EMI

What EMI does

EMI (Étude Moule Injection), commercially known as EMI Wissler, is a family-owned French manufacturer specializing in thermoplastic injection molding of technical parts, founded in 1995 by Jean-Pierre Wissler and headquartered in Saint-Louis Neuweg, Alsace, in the France-Germany-Switzerland tri-border region. The company operates a 17,000 m² Industry 4.0 production facility equipped with 65 injection molding presses ranging from 35 to 700 tonnes and employs 180 people. Approximately 50% of production is exported internationally, and the company serves six industrial verticals: Medical & Paramedical, Renewable Energies, Electrical & Connections, Automotive, Construction, and General Industry.

The company's technical capabilities center on proprietary process technologies rather than catalog products. These include Organosheet hybrid injection molding (developed in 2015) for fiber-reinforced thermoplastic composite parts, MuCell microcellular foam molding (implemented in 2021) for weight and material savings, and an ISO Class 8 cleanroom (established 2016) supporting medical-grade production. EMI holds ISO 13485:2016 (medical devices), ISO 9001 (quality), ISO 14001 (environmental), and UL certifications, and was awarded an EcoVadis Bronze Medal in 2022. The offering spans feasibility studies, co-development, prototyping, tooling, and serial production, indicating a project-based B2B contract manufacturing model rather than standard off-the-shelf sales.

The business operates as a privately held family enterprise with €500,000 share capital and has pursued a measured external growth strategy, notably acquiring Trolitan in 2019 as its first M&A transaction following the 2018 relocation to the new 17,000 m² facility. Revenue is generated through tooling design, prototyping, and series production contracts, with the multi-vertical customer mix and roughly 50% export share supporting a diversified enterprise customer base concentrated in regulated and industrial end markets.

Core offering

EMI is a custom plastic injection molding contract manufacturer producing thermoplastic technical parts in small to large series for industrial clients. The company delivers a complete 360° Full Plastic Concept spanning design and co-development, in-house tooling, injection molding (mono, bi, tri-material), metrology, assembly, and customization, with ISO 8 cleanroom capabilities for medical devices.

Product overview

EMI is a family-owned French company specializing in thermoplastic injection molding since 1995, operating under the '360° Full Plastic Concept' which provides complete project support from idea to finished assembly. The company's service portfolio centers on six integrated departments: Étude & Innovation (design and R&D), Mécanique & Maintenance (tooling workshop), Atelier d'Injection (injection molding workshop with 63-65 presses from 35-700t), Laboratoire (metrology and testing), Assemblage (assembly services), and Personnalisation (customization). EMI operates in two main product categories: injection molding of medical devices (ISO 8 cleanroom certified) and injection molding of technical parts. The company offers advanced manufacturing technologies including 2K/3K multi-material injection, Organosheet hybrid injection molding (thermoforming and overmolding composite sheets in a single operation), MuCell microcellular foam technology, and cube mold systems for high-volume production of up to 256 cavities per cycle. Services span six industry sectors: Medical & Paramedical, Renewable Energies, Electrical & Connections, Automotive, Construction, and Industry.
