Backpressure is the pressure applied to the molten material during the screw retraction (plasticizing) stage of the injection molding process. It is the pressure built up in the barrel and is achieved by different hydraulic setpoints depending on the intensification ratio.

Air trap is a phenomenon in injection molding process where air trapped in the mold cavity prevents molten plastic from filling the cavity, resulting in defects such as short shots, burns.

In general, the ejection distance of lifts in injection molds is not long, and it is easy to break. Injection molds that can achieve automated production have a longer ejection distance than semi-automatic molds.

Injection mold exhaust system is an important part of injection mold design, why do injection mold need exhaust systems?

3D scanning is the process of using a 3D scanner to capture the three-dimensional data of an existing object.

Incomplete masterbatch dissolution in injection molding can cause uneven surface color of the product, which is not allowed for products with appearance requirements. So, what are the reasons for incomplete dissolution?

A drill machine is a machine tool used to create holes in a workpiece. It is an essential tool in the injection mold manufacturing process, where drilling is a necessary operation.

Grinding machines are commonly used in injection mold processing to perform precision machining on mold surfaces. The working principle of a grinding machine is to use a high-speed rotating grinding wheel to rub against the workpiece to remove material from the workpiece surface, thereby achieving the required flatness, smoothness, and dimensional accuracy.

Milling machines have a wide range of applications, mainly in the fields of mechanical manufacturing, mold manufacturing, and automobile manufacturing.

EMD, or electrical discharge machining, is a metalworking process that uses electric sparks to erode material away. It consists of a worktable, electrode, power supply, and control system.
