Diener AG Precision Machining

What Diener AG Precision Machining does

Diener AG Precision Machining (DPM) is a Swiss precision contract manufacturer founded in 1955 and headquartered in Embrach, Switzerland. The company operates a 5,000 m² production facility equipped with 100+ CNC machines — including 22 Citizen M16 Swiss-type turning centers, multi-axis turning up to 9 axes, 5-axis milling centers (BUMOTEC S191, DECKEL MAHO DMU-50/60, FEHLMANN Versa 645, MORI SEIKI NV-5000), and ZEISS/KEYENCE metrology systems — supported by an ISO Class 7 clean room and ISO 13485:2016 certification. It produces precision components and assemblies for OEM customers across dental implants, orthopaedic and spine implants, ophthalmic surgical instruments, surgical robotics gears and transmissions, surgical power tool components, and high-tech/lithography applications, with batch sizes from prototyping to 100,000+ units in materials including titanium, stainless steel, PEEK, aluminum alloys, and plastics.

DPM generates revenue primarily through one-time B2B contract manufacturing engagements, supplemented by professional services for value engineering (Design for Manufacturing), prototyping, and end-to-end supply chain management. A growing share of work flows through its ISO 7 clean room for validated cleaning, assembly, blister packaging, UDI-compliant laser marking, and sterilization coordination, with a new integrated Clean & Pack Line announced in February 2025. The go-to-market is direct enterprise field sales to OEM partners, augmented by the Acrotec Medtech network following DPM's 2019 acquisition by Acrotec Group; pricing is custom and based on complexity, materials, tolerances, and volume, with 30-day net payment terms and a 50% cancellation fee on customer-initiated cancellations.

DPM serves an enterprise customer base of medical device, surgical robotics, and high-tech OEMs globally (with operating geographies listed across Switzerland, Singapore, and the USA via the Acrotec network). Approximately 200 employees support operations as of 2023. The company has been recognized with Deloitte Switzerland's Best Managed Companies awards in 2022 and 2023 and Great Place to Work certification in 2023. Revenue is not publicly disclosed; the company is a wholly-owned subsidiary of Acrotec Group and reports no independent financials.

Core offering

Diener AG Precision Machining (DPM) is a Swiss B2B contract manufacturer that produces ultra-precision CNC-turned and CNC-milled components for medical technology and high-tech industries. The offering covers the full value chain from prototyping and value engineering through precision machining (multi-axis turning and 5-axis milling), surface treatment, ISO Class 7 clean room packaging, and quality-assured delivery to OEM customers in medical, surgical robotics, dental, ophthalmology, and high-tech sectors.

Product overview

Diener AG Precision Machining (DPM) is a Swiss precision contract manufacturer serving OEMs in medical technology and high-tech industries. Its offering is structured as an integrated platform of manufacturing capabilities anchored by CNC turning and CNC milling (the core manufacturing engine), supplemented by five specialist capabilities — surface treatment and laser marking, ISO 7 clean room contract packaging, and quality assurance — which together enable the company to deliver fully finished, inspected, and packaged components. On top of the manufacturing platform, DPM layers three value-adding services: Value Engineering (design optimization), Prototyping, and Supply Chain & Vendor Management. The product portfolio covers six precision component categories: Dental Implant Components, Orthopaedic Implants & Instruments, Ophthalmology Surgical Components, Precision Machined Gears & Transmission Parts, Surgical Power Tools Components, and High-Tech Precision Components. The most recent addition is the Clean & Pack Line (announced February 2025), which consolidates cleaning, ISO 7 blister packaging, and sterilization coordination under one roof for a fully integrated machined-to-sterile offering.
