Composite Integration's injection processor enables high levels of control

Composite Integration (Saltash, U.K.) has developed a new meter-mixing injection and infusion machine, the Ciject Five. Designed to complement its existing range of infusion processors, the Ciject Five is tailored for large-scale operations.

A key requirement of large-scale resin infusions, Composite Integration says, is ensuring a consistent mix ratio throughout the process. The Ciject Five is reportedly capable of monitoring flow rate of each component, verifying the mix ratio and adjusting the pump speed as needed. It features In Mold Pressure Sensor (IMPS), which enables operators to achieve a high level of control over the process.

According to Composite Integration, the Ciject Five is designed to replace manual mixing in the infusion process. It automatically pumps and mixes resins and hardeners, maintains the mix ratio and controls the rate of injection based on pressure feedback from the mold. The process can be controlled by either pressure or flow rate without causing over-pressurization.

The Ciject Five is reportedly capable of controlling the infusion pressure to a resolution of 100 millibar (mbar) while continuously infusing. According to Composite Integration, typical infusion pressure is 700 mbar, which leaves a positive pressure on the bag of 300 mbar or 3 tons/meter sq. This level of flow restraint provides the user control of the final volume fraction. For further control, the Ciject Five can monitor up to four in-bag sensor inputs per mixing unit, and more IMPS inputs are available.

In addition, a number of checks can be incorporated into the machine’s software to prepare for the infusion, including checking the temperature and flow rate of incoming material, intermediate bulk containers (IBC) material levels and more. The Ciject Five also includes an onboard flushing system, and the mixing unit does not require resin purging. According to Composite Integration, the system takes three t -four minutes to clean and solvent usage is minimal (up to 1 liter maximum).
