What hi-con does

hi-con GmbH & Co. KG is a German specialty plastics manufacturer founded in 1995 (incorporated 1996), operating from its headquarters in Groß-Umstadt and a production facility in Langen (Hessen). The company provides vertically integrated injection molding services spanning part development (Teileentwicklung), precision tool construction (Werkzeugbau), prototyping and small-series runs (Kleinserien & Prototypen, delivered in 1-4 weeks), and series production on an eight-machine park with clamping forces from 250 kN to 1,500 kN and shot weights of 0.01-0.3 kg. Two of those machines operate under cleanroom conditions for medical, optical, and electronics applications. Its technical capabilities cover standard thermoplastics (ABS, PA, POM, PP), high-temperature materials (PEEK up to 30% glass fiber, PEI, LCP, PAI, PESU), multi-component (2K) parts, and a proprietary biodegradable material line marketed under the GreenPlastics sub-brand with up to 95% biodegradation. Engineering work is supported by SolidWorks Plastics and VisiCad for mold-flow and tolerance simulation.

The company serves B2B enterprise customers in medical technology, optics, electronics, automotive and commercial vehicles, security technology, machinery, and energy/utilities, with documented applications including dental X-ray connectors, binocular objectives, IR viewing windows, EV service plugs, and dental suction cannulas. Its go-to-market is a direct enterprise development-partnership model: customers engage hi-con early in product design, the company identifies cost drivers and material/geometry optimizations, and pricing is quote-based against customer specifications. Revenue is generated through custom part production, tool development fees, engineering services, and material sales. The firm is privately held under a GmbH & Co. KG structure with hi-holding GmbH as general partner and Franz G. Hiemstra as authorized managing director; there is no disclosed external institutional or venture capital backing.

Operationally the company is small (1-10 employees by headcount band) and concentrates on the DACH market with no disclosed international expansion. It holds ISO 9001:2015 certification (certificate Z231227) and reports a documented case-study outcome of 33% material reduction and 60% production time reduction while producing 240% more parts at equivalent quality. Recent strategic activity has centered on brand refresh (August 2025), formalization of the GreenPlastics sub-brand, addition of assembly and kitting services, and the dedicated cleanroom build-out — collectively positioning the company as a development partner for technically demanding niche applications rather than a high-volume commodity molder.

Core offering

hi-con is a full-service injection molding solutions provider that designs, tools, prototypes, and produces custom plastic parts—standard, high-temperature (PEEK, PEI, LCP, PAI, PESU), complex/delicates, and precision components—using an 8-machine park (250–1,500 kN) including two cleanroom-capable machines. The company delivers a vertically integrated value chain from part development and mold construction through small series and large-scale production, with GreenPlastics biodegradable materials and assembly/kitting as additional offerings.

Product overview

hi-con is a full-service injection molding solutions provider offering a unified portfolio of design, prototyping, tooling, and production services for plastic parts. The core offering centers on Standardteile (standard parts), Hochtemperatur-Teile (high-temperature parts), Komplexe & filigrane Teile (complex/delicates), and Präzisionsteile (precision parts), all delivered through a vertically integrated workflow: Teileentwicklung (part development) → Werkzeugbau (tool construction) → Kleinserien & Prototypen (prototyping/small series) → Produktion (full-scale injection molding). GreenPlastics serves as a dedicated sub-brand for biodegradable materials, while Reinraum-Produktion (cleanroom) and Teilemontage & Konfektionierung (assembly) extend the value chain to turnkey, ready-to-install solutions.
