    Special Applications

    (13)

    Positrol will analyze your application and offer the right solution.  We use a six step proprietary process to design a workholding device or system that will meet your goals.

    1. First, we must understand your needs: tolerance requirements, operations performed, machine used, actuation method, budget and time constraints.
    2. Then we will Analyze the part and material including FEA to determine optimum clamping location and force.
    3. Determine the best solution.
    4. Design for your review.
    5. Manufacture.
    6. Validate at our facility and follow up at your facility with local representation.
