HotMelt: Connections safely protected

Parts and components that matter to you are best protected with the HotMelt moulding process by rmw Kabelsysteme GmbH. This is produced quickly, safely, reliably and permanently.

Product safety – fits like a glove

Protect your important connections: With HotMelt, rmw Kabelsysteme GmbH offers you a high-quality low-pressure spraying process to reliably protect your components from external influences.

The socketing of a moulded connector not only serves as a housing, it also protects against unauthorised access and acts as an effective strain relief.

The compound used by rmw is compatible with electronic components and circuit boards of all kinds, without affecting any functionality. The required moulds are designed by rmw itself and manufactured using machining. Once again, rmw is your trusted provider, producing exclusively tailor-made service to meet your requirements.

How rmw HotMelt-protects your components

In the HotMelt process, thermoplastic high-performance polyamides are heated, melted and then injected under pressure into a mould. After a short cooling process, your finished component is removed.

Maximum fire safety: HotMelt at rmw

The classification according to UL94 ("Tests for Flammability of Plastic Materials for Parts in Devices and Appliances") is significant, especially for electronic components. The highest classification "V-0" of the HotMelt material used by rmw means, after a standardised test procedure, the generated flame extinguishes within a maximum of 10 seconds. Afterwards, the material must not glow for more than 30 seconds.
