Our History

RSP, Inc. began its journey as Ryan Screen Printing, Inc. Founded by brothers Robert and John Ryan in the basement of their parents’ house, the company experienced early success. Recognizing the potential, their father, Norbert Ryan, joined the business and played a pivotal role in its expansion, spearheading investments in state-of-the-art equipment.

From humble beginnings, our initial products included real estate signs and advertising banners for Schlitz Brewing. As our reputation for quality craftsmanship grew, we had the opportunity to collaborate with esteemed local businesses including Harley-Davidson, Rockwell Automation, Miller Brewing and Johnson Controls.

Over the years, RSP has evolved into a global, full-service contract manufacturer, proudly providing our customers with comprehensive turnkey solutions for all their plastics molding, manufacturing packaging and logistics needs. Our commitment to excellence, innovation and customer satisfaction remains unwavering.

We pride ourselves on providing the exceptional customer service and efficient solutions of a family-owned business like ours while cost effectively offering a wide variety of products and services at scale.

RSP, Inc. is also a global company, with manufacturing hubs in the US and China. We have extensive international experience shipping to more than 40 countries including the US, China, Canada, Australia, and the UK. We also have expertise across a range of industries.

RSP: Milwaukee WI, USA Headquarters

In 2005, RSP ownership and operations were passed to the next generation, Mike Ryan and Paul Ryan. This is a business built on family values, integrity and trust. The new owners broadened the company’s offerings to include plastic molding, rubber molding, and electronics. As these new products became a substantial part of the business, the company name was officially changed to RSP, Inc. in 2009 to reflect the variety of offerings while at the same time providing a tie to the company’s history.

Our Commitment to Environmental Sustainability in Manufacturing

RSP is committed to sustainable manufacturing practices that reduce environmental impact. We have policies in place to minimize waste, energy use, and resource consumption.

We have implemented the following best practices:

  • Investment in energy-efficient electric plastic molding machines
  • Use of flexible manufacturing cells to reduce handling and energy consumption
  • Installation of a new filtration system to reduce particulate matter
  • Use of returnable packaging pallets and totes when possible

RSP is also leading the way in studying and testing evolving more environmentally sustainable plastic options including:

  • Recycled ocean plastic in manufacturing. RSP offers Oceanworks® Guaranteed products utilizing a verified supply chain from oceans, beaches, rivers, and shores.
  • Use of organic additives that activate in the presence of specific microbes and enzymes found in landfills to help break down plastic when it reaches its end-of-life destination.
  • Blended bioplastics include hemp, rice, and other fibers to meet the demand for sustainable plastics.

RSP works with our clients on sustainability to help them develop the optimal product for their market and needs.
