Sk Industriemodell Gmbh

What Sk Industriemodell Gmbh does

SK Industriemodell GmbH is a privately held German contract manufacturer founded in 1983 and headquartered in Übach-Palenberg (City Region Aachen, North Rhine-Westphalia). The company specializes in plastic injection-molded prototype parts and small-volume series, operating as a single integrated site that performs every process step in-house — from engineering and CAD design, through mold fabrication (including 3D-printed molds via the proprietary Print&Inject process), injection molding, and finishing. Its core differentiator is the Print&Inject technology, co-developed with RWTH Aachen's PEM group, which uses 3D-printed injection molds (including FIM/lye-dissolvable variants) to combine the speed and flexibility of additive manufacturing with the material diversity of injection molding, enabling functional prototypes from series-grade and medically certified plastics.

The company serves a diversified set of verticals — Mobility/Automotive (including EV customers such as e.GO Mobile AG), Medical Technology, Machinery and Plant Engineering, Construction, and adjacent industries (furniture, biotech, IT/electronics, garden/leisure). Named customers include AGC Glass Europe, Safet Medex (20+ year relationship), fka Aachen, A B Graphic International, and e.GO Mobile AG. SK Industriemodell has actively participated in publicly funded research collaborations with RWTH Aachen, Fraunhofer IPT, the University of Cologne and FH Aachen (e.g., Additive Herstellung von Spritzgusswerkzeugen, BioStrukt, EnAbLe KMU, Zellkraftmessung, MC-LaserBip) and holds ISO 9001:2015 certification.

The business model is project-based and quote-driven: customers contact the company by phone or email, SK Industriemodell engineers contribute design-for-manufacturing input from the earliest design phase, and parts plus tooling are billed ex-works in EUR with separate mold costs (typically retained by the company for at least two years). Distribution is entirely direct, with no resellers or third-party channels; the company is owned and managed by Dipl.-Ing. Sebastian Krell, who completed a management-buyout succession from founder Werner Schanz on 1 July 2015. Pricing is not publicly disclosed and varies per project.

Core offering

SK Industriemodell GmbH is a contract manufacturer that designs, engineers, and produces plastic injection-molded prototype parts and small-volume series at its single site in Übach-Palenberg, Germany. Its offering combines traditional injection molding with proprietary Print&Inject 3D-printed mold technology (including FIM / Freeform Injection Molding) to deliver functional plastic parts in series-grade materials from batch size 1, supported by co-development engineering, material selection consulting, and multi-component (plastic-metal / plastic-plastic) capabilities.

Product overview

SK Industriemodell GmbH is a single-site contract manufacturer (not a software platform) whose offering is organised as a portfolio of related in-house services rather than a unified product with separate modules. The portfolio centres on four core offerings that are typically delivered together: Injection Molded Prototype Parts (express production of functional prototypes from design/engineering support through to sample parts), Small Volume Series Production (injection-moulded niche-product batches economically viable from batch size 1), and Injection Molding Technical Implementation (co-development, design-for-manufacturing consulting and complete part/assembly engineering) — complemented by the proprietary Print&Inject technology (3D-printed injection moulds, including the FIM / Freeform Injection Molding sub-variant with dissolvable mould inserts). These four core offerings are applied vertically across dedicated industry tracks — Mobility, Medical Technology, Machinery and Plant Engineering, Construction Industry, and Other Industries (Furniture, Biotech, IT and Electronics, Garden/Leisure) — and have additionally been extended into a small range of COVID-19-era standalone plastic products such as the Ohr-Entlastungsband, the PEMask COM community mask (with PEM Motion) and the Gesichtssild face shield. All work is performed in-house at the company's Übach-Palenberg (Aachen) facility, which is ISO 9001:2015 certified.

Emerging players

• Stratasys: Stratasys is a leading polymer 3D printing company whose technologies and materials overlap with the additive-manufacturing side of SK Industriemodell's Print&Inject process. While Stratasys focuses on selling printers and materials rather than running a service bureau, its technology directly competes with the 3D-printing layer that enables SK Industriemodell's novel mold-making approach.
• 3D Systems: 3D Systems is a global provider of 3D printing hardware, materials, and on-demand manufacturing services, including plastics. Its service bureau business and AM technology portfolio overlap with the additive-manufacturing side of SK Industriemodell's Print&Inject process, though 3D Systems serves a much broader and more international customer base.
• EOS GmbH: EOS is a German-headquartered global leader in industrial 3D printing for plastics and metals, with a strong German R&D footprint in the same Aachen/Munich industrial corridor as SK Industriemodell. Its high-end polymer and metal AM systems intersect with the additive-manufacturing foundation of the Print&Inject technology.

Broad incumbents

• Ensinger: Ensinger is a German family-owned manufacturer of engineering plastic compounds, semi-finished products, and finished injection-molded and extruded parts serving medical, mechanical engineering, and automotive customers. It competes with SK Industriemodell for similar small-batch, high-material-specification plastics work but at significantly larger scale and with broader vertical integration.
• Röchling Group: Röchling is a large German-headquartered industrial plastics group producing high-performance plastic parts across automotive, medical, and industrial markets. While Röchling is much larger and broader in scope, it overlaps with SK Industriemodell in engineering plastics, multi-component parts, and serving German industrial OEMs.
• ARBURG: ARBURG is a German family-owned manufacturer of injection molding machines, robotic systems, and additive-manufactured plastic parts, including a freeformer for 3D-printed plastic components. As a broad incumbent in plastic injection molding with its own AM offering, ARBURG both supplies the equipment SK Industriemodell operates and competes for additive-manufactured plastic part work.

Direct peers

• Protolabs: Protolabs is the global leader in on-demand digital manufacturing of custom prototypes and low-volume production parts, including injection molding and 3D-printed molds. It is the closest direct competitor to SK Industriemodell in business model (prototype/small series) and target market (engineers needing functional parts fast), though at much larger scale and with automated instant quoting.
• Xometry: Xometry is an on-demand manufacturing marketplace that connects buyers to a global network of CNC, injection molding, 3D printing, and sheet-metal suppliers, with a strong focus on prototypes and small batches. It competes with SK Industriemodell for the same enterprise engineering buyers and offers a similar breadth of plastics processes, but via a marketplace model rather than a single in-house shop.
• Hubs (formerly 3D Hubs): Hubs, now part of Protolabs, provides on-demand manufacturing services including injection molding and 3D printing through a global network of vetted manufacturing partners. It is a direct competitor for the same prototype and small-series customer base that SK Industriemodell serves, with similar quick-turn capabilities but a marketplace structure rather than a single in-house facility.
• Fictiv: Fictiv operates a digital manufacturing platform for custom mechanical parts, including injection molding, CNC, and 3D printing, with an emphasis on speed and engineer-friendly tooling. It is comparable to SK Industriemodell in serving engineering teams that need low-volume, high-quality plastic parts on tight timelines, but it does so through a curated supplier network rather than an integrated in-house process chain.
