When it is seen how Protolabs uses a System 3R pallet system in the ever-tougher ‘lead time race’, it is easy to see why the company asserts that it is the world’s fastest supplier of both CNC milled and injection moulded components.

Regarding speed, operational reliability and repeatable precision, Protomold and Firstcut, the two elements in the company’s operations, both benefit greatly from System 3R’s Macro system. This applies equally to the manufacture of moulding tools and the milling of components.

All workpieces are mounted on Macro pallets. Thanks to the properties inherently offered by the patented 3Refix system’s guaranteed positioning, Protolabs can move the pallets from one machining process to another without jeopardising precision, no matter how many such moves the total process requires.

“Over the past four years, System 3R has undoubtedly helped us cut lead times considerably, if not to say dramatically,” reveals Lee Ball, production director.“Speed is the essence of our mission to supply customers with injection moulded or machined components. Protomold is really fast in supplying injection moulded parts to customers. We would not be able to produce moulding tools fast enough if we couldn’t first make the necessary graphite electrodes. Macro is with us all the way. Furthermore, the system is so easy to use.”

By combining the production processes in its Haas CNC milling machines and Agie-Charmilles die-sink EDM machines, Protolabs can rapidly supply parts made in the desired material. This is vital not only in each prototype project but also in the production of test pieces and the reproduction of unavailable, obsolete or faulty components.
