Quality Control Process
Learn the most stringent inspection methods we applies over the course of the entire manufacturing process.
Pre-production
Technical assessment
Before the production stage begins, our engineering team performs a technical assessment on 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.
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 production
On-site inspection system
In precision machining, it is important that materials being worked on is always at the right position. With on-site inspection system, positions are examined automatically, and adjustments are made accordingly. Using on-site inspection system further helps avoid issues at the early stage, saving cost and time.
In-process quality control
At Promise Technology, to ensure quality at high level, the quality control staff conducts routine inspections for all parts that are being produced every 2 hours. This further prevents risks from happening.
Before delivery inspection
Full-dimensional inspection report
For all orders, we provide inspection report on request. This report will include the following: quantity of parts, critical dimensions, threads and tolerances, thicknesses and depths, part appearance, etc.
Packaging
Ensuring that the parts we manufacture are of the highest 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.
