Lightweight automobiles have become an important direction for the development of the automobile industry, which not only improves the driving performance of automobiles, but also enhances automobile safety, saves fuel costs, manufacturing costs, and further meets market demand. When designing and producing automobiles, various manufacturers have achieved the goal of lightweighting of automobiles by widely applying lightweight plastic products. It can be said that in addition to the use of high-strength materials for the body, many parts will be made of plastic as much as possible. According to experiments, the mass of the car is reduced by half, and the fuel consumption is also reduced by nearly half.


Interior and exterior trim is an important part of vehicle lightweight


The front and rear bumpers of a car are a typical representative. In the early years, the bumpers of the car body were all made of metal, and some were stamped with steel plates and then welded with the body. However, due to factors such as the lightweight, mass production and aesthetics of the car, car manufacturers finally found A better alternative - plastic bumpers. Plastic bumpers can not only save manufacturing costs, but also have lower industrial-level requirements and are easier to produce. Therefore, after the manufacturing cost is controlled, it will eventually be reflected in the price of the car.


The lightweight of interior and exterior accessories of automobiles is an important part of the lightweight of the whole vehicle. With the continuous in-depth research and development of plastic technology, many auto parts have reached the demand for plasticization, including instrument panels, door inner panels, and body coverings. parts, chassis, bumpers, fuel tanks, engine intake manifolds and clutch actuation systems, etc.


Laser-cut plastic nozzles to accelerate the pace of lightweighting


In order to meet mass production, most of these plastic parts are processed by injection molding. Injection molding will inevitably produce nozzles. The nozzle refers to the part of the runner produced after injection molding, which is the excess leftover material other than the product, such as the intersection of the mold and the opening of the injection material left during the production of the plastic product. These excess scraps need to be cut prior to assembly.


Today, in the cutting of plastic nozzles, laser cutting has become the main equipment. As we all know, laser cutting machines have excellent precision and accuracy. Due to the different shapes and sizes of these plastic nozzles, the requirements for cutting are higher, but if it is done by hand, it cannot guarantee the accuracy of cutting, and the efficiency is not high and the speed is slow. Therefore, laser equipment solves this problem very well.
