Fibermaq will launch an injection machine for the RTM process, at Plastech Brasil, a technology that is widely used by moulders of composite parts consumed by the automotive industry.
The RTM Evolution Electronic, as it was named, includes a PLC control system that allows the storage of different injection programs. “It also makes the job much more accurate. In both the pneumatic and electronic versions, the volume of material injected will always be that previously defined. In the pneumatic version, the dosing is given by the number of strokes, that is, multiples of 100 ml. In the electronic model, in turn, the volume to be dosed is more flexible,” says Christian de Andrade, Director of Fibermaq.
With a design that favours mobility – many manufacturers usually take the injection machines to the moulds, rather than the opposite, the RTM Evolution Electronic features a new pressure gauge configuration, which further facilitates the control of the operation, and a display to indicate the passage of peroxide. “Another positive aspect is the more simplified system for hose fitting. And to increase the operator’s safety, we closed all areas where there are moving components.”
At Plastech Brasil, Fibermaq says it will also introduce a new gelcoat machine model, with capacity of 4 kg/min, it is ideal for the manufacture of small parts. The equipment was developed at the request of customers who want to manufacture very small parts for the application of gelcoat through the traditional airless system, a technology that, regardless of the machine supplier, generates waste in applications of this kind.
“This occurs not only because of the higher pumping pressure, but also because of the excess material applied to the part,” says Edmundo Pinto, representative of the technical department of the polyester equipment line at Fibermaq.
