The Overtec system is a low-pressure moulding process that uses thermoplastic moulding resin to achieve high quality sealing and protection of components, faster than 2 component potting resins and far lower capital cost than injection moulding.
A process innovation positioned between casting and injection moulding technologies, the Overtec system utilises a low injection pressure that means fragile or delicate components can be encapsulated and protected with no risk of damage. The Overtec 5 FR resin sticks simply need to be loaded into the Overtec 820-15 glue gun and allowed to reach operating temperature before use, resulting in a simple and clean process with fast cycle times.
Overtec 5 FR has excellent chemical resistance and thermal durability, with an upper heat resistance of 135°C (286ºF), and a lower temperature flexibility of -35°C (30ºF). Overtec 5 FR has good chemical and water resistance, in addition to excellent electrical resistance and dialectric strength. It is an excellent fire retardant, rated to UL 94 V0 flammability. Overtec 5 FR also provides a higher output than many casting applications, reducing cycle times and labour costs.
