1. Context
A Norway customer approached us with a request to customize a glass milk bottles with a unique threaded design. Unlike the threads of the standard bottle, the customer required a special screw size to ensure compatibility with his self-developed closure system.
2. Challenge
The main challenge is in the accuracy of the bottle neck thread. Since the client had requested a thread specification, which we had never produced before, even a slight deviation in diameter, thickness, or curve may result in disgusting unconventional with poor sealing, leakage, or shutdown. For this we needed to get extraordinary accuracy in mold design and production control.
3. Result
Although challenges were unavoidable, we are committed to our customers to compromise quality or misleading. To solve this issue, we invested in advanced mold development, repeatedly verified technical verification, and maintained close communication with the customer. Through several recurrences of testing and adjustment, we finally gave a custom bottle that meets sealing requirements, ensuring both product safety and customer satisfaction.

4. How did we do this
- Early phase – solution development: In the very beginning of the project, our engineering team worked at hand with the Norwegian client, so that they carefully analyze the unique thread specifications required for their custom milk bottle. Since the thread dimensions requested in our factory have never been produced before, every detail had to do a double check. We translated the client’s technical paintings and 3D images into an accurate mold blueprint, making sure that every measurement of diameter, pitch, and thread was excluded accurately. To reduce the risks, we also performed a digital simulation of the sealing process, predicted potential stress points and evaluated airtight performance before going into physical production.
- Sample production-translation and reaction: After confirming the mold design, we launched several small-batch test runs to make testing samples. These prototypes were sent to the customer for functional testing and response. Depending on their comments, our team carefully refined for the design of the neck, adjusting the depth of the threads, curvature angle, and the diameter of the mouth until the closed system was fully aligned with the cap. This recurrence process requires several amendments, but guarantees that the final product would receive innocent sealing, avoid leakage issues and construct customer trusts.
- Cost optimization and mass production: Once the final prototype was approved, we moved towards mass production. Our production team adapted the molding and anelying process to control the cost while maintaining high quality standards. To ensure transparency and customer confidence, we provided regular progress updates to the customer, detailed quality inspection reports and clear shipping schedule. This open communication not only ensured timely delivery, but also formed a foundation of long -term reliability, making the customer confident in launching his milk product with packaging that reflects both innovation and precision.
