Abstract
Injection molding technology has been in development for almost 150 years. Injection
molding is a molding technology that melts the material with the aid of a screw and an
external heating device and then injects it into a mold to form the corresponding product as
the mold cools. At present, many types of materials can be used to mold products by injection
molding.
Many requirements and problems in the processing of different materials have also caurs ed
the birth of many molding processes. At present, injection molding has been applied in many
fields, from daily necessities that are closely related to our lives to parts and components in
the aerospace field. At present, injection molding still faces the challenges of processing new
materials, and the continuous improvement of the existing equipment technology is required
for the continuous development of injection molding.
Injection molding is the fabrication process which is the most widely used for polymeric. This
paper describes Injection molding process in detail along with its process parameters and their
effects on the molding component. Runner system is playing a significant role in the quality
of the molded part.
Every injection molding method works when a plastic substance flows from the sprue of the
runner system, through a gate into the mould cavity. Runner system is of two types, Hot
runner and cold runner system, both having some advantages and disadvantages of each. It
has been observed that although hot runner gives better quality of the product, many of the
industries use cold runner due to the high cost and complexity of the design.
