Résumé : |
Otto Klumpp GmbH has for many years processed, for example, highly transparent PC and high-performance plastics such as PPSU into sophisticated medical products. Since cleanliness and hygiene are essential for implants or blood-carrying systems, injection molding production and parts assembly are performed in the cleanroom. DLC-coated components also play an important role in in-house mold production. |

- Ground to an undersize before DLC coating
- FIGURES : 1. For filter, Otto Klumpp uses resilient fabrics and stainless steels or alloys (Monel). The minimum mesh size for metal meshes is aprox. 5µm, for plastic meshes, it is approx. 1µm a thousandth of a millimeter - 2. The 40mm-long injection needles with a diameter of 1.6 mm must be filled without core deflection - 3. An autotransfusion reservoir significantly reduces the amount of donated blood required, and thus reduces the risk of AIDS or hepatis. Directl after injection molding, the scale is labeled with an accuracy of 0.1 mm - 4. In the cell, a six-arm robot grasps a tubular fabric and transfers it to a cassette system with conical core - 5. When the mold incorporates a special technical solution, Otto Klumpp Keeps, the injection mold production in house. Here, an 8-cavity mold (with DLC coated ejectors) for an handle sleeve. With the illustrated un-screwing spindle unit, the internal thread of the dental product is demolded in the closed mold - 6. In many mold, Otto Klumpp uses DLC-coated ejectors. Not quite sohard, but ideal for use in the cleanroom : the a-C:H:W coating (DLC doped with tungsten) on the fine centerings |
