Mantle Unveils Collaborations Based on its TrueShape Printing Technology

August 4, 2022


Mantle-AMUG-tool-inserts-medicalMantle announced collaborations based on 3D-printed tooling inserts produced via the company’s TrueShape metal-AM technology. This includes reported work with Westminster Tool that demonstrated the value of conformal cooling, with Wepco Plastics that demonstrated better part finishes than achievable with aluminum tooling, and with Precision Laser Technology and Craftsman Mfg. showing that Mantle’s H13 material machines and welds similarly to conventional H13 tool steel.

In each collaboration, Mantle tool components printed with the company’s H13 Flowable Metal Paste material showed equivalent performance to conventional H13 tool steel. Together, these studies underscore the benefits of Mantle’s TrueShape technology, according to company officials, in quickly printing precision components for prototype and production tools, molds, and dies—and advancing from designs to molded parts in weeks. 

Mantle’s hybrid technology, additive and subtractive machining with sintering, works together with its proprietary Flowable Metal Paste in creating high-precision inserts. This singular application focus on toolmaking solutions enables Mantle to optimize the value of its technology for toolmakers, company officials report. 

For example, earlier this year, Mantle teamed up with Westminster Tool, Plainfield, CT, to help them produce tooling inserts to enable quick molding of medical forceps sample parts. Westminster Tool wanted to mold the forceps from a highly glass-filled, bio-based PA11 that is focused on surgical-device applications. According to Eddie Graff, Westminster Tool manufacturing engineer, a traditional aluminum prototype tool would present difficulties in molding the material. Mantle proved a solution.

Graff designed the tool inserts to include conformal cooling channels.

“These are more effective at controlling the cavity temperature, which is critical to molding this particular material,” he says. Mantle then printed the inserts in 86 hr. “In the end,” Graff offers, “it took us three weeks to go from design to FOT, quality medical parts on a prototype tool.”

Mantle’s metal-AM inserts (pictured) held a tolerance of +/- 0.0015, and, because they were made with H13 steel, they allowed Westminster to add a subgate to allow molding of thousands of parts without the risk of gate erosion.
