At MANAR, our plastic injection molding services set the industry standard for quality and performance. We operate five production facilities, four in the United States and one offshore, that house a large fleet of presses in the 50-ton to 2,300-ton range, giving us enormous capacity and flexibility. Our technical capabilities enable us to produce everything from single-shot designs to complex parts that require inventive tooling, automation, and unique finishes. We have extensive experience molding commodity-type, engineering-grade, and the newest high-performance plastics with high heat resistance and other special properties.

We leverage advanced molding techniques to deliver parts on time and at competitive prices. Our injection molding capabilities include overmolding, where we use two or more resins to mold a single, integrated component and insert molding, where we embed metal inserts to create an assembled part right in the mold. For more complex pieces, we use scientific molding methodology to design the part and tooling and determine key process parameters such as melt temperature, flow rate, mold temperature, fill pressure, etc. This enables us to establish and execute a process that generates the most repeatable results while optimizing the accuracy and mechanical characteristics of the molded part.

Along with general-purpose resins like polyethylene, polypropylene, polystyrene, and PVC, some examples of resins we are accustomed to molding include thermally resistant Ultem^®, medical-grade Radel®, high-strength and transparent UDEL^®, and high-performance engineering thermoplastics like PEEK^®.

In our injection molding area, we can implement dedicated automation cells and robotics for contract manufacturing programs. We provide ISO 9001 and ISO 13485 certified quality assurance and offer a full range of additional services. Markets served include medical, consumer, industrial, aerospace, automotive, lawn & garden, and more. To learn more about our injection molding operations or request a quote, contact us directly.
