China Dispatch: Adventures in Case Manufacturing

Sheet Metal & Stamping Process, Continued

The stamping process in this picture shows where the dies are compressed to form the shapes within the metal. The amount of pressure and force used to do this can vary from as much as 150 to 250 tons, depending on the amount of compression necessary to form the shapes. As you can imagine, this is a dangerous process! Each station is equipped with sensors to protect the Chenbro workers from injury. If the sensor detects that a hand (or anything else, for that matter) is near the stamping machine the machine will not engage. Worker safety is highly important to Chenbro, and they take every safety precaution to protect their employees.

In this picture, the final metal side panels are inspected prior to being stored for later use. Even though Chenbro uses many production lines, it is not possible to produce all of the metal parts at one time. Parts are stored and then brought together again when it is time for the metal housing to be assembled.

Chenbro takes quality very seriously. At the end of each production stage there is a quality assurance (Q.A.) check to make sure that the products meet exact established quality standards. The Chenbro Q.A. team members wear orange striped uniform shirts to indicate to the other team members that they are responsible for inspection and quality. Quality and consistency are very important to Chenbro, and they strive to make sure that each case meets the same high levels of quality. Chenbro empowers each employee with the responsibility to ensure quality throughout the entire manufacturing process; if an employee notices or finds a quality defect, they have the ability to stop the production line. This means that each Chenbro employee is responsible for quality, not just the Chenbro Q.A. teams. This gives Chenbro excellent quality control, since everything is checked at least twice.
