How we check your Prototype?
Parts Drawing Checking | Jucheng Precision
 
Drawings Checking

we will check every item on the BOM like quantity, material, process, and surface finish requirements, and see if they are in accordance with the quotation. Meanwhile, our engineering team will check 3D and 2D drawings to see if there are any design errors, in accordance, with interference, and confirm all the tolerance are okay to be machined.

Meanwhile, DFM will be sent when it is necessary.
Incoming Material Inspection | Jucheng Precision  
Incoming Material inspection

We asked our material supplier to provide certification and paste marks for all the materials. And we will check the materials with Spectrometer to test the material chemical components.
In Processing Checking | Jucheng Precision
 
In processing checking

In this stage, we will go both with visual checking and manual checking.

Our experienced and skillful craftsman will check the parts with 3D drawings. 

We understand that it is very essential to check the parts when machining and avoid time-wasting. If necessary, we can provide you with the first sample when it comes to batch production.
Final Inspection | Jucheng Precision  
Final Inspection

We have 6 well-trained engineers in our QA department.

We can provide inspection reports like 3D scanning reports, Cleanness reports,100% dimensional reports, PPAP, Control Plans, etc.
