Before you met Siedery, did you encounter the following problems?


Newly designed products are difficult to get professional evaluation and advice from manufacturers on CNC machining materials and surface finishes; suppliers are slow to quote.


The delivery period is too long, which affects the project progress; the vendor's business counterpart does not understand the technology and process, is unprofessional or unstable, and the communication is not smooth.


Parts with high precision requirements are only told after production that the precision is not up to par or that the inspection tools are not available and cannot be tested, affecting the assembly and project schedule.


A project involving multiple processes needs to be sent to several vendors separately to be completed, incurring too much time cost and communication cost during the period, and after-sales problems cannot be solved.

We are trusted by

See why our customers trust us

Trust comes from good service and quality delivery of parts on time.
I was dubious about my initial collaboration with Siedery as I had not worked with them before. I tried to send them some very challenging, high tolerance CNC machined parts with the aim of having a look at them. The communication went well, the team at Siedery were very professional and I received the samples within a very short time and I was blown away by the quality and accuracy of the parts. I am really pleased with this professional service from them. We have been working very well together over the years and have recommended several friends to place orders with them.


We have been ordering CNC parts from Siedery for over 4 years. Before working with Siedery, I was often frustrated by the lack of reliable suppliers until I came across Siedery and was completely overwhelmed by the quality of their machining and service. We have always received accurate quotations very quickly after sending in a request for quotation, which has helped our business so much that we are happy to stick with Siedery for the long term and would recommend them to my friends in the industry.


I have been working with another CNC machining company in China for 2 years, the service was very good at the beginning, but as the orders increased there were quality problems and delayed in delivery, I chose to give up after no result in communication. Siedery has been a great help to me over the past 5 years. My business in the USA is getting better and better because I have met such a reliable supplier Siedery.

I am very grateful for the help I have received from Siedery over the past 5 years and we will be working together more and more.
