Description
The APP Automated Gas Assisted Injection Molding System (AGAIMS) provides precise pressure generation and control from atmospheric pressure to 3,000 PSI (pneumatic system). The AGAIMS assists the injection molding process by inputting the desired amount of pressure into the mold at the optimal time, thereby ensuring that the part being molded forms appropriately.
Software
The AGAIMS is completely microprocessor controlled and fully automated -- the system allows the user to define a desired pressure profile that can be simulated. Easy-to-use AGAIMS software is compatible with Windows '98 and higher. Throughout the pressure control process, this software provides useful reports and data, including a real-time graphical display of the desired versus actual pressure profile. Upon termination of the pressurization process, data such as the actual and desired pressure profiles and the percent error can be downloaded for further analysis. Advanced Pressure Products also has the capability to customize the software to produce reports and data required for a specific application.
Applications
The Automated Gas Assisted Injection Molding System can be used to enhance the injection molding process in the plastics industry. By automating and accurately controlling the gas injection process, the AGAIMS helps the plastics industry to minimize materials costs without sacrificing strength. The AGAIMS helps to ensure that the part being molded takes the desired form with little operator effort.

Hardware: Pneumatic System (Applications up to 3,000 PSI)
The Automated Gas Assisted Injection Molding System - Pneumatic System comprises a booster, regulator, reservoir, pressure transducer, flow meter, motorized valves, and a pressure controller. The DC motor driven piston pressure generator produces up to 3000 PSI output. A highly accurate pressure transducer monitors system pressure and provides feedback. The AGAIMS - Pneumatic System contains motorized metering valves for pressure control and venting, and solenoid valves for pressure control, inlet selection, and venting.
The high degree of pressure control offered by the AGAIMS - Pneumatic System is accomplished through a unique arrangement of needle valves, which regulate the flow of injection gas. Initially, the maximum flow of gas that can pass through the lines, mold, and nozzle orifice without causing a choked condition is determined; the needle valves then adjust automatically to a series of settings. Essentially, the needle valves are sized to provide maximum control at all times. The number of needle valves employed is dependent on the percentage of resolution of control desired - higher resolution requires more needle valves.
The solenoid valves can be activated in different combinations to control the gas flow from 0.40 to 99.6% of maximum flow rate. To follow any given pressure target curve, the program will automatically activate a different combination of the solenoid valves.
The AGAIMS is available only as a pneumatic system (hydraulic system not available).
