Weilong Quality System : Systematic Quality Management for Reliable Solenoid Performance
Table of Contents
At Weilong Intelligent Technology, quality is the backbone of every product we produce. As an experienced solenoid producer catering to automotive and industrial customers, we realize that in most applications involving solenoids, stability and consistency in performance are often paramount.
In light of this, quality at Weilong is considered a process that should run through design, production, testing, as opposed to a final inspection activity as it would in conventional companies.
Chapter 1 : Quality Philosophy
Quality is Baked into the Process
Furthermore, we are convinced that solenoid performance integrity can never be accomplished through the use of inspection alone, but through carefully managed processes instead.
Our quality philosophy is founded on:
Engineering Design Validation
Engineering Design
Controlled materials and production processes
Data-driven testing and verification
Full traceability and accountability
This ensures that quality is maintained from the development of the prototype to mass production.
Chapter 2 : Certified Quality Management Systems
Weilong operates with internationally recognized quality management standards and is certified for:
ISO 9001 – Quality Management System
IATF 16949 – Automotive Quality Management System
Our certifications demonstrate that our company strictly complies with process control, risk management, traceability, and continuous improvement standards to achieve support for automotive, industrial automation, as well as new energy sectors.
Chapter 3 : Design Quality & Engineering Validation
Quality has to begin with design.
Before a solenoid goes into production, it is validated according to its functional, environmental, and reliability specifications.
Examples of design quality activities are:&#
Magnetic circuit analysis and optimization
Structural Feasibility and Tolerance Analysis
Thermal behavior and duty cycle analysis
Review of manufacturability and compatibility with processes
The designs are validated by lab testing, ensuring that the performance characteristics do actually work as designed.
Chapter 4 : Incoming Material Quality Control (IQC)
The performance and lifespan of solenoids are dependent upon the quality of raw materials used and purchased parts. Our Incoming Quality Control system is designed to make sure that only material meeting our requirements reaches our production lines.
IQC includes a number of key steps:
Material specifications and conformity checks.
Performing dimensional and visual inspections.
Conducting sampling inspections, adhering to established standards.
Supplier documentation review.
This is an important initial stage because it eliminates material-related issues from reaching the production line.
Chapter 5 : In-Process Quality Control (IPQC)
The quality control process is integrated within every key process of manufacturing.
Our quality engineers are also closely integrated in manufacturing, as we strive for process stability and consistency.
“In-process controls refer to the Dimensional checks in CNC machining and stamping.
Verification of the coil windings.
Checking the assembly alignment and fit.
Process monitoring & periodic sampling.
It is a proactive approach that can reduce variability by ensuring uniform results are achieved during mass production.
Chapter 6 : In-House Laboratory Testing
It has an in-house solenoid lab, which is a crucial element for product development as well as quality during production. The solenoid lab is equipped for testing.
The testing capabilities of the lab include:
Force pull or push measurements.
Response time and stability of actuation.
Tests for the increase in temperature and thermal resistance are carried out. Life cycle tests, as well as “off” durability tests, are also done. Consistency in performance is also sampled.
It is ensured that all testing data is properly documented and traceable. This provides an objective confirmation of quality and reliability.
Chapter 7 : Final Quality Inspection (FQC)
No solenoid product is allowed to be shipped from our production unit without going through the final check. This is to ensure that the quality meets our own manufacturing requirements and the other specifications that have been provided by the customer. These final steps in the inspection procedure involve:
Functional testing.
Electrical testing.
Chapter 8 : Verification of force performance.
A visual evaluation of looks and workmanship.
Verification of labeling, packaging, and traceability.
Only the items that have cleared the quality tests will be shipped.
Traceability and risk management are of prime importance here.
They are widely used in the manufacture of solenoids.
Our quality system allows us to trace:
The materials we work with and sourced from.
Production batches, and the parameters that are used.
Inspection & Test Records.
It also makes traceability very easier for rapid root cause analysis, application of corrective actions, or improvements.
Continuous improvement is a continuous process.
We systematically review production data, laboratory reports, and customer responses to assess areas for improvement.
These corrective and preventive actions are accomplished through processes, which enables us to strengthen the reliability of our products and processes.
Chapter 9 : Reliability is what we are all about.
Our intention is more than just meeting requirements upon point of delivery, as our concern is to ensure consistency over the whole life span of our products.
Through rigorous quality management, the saleable product manufactured, and quality testing, Weilong provides solenoids for their clients to use under tough conditions.
Chapter 10 : Quality Control – FAQ
Q1: What quality management systems are you using?
We adhere to ISO 9001 and IATF16949 certified quality management systems to ensure that we meet international and automotive industry standards.
Q2: Is your quality system compatible for automotive applications?
Yes. Our IATF 16949 certification ensures that we are meeting the stringent demands of the global automotive supply chain in traceability, process controls, and continuous improvement.
Q3: How is a mass-produced item made consistent? Consistency in mass-produced products is achieved by controlled processes, inspection during production, work instruction, and performance sampling.
Q4: Before shipping, what are the types of inspections done?
The final inspections that each of the solenoids receives before being shipped out include functional tests, pull/push force checks, visual checks, and inspection of labeling.
Q5: Do you have traceability for solenoid products?
Yes. We use traceability for materials, process, and inspection records, which can be easily analyzed if any problem of quality occurs.
Q6: What is your approach to quality or corrective action? Quality issues are addressed through a systematic corrective and preventive action process. Root cause analysis is done, and corrections are made with its effectiveness verified.
Q7: Can your quality system fulfill customer-specific requirements? Yes. We can coordinate our quality control measures to satisfy their specifications, standards, and inspection criteria, particularly for the automotive sector.
