Plasma treatment of car dashboard before coating

Recently, BYD Haise 05DM-i and the second-generation Song Pro DM-i were officially launched on the market, with a price range of only 112,800-142,800 yuan.

The "price war" in the automotive industry is becoming increasingly fierce, and car companies such as BYD, Tesla, and BMW are grabbing market share 

by cutting prices.

The automobile price war has also prompted automakers to adopt cost control strategies in the field of automotive interior and exterior decoration, 

by optimizing production processes or adopting advanced technologies to improve production efficiency and product quality and reduce production costs.

Plasma Applications on Car Dashboards

Automotive interior parts are usually made of plastic materials such as polypropylene (PP), which have weak surface dispersion and poor bonding properties. 

This makes it difficult for covering materials (such as leather) to adhere firmly to the interior parts without treatment, and it is easy to debond and crack under the sun.

In particular, the surface treatment of the automotive dashboard is more difficult because it contains multiple curved surfaces, protrusions and grooves and other complex structures.

The traditional treatment method is to use flame method to increase the surface energy, but because of its low production capacity and high flame temperature, 

it is easy to cause problems such as material surface shape, so automobile manufacturers prefer surface treatment methods that are efficient and less likely to cause material damage.

Plasma technology not only improves surface energy, but also conforms to the trend of environmental protection and efficient production. It is introduced into production by more and more automobile manufacturers as an important surface treatment technology.

Large chamber vacuum plasma cleaning machine

SINDIN large-cavity vacuum plasma cleaning machine can process large-sized curved, concave and convex non-planar materials. It can be used for pre-treatment of automobile instrument panel coating and can achieve efficient, all-round and uniform surface activation treatment.

Before covering the car dashboard, surface treatment by SINDIN vacuum plasma can effectively enhance the surface activity of materials such as PP, making it easier to combine with the covering material, thereby improving the firmness and durability of the covering.

Comparison between plasma treatment and flame treatment

Although the traditional flame method is widely used, it has the disadvantages of complex operation, long processing time, low production capacity and low precision, which makes it difficult to meet the needs of the modern automobile manufacturing industry. Plasma treatment is favored by major automobile manufacturers due to its advantages such as environmental protection, high efficiency, uniform treatment effect and ability to process complex shapes. Especially in terms of capacity improvement, plasma surface treatment has more advantages.

The flame method can only process 1pcs at a time, while the plasma method can process at least 8pcs at a time, which can greatly improve production efficiency and increase production capacity, thereby shortening the production cycle and meeting the needs of efficient production.

After testing and comparison, the production capacity of SINDIN vacuum plasma cleaning machine is 1 times that of flame method.

According to the customer's acceptance criteria, the plasma-treated car dashboard did not show any debonding or warping after wrapping. At the same time, the pull-out force test also met the industry standards.
