Carlisle FoodService Products is a leading manufacturer of foodservice, sanitary, and healthcare products and equipment. With award-winning brands like Dinex® healthcare foodservice products, DuraLast™ table coverings, and Sparta® brushes, the company is committed to designing and manufacturing professional grade products with the people who have to use them every day in mind. Carlisle products provide real value and facilitate smooth-running, profitable operations.
Many of Carlisle’s products are manufactured using plastics injection-molding techniques. Until 2010, the foodservice products manufacturer used Pro/ENGINEER® 3D design software to design its products and the molds from which they are made. However, as competitive pressures compelled Carlisle to boost productivity and throughput, and shorten development and manufacturing cycles, company management decided to investigate easier-to-use, more affordable, and more flexible 3D design software, according to Research and Development Engineer Brad Tilman.
“The company decided to switch over from Pro/ENGINEER to SOLIDWORKS 3D design software for several reasons,” Tilman explains. “Ease of use was an important requirement, as was cost. We also liked the fact that SOLIDWORKS provides a range of integrated design and engineering solutions that we can add as we need them. We added SOLIDWORKS Plastics software and SOLIDWORKS PDM Professional in 2013 to improve product design for manufacturability, reduce the volume of prototype molds required, and streamline our development processes and workflows.”
Carlisle standardized on SOLIDWORKS Premium design software because it is easy to use, provides critical mold development and analysis tools, and includes photorealistic rendering and SOLIDWORKS eDrawings® communications tools. The company added SOLIDWORKS Plastics and SOLIDWORKS PDM three years later to gain additional productivity benefits.
“SOLIDWORKS software is ideally suited to the type of products that we design and manufacture,” Tilman stresses. “For example, I run a draft analysis on every single part that I design, which ensures that we have sufficient draft for manufacturability well before development of the injection mold.”
BRINGING INJECTION-MOLDING SIMULATION IN-HOUSE
Carlisle added SOLIDWORKS Plastics injection-molding simulation and analysis software to bring this function in-house, lessen the company’s reliance on outside injection-molding consultants, and improve development and production efficiency. “The complexity of our designs continually increases, so we need to be able to handle all aspects of mold analysis internally,” Tilman notes. “For example, I designed a cup-lid holder for use in a dishwasher that was fairly complex, with ribs, a crazy flow pattern, and a two-drop gate on the mold.
“With SOLIDWORKS Plastics software, I ran some successful mold-filling simulations to validate that the part could be manufactured, as well as where the weld lines would be,” Tilman continues. “I’ve also run some successful simulations of cooling channels on a mold to understand the cooling of a part. Ensuring that material will flow in and fill out the mold without being pressure-limited in the machine and checking where the parting lines are is vital to everything that we do.”
