Tessy Plastics Focus on Precision Measurement
Back Ground of Tessy:
Tessy has over one million square feet of manufacturing and warehousing space and is looking for more. The company has major facilities in multiple central New York locations and several smaller operations overseas. To this day, the business operates and prospers as a private company under the leadership of the Beck family.
When Mark Towers joined Tessy Plastics in 2005,his mission as Director of Quality was to upgrade company’s quality capabilities. Today, the Quality department is comprised of 77 employees who support quality interests on seven production shifts, nearly 365 days a year. The quality program is a major differentiator when prospecting for new customers, allowing the company to aggressively and confidently move into new vertical markets that require high precision capability.
Quality systems at Tessy have a high degree of automation and the company uses SPC (Statistical Process Control) to qualify the molding process using dimensional data collected by their numerous QVI® measurement systems.Currently, Tessy Plastics has 20 OGP® SmartScope® video measurement machines deployed at multiple molding locations, including inside their ISO (14644-1) Class 8 production cleanrooms. Once the mold tooling has been dimensionally qualified, measurement data is collected from production samples and automatically entered into the company’s SPC program,which monitors process consistency. “Our customers have realized higher productivity in their own plants because they know they can rely on compliant product from Tessy. Their assembly processes run better because our products are so consistent. We do that through accuracy and process control that the OGP machines help us maintain,” according to Towers.To further the company’s engineering capability, Tessy recently purchased an OGP SmartScope Quest™ 450, running ZONE3®, OGP’s fl agship 3D measurement software. This powerful measurement system is used by the Engineering Development Group within the Quality Department to qualify new molds and tooling prior to production. Using 3D CAD models supplied by their customer, Tessy is able to compare mold tooling features directly to features on the customer engineering drawing, all without having to produce a single part. This minimizes set-up and molding machine time spent on prototypes,only to fi nd out that tooling must be pulled off the machine and reworked in order to produce forming parts.According to Towers, “the SmartScope Quest will be utilized primarily by our tooling quality engineers for development because of its high accuracy, but it also has the versatility to be used by our production quality technicians when necessary.” The SmartScope Quest has a QVI TeleStar® Plus Laser.A TTL (through-the-lens) laser enables scanning a laser spot over a surface, providing contour details as part of a measurement routine, and the system also has a QVI Feather Probe™- a sensitive resonance probe measuring very small features that may be inaccessible to other measurement sensors.One business segment that the company has focused on is micro-molding and micro-assembly for the medical equipment market. Holding the tight tolerances required by a highly regulated industry is the goal throughout the manufacturing process:injection molding, measurement, and micro-assembly which includes robotic pick-and-place machines located in a cleanroom production environment.Tessy’s ability to manufacture and measure highly sophisticated and accurate micro parts has allowed the company to fi nd success in new markets unreachable by traditional injection molders. “We are gaining ground in niche markets both domestically and in Europe, and OGP brand measurement systems have helped give us the precision capability to compete in those markets. The new micro-assembly orders that we win indicate we’re gaining market share, usually at the expense of one of our competitors,”commented Towers.Mark Towers has been a long-time champion for the OGP brand at Tessy, and for good reason,“OGP machines are very reliable. Software is rock solid. Super easy to program. Over the years, I’ve bought nearly 30 OGP machines I’m addicted.”
