In terms of raw material selection, priority should be given to first tier brands such as DuPont to avoid significant fluctuations in raw material quality between batches. All factories are equipped with spectrophotometers, etc. to ensure that the instruments on the work site are in a stable state. In the production process, in addition to the stable and optimized production process, specific threaded components will also be arranged and combined to ensure the stability of the final product performance. The company has purchased a relatively complete set of instruments for testing the physical parameters of the mother batch, equipped with various small equipment to simulate customer processing processes, and strives to keep pace with customer production scenarios.
