When I started out in the rotational molding industry more years ago than I care to admit, my first “sales trip” was to meet with a long-time rotational molder. The shop wasn’t very large, clean or lean and the office was even worse – truly an entrepreneurial enterprise — the type that the industry was built on and in some cases is still known for. It was during this visit that I had my first technical training in the rotomolding process as the grizzled veteran put his hand on my shoulder, took the cigar out of his mouth and uttered these words of wisdom; “Young man, if you want to succeed in this industry, you only need to remember two things – 1 inch radii and 45 degrees draft.”
Back then we also worked with hand-drawn 2-D bed-sheet sized prints sent to us thought the U.S. Postal Service in order to generate quotations for molds using nothing but a pencil, a calculator and “process knowledge.” Quotes were then typed up on a triplicate form and a copy mailed back to the prospective customer. On average, the tool quoting process took upwards of seven to 10 days, depending on how the mail was moving.
Since those bucolic simpler times we have seen the development and application of all sorts of great technology: the fax machine, CAD part designs, e-mail, rapid 3-D part modeling, 3-D printing, process-simulation software and CNC-cut molds, just to name a few. Many in our industry have also adopted the principles of lean manufacturing and Toyota’s model of early collaboration of supply chain members. All of this to serve a world that is getting smaller and moving more quickly than ever before.
The very discussion of being tech-savvy and doing business differently in order to keep pace in a global market was the theme of an SPE Rotational Molding Division Topcon in May of 2012.
With all of these tools of technology available why has so much in the rotational molding industry remained unchanged. (Click here to read: Building A Better Road to Roto) Why does tooling in particular continue to be treated as a commodity? Could the availability of all of this technology displace accumulated knowledge, creating casualties of change for change sake? Just because a mold can be CNC cut does that mean it should be? Is it possible for the application of technology to become “over-processing” in certain cases?
I look forward to discussing these technology-related topics in greater detail in future blogs.
