bdtronic, a global manufacturer of dispensing machines and systems that process polyurethane, epoxy, silicone and liquid resins, has developed what it claims is the world’s largest and fastest automotive motor impregnation machine. The B8300 impregnator is designed to speed up the motor production process – its main function is to fill electric motor stators with a solid gel resin. It has a cycle time of 45 seconds per stator and a 500,000-part annual capacity. It’s no surprise that the company recently acquired impregnation component specialist and former supplier Reatina Costruzioni Mecchaniche (RCM).
The impregnation process begins when a robot grasps a rotor or stator and slowly rotates it as resin is trickled in. The process, known as gelling, creates a solid gel around the object. bdtronic’s goal is to provide low resin consumption, thorough fillings, and a carefully monitored resin distribution in motor windings.
“We have a lot of experience in dispensing and impregnation technology,” says bdtronic Managing Director Patrick Vandenrhijn. “This connection is unique in the market. This has enabled us to build a plant that ensures both high quality and high production volumes.”
