At Yuanfang there are a Project Manager and a Project Engineerassigned for every project.

The Project Manager is responsible for the project from initialdiscussions with customer representatives until the project issuccessfully completed.

For the customer this means: One Project - One Contact.

The Project Engineer is responsible for the technical side of eachproject. He delegates the work to the different departments and is inclose contact with the Project Manager.

The customer gets weekly updates about the project status.

Team Discussions

Round-Tables at crucial project stages for the project's success.(Project Kick-Off, DFM, Mould Design, Mould Trial Result, Modifications)

Before Injection Mould Delivery, our project manager will make a tooling check to ensure our molds go to customers in good status and quality.

■ Documentation

Tool Book

For every mold we provide a Tool Book. it gets filled

during the project implementation and we ship it to the

customer together with each mold.

The Tool Book is a real book and should stick with the

mold for quick access at any time. It contains all useful

information about the mold's design,application and

maintenance. lt contains also a digital copy of itself.
