How do you support sustainability goals?

From the early stages of our contract manufacturing process, sustainability is a core part of our discussions with the design and innovation teams to make sure we can identify ways to help you lower your environmental impact. We are continuously investing to ensure every aspect of our business operations is helping reduce Rosti’s environmental impact, which is reflected throughout all areas of our contract manufacturing services. We offer sustainable and recyclable material options during the design phase, and use energy-efficient equipment. By adopting automated and lights-out production, we are able to move away from traditional manufacturing methods, improving efficiency in material use and reducing waste. When we plan the logistics and delivery of a finished product, packaging is an essential part of transporting high-quality goods. Our Contract Manufacturing team helps customers choose lightweight, returnable, or recyclable packaging to minimize waste and emissions while maintaining quality standards.

What is Contract Manufacturing

Contract manufacturing occurs when a company partners with a specialized manufacturer to produce specific components or products for a determined period of time. Think of it as outsourcing production to experts who can deliver exactly what you need, exactly when you need it. In a typical arrangement, a contract manufacturer produces parts, components, or even complete products according to the client’s specifications. These items are then used by the client in their own manufacturing process or included in their final products. Many contract manufacturers operate as third-party specialists, either focusing entirely on contract work or supplying products to several companies.

Rely on Rosti’s Expertise and Analytics

We have a skilled and highly competent team of product designers and engineers, who are capable of developing innovative ideas and optimizing your product design.

Supported by customized software solutions that bring your ideas to life.

Rosti Expert Analytical Systems is a suite of tools for component design and tool optimization. A customized version of Autodesk Mouldflow Insight and Moludex simulates production and troubleshoots problems before manufacturing begins. The goals of this approach are to streamline project management, reduce costs, and avoid the risks you might otherwise encounter when working with new materials, tools, and processes.

The Value of Prototyping

As total solution providers, we understand the value of quick, accurate prototyping, so we have two different approaches that we apply according to your project’s requirements.

We often work with a select group of specialized suppliers to provide a fast and cost-effective prototyping service. We have also developed our own direct digital manufacturing (DDM) procedures, which allow us to create prototypes using 3D printing, eliminating the need to invest in traditional tooling. We work with different prototype materials and methods to provide you with prototyping tools that best suit your project’s needs.

FAQ

What is OEM vs. Contract Manufacturing?

OEMs and contract manufacturers differ mainly in terms of control, intellectual property ownership, and design responsibility. An Original Equipment Manufacturer (OEM) produces products based on a client’s exact design, with the client keeping ownership of the brand and intellectual property. In comparison, a Contract Manufacturer (CM) typically manufactures parts or complete products according to the client’s specifications, while the client keeps control over the design and production requirements. In many situations, contract manufacturing is part of an OEM relationship, where the CM acts as the production partner or factory, and the client is the OEM.

Concept Evaluation & Feasibility

All ideas go through internal review and analytical screening. We assess cost, revenue potential, competition, longevity, and technical feasibility to ensure only the strongest, most viable concepts move forward.

Prototyping & Product Development

We develop and test prototypes to validate performance, quality, and manufacturability. Successful designs progress through controlled development stages toward full-scale production.

Functional & Aesthetic Integration

Our forward-thinking design approach brings together technology, materials, mechanics, and user experience into a single, cohesive product. We balance function and aesthetics to deliver solutions that perform exceptionally and maintain strong design integrity.

Saving you money, materials, and time

With decades of experience in injection molding, we can spot opportunities and risks in every project from a very early stage. By partnering with Rosti at the start of your project, you get product design support from skilled engineers and designers, plus insights from a supply and manufacturing perspective. Working with Rosti on your product design streamlines production, cuts waste, and ultimately saves both time and money.

With our product designers’ wide-ranging expertise, we can deliver complete solutions—from concept to reality—while letting you choose the level of day-to-day involvement you prefer. You can even consult us after the design phase has started. We’re happy to meet with you and your product designer to discuss your project’s feasibility and identify any performance or sustainability issues that could affect it. Together, we’ll design solutions that result in a final product everyone’s satisfied with.

The importance of user testing during the product development process

User testing plays a critical role in product design. By integrating user research into the product development process, product teams are able to gain insights about how a final product can best meet users’ needs. User feedback helps product teams identify potential issues that can be addressed early in the process, and it also allows product teams to get feedback from a diverse group of users who may be experiencing the product in different ways and therefore have different user experiences. Additionally, user testing allows product teams to understand usability concerns and prioritize which features should be added or removed to improve the product. Ultimately, user testing is an essential tool for helping product teams create products that are designed with their intended end user in mind.

How to consider the manufacturability of a product during design

When designing a product, it’s important to keep manufacturability in mind. The product must be designed with the eventual production process as a key consideration. A product designer’s role includes anticipating production complexities and considering cost-effective solutions. Making sure that design decisions factor in the limitations of the final product’s budget, available resources in the manufacturing plan, and how these limitations and resources can be used to create an optimally manufacturable product can help prevent delays and extra costs later on. Therefore, product designers should consider any challenges their product might face before manufacturing to ensure the product can be made without issues.

With years of engineering and manufacturing product design experience, we’ll work with you every step of the way to create a product that meets your needs and exceeds your expectations. We know how important it is for products to be designed quickly and efficiently, and our team will make sure everything meets your requirements while maintaining quality control standards.
