Manufacturer of fiberglass with the method of RTM injection.
Manufacturer of fiberglass with the method of RTM injection (Resin Transfer Moulding) is a manufacturing technology of the composite material by the method of injection resins in closed form. RTM method allows you to make more technologically advanced products with high physical-mechanical properties.
Description:
Manufacturer of fiberglass with the method of RTM injection (Resin Transfer Moulding) is a manufacturing technology of the composite material by the method of injection resins in closed form. RTM method allows you to make more technologically advanced products with high physical-mechanical properties, such as the elements of the UAV, part sports car, Aviacompany etc.
The method requires the use of special equipment, consisting of a matrix and punch. Between the matrix and the punch is laid dry, pre-cut material (carbon, fiberglass, special glass Mat or other reinforcing material). Then, with the help of a special pump in a closed form under pressure is injected mixture of resin — hardener. After curing, the finished product is removed from the mold and subjected to machining if required.
Molds can be made from steel, aluminum or composite material. Used special fabric (glass-, carbon -, etc.), polymeric foam and honeycomb fillers, including various combinations of structures type “sandwich”, it is possible to use mortgage elements.
The kind of method, RTM-injection, is a manufacturer of fiberglass RTM Light method. Light RTM method is characterized in that the pressure stamp and punch is performed using vacuum, and the punch is a lightweight positive impression matrix. A vacuum is also created in the working cavity shape, which allows to achieve optimum impregnation of the reinforcing material.
Advantages:
Manufacturer of fiberglass injection has significant advantages over the technology of manufacturing fiberglass hand-formed or technology of manufacturing fiberglass coating:
– both sides of the fiberglass products have a smooth surface with the pre-set relief
– in the manufacture of fiberglass injection minimized waste of materials,
-accurate dimensions and excellent reproduction of fiberglass products,
– high content of glass filler in the manufacture of fiberglass (up to 65% of the volume of the product),
– no air inclusions in the product of the fiberglass,
– reduction of time of manufacturing the product in GRP is 5 to 20 times,
– increase the rate of turnover snap
– reducing the number of workers, reduction of qualification requirements in the manufacture of fiberglass
– sharp reduction of discharge of harmful substances into the atmosphere, improve the working environment, reduce the cost of ventilation in the manufacture of fiberglass
– the possibility of introducing fillers of other types (cost reduction fiberglass products, increased fire resistant properties, reducing the degree of shrinkage of polyester resin during curing).
