Manufacturing Technologies and Processes for Automotive & Railway Seats

At Clerprem, we believe that technological innovation is the key to delivering outstanding, highly engineered products recognized worldwide. That’s why we continually invest in cutting-edge manufacturing technologies, fully integrated into our production sites, to ensure precision, reliability, and top-tier quality throughout every phase of the process.

As a fully integrated OEM seat manufacturer, Clerprem controls every production technology in-house — from aluminium die casting and robotized welding to CNC milling, polyurethane foaming and upholstery — to deliver lightweight, certified automotive and railway seats (EN 15085, EN 45545-2, IATF 16949).

Engineering, Automation, and In-House Expertise

Thanks to our fully integrated structure, we can manage every project internally — from the initial concept to full-scale production. Our state-of-the-art equipment enables us to handle even the most complex manufacturing challenges efficiently, optimizing both lead times and costs while ensuring consistently high quality.

Our core technologies include:

  • ✅ Automated stations for flexible polyurethane foam molding, ideal for high-quality automotive and railway seats

  • ✅ High-precision CNC cutting and milling centers for complex multi-material processing

  • ✅ Advanced metal bending machines, combining versatility and performance

  • ✅ FDS robots (Flow Drill Screwing) for automated fastening of metal components

  • ✅ Automated MIG, MAG, and TIG welding stations for secure and durable assemblies

  • ✅ A wide range of CNC milling machines for complex 3D shaping and finishing

These technologies ensure high repeatability, production efficiency, and certified quality — even for large-scale volumes.

Italian Design Meets Technological Innovation

One of Clerprem’s defining strengths lies in its ability to merge Italian design, functionality, and technology. Style, ergonomics, and attention to detail are embedded in our processes: each product is designed to be aesthetically refined, high-performing, and tailor-made for the customer.

In an increasingly competitive and global market, our value lies in being a trusted technological and manufacturing partner, offering innovative, reliable, and industrial-scale solutions.
