We control product quality through the following steps:

1. After we hire the workers, we will have the professional training. Still they will be tested by the manager, if pass the test, he will undertake thie relative work.

2. When the purchase dept. buy the raw material from the original supplier, we still have the test for it, just keeping its quality good. Once finding that something is not efficient, then we will resend it to supplier and order again.

3. Each week, the workers will test the machines to guarantee it. For example, we will take several pieces patch to test its temperature range. If it is available compared with the standard, then store and package it, later seperately send to the customers.
