Computer Aided Curing Unit
Using of Computer in control of curing cycle is most effective method of standardizing the quality of composite products. Because it eliminates the negative effects of labour.
CACU has an electronic board that connected to a PC. The board allows user to set several time- temperature diagrams. Than PC records the time-temperature diagram of curing cycle, during the process.
 CACU 35 7200W
Plate Dim.: 35 cm x 55 cm
Stroke: 35 cm
Heating power: 2x3600 W
CACU Controls;
Heating: The mold is heated up by two plate.
Cooling: The mold which has cooling ducts, is cooled by water flow.
Pressure: A hydrolic unit is used to press the mold.
Vacuum: A vacuum pump is used to remove air gap from the mold.
Time: It’s possible to change the heat up rate, curing time, and cooling rate for several materials.
There is a process layout that shows temperature, pressure and vacuum graphics below.

Compression Moulding
As with vacuum bag and autoclave moulding the prepreg cloth is laid into the mould, or pre-formed into a separate, shaped charge to facilitate rapid loading in a hot tool. The moulds/tools are usually machined or cast metal, and are produced as male and female matched halves, the space between them defining the shape and wall thickness of the component being made.
Pressure Bag Moulding
This method is an extention of vacuum bag and autoclave moulding and uses a rubber bag, often silicone, on top of the layup. Heat for curing and pressure for consolidation can be supplied by a compressed hot gas or fluid. The process may also be vacuum assisted. This method is often applied to simple sections such as tubes.
