Slide shows you various cleaning techniques to properly clean your plastic injection molding machine molds and tool steels. Using different cleaners and techniques, both while the mold is still in the machine, and when it is removed from the machine, Slide shows you how to effectively clean and protect your mold.

This excerpt gives a definition of plastics (or polymers) and common attributes shared by all plastic materials. It discusses the basic molecular structure of a polymer. This program explains how and why plastics are different and cites several different types of polymers and processing considerations. Understanding Plastics emphasizes material handling, explains regrind, and covers the effects that moisture can have on molded part properties during processing. A.

PMI is a much faster and cost efficient option especially when pouring a mold is not practical. Also, pouring is more of a replication while the injection process is closer to the duplication of interchangeable parts.

Because the injection process is highly automated, as opposed to traditional manual molding, it will probably be a pre-production support position as you, hopefully, train to become a machine operator. Good Luck.

prolly your basic factory job…boring, repetitive, assembly line, piece work… they prolly make the cartons and the stuffing for other companies products….those plastic forms you see holding toys in place in the box..the box and packing cutouts from your cellphone..stuff like that…you may be doing nothing moe than sticking labels on the side of a carton all day every day..
what ever it is they do, will be explained to you in detail at the interview…that’s what they talk about at the interview..and you talk about how you understand what they say and how you can follow simple instructions….
cuz that’s all your job will entail. following simple instructions.
