High-Speed Servo Spin Welder HS-OSW
For Joining of Small-Diameter Parts
Forward Technology, Cockato, MN, USA, a manufacturer of standard and custom plastic welding equipment and testing systems, has announced the introduction of a new high-speed orientation spin welder designed for smaller diameter and more difficult applications that require delivery of rotational speed at high precision. The spin welder HS-OSW is targeted for manufacturers of small-diameter components (down to 0.125 in/ 0.08 mm) such as fittings, tubing, and fuel lines for the medical, automotive, and industrial markets.
The HS-OSW is a servo-driven spin welder that is capable of orienting part halves relative to each other with a positioning accuracy of +/- 1.0 deg. Exact start (home) and stop (final orientation) points can be programmed and precisely controlled. It runs up to 7,000 rpm, unlike standard servo models which operate at up to 4,000 rpm. It features an innovative dual-speed proportional valve for pneumatic pressure control, allowing the user to program individual settings for initial part approach speed, contact pressure, weld pressure, and cooling pressure in pass code protected memory. This capability reduces cycle time by 20% compared to standard single-pressure, servo models and also improves repeatability.
A six-inch color touchscreen serves as an effective user interface with an integral programmable operator control station which simplifies parameter input and allows a range of measurements to be displayed. These include rpm, weld mode, weld distances, hold time, pressure, resettable parts counter, and total machine cycle counter. A modular design allows adaptability to a variety of production configurations. Controller height can be repositioned or removed from the press and relocated to a user preferred position. Zero-force cycle activation switches reduce operator fatigue compared to mechanical start switches.
