The Brazilian equipment manufacturer Fibermaq has created a system called Assisted Infusion to reduce resin loss and prevent the occurrence of fires
The system is designed to overcome the need for pre-preparation of the whole amount of resin to be injected into the mould. In the event of any unforeseen circumstances – power loss, vacuum leak, compressor failure or obstruction of injection channels, for example – the manufacturer is forced to dispose hundreds of pounds of the product. In addition to the financial loss, such disposal can cause fires to to excess exotherm.
According to José Batista de Andrade, The company’s CEO, it is a relatively simple solution. “We developed a pneumatic doser of resin and peroxide that controls the amount of material prepared. When using it, the processor determines the exact pace desired, instead of being forced to finish the entire resin at once”, he describes. Thus, even if difficulties occur during the infusion, the volume lost does not exceed 3 kg. “A very small amount, much easier and safer to dispose”.
Besides the doser, a special tank is part of the Assisted Infusion system, in which temperature and level are monitored by sensors. “It is a tool that helps the manufacturer to have even more control over its process”, said Batista.
Intertronics has compiled a guidance note on how to specify a dispensing robot.
