China Contract Manufacturing

Contract Manufacturing Services & Process

Sertus specializes in bringing new ideas to market through contract manufacturing. We've helped inventors and manufacturers develop innovative products and improve existing lines. With in-house expertise and access to industry consultants, we streamline the journey from concept to market, saving time and costs.

Product/

Component Development

At the development stage, Sertus’ China Sourcing Experts will help you evaluate concept details, review or aid in the creation of concept drawings, provide research on similar products and on component or raw material sources, offer preliminary bill of materials and cost analysis, and create or assist in the creation of computer aided design (CAD) mechanical drawings – all of this as part of our contract manufacturing services. We will also work with you to develop a model to test the functionality of the product, making any alternations as deemed necessary or as agreed.

Pre-Production Samples

Once the design is finalized and functionality assured, a control sample will be produced. Sertus will leverage its procurement resources and extended supplier relationships to identify appropriate vendors, finalize price negotiations (with the prototype vendor and components suppliers), audit of tooling materials to specification, offer timeline and schedule confirmation, develop tooling as required, coordinate the creation of your prototype, perform quality control, test functionality, analyze results and create an action plan for adjustments or for production.

Final Production and Delivery

Our purchasing teams follow a structured process, executing purchase agreements to protect against delivery and quality shortfalls. We enforce strict supplier standards through systematic control samples, IT-integrated monitoring, and on-site engineers overseeing production. Our QC managers ensure orders are processed on time, while final inspections and QA follow-ups help prevent disruptions. With a hands-on approach to contract manufacturing, we manage every stage efficiently—getting your product from concept to shelf quickly, reliably, and to the highest standards.
