Happy Customers & Partners

I recently visited DCW to perform a supplier audit and risk assessment. Having never been to China but holding onto some pre-concieved notions about Chinese industrialization, I was pleasantly surprised to find how well-executed and managed this factory is. The employees are treated like family. The staff is diligent in their duties and professional in their execution of them. They can certainly stand alongside any company in the world. I look forward to working with Dechengwang on our current endevour and all possible projects in the future.

Quality of PTFE is great, better than our previous. Design is 5 stars! Will re-order from you, but need them rounded edges and only one square edge of back tip. Thank you.
