Definition - What does Injection Pressure mean?
Injection Pressure is the pressure applied on the injection screw when a material is being injected into the mold. It is useful for the treatment of the rock matrix. Injection Pressure enables test fluids to be injected into rock formations without causing breakdowns or fractures. However, it requires surface pump pressure to achieve injection. The hydrostatic pressure of the liquid also affects the pressure injection as it contributes to the downhole pressure value. Injection Pressure is demonstrated in terms of PSI.
Petropedia explains Injection Pressure
Injection Pressure is used in injection molding machines. As the plastic materials that are used in the devices are quite stiff, they need injection pressure to fill the mold. It is one of the essential factors that are used to determine the properties of molded parts in the machine. The pressure should be high so that it can fill the molten polymer into the mold completely. It is further categorized into two parts, i.e., fill pressure and hold pressure. Fill pressure is stronger as compared to hold pressure.
