With the advent of automobile lightweighting, metal and plastic connections are widely in demand. How to quickly and effectively connect metals with plastics containing reinforced carbon fiber or glass fibers is an urgent problem to be solved.
In order to meet the requirements of the assembly line operation. The connection process must be fast, reliable and automated. Listed below are three of the most common methods for joining composite and metal parts in industry. Among them, laser-based joining technology is a relatively new technology. There are still many problems to be solved with this technology. These problems are not only related to efficiency, but also to connection strength and aging. This article will go into more detail about these issues.
Automotive workpieces such as metal and plastic connection methods include: mechanical connection, bonding, etcLaser connection
Mechanical connections. Fast and economical, stable process. The disadvantage is that the pores in the composite material destroy the fiber distribution and strength of the composite material. Connectors, such as screws, add weight to the component.
Bonding. There is a wide selection of adhesives for joining a wide range of materials. The disadvantage is that the surface needs to be pre-treated, the bonding process takes a long time, and the adhesive is required, which increases the cost.
Laser connectionFast and reliable, high connection strength, no excipients required. The disadvantage only applies to thermoplastics.
As a high-end and cost-effective application technology, plastic laser welding, which has the advantages of better strength, sealing, appearance, speed and stability than ultrasonic and hot plate welding in some auto parts manufacturing, is being popularized and applied at high speed in the field of automobile manufacturing.
The above is to share with you, the above is that plastics and metals can be laser welding applications, more plastic laser welding technology applications, so stay tuned.
