01. Technical evaluation

Before the production phase begins, our engineering team will conduct a technical evaluation of your part design. This includes the evaluation of important factors such as materials, surface finish, structure, process, and other details of 3D and 2D drawings.

02. Material verification

According to the customer's request, we provide certification for the materials used to manufacture your parts. The report comes from the raw material manufacturer and usually includes material calorific value, material grade, material size, mechanical properties, chemical analysis, etc.

Professional homework
quality standards

We have developed specialized operation manuals to effectively control the quality of mass production

  • Guidelines for Parts Processing and Inspection Operations
  • Engineering Department Operation Manual
  • Process Operation Manual
  • Guidelines for Mold Processing and Maintenance Operations
  • QC Inspection Operation Manual
  • Quality Assurance System Diagram
  • Punch Press Operation Manual
  • Guidelines for Wire Cutting Processing Operations

Quality visualization and traceability

We provide comprehensive quality documentation for all projects, including inspection reports, material certifications, and compliance documents

Raw material inspection

The incoming raw material inspection report is a systematic record of the raw material inspection process, data, and results. It is not only the basis for determining whether the raw materials are qualified, but also the core document for subsequent quality traceability and supplier evaluation.

Visual inspection

We verify whether each product meets the customer's standards for color, texture, and overall appearance.

Dimensional quality inspection

For products with simple structures, we use vernier calipers, miniature calipers, and altimeters; For products with complex structures, we use coordinate measuring machines (CMM) to ensure accurate measurements.

Performance quality inspection

We evaluate the functionality of the components to ensure that threaded holes and other parts are correctly installed during the assembly process.

Quality Integration Report

We provide a final inspection report that details all inspection processes and results.

RoHS Report

According to the requirements, we provide a RoHS report to confirm that the materials comply with RoHS standards.

Inspection and testing equipment

Strictly implement 100% full inspection, independent testing center with supporting equipment
