Also covered will be the ways in which advancements in injection molding have allowed manufacturers to operate with greater flexibility and dependability than was previously possible.



ABS Injection Molding has been around since the latter half of the nineteenth century, according to historical records. As a result of the invention of injection molding in the 1870s, more malleable forms were quickly developed as a result of this development. Manufacturers were also able to achieve a higher level of customization and accuracy as a result of improved plastics and manufacturing processes, allowing them to produce parts and pieces to exacting specifications for a variety of applications, including medical devices.



PIM forming molds have traditionally been made of two plates that were joined together: one plate that contained a cavity and another plate that contained a core. This is still the case today. With the use of computer-aided manufacturing (CAM) techniques, modern molds can be significantly more complex than their two-plate predecessors, containing multiple parts and sections rather than a single part and section. In addition to the mold cavity and core (as previously mentioned), modern molding techniques enable greater complexity in the finished product by detailing and designing molds to exacting specifications.

James Watson Hendry, an American inventor, was responsible for changing the course of history for the entire manufacturing industry when he invented the world's first screw injection machine in 1946. It was possible to exert significantly greater control over the speed of plastics injection using the screw injection molding machine, resulting in significantly higher overall quality of finished pieces. Hendry's machine also allowed for the pre-injection mixing of materials, which allowed for the mixing of colored, recycled, and virgin plastics, among other things, in the same injection chamber.
