Engel/Cannon tie-up to advance Clearmelt PU technology

Automotive pilot project launched to address ELV plastic waste

Austrian injection moulding machinery maker Engel and Cannon, provider of mixing and metering technology for reactive processes such as polyurethane (PU) or RTM, have entered a strategic partnership. The aim of this cooperation is to further develop technologies for PU flooding and enable industrial applications with even higher quality and efficiency, the companies say.

The demand for high-quality PU-coated components is steadily increasing. Engel refers to this technology as clearmelt and has decades of experience with it, as well as a multitude of customers and references. With the clearmelt process, components are coated with PU directly in the machine after the injection moulding process.

Now, Engel adds it is strengthening its position through the partnership with Cannon to combine long-standing expertise and leverages synergies to continue offering customers forward-looking solutions.

Furthermore, Engel says customers benefit from clearmelt with a coordinated technology that enables the economical integration of PU into industrial manufacturing processes.

The clearmelt technology, which coats thermoplastic components with a durable PU surface, will be further developed and optimised through Cannon’s know-how in this field.

A prime example of this collaboration is the world's largest injection moulding cell with a PU system for clearmelt, which has been commissioned at the Engel technical centre in Sankt Valentin. There, customers can conduct practical tests with various PU colour variants.

The combination of the world's largest injection moulding machine in a technical centre, the Engel duo 5500 combi M, and the precise metering and mixing technology from Cannon ensures maximum process stability and flexibility, the firms claim.

The PU system from Cannon is integrated into the CC300 machine control system from Engel to not only speed up the production chain but also improve the overall quality of the final products, it adds.

The companies say that customers benefit from strong after-sales and application support, which, with extensive know-how, also assists in integrating this technology into existing production processes.

Plus, the companies can offer optimal production cells for combining injection moulding and polyurethane processing.
