Discover an Innovative Fastening Technique for the Automotive Industry

Their products, like the LiteWeight® pins, are tailored to meet the specific needs of automotive engineers, enhancing the efficiency of assembly processes and setting new industry standards in sustainability and performance.

Applications in Interior and Exterior Trim Components

In the field of interior and exterior trim, MultiMaterial-Welding® (MM‑Welding) can create high-strength joints directly on low-strength or non-metallic materials without additional inserts or pre-treatment processes.

• Bumpers, spoilers and various exterior trims: Joints are formed in a single process. No pre-embedded nuts or secondary assembly work is required, drastically cutting part counts and assembly steps.
• Wheel arch liners (plastic components): Achieves stable forming on thin-walled or flexible materials, eliminating cracking and deformation issues caused by conventional fastening methods.
• Carpets and floor mats (soft materials): Forms firm anchor points directly on fabrics or composite materials without extra metal fasteners or adhesive bonding.
• Headliners (with LiteWeight® pins): Combines lightweight fasteners to deliver an integrated solution featuring structural retention, weight reduction and high-speed assembly.
• Parcel shelves and other interior modules: Enables rapid modular assembly, lowering manual operation complexity and shortening production cycle times.

Applications in Structural and Functional Components

For load-bearing and safety-critical parts, MM‑Welding® delivers stable and reliable joint foundations within complex structures while streamlining manufacturing processes.

• Crash energy-absorbing structures (foamed inner door components): Creates direct joints within foams or composite constructions to avoid failure risks associated with traditional bonding or inserts.
• Luggage compartment functional parts: Offers fatigue-resistant connections that maintain consistent long-term performance under vibrating operating conditions.
• Trunk / cargo floor panels: Produces high-strength threaded connection points allowing repeated assembly and removing the need for extra reinforcement structures.
