Our Team
"Dear Ms. Candice,Have a nice day., First of all, I would like to thank you fast delivery and good quality products. I am very pleased with the quality of the materials used and the workmanship. Doing business with you for the past 3 years has truly been a pleasure. I hope to continue this rewarding relationship for years to come."
"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"
"I recently visited DCW to perform a supplier audit and risk assessment. 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."
"I'd like to thank you again for your time and patience yesterday during my visit. Your quality system is very strict, i was impressed. This is perfectly what we are looking for in term of process. It was interesting thank you."
A: We are professional PTFE product manufacturer with ISO9001, ISO14001 certificated, and all material are RoHS, compliant.
A: Sorry, Free samples are not available for the custom parts. But after you place the order, samples cost would be return. Which is "FREE" in some way.
A: First, please send your drawing to our sales representative, they will forward all the information to our engineer and evaluate our capacity, a detail proposal will be reply with 24 hours.
A: In this situation, firstly please send us some photos of your sample, we will evaluate. If our factory can produce, then secondly we will ask sample from you, the Draftsman will make drawings according your sample, PS: Make sure your sample is new and unused.
A: Payment welcome T/T, West Union and Paypal.
A: Generally, tolerance is based on the design and material, we are now able to reach +/-0.001(inch) for certain parts.
A: 7-15 days for normal order, we can achieve 1 week delivery for urgently order.
A: Document will be offer based on your requirement, like inspection report, packing list, material certification, date sheet, MSDS, COC and so on.
A: Life-long technology support, and 60 days return policy(Should make sure all the parts are new and unused).
A: Your sales representative will in charge of after-sales service, plz contact them if you have any questions.
