About sinit
sinit kunststoffwerke gmbh & co. kg is a plastic-processing system partner headquartered in Rödental near Coburg. The company supports projects throughout the entire life cycle: from design and material consulting through prototyping and in-house toolmaking to series production in plastic injection moulding using 1K, 2K and multi-component technology. Components, assemblies and module solutions are manufactured from thermoplastics, glass-fibre-reinforced plastics with high flame retardance and high-performance polymers; plastic and metal components are joined into sub-assemblies. Assembly ranges from manual small-series assembly to fully automated lines for large series, supplemented by packaging up to customer-specific end packaging. Customers come from aerospace, automotive, household and consumer goods, mechanical engineering and electrical engineering. With 285 employees, four production sites in Germany, the Czech Republic and Romania, 4500 tonnes of raw material and around 145 million delivered components per year (€58 million revenue in 2024), sinit is equipped for small batches as well as large orders.

Materials and Processes
Thermoplastics
Standard material for interior and technical parts of the automotive industry in 1K and 2K technology.
Glass-fibre-reinforced plastics with high flame retardance
Used in electrical engineering, e.g. for fuse housings, busbar systems, carrier rails and distribution enclosures.
High-performance polymers
Temperature-, chemical- and mechanically resistant polymers for lightweight components in aerospace.
Heat-resistant, impact-resistant injection moulding materials
For durable, easily hygienic household and consumer goods products.
Metal components
Joined with plastic parts in sub-assemblies to form complete units.
