June 17, 2019

Roncelli Plastics is a precision plastics manufacturer continually improving their capabilities to exceed their customers demand. This 50-year fabricator’s portfolio of CNC multi axis machining, Rapid Production Manufacturing, 3D Printing, die cutting, stamping, forming, engineering and design support provides best in class solutions of near net non-metallic custom parts. We’re pleased to say, they’ve now added two of our J180ADS-300U Injection Molding Machines. This expansion will gain additional opportunities to their business for years to come.

When we inquired with Roncelli Plastics’ GM of Operations, Tom Marquez on how this will benefit the company, he explained “This [Injection Molding Machine} offers another commodity that Roncelli Plastics can provide in addition to our CNC machining and 3D printing. It makes Roncelli Plastics a “one stop shop”. We can now offer cost efficient components in high production volumes. More versatility on features that would require multi axis machining. This gives the customer super flexibility in design and material. Offers high efficiency in mass production, significant strength enhancement and reduced waste”.

We had the opportunity to visit their facility post installation of the machines and were impressed with their streamlined operations, cleanliness, digital work centers and knowledgeable staff. They’ve completed testing samples and are in production of their first aerospace molded parts.

Roncelli Plastics’ works with small start-up to Fortune 100 organizations in the aerospace, semiconductor, medical / life science, oil and gas and renewable energy markets.
