Production process:

What can we do for you?

Pre-sale service:
We will arrange a professional salesman for deal with your technical requirements and precision requirements, and then according to product line drawing and our factory production capacity, we will offer you the most competitive price based on the quickest and least cost ( if we can't offer the size in your need, we will inform you before offering. ), to make it possible to cooperate with you.

On-purchase service:
Once we reached agreement and clear producing details, An engeneer would touch base with you for auditing the drawing and planing the production. In the producing, production assistant will continually inform the salesman about production progress and quality information, ( during in this time, we will control quality strictly), and the salesman will inform all information to you, to insure deliver goods on time and quality assured.

After-sales service:
Since the company began, we always understand every part is very important for customer, even though lack one part or a bad product may make all system can't work well, so quality is life for us. Because all parts are precision, so it must be professional. Perhaps there are some bad products could be made, but according to customer's feedback, we will check problem and remake them in time. At the same time, in order to avoid the bad products are made again, we will improve the way of producing.
