With responsibility and foresight, EK is investing in precision plastics engineering – strengthening its future viability in a targeted and sustainable way. State-of-the-art injection molding technology, responsible material choices, and deep process expertise form the foundation for continued growth, innovation, and reliable partnerships.
Injection molding technology is a core area of expertise for EK and a key driver of innovation, quality, and sustainable growth. As a medium-sized company with more than 150 years of experience, we rely on state-of-the-art manufacturing processes, deep material knowledge, and collaborative partnerships. Our site in the Haan Technology Park is designed consistently for optimal material flow and equipped with high-quality production systems. To further reinforce this standard, we invested in two new injection molding machines from Arburg in 2025, including technologies for two-component injection molding. This investment will create additional capacity, increase our efficiency, and open new opportunities in product design.
These systems expand our portfolio both in the field of high-performance plastics and in sustainable material solutions. Even today, we process standard and high-performance polymers as well as biopolymers and recyclates such as ocean plastic. With clamping forces of up to 3,000 kN, component weights of up to 500 grams, and exceptional process stability, we manufacture precise components for a broad range of industries. Our customers benefit from series production, including assembly and finishing, as well as from our strong development expertise. We support projects from the initial idea through toolmaking and into full-scale production, always thinking along and ahead. Certified quality in accordance with IATF 16949 and ISO 14001 ensures compliance with the highest technical and environmental standards.
The application areas for our plastics engineering are diverse and wide-ranging, including automotive and e-mobility, electrical and control engineering, consumer goods, construction and fastening technology, and solar and environmental technology. This diversity enhances future resilience and drives innovative strength. Modern injection molding demonstrates its capabilities in many ways. Connection elements for insulating glass edge seals demonstrate how material-optimized variants and high dimensional accuracy support efficient assembly. Hairbrushes manufactured from recycled fishing nets illustrate how circular economy principles and high-quality product design can work together seamlessly. Hybrid components such as busbar modules combine precision-stamped parts with plastic overmolding to create compact and reliable high-current solutions for electromobility. All these solutions share a consistent foundation: precise manufacturing, deep material-performance understanding, and the ability to transform technical challenges into productive solutions.
With the new Arburg systems, we are decisively continuing our trajectory toward the future. The investment increases our capacity in two-component injection molding, raises automation levels, improves energy efficiency, and strengthens our competitiveness. It represents a clear commitment to our production site in Germany, to sustainable plastics engineering, and to long-term partnerships. “With this investment, we are not only enhancing our manufacturing depth and flexibility but also strengthening the innovative capability of our customers. For us, it is a visible demonstration that quality, efficiency, and sustainability are not contradictions – they reinforce one another,” explains Managing Director Frank Kronenberg. He continues: “Our customers value reliability, quality in every phase, and an open, constructive dialogue.
These principles make EK a strong partner today – and an even stronger one tomorrow. We evolve with our customers, think ahead, and deliver on time.”
