With more than 50 years of molding experience, Mars Plastics ranks among the largest injection molders on the East Coast. Our business is family-owned, and we have knowledge spanning generations. Every prospect is welcome, whether they are small inventors or major corporations. We have assisted in launching many small ideas into industry-leading ventures. The Mars team trained large companies on how to relocate their unprofitable businesses to our facility from overseas, enabling them to achieve significant gains and regain profitability. We possess a diverse collection of 40 injection molding machines (36 located in Providence and 4 at our Cranston, R.I. facility), with sizes varying from 12 tons to 1400 tons and shot capacities reaching as high as 160 ounces.
