the laser equipment has solved this problem well.
