A quality design is one that has value to customers. In order to provide quality designs at Delta, we have to know what the customer considers valuable and link that to the most effective design to meet those needs.

The “house of quality” is a basic design management tool used frequently as part of quality function deployment (QFD). Originating in 1972 at Mitsubishi’s Kobe shipyard site, the house of quality has been used successfully by Japanese manufacturers of consumer electronics, home appliances, clothing, and for services like swimming schools and retail outlets.

The Harvard Business Review describes the House of Quality as “a kind of conceptual map that provides the means for inter-functional

planning and communications. People with different problems and responsibilities can thrash out design priorities while referring to patterns of evidence on the house’s grid.”

Recently, the crew at Delta Development finished construction on an 11’x13x11’ thermal test chamber. The chamber is capable of testing a variety of machines like generators, small vehicles, refrigeration equipment, and aerospace equipment, and allows us to run temperature and humidity tests from -25°F to 160°F. In addition to temperature and humidity, the LabView data acquisition system can monitor pressures and network data like CANBus or ModBus.

Delta has acquired a Carbide 3D Shapeoko CNC router and we’ve already begun using it to build molds for insulating our refrigerators. A CNC (computer numerical control) router is a computer-controlled cutting machine used for cutting various hard materials. It helps to reduce the time spent in production and the frequency of errors, making it a very effective tool. We worked with Hawk Ridge Systems to develop a custom Post Processor to make Solidworks CAM work with the Shapeoko, allowing us to take parts straight from CAD to our router. You can find the post processor we helped to test here: https://hawkridgesys.com/products/cam/post-processors. Check out the time lapse to see a test cut of the Delta logo out of acrylic.
