Operations, R&D upgrades
China makers of sunglasses are improving production to maximize raw materials and lower defect rates.

In line with this, suppliers are installing computerized management systems such as ERP to reduce overhead, control workflow and enhance efficiency. The program also eliminates dependence on individual workers.

Moreover, factories are outfitted with new equipment, including plastic-injection and lens-coating machines.

To strengthen R&D, companies put up design centers together with well-known science and technology institutes, including Zhejiang University.

Plants also get specialists and skilled workers to speed up the release of new models.

Many leverage CAD, CAM or PDM software as well.

As a result, more makers are turning out original styles, which command higher profits than OEM versions.

But despite efforts to innovate, product imitation is becoming a major concern among suppliers. Specifically, there are cases where manufacturers report missing samples of original designs, and find later on that other companies have released styles similar to that.

To counter the situation, businesses require workers to protect trade secrets and other proprietary information. Molding subcontractors are also made to sign confidentiality agreements.
