Selecting the right people is the key

Selecting an overseas sheet metal manufacturer could be an overwhelming task. There may be many metrics you want to take in evaluating your suppliers, but above all, it is most important that the people you choose to work with are likely-minded, easy to communicate, hard-working, and fully dedicated to their tasks.

Our 3 ways to ensure your sourcing experience...

(You may take these metrics for evaluating new suppliers)

Design evaluation and DFM

Before starting a project, we will evaluate your drawings and check whether your design is ready for shop floor production:

  • Bend radius, bend relief, hole diameter, hole to hole distance, hole to edge distance, and more;
  • The dimensional and geometrical tolerances. They have to be achievable and yet ensure proper functioning;
  • What kind of issues may arise in the manufacturing of this kind of product.

By doing so, we are showing you that all details have been checked, and we have experience in similar products.

Detailed QC reports

While in production or before shipment, we will send you detailed QC reports, which may include the dimensional report, material certificates, and more (like salt spray test report and so forth).

  • When we do the dimensional inspection, we list a range of the multiple readings. This will take a lot more time but makes the inspection result much more reliable.
  • Taking measurements is a skillful job, it requires understanding how dimensions are interrelated and full comprehension of how the product is assembled and functioning. Only trained personnel will be assigned to do this job.

Pictures and videos to show details

  • We also send high-resolution pictures to show details of the product;
  • Sometimes videos will be a more effective way because pictures are less complete in showing details;
  • Text messages will come along with the pictures and videos to explain what information we want to present to you;
  • We recommend using online chatting tools (like WhatsApp, Skype, and WeChat) to send and receive pictures and videos.

We have our quality inspection personnel in place and will not let flawed products shipped to you.
