What Blosch does

Blösch AG is a Swiss family-owned surface coating services company headquartered in Grenchen, founded in 1947 and now in its third generation of family leadership under co-CEOs Pascale and Patrick Blösch. The company operates as part of BCI Blösch Holding AG, which also owns sister companies Liss a.s. in the Czech Republic (PVD thin-film technology) and Platit AG (coating systems manufacturing). Blösch AG delivers contract coating services and a broad proprietary coating portfolio under one roof — including the FeinAl, Microline, ACUREA, and DLC product lines — to B2B customers across luxury watches, medical devices, aerospace and defense, tools, and optics and sensors.

The business model combines fee-for-service contract coating with the sale of coating equipment through sister company Platit AG, which has placed 550+ systems worldwide. Customer access in regulated end-markets is enabled by ISO 9001:2015, ISO 14001:2015, ISO 13485:2016, and RJC certification (held since 2017). The Switzerland-Czech Republic footprint supports both high-precision Swiss watch and medical device work and EU-shored PVD volume. Go-to-market is direct B2B, specification-driven, and tied to long-cycle qualification in regulated supply chains; pricing is project- and performance-based rather than transactional volume.

The holding structure is the central architectural feature: Blösch AG provides the services backbone, Liss a.s. supplies PVD thin-film capabilities in Central Europe, and Platit AG anchors the equipment side — collectively producing a vertically integrated coatings platform unusual for a mid-sized Swiss industrial firm. The 75-year operating history, multi-vertical customer mix, and ongoing proprietary product launches (FeinAl, Microline, ACUREA) indicate a mature but actively maintained technology stack, with co-CEO Pascale Blösch's election to the Swissmem Council marking recent engagement in broader Swiss industrial policy.

Products and services

• Job Coating Services Authentic coating services for individual components supplied by customers: Blösch applies a broad portfolio of functional and decorative coatings (PVD, DLC, electroplating, laser treatment, soldering, photolithography) to customer-provided parts. Service is delivered across all four priority markets — watches, medical devices, aerospace & defense, and optics & sensors.
• Components (Coated Components) Standard coated components and parts with ready-made Blösch coating solutions applied, including DLC coatings for tools and sliding contacts. Available to order directly from the company.
• Customized Solutions Tailored coating solutions developed in partnership with enterprise customers from substrate selection and coating development through validation, logistics, and series production. Includes substrate procurement and overall quality and logistics responsibility.
• Blaktop DLC Coating Blaktop is a DLC (Diamond-like Carbon) coating branded by Blösch for elegant black finishing on watch parts (cases, components, etc.); a layer little more than a micron thick that protects and beautifies modern watch elements. Suitable for all substrates including steel, brass, carbide, ceramics, and sapphire.
• Anthratop DLC Coating Anthratop is a DLC coating variant by Blösch for decorative and functional embellishment of watch parts, paired with Blaktop in the company's DLC decorative portfolio.
