Welding, roller hemming, flanging, bonding – a problem? Not for us! With comprehensive expertise, our team masters all processes in car body construction - from tried-and-tested to ultra-modern technologies.

Through the precise integration of joining techniques and thermal processes, we deliver top-quality, precision-fit body parts. You can rely on our solutions - today and tomorrow.

We join what belongs together

LAEPPLE Automotive production

We manufacture assembly components for the automotive industry in all sizes and degrees of complexity on our automated body-in-white systems, equipped with robots.

We offer scalable manufacturing solutions and cover a wide range of parts - from simple reinforcement elements to complex assemblies for small and large series.

We process a wide range of materials: steel and aluminum, high-performance plastics, hydroformed hydroformed parts, extruded profiles, carbon (CFRP), magnesium as well as hot-formed and die-cast parts are used as required.

State-of-the-art joining techniques such as laser and resistance welding or bonding processes ensure maximum strength and durability.

Thanks to cycle time-optimized processes, agile structures and sustainable process optimization, we manufacture precisely and resource-efficiently with our strong team.

Joining processes knowledge

LÄPPLE Automotive has an expertise in all major joining technologies, backed by deep, long-established know-how within our organization. While our U.S. facility currently focuses on specific processes tailored to local production needs, our broader expertise enables us to offer additional joining methods whenever projects demand it. This flexibility ensures that customers benefit not only from proven capabilities but also from a partner ready to expand and adapt with precision and confidence.

Our parts portfolio

Hang-On-Parts

Hang-On-Parts

Hang-on parts are removable outer skin parts that are “attached” to the body structure in their fully assembled state – these include doors, rear and front flaps, and fenders. Thanks to our manufacturing expertise, we guarantee consistently tight tolerances and flawless surfaces – optionally including surface finishing and painting.

Chassis assemblies

Chassis assemblies

The chassis assembly refers to all load-bearing elements of the vehicle chassis — from the vehicle platform to the front and rear sections to the main floor — which are firmly bolted or welded to the body structure and serve as a stable base for the entire upper structure. Using high-precision joining processes and digital process monitoring, our team ensures that the parts meet the highest standards of rigidity and quality.

Structural components

Structural components

Structural components are load-bearing body parts such as A-, B- and C-pillars, crossmembers, front wall, inner side panel, as well as roof and cowl frames. They ensure rigidity and occupant protection. Our team combines many years of experience and material expertise with state-of-the-art manufacturing and testing technologies. In this way, we ensure that every structural component delivers maximum crash performance and meets the highest safety standards.

Parts for e-mobility

Parts for e-mobility

Our expertise includes the production of components for vehicles with alternative drive systems. Manufacturing is specifically designed for multi-material mixes and high safety requirements. Examples of our products in this area include battery covers, upper housings for battery modules, and modules for high-voltage battery packs, including integrated corrosion and fire protection for reliable performance and durability.
