Firstly, we have a professional after-sales technical team, so you can rest assured about our after-sales service! If you have any dissatisfaction during the use of materials, please contact me in a timely manner. I will work with our R&D technical personnel to arrive at the site as soon as possible to analyze the reasons for the defects with you and your company's relevant technical personnel. We believe that we can provide you with a suitable improvement plan until you are satisfied!

Samples can be provided based on the weight of your product. For normal small products, we will provide 3-5 kilograms of testing materials for free. If the product has a relatively heavy unit weight, we can provide 8-10 kilograms of samples for free.

When it comes to quality, we are definitely more concerned than our customers. Quality is the lifeline and foundation of a company. Like the R&D team, we have an excellent quality control team. The quality control process includes establishing quality standards, implementing quality inspections, analyzing quality data, improving quality management, and handling non-conforming products. The company has a standardized laboratory with over 20 types of testing equipment. Relevant personnel strictly control incoming material inspection and process inspection according to standards.
