STAUFF - Specific Clamps for Special Applications

ECONOMIC PRODUCTION OF CUSTOM SOLUTIONS Conductive plastic fasteners are required for bulk goods han- dling, among other things. Friction in the powdered, granular or large-piece materials produces a slight electrostatic charge. This has to be dissipated in a controlled manner in order to avoid uncontrolled discharge. Bulk goods handling, as well other industries, therefore use tubes and hoses made of electrically conductive plastic. They are typically fastened with metal clamps, which per se are conductive, but have well-known drawbacks such as lower vibration resistance and higher noise generation. Until 2023, STAUFF mechanically machined small numbers of clamps from conductive polyethylene sheet material at customer request. For larger production runs, injection moulding is more economically viable. A suitable plastic granulate was needed for this application, and STAUFF engineers once again found a solu- tion: The PP-EC (electrically conductive) granulate used since 2023 has a lower surface resistance (< 10^4°) than the propylene material used as standard and is therefore not insulating, but dis- sipating. The previously expensive custom production is now available at much more economical conditions. FAST PRODUCTION OF INDIVIDUAL CLAMPS For small quantities, prototypes or small production runs, STAUFF also offers 3D printing. The question here is: Is injection moulding a viable process or is 3D printing more cost-effective? 3D printing offers additional advantages, namely straightforward online ordering and fast production and delivery. Users upload a CAD model of the required fastening solution to the STAUFF plat- form and select from options such as material, colour and quan- tity. With a process known as “rapid quoting”, there is no need to wait for a quotation. Once the printing order has been placed, the cooperation partner – one of the market leaders in additive man- ufacturing and industrial 3D printing – starts production and usually delivers the 3D-printed, fully functioning and durable clamps within a matter of days. VALUE ANALYSIS OF HYDRAULIC LINE SYSTEMS STAUFF offers OEMs analysis of hydraulic line systems and con- sultations for optimisation: VAVE – “Value Analysing, Value Engi- neering”. This process is based on the competence of STAUFF as a one-stop supplier for all components of hydraulic line systems from in-house development and manufacturing. The first step is a value analysis that examines a system (mobile or stationary) or individual function areas. This results in recommendations for an optimal line system, for example with improved guiding and fastening of tubes and hoses. The processes also analyses detachable connections in the line systems, with a focus on economic efficiency as much as on safe- ty, ergonomics, flow optimisation, accessibility and service life.
