I. Introduction

The manufacturing industry in the USA has undergone numerous changes since the COVID-19 pandemic struck in 2020. This is due to increasing demand for plastic products especially in the medical industry. Competition from countries like China, Japan and India who have mass production industries that rely on cheap labor has forced manufacturers in America to find alternative methods of production that are cost effective and provide quality products. One of these methods is plastic injection molding. This is a manufacturing process where molten plastic is forced or ‘injected’ into a mold and allowed to cool, resulting in a finished product.Injection molding can be used with various materials, including plastics, elastomers, metals and composite materials. Plastic mold injection is widely used across industries like medical, aerospace, automotive and manufacturing for mass production of plastic components. Manufacturers prefer using this method because of its high reliability and repeatability because they can produce the same quality and standard of products using the same molds. Plastic injection molding also promotes sustainability because most companies use recycled plastic materials to create new components. In this article, we have highlighted the top 10 providers of plastic injection molding in the USA.
