Pre-Production Quality System

Technical assessment

Before the production starts, Boyi precision 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.

Material verification

On the request of customers, we provide the certification of the material used in the manufacturing process. The report comes from the raw material manufacturer and usually includes: material heat number, material grade, material dimensions, mechanical properties, chemical analysis, etc.

During Production Quality Control

On-site inspection system

It is fundamental and vital in precision machining that the material block is always at the right position. With on-site inspection system, the machines automatically examine the positions, and make adjustments accordingly. This avoids the issues at the early stage, and help save cost and time.

In-process quality control

At Boyi precision, we strictly obey the ISO9001:2015 requirements. The quality control staff conducts routine inspections for all parts that are being produced every 2 hours.

First article inspection

To give our customers peace of mind before moving into mass production, we offer First article inspection for die casting orders, and can be specially requested for CNC machining. We will examine the sample part, and provide inspection report with images. We will ship the part for your verification when necessary.

Before Delivery Final Checkup

Full-dimensional inspection report

For orders on Boyi precision platform, we provide full dimensional inspection report on customers’ request. The report includes: quantity of parts, critical dimensions, threads and tolerances, thicknesses and depths, part appearance, etc.
