Spinnitech's product packaging machine has been fully documented throughout its development, in an effort to provide total customer satisfaction. Although we are currently in the prototype phase for this product, all primary and supplementary documentation has been provided. We like to walk with our customer, through every step of the design process. Because at Spinnitech you don't just get a solution, you get friends solving problems.

Engineering Trade Studies
Nick Birk: Proposal / Report
Description: Uses solid mechanics to examine forces on the moving cup and resulting stresses.
Caitlin Kopf: Proposal / Report
Description: Determines necessary geometry of crank-slider mechanism for cup dispensing system. Analyzes acceleration of the slider using the method of kinematic coefficients.
Mike Mack: Proposal / Report
Description: Develops necessary geometry for HDPE support strut in capping mechanism.
Michael Wicks: Proposal / Report
Description: Determines necessary geometry for pellet dispensing mechanism.
Kyoko Yoshida: Proposal / Report
Description: Determines necessary geometry of cam follower mechanism for cup dispensing system. Results will be compared to crank-slider trade study to determine which mechanism to use.
