Complementing Laser Sintering with EDM

Conformal cooling is a hot topic lately, and for good reason. By ensuring consistent temperature throughout the molding cycle, conformal cooling speeds production, improves part quality and reduces costs.

That’s great for the customer, but the potential return for the manufacturer diminishes with a longer production process and heavy workload. That’s been the case at Linear Mold & Engineering, a Livonia, Michigan manufacturer that has been using direct metal laser sintering (DMLS) technology from EOS to create conformal cooling channels for nearly a decade. Recently, demand increased to the point where the company was compelled to increase production efficiency for this lucrative market.

The problem wasn’t with the DMLS machines themselves—in fact, the company may have already made good on plans to add additional machines by now. Rather, the issue concerned surrounding processes: sawing inserts off the base plate, grinding off the base plate remnants, and finish-milling the inserts to size. Now, all of these operations are performed in a single setup on a Mitsubishi MV2400 wire EDM from MC Machinery Systems. Moreover, the operations can be performed on as many as five plates of conformal-cooled inserts at a time. Read this article to learn more.

Linear also recently appeared in Additive Manufacturing, a quarterly supplement produced jointly by MoldMaking Technology and the editors of sister publication Modern Machine Shop. That article details how the shop is leveraging customer service, education and training to grow its additive manufacturing business.
