Commitment to Quality
Bellyson is committed to providing excellence in machining, meeting or exceeding all customer and relevant interested parties requirements and delivering conforming products or machining services, while continually improving our Quality Management System.
We strictly follow ISO 9001 quality management system in the whole production.Our excellent QC team will guarantee the material quality,in processing control and outgoing quality control,just to ensure to meet customers’ requirements perfectly.Meanwhile,We are committed to improve our quality management and product quality continuously.
▶ Pre-Production Quality Evaluate
Before the production starts, Bellyson engineering team check and confirm on the material, structure, process, and other details of your 3D and 2D drawings. This prevents possible mistakes and unachievable requirements at the very beginning.
On the request of customers, we provide the certificate of raw material, and the Material certificates are provided by the raw material supplier and show the grade, properties,chemical composition of the material used for the order.
▶ First Article Inspection
To give our customers peace of mind before moving into production, we offer First Part Verification if you have any demands. First Article Inspection allows you to validate parts compliance to specifications before "Mass Production".
▶ In-process Quality Control
We strictly obey the ISO9001:2015 requirements and the quality control staff conducts rountine inspections for all parts that are being produced randomly.
▶ Final Delivery Check
All the critical dimensions be inspected as your technical drawing’s indication, This quality report where the critical dimensions of a small batch of a full order are inspected and recorded compared to the tolerances allowed. In addition,we provide full-dimensional inspection report if you have any demands.
Manufacturing standard for geometric tolerance
Typically,we can hold a CNC machining tolerance from 10.005"(±0.125mm) to ±0.0005"(±0.01mm). If tighter tolerances are required, 2D drawing of the critical dimensional with specific tolerances will be necessary. Our customer service will communicate with you and reply you.
All parts are deburred,break sharp edges etc standard finish.
