Can a mostly manual process compete with an automated spray line? Lean expert Brad Cairns thinks so, and he’s challenged a fully automated shop in British Columbia to put it to the test.
Brad Cairns, who is a principal in Quantum Lean and operates his own MDF door factory thinks his process improvements to get the most out of manual spraying can compete with all the efficiencies of an expensive automated spray line.
To prove his point, he is taking on the finishing department at Creative Woodcraft in British Columbia. They spray their doors using a Cefla automated spray system and Sun-Spot catalytic drying. Cairns uses conventional Kremlin guns in a traditional spray booth with air drying on racks, spraying one side at a time. Both shops will use a Stolbek Cosmo robotic sander in their process.
For purposes of the challenge, each shop is to sand and prime 20 MDF doors. The whole process will be filmed in real time and data will be used to compare labor and equipment costs to measure both processes on time, cost, and efficiency.
The results will be revealed in a special webinar hosted by Woodworking Network. During the webinar, I will be interviewing Cairns and Will Duggan, owner of Creative Woodcraft, to talk about both of their processes, how they decided to finish the way they do, and what their investment is. At the end of the webinar, we’ll show the videos, declare a winner, and take questions from the live audience. The webinar is sponsored by Guffey Systems, providing award-winning products for furniture, millwork, and cabinet finishing that optimize efficiency and reduce waste.
