About Kroma International
Kroma International GmbH, based in Lahr/Schwarzwald, develops, produces and optimises injection moulding tools, technical plastic parts, assemblies and system solutions. For more than 20 years, the company has specialised in complex tooling and injection moulding technologies and has delivered over 1,000 tools and moulds as well as more than 800 injection moulding projects. The value chain ranges from design and simulation (CAD, Moldflow, FEM) to in-house toolmaking of up to 8,000 kg tool weight, complemented by global sourcing of tools up to 10 tonnes via partner companies in China. The company's own injection moulding production comprises 44 machines with clamping forces of 35 to 1,700 tonnes for 1K and 2K parts made of technical plastics including high-performance materials such as PPS, PPSU and PEEK. As a system supplier, Kroma also handles assembly, packaging and logistics with 4,000 m² of warehouse space and direct access to the A5 motorway. Industries include industrial, automotive, medical technology and specialty plastics.
