RSP: International Contract Manufacturer - Manufacturing in China

What is a Contract Manufacturer?

A contract manufacturer allows you to outsource some or all of your production and assembly so you can focus on the other core aspects of your business. While this is a simple definition, RSP understands that being a contract manufacturer is anything but simple. The relationship is much more than a contract; it is a partnership based on trust.

Outsourcing for Cost Reduction

Outsourcing your project with a contract manufacturer, such as RSP, allows us to control manufacturing costs to benefit your business. We use both Chinese and U.S. facilities to ensure costs are kept at a minimum for all products we manufacture.

From Start to Finish, We are Here to Help

At RSP we are much more than clever slogans and cute words. When we offer Turnkey Manufacturing services, it means that from prototyping, to product design, to packaging and shipping, we will be with you every step of the way. We don’t expect you to take our word for it though. As entrepreneurs, inventors and forward-thinkers we know that what really matters are the results, and in our case they speak for themselves.

In 2017, RSP was contacted by Bevstir Innovations to discuss the manufacturing of their newly patented wine aerating product, the vSpin. Using proprietary magnet technology, the vSpin would revolutionize the decanting process, slashing the time from 20-30 minutes to under 5. Our clients, veterans of the restaurant industry, knew they had a successful product concept but now needed to take their vision and transform it into a realized product. Working with only very basic prototypes, RSP stepped up to the challenge.

Bevstir was assigned their very own dedicated project-launch team made up of engineering and product development staff from our U.S. and China offices. Thus, we were able to offer virtually 24-hour accessibility. Packaging needs, material specs, customer objectives and price targets were all discussed in minute detail to offer the most comprehensive service. Just 8 months after project launch, RSP was able to take a 2-dimensional concept and offer a production ready unit. Bevstir’s success didn't’ end there...vSpin recently won the German Design Council’s 2018 Design Award!

This is what it means to manufacture dreams into reality with RSP. To learn more about our work with Bevstir, check out our case study.

  • Do all facilities working on my project adhere to fair labor practices?
  • Is your company financially secure? How long have you been operating?
  • Do you have experience manufacturing [insert your product here]?

Let Us Do the Sourcing

Many companies find themselves exploring foreign markets for additional parts, components and capabilities to complete their products. Unfortunately, these searches can often result in poor quality, project delays, miscommunication and ultimately increased costs. With over a decade of experience working directly with offshore manufacturers, we can navigate the Chinese market for you.
