Plastic Injection Molding

Our Plastic Molding Business
Doyle Shamrock Industries has been in the business of plastic injection molding since 1975. The business began as a one man operation, and it quickly grew after a few highly skilled plastic mold makers were hired. Today, our plastics facility encompasses 200,000 square feet of space to fulfill all of your injection molding requirements. We are an ISO/TS 16949:2009 certified molder, and our quality department is equipped to meet your most demanding requirements. We have two plastic injection manufacturing locations plus an off-site warehouse and distribution facility.

Our Plastic Injection Molding Machines
In October 2017, we added two more high capacity plastic injection molding presses to keep pace with customer demand for plastic molded products. Our inventory of plastics machinery now includes 30 injection molding presses ranging in size from 55 tons to 2000 tons to accommodate molds of a wide range of sizes. Whether your molding job is small or large, we have the ability to supply plastic molded products to buyers throughout the United States and beyond. A complete list of our plastics equipment is displayed below along with the specifications for each molding press. We stock a wide variety of thermoplastic resins for your plastic injection project, and we can provide a molding solution for your molded plastic part.
