Why the Automotive Industry Uses Vacuum Forming
At present, the competition in the automotive industry is fierce, and the requirements and development time for automotive parts are becoming more and more stringent. Using vacuum forming technology to manufacture automotive parts can bring excellent cost-effectiveness and reliability to automobile manufacturing. First of all, vacuum forming technology can process a variety of thermoplastics, such as ABS, ASA, PP, PE, etc. Different materials have different uses in the manufacturing of the automotive industry. For example, PE material is very suitable for making fenders, ABS can be used to make automotive interior parts such as dashboards, interior panels, etc., ABS+ASA laminated materials can also be used to make car shells, and PMMA can be used to make car lampshades, etc. Secondly, products such as car bumpers and tail wings are usually relatively large. Using vacuum forming and bonding technology can greatly reduce the cost of product manufacturing. Furthermore, vacuum forming technology uses plastic, which has a great advantage in weight compared to metal parts. Without affecting the overall performance of the car, it can bring a certain improvement to the endurance of fuel vehicles and new energy vehicles. Finally, vacuum forming technology can adapt well to the shape of automotive parts. Whether it is a car seat shell with complex lines or a car shell with streamlined appearance, side skirts and other parts, vacuum forming technology can achieve a perfect appearance.

Applications of Vacuum Formed Plastic Components in Automotive
This is a patrol/sightseeing car roof, the dimension can reach 3*1m. Now the image products have been vacuum formed, CNC cutting, de-burring, and it’s polishing before painting. The product has a total of five colors, red, blue, black, purple, and white, all in white as the original color. Each product in addition to its own UV-resistance particles added when making the raw materials, spray paint also has a strong UV-resistance function, which can effectively increase the service life of the product outdoors, and provide a better shading effect.
The blue camouflage and the white car shell part in the image are car shell protectors, produced by vacuum forming. In recent years, more and more people are interested in off-road mountaineering. The original intention of this shell is to prevent the damage caused by the scratches of branches and stones on the shell of the car. And at the same time, the vacuum forming car shell also has the ability to resist impact, to a certain extent can protect the life safety of the driver and passengers. And after several improvements, now the installation is getting easier and easier.
This is a rear wing from one of Nissan’s cars, also known as spoiler, which is made by assembling and gluing after vacuum forming. Up to now, there are a lot of car modification parts that use vacuum forming to make it. Compared with injection molding, the mold in vacuum forming can be much cheaper, and also requires less time to make. When the quantity of products required is small, especially for large automotive parts such as dashboards, housings, bumpers, spoilers, and so on, the vacuum forming process is the most suitable.
Some Suggestion About Automotive Products
For automotive parts, usually should pay attention to the following four places: first of all, all sprayed paint will choose PU paint, which is a kind of paint with a strong anti-UV function. The second is that the automotive parts are usually more precise, and the jig must be made in all the places where the thickness and the hole position are measured. Third, automotive parts have high requirements for appearance, which means that the requirements for painting are very high and the requirements for mold surface are usually higher than other products. Finally, automotive products need impact resistance, we will add impact-resistant raw material particles in the production of raw materials.
