Injection Molding Control System Components

Injection Molding Control System Components

Control systems for injection molding machines are designed to provide quality control and to optimize performance. Typically, the injection molding control system includes a host device, a control method, actuators, and a substrate. The injection molding control system also includes software that is programmed for performing tests on the various models of molds. In some cases, a control method is provided that controls the process of material feeding into the mold, such as a timer or an auto-counter.

In different embodiments, a single control of the injection molding control system acts as both the tuning device and the temperature controller. In other embodiment, the tuner is separate from the other components of the machine for the purpose of normalizing and/or autotuning the temperature of the PID control. Some machines may include one or more of these techniques. A variety of control methods are included in the control systems for injection molding machines. Examples of such methods include ultrasonic welding, magnetic induction, rotary screw, laser cooling and heating, and imaging.

In some situations injection molding machines may include two or more thermometers. A thermometer measures the internal pressure of a material during the manufacture process. This pressure is typically measured in pounds per square inch (LPI). Other pressure measurements may be necessary, depending upon the nature of the product being manufactured. These measurements are typically measured in gallons per minute (GPM).

There are two types of cycles in injection molding machines. The first is the cycle type and the second is the cycle step. In the step cycle, the injection molding machines continue operating as long as desired, allowing the material to cool. When the material reaches the correct temperature, it is removed from the injection molding machines and gravity feeds the cooled product into the next stage of production.

The IDP is an important part of many injection molding machines. It performs a number of functions, including an initiation position and a repositioning position. The PID control determines the correct position, which in turn controls the other parameters in the injection molding process. This information is crucial to safety and the success of the invention.

Injection molding machines 10a and 10b use a variety of different schematics. Schematic views can be used to design the entire mold infrastructure at the onset of operation. However, manual changes, additions or subtractions can be made after the product has been manufactured. In order to make the necessary changes, manual tracing of instructions must be performed by someone who has knowledge of both the IDP and the other components used in the manufacturing process. It is not uncommon for injection molding machines to require constant repair and adjustment.
