Quality Built Into Every Step
Every stage of our workflow is engineered to uphold precision, repeatability, and quality you can trust.
Technical assessment
Before the production stage begins, our engineering team performs a technical assessment of your parts design. This includes an assessment on important factors such as material, surface finish, structure, process, and other details of your 3D and 2D drawings.
On-site inspection system
In precision machining, materials being worked on must be always at the right position. With an on-site inspection system, positions are examined automatically, and adjustments are made accordingly. Using an on-site inspection system further helps avoid issues at the early stage, saving cost and time.
Full-dimensional inspection report
For all orders, we provide full dimensional inspection reports on request. This report will include the following: quantity of parts, critical dimensions, threads and tolerances, thicknesses and depths, part appearance, etc.
Material verification
On our customer's request, we provide a certification of the material we used for making your parts. The report comes from the raw material manufacturer and usually includes material heat number, material grade, material dimensions, mechanical properties, chemical analysis, etc.
In-process quality control
At Dazao, we strictly obey the ISO9001:2015 requirements. The quality control staff conducts routine inspections for all parts that are being produced every 2 hours. This further prevents risks from happening.
Packaging
Ensuring that the parts we manufacture are of the high quality is important. We know about the unpredictability of logistics. Therefore, we make sure we lower the risk to the parts during our packaging process. Four layers of protection: 1. wrapping paper 2. EPE 3. foam 4. paper/wooden box are applied during the packaging process, ensuring that we deliver the most high-quality and beautiful parts to you.
