The study of injection molding functions or states gradually declines with the expansion of the use time. There are some precursory information will be shown when injection molding machines errors occurred. These precursory information is also called potential fault, which identifies physical parameters indicating that a functional failure is about to occur, functional faults indicate that the injection molding machine has lost the predetermined performance standards. The change of the injection molding machine errors rate with time is often called the tub curve. The failure rate of the injection molding machine is roughly divided into three phases: early fault, occasional fault period and lossy fault period. 1. Early fault period The injection molding machine is in an early failure period, and the failure rate is high, but the

The first implant material is called the substrate or base material, and the second implant material is called the over molding material. 1. Various two-shot injection molding technologies During the overmolding process, the cover material is injected over, under, around, or into the substrate to form a complete part. This process can be done by multiple injection molding or insert injection molding. A commonly used covering material is elastic resin. Multi-injection: Multi-injection is a good method of medical device processing if the construction of the covering material allows it.

The keys described in this section are used for numerical and text input to the data entry function on a plastic injection moulding maker. Important: In order to avoid any loss of data and/or settings make sure you have saved the current mold set again before loading a new mold. If you fail to do so any settings changes you may have made will be lost. When you turn off the controller/machine the current settings will be saved as the working mold set. Nevertheless, you need to save the mold set again before loading any new mold set since any changes you made

Like the screw, the barrel also works under high pressure, high temperature, severe wear and certain corrosion conditions. During the extrusion process, the barrel also has the function of transferring heat to the material or transferring heat away from the material. A heating and cooling system is also installed on the barrel, and the machine head is installed. In addition, the feeding port should be opened on the barrel. The geometry of the feeding port and the selection of its position have a great influence on the feeding performance. The smoothness of the inner surface of the barrel, the grooves on the inner wall of the feeding section, etc., have a great impact on the extrusion
