Ultra fast compound heater - UFC

In the middle of the 1990s, a new concept was born for the processing of EPOXY-Resins. Up to that time, Epoxy-resin was typically injected from a pressure-pot with a temperature of approx. 30 – 40°C into the mould (not valid for 2-component dosing machines). This fairly low temperature leads to a relatively long cycle-time that limited the production-capacity. Thus the idea was born to develop a system to increase the injection temperature even before injection into the mould. With this idea, Vogel designed and built “Ultra fast compound heater” (UFC) – units with the capacity to heat up the reactive resin “onthe- fly” prior to injection.


The system is equipped with a regular pressure pot, and an inline-built heat exchanger that is capable to heat and cool the resin on the way to the mould. It is important to mention the cooling-capability to make sure that the temperature in the piping to the mould stays at a low temperature after complete injection, thus avoiding any curing of the reactive resin ahead of the mould. The equipment comes as a completely independent unit that comprises heating/cooling capabilities besides the necessary logic and valves, including a separate PLC to run down the process automatically.


Advantages in short:

Increase of temperature for injection by about 30° – 40°C. Shortening cycle-time by up to 50%. Applicable especially to large filling volumes and parts that have extended wall thicknesses. The process reduces the exothermic reaction during gelation. Thus a more uniform gelation is achieved. Less risk of cracks and tensions inside mouldings.


■ Productivity increased by up to 40%

■ Space-saving alternative when production expansion is planned
