Laser Welding Solutions for Automotive Rear Bumper Energy Absorption Blocks

Date：2026-04-16 14:06 Source：daokedao Browse：26

Automotive rear bumper energy absorption blocks absorb impact energy during rear collisions, requiring high toughness, impact resistance, and lightweight design, adapting to vehicle collision safety standards. Traditional welding methods add weight and have poor impact absorption performance, while adhesive bonding cannot withstand high impact forces. DaokeDao plastic laser welding provides a high-strength, lightweight joining solution for PP and EPP energy absorption blocks, forming a continuous weld with tensile strength ≥25MPa, capable of withstanding impact forces up to 4000N. The non-contact process avoids mechanical damage to the block structure, maintaining its impact absorption performance and structural integrity. The welding process is efficient, with no need for post-processing, reducing production costs and improving assembly efficiency. The equipment supports complex block designs, automated production, cycle time 10-13 seconds per unit, complying with automotive safety standards (ISO 26262), helping automakers improve rear collision safety and reduce vehicle weight.
