About Us

Mayfield Plastics has played a prominent manufacturing role in Central Massachusetts for almost a half-century. In 1970 the former parent company of Mayfield Plastics, S.Ralph Cross and Sons, decided to transform its pattern making business. Founded in 1917 by S. Ralph Cross, his sons, Stanley and Gordon Cross, made a strategic decision to capitalize on their core competency, mold making, by coupling it with the manufacturing of custom made plastic parts using the emerging plastic forming process of Thermoforming.

The company grew and prospered through from 1970 to 2000, when the Cross family decided to move the company to a new, 60,000 square foot facility on a beautiful parcel of land in Sutton, MA. Ron Cross, Gordon’s son became the president and opened the new facility in 2006.

Mayfield Plastics’ success stems in great part from its basic values – hard work, devotion to quality and most of all, Integrity. The Cross family believes that any enterprise, personal or professional, is rooted in its ability to keep its promises, produce quality products, and delight its customers. It is one of few companies to assert a value pledge to its customer. (You can read more about this on the Value Pledge tab.)

That tradition continues today while the company increasingly serves the custom plastic parts needs of a variety of industries including aerospace, medical device manufacturers, transportation and electronic companies.

Mayfield Plastics is registered with the International Organization for Standardization (ISO), which certifies that the company pays strict adherence to the manufacturing processes it promises its customers.

Located in the heart of the Blackstone Valley Corridor of Massachusetts, Mayfield Plastics is an active advocate for encouraging young people to enter manufacturing as a career. Working with the Manufacturing Advancement Center Workforce Innovation Collaborative, the Manufacturing Extension Partnership, and the Mass Development Corporation, Mayfield Plastics has assumed a leadership role in advancing careers in manufacturing today.
