Growing demand for the products and services of Linear Mold & Engineering necessitated the company's recent expansion to a total of 57,000 sq ft to accommodate new mold manufacturing equipment and injection molding machines. This includes the original building where Linear was founded; the 2005 acquisition and renovation of its current headquarters within Livonia, MI; and the recent addition of a new 21,000-sq-ft manufacturing facility.

Conformal cooling hot for Linear Mold

Growing demand for the products and services of Linear Mold & Engineering necessitated the company's recent expansion to a total of 57,000 sq ft to accommodate new mold manufacturing equipment and injection molding machines. This includes the original building where Linear was founded; the 2005 acquisition and renovation of its current headquarters within Livonia, MI; and the recent addition of a new 21,000-sq-ft manufacturing facility. This expansion allows for additional manufacturing capacity and capabilities in molding, quality control and dedicated assembly areas. Linear's Livonia headquarters houses the design, engineering, tooling and additive manufacturing departments.livonia-mi-linear-mold-and-engineering-about-us-2.png

"We've been growing consistently year-on-year, and had outgrown the original building where we started the company," said John Tenbusch, President and CEO of Linear. "We've also increased our injection molding capacity over the last few years and now have nine machines, and are planning to add two or three more presses in the next calendar year."

Currently, Linear operates molding presses ranging in size from 33 to 1000 tons clamping force, and plans to add more capacity in large-tonnage presses to accommodate demand for large-part molding from its customers. Linear added a 10-ton overhead crane in the new location to handle the larger-sized molds. While most of the presses are used for mold tryouts, validation and prototype runs, Tenbusch says Linear is experiencing increased demand for production runs from its customers.

"We have diversified our customer base to include not only automotive, but aerospace, agricultural, non-clean room medical device, military and industrial markets," Tenbusch stated.  "Additionally we're developing some of our own plastic products that we'll be bringing to market in the near future."

Linear has developed a niche in conformal cooling technology using the Direct Metal Laser Sintering (DMLS) technology from EOS. The company recently added DMLS capacity that now totals four EOS M270 machines to help meet demand. "We have developed an expertise in the design and build of tooling inserts with conformal cooling channels for other mold shops and OEMs, and that business is growing dramatically," Tenbusch comments. "There's a tremendous amount of interest in the conformal cooling technology due to the demand for faster cycle times that reduce manufacturing costs."

Linear has also added Moldex 3D CAE software for in-depth injection molding simulation to maximize the advantages of conformal cooling in the injection molding process. Other machinery additions include a Makino A92 and a Makino F-5, bringing the total to 11 CNC machining centers. Linear currently employs 82.
