Product Q&A

Q:Are you a trading company or factory?

We are a manufacturing factory.

Q:Do you have FDA certificate for the materials?

Yes, FDA is very important for the food processing machines.

Q:How do you control the quality?

Quality control is very important to avoid material mixing and poor quality. We control the quality from beginning to the end. We only have 304 and 316L two different materials. 100% inspection on raw materials. During production, different materials in different places. After materials are finished, we choose 10% for inspection. If there is 0.1% problem in 10%, then no excuse to go ahead for inspecting 100% of the materials.

Q:About chemical components

This is first concerning for customers. We take our materials to our laboratory for each lot. You may ask for the laboratory report any time.

Q:If there is any quality problem, how do you solve it?

We are not 100% perfect, there is some quality problem. We try our best to provide the correct materials in the beginning, so we need less time for quality problem. If there is any quality problem, we take the responsibility. We believe what we are doing together, it will get back tomorrow. If we leave our responsibility, customers will leave us. If we always take our responsibility, we keep our customers with us.
