DiaCom Corporation designs and manufactures innovative, cost-effective molded diaphragms critical to the operation of essential industrial systems and equipment.
About six years ago, industrial diaphragm manufacturer, DiaCom Corp. (DiaCom) initiated a shift in its approach to tool design and manufacturing. With a great customer reputation already in place, the time came to upgrade the company’s technologies. The goal: expand into new markets.
The Amherst, New Hampshire-based company designs and manufactures innovative, cost-effective molded diaphragms critical to the operation of essential industrial systems and equipment. DiaCom not only produces diaphragms but designs and builds the tooling to manufacture them. The company staffs design and tool departments as part of its business model.
The new technology shifts have allowed entry into new industries requiring more complex diaphragms as well as parallel markets. Those industry targets include aerospace, irrigation, automotive, oil, gas, and medical customers. “We wanted to grow dynamically by offering more intricate, cutting-edge products and also expand into new geographic markets in China and Europe,” says Mike Grywalski, manufacturing engineering manager at DiaCom.
Expansion required more advanced software technology. Customers were starting to come to DiaCom with 3D models to work from. The company was using 2D computer-aided design (CAD) software, producing “old-school” drawings that couldn‘t fully define some products. DiaCom recognized the problem and decided to shift its design paradigm.
Grywalski’s shopfloor background helped him realize the need to bring the tool group on board with any CAD technology changes. With many years of CAD and computer-aided manufacturing (CAM) software experience, he recalled compatibility, communication, and technical support issues when using software from two different vendors.
“We wanted to bring the tooling group on board with our plans,” says Grywalski. “We wanted to implement CAD and CAM applications from one software company so we could get one-stop support.”
The company selected Solid Edge® software for 3D design and Solid Edge CAM Pro software for manufacturing, both from product lifecycle management (PLM) specialist Siemens Digital Industries Software. DiaCom relies on Siemens solution partner Maya HTT for implementation, training and system support.
DiaCom evaluated multiple CAD systems including SOLIDWORKS® software, AutoCAD® software, Inventor® software, Pro/ENGINEER® software, and Solid Edge. “While there were many software programs available, we selected Solid Edge because of available support from Maya HTT as well as from Siemens’ Global Technical Access Center organization. This support network paid off well as we initiated changes.” Besides the 24/7 support for both CAD and CAM questions, Maya HTT and Siemens Digital Industries Software helped DiaCom identify postprocessors for its machine tools and solve other hardware/software interface challenges.
DiaCom determined that the Siemens Digital Industries Software technology was impressive and pricing was competitive. “Solid Edge gave us the technological capability to design the more complex parts required by existing customers as well as the other new customers we work with,” says Grywalski. “Today‘s changes are often more challenging and can take longer. With 3D, it’s easier to make customer-requested design changes than it was with traditional 2D software.”
DiaCom has started to use the synchronous technology capability of Solid Edge, applying the simplicity of direct modeling with the control of parametric design. The company continues to evaluate synchronous technology as well as traditional ordered design. “In some cases, the ordered approach makes the most sense,” Grywalski says. “At other times, the synchronous approach seems best. Either way, we are seeing a reduction in design time and higher accuracy, both of which have a positive impact on manufacturing. For example, on a recent complex mold project, the use of Solid Edge modeling was 25 to 30 percent faster than traditional 2D design and was more accurate.”
Making modifications to existing diaphragm designs is quite common at DiaCom. By using synchronous technology instead of traditional history-based processes, DiaCom has experienced a reduction in revision time by up to 50 percent on recent design work.
DiaCom is designing programs to create automated part and tool models based on variable tables in Solid Edge. By applying new business engineering processes, these programs are being used by designers to accelerate design without sacrificing accuracy. Though this is in the early stages of development, the company has already experienced significant benefits with the new approach.
For its computer numerical control (CNC) programming tool, DiaCom selected Solid Edge CAM Pro from Siemens Digital Industries Software. DiaCom uses Solid Edge CAM Pro to program its Okuma CNC lathe and Fadal CNC mill, among other pieces of equipment to machine the compression molds that are used to manufacture the diaphragms. DiaCom’s tool room lead pioneered the use of Solid Edge CAM Pro to program the machine tools. Additionally, the mill and lathe machine operators have been trained in the use of Solid Edge CAM Pro to program the machine tools.
“With 3D CAD in place, we have been designing some pretty complex parts for various applications. Many customers prefer not to use traditional diaphragm designs,” Grywalski says. The more sophisticated designs also required Solid Edge CAM Pro 3-axis machine milling and turning programming capabilities.
The combination of Solid Edge and Solid Edge CAM Pro has provided “a seamless transfer of tool design communication between our design group and the shop floor,” says Grywalski. DiaCom evaluated four CAM packages and is pleased with its choice of Solid Edge CAM Pro.
Other results from the technology upgrades and market expansion included building a new tooling complex and expansion of the design and tool manufacturing staff by about 60 percent.
“Solid Edge and Solid Edge CAM Pro have made a significant difference by improving our technical design and tool-build capabilities,” said Grywalski. “They helped DiaCom provide complex products, which would not have been as easily made several years ago.”
