The client needed to clean steel moulds intended for plastic injection. In addition, only one operator could be assigned to supervise the process. As these are moulds of great weight and size, the client requested customized measures for the loading rack and ruled out installing an elevator, since it had its own crane bridge.
The cleaning of the moulds requires superior finishes to minimize the percentage of product rejection. Therefore, the challenge was to design an efficient solution that offered maximum power with minimum energy consumption. We also perform laboratory tests on the original mould so that the client could check the effectiveness of our chemical solution.
A customized three-stage installation was chosen: ultrasound + rinse + anti-corrosion protection drying process, digitally controlled by a touch screen. This installation met the customer's requirements, allowing to increase and improve the quality of production. It was amortized in a few months.
Stage 1: BRIO Ultrasonic cleaning
This first bath removes the remains of plastic on the entire surface of the mould, which in this case is steel. The ultrasound affects the water in the tank and causes a microscopic hammering that removes the dirt stuck on the surface and in the cavities of the piece. To speed up the process, the machine heats the water in a range between 65 and 80ºC. In addition, to gain effectiveness, a specific BRCLEAN alkaline detergent is provided for the application.
Stage 3: Anti-corrosion protection drying process
This process displaces any particles that may remain in the mould, also providing a thin corrosion protection film.
