Boyi precision IND. Quality Control System

In order to deliver consistently high-quality parts that meet our customer needs, we employ a series of inspection methods, covering the entire manufacturing process.

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.

Packaging

The logistics is unpredictable, so we try our best to lower the risks for you. 4 layers of protection are applied on the package: 1. Wrapping paper 2. EPE 3. Foam 4. Paper/Wooden box. We dedicated to delivering the most high-quality and beautiful parts to meet your expectations.

Design Verification Program

To give our customers peace of mind before moving into production, we offer First Part Verification.

The program, which reduce risks and ensure the parts meet your requirements, is open for orders that include a minimum individual part quantity of 20 units or $1,000 USD order value.

Process

  • You request first article inspection for a quote that meets our design verification program requirements.
  • Boyi precision reviews the quote and grants you access to utilize DVP.
  • You sign the quote provided by Boyi precision and agree on DVP Terms and Conditions.
  • We produce two of the parts and sends them to you.
  • You receive and examine the parts, then inform Boyi precision that fullscale production may begin.
  • The full production starts and is delivered within lead time.

Quality Reports & Certifications

Full Dimensional Inspection Report

For every order on our platform, we provide a full dimensional inspection report on customers’ request. Dimensions are verified using a precision measuring instrument (caliper or gauge) and with a Coordinate Measuring Machine when required. The report includes:

  • Quantity of parts
  • Critical dimensions
  • Threads and tolerances
  • Thicknesses and depths
  • Part appearance

Material Certification

Process

Boyi precision industry strictly follow and implement ISO quality standards and have passed ISO 90001: 2015 certification.

Our Advantages of CNC Milling

After manufacturing is complete, an optical comparator, also known as a projector, is used to inspect components, precisely measuring their dimensions and comparing them to the original dimensions of the CAD model. Any inconsistencies detected by the projector are alerted in a detailed inspection report.
