![]() Models were easier to view and comprehend downstream. Later, the use of wireframes was replaced by solid models, allowing bases, plates and other mold components to be represented as separate solids. The programmer would study prints to isolate the distinct features of the various machined parts that make up the mold. Mold assembly designs used to arrive as wireframe CAD models, he says. Delivering molds quickly used to be far more difficult for the shop, he says, and the reason had more to do with programming than it had to do with machining. ![]() He both programs machining work and oversees that work at the machining center. Jeff Wendtlandt is a senior mold build technician with this shop. Among the shop’s time-critical work are the repair and replacement jobs for molds that are needed urgently, because the production of some plastic component is being delayed for want of that mold. Jobs that remain in-house include molds that are difficult to outsource-along with molds that are just plain difficult. As the company has become steadily more proficient at outsourcing mold making to suppliers, the mission of this shop has changed. ![]() The shop occupies the fifth floor of the Milwaukee, Wisconsin, headquarters for Rockwell’s Allen-Bradley brand. Making a mold demands not just machining time, but also programming time-and much of that programming may not even involve the core and cavity.įor a small mold shop within Rockwell Automation, the response time for delivering a mold has steadily become more critical. ![]() However, saving time from these cycles can only go so far significant time is also lost elsewhere. A faster machine following suitable tool paths can allow machining cycles for cores and cavities to proceed considerably faster. Changes that address the leadtime required to make a mold tend to focus on the machining cycle.
