From Injection to Assembly to Shipment: Step by Step into Our Quality Tracking Process
In international procurement, quality consistency often outweighs price. For buyers seeking long-term partnerships, ensuring that every shipment arrives with reliable specifications and stable quality is the true priority. At Enjoying Go Co., Ltd., we place quality at the core of our operations. From injection molding to assembly and final shipment, every stage is supported by a well-defined quality tracking system.
1. Starting with Raw Materials: The First Step of Quality Control
We source and apply PU, nylon, and recycled materials that comply with international standards such as RoHS and REACH, ensuring safety and reliability from the very beginning. This provides the foundation for durability and product performance.
2. Injection Molding: Ensuring Dimensional Accuracy and Structural Stability
During injection molding, we use precision temperature and pressure control systems to ensure that every caster wheel maintains consistent dimensions and tolerances. Random sampling is conducted for load-bearing and hardness tests, guaranteeing that wheels will not deform or loosen under long-term use.
3. Assembly: A Combination of Automation and Human Assurance
The assembly process integrates automated machinery with manual inspection. Automation secures efficiency and consistency, while manual checks cover critical details such as brake responsiveness, smooth wheel rotation, and axle tightness. This dual-layer control ensures every caster wheel shipped meets international standards.
4. Testing and Verification: Durability Comes First
Before shipment, each batch undergoes multiple tests:
-
Dynamic Durability Test – simulating over 10,000 rolling cycles.
-
Impact Resistance Test – confirming structural integrity under harsh conditions.
-
Static Load Test – verifying maximum load capacity for different wheel sizes.
All testing data is recorded, and upon request, inspection reports can be provided for full transparency.
5. Shipment and Traceability: The Final Step of Transparency
For every order, batch numbers and production dates are recorded to ensure full traceability. Should customers raise any feedback, we can quickly trace back through raw materials, injection, assembly, and testing stages to identify the cause and deliver precise solutions.
Conclusion
For Enjoying Go, quality is not a checkpoint at the end—it begins from the moment raw materials enter our factory. Our end-to-end tracking process is more than a procedure; it is our commitment to international buyers: every caster wheel is a mobility solution you can trust.
