Automated Production Today, automated production is essential. Neither volume nor product consistency can be achieved in any other way. Increasing production in a cost-effective manner is a difficult and complex undertaking. The project engineer overseeing such a project must have strong support from management

Defined as an impact, characterized by sudden and substantial change in velocity. Shocks in the distribution environment: Accidental and deliberate drops during manual handling Drops from chutes, conveyors, and other machinery Falls from pallet loads Sudden arrests on conveyors Impacts occurring when vehicles hit potholes, curbs, or railroad tracks

Test Method for Product Fragility A shock machine is used to generate a damage boundary curve A vibration system is used to map out the natural frequencies of a product

Throughout the distribution system, packages are manhandled and mishandled in various ways: dropped, thrown, kicked and otherwise roughly abused; fall from conveyors or forklifts and crash to the floor;
