Weiss North America Inc. of Willoughby, Ohio, provided its TC series rotary tables to the plastic plumbing parts maker LSP Products Group Inc., which runs a plant with 11 injection molding machines in Carson City, Nev.
LSP was developing two new small-sized plumbing products that were to be produced in ultrasonic- and spin-welding operations, and officials were looking for new solutions to replace their manual assembly line processes. The product is a new in-line hammer arrester for water pipes, made out of polymers instead of the traditional copper.
The solution was Weiss rotary indexing tables.
Originally, LSP was planning to build its own automation internally, but the Weiss sales and engineering team provided them a configuration proposal based on the TC series tables. A key design aspect that the rotary tables and the welders faced was overcoming the large downward forces (400 pounds) from the servo-driven welders, to melt plastic that was extracted onto the index table's tool plate, in repeated production.
To overcome that challenge, an anvil back-up support was designed underneath to absorb the intense loads from the welders. This also promotes longer production life for the tables and the plates, Weiss said.
Weiss completed and shipped the first unit in April, then a later one in October.
