In Erchinger's assembly department in Tuttlingen, highly qualified surgical instrument makers assemble every instrument carefully by hand — inspected, documented, and backed by a quality promise: 100% function of every assembled instrument.
The assembly of surgical instruments is the final manufacturing step, in which individual precision components are assembled by hand into a functional instrument by qualified surgical instrument makers. At Erchinger, this includes the assembly of complex instruments, the integration of fine-mechanical and moving components, and the final inspection of functionality, fit and safety — before packaging, marking and delivery.
"Quality begins in assembly — craftsmanship from master hands. We guarantee 100% function of every assembled instrument."
Craftsmanship precision, tested function and complete documentation — Erchinger handles final assembly of surgical instruments from prototype to series.
From assembly of components to delivery — our services in detail.
Assembly of complex instruments from multiple precision components to customer drawing or development specification.
Multi-part instruments with a ratchet function, joints or sliding mechanisms are assembled by hand step by step and continuously checked for fit.
Installation of moving and fine-mechanical components such as joints, ratchet functions and spring mechanisms.
Springs, ratchets and joints must show exactly the intended force and movement after assembly — our surgical instrument makers check this individually on every instrument.
Inspection of functionality, fit and safety for every single assembled instrument.
Every instrument is checked for smooth movement, secure fit and flawless appearance before leaving assembly — the basis for our 100% function promise.
Complete documentation of every work step in the Device History Record (DHR) for full traceability.
From component batch to final inspection, every assembly step is recorded — so every delivered instrument can be traced back to manufacturing.
Preparation for delivery including packaging and marking to customer requirements.
Whether individual packaging or set assembly: we package and mark to suit your target market and your requirements for sterilisation and logistics.
Flexible assembly capacity from prototype assembly to ongoing series production.
Our assembly department scales from single-unit prototype production to continuous series assembly — with no difference in quality between the first and the thousandth piece.
Five steps from inspected individual parts to delivery.
We receive the inspected individual parts released from manufacturing into assembly. Every batch is documented and fully traceable. This means every assembly begins from a basis of verified quality.
Qualified surgical instrument makers assemble the instruments carefully by hand to the customer drawing. Fine-mechanical and moving components are fitted precisely. Every step follows a defined work standard.
Every assembled instrument is checked for functionality, fit and safety. Moving parts must operate smoothly and lock securely. Only flawless instruments pass this test.
Every assembly and inspection step is fully recorded in the Device History Record (DHR). This creates full traceability for every single instrument. This documentation is part of our certified quality management system.
After final release, every instrument is packaged and marked for delivery. Delivery is fully documented and made under your brand. This completes the circle, from manufacturing to a ready-to-use product.
