Every opportunity to improve manufacturing efficiency and cost-effectiveness is worth exploring. YIFENG has been committed to enhancing our customers’ benefits at every process stage, from plastics design to distribution. After the initial molding and part fabrication process is complete, YIFENG provides value-added services to facilitate better results in the supply chain. Our sub-assembly and kitting services reduce the work required later while ensuring a high level of quality from molding to assembly.
Giving this responsibility to the manufacturer streamlines the process and reduces the need for additional labor at the product’s final destination. They assemble multiple parts into a single unit and ensure everything is ready for those working on plastic assembly systems. All in all, these efforts can save much time and effort.

YIFENG, with its decades of expertise in assembly and manufacturing for the appliance, medical, and precision instrument industries, is a reliable partner. We provide timely, high-quality solutions at competitive costs, even for highly decorative parts, ensuring you can trust us with your most complex projects.
YIFENG has the ability to support our partners in participating in the global economy. We can ship completed assemblies and sub-assemblies to wherever you need them, empowering you to expand your reach. Ask us how we can support your project, from the largest jobs to low-volume, high-complexity assemblies, and feel connected to a global network of manufacturing support.

We can provide plastic parts assembly services according to customer needs, which means we can assemble plastic parts that match each other. However, we do not offer assembly services for electrical products or final finished products such as electrical components.
Shipping by ship to the USA takes about three weeks and to Europe about five weeks. If your part is more minor, we can ship it by air, in which case it arrives in about four days.
Once the plastic products are assembled, they will occupy less space, making it easier to ship them. However, due to the extended transportation time, we will implement protective measures for the products before shipment to guarantee their integrity. Communicating your specific requirements during the quotation period is essential for us to accurately assess the final unit price of the product.
