BR-600 MOLD - Ultrasonic bottle mould cleaner

Injection mold ultrasonic cleaning projects Multistage

7 September, 2022 – Client: One of the largest brewers in the world

Customer's
requirements

The new BR-600 MOLD, with a capacity of 600 litres per tank, has been designed according to the customer's needs in order to ensure high production levels. It has two ultrasonic cleaning tanks with our OPS oil decanting system that allows the cleaning of two mould baskets at the same time. At the end of the cleaning stage, the baskets pass to the rinsing tank and finally to the passivation tank. At the beginning of the installation there is a loading and unloading area with a grill and an inclined deposit to collect the drip.

The main
challenge

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. Like in other mould cleaning projects, we also perform laboratory tests on the original mould so that the client could check the effectiveness of our chemical solution.

BRIO
solution

A customized four-stage installation was chosen: 2 ultrasound cleaning stages + rinse + anti-corrosion protection process.

It also includes the following equipment:
· Safety walkway with anti-slip system.
· Anti-spill tray for the entire installation
· Activated carbon filtering system for the rinsing stage
· Automatic lids
· Hoist with a load capacity of up to 1000 kg for moving the baskets around the plant.
· Control by means of PLC and touch screen.

You should know

Most mold cleaning equipment is custom made, because its design depends on several factors: customer production times, size and material of the parts to be treated, available floor space ... The same problem may require a customized solution, that's why we are specialized in the design, manufacturing and installation of custom projects.

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 2: Rinse

This process eliminates the remains of detergent by rinsing, with a built-in bubble system that facilitates the total release of the chemical. In addition, the tank incorporates a filtering system that removes the remains of soap deposited in the cleaning fluid.

Stage 3: Anti-corrosion protection process

This process displaces any particles that may remain in the mould, also providing a thin corrosion protection film.

Thanks to our sight glass system, the water that accumulates under the product due to density differences can be easily removed by opening the drain valve. When the operator sees through the sight glass that there is no water left, he stops the emptying and that's it.
