Quick Prototyping Solutions for Precision Structural Components in Consumer Electronics

Blog Article

As a worker at Junying, I have had the opportunity to be part of some truly innovative projects. One of the most exciting challenges we recently undertook was for a leading smart wearable device manufacturer. The client needed to rapidly prototype a new high-end smartwatch case, which had to be both lightweight and durable, with a zinc alloy shell that balanced aesthetics and functionality. The project required us to deliver a prototype within 7-10 days, a timeframe that is both challenging and typical in the fast-paced world of consumer electronics.

The Challenge of Rapid Prototyping

Smart wearable devices, such as TWS earphones and smartwatches, are known for their rapid iteration cycles. Manufacturers need to validate their designs quickly to stay ahead of the competition. This means that the time from design to prototype must be minimized. The client's requirements were particularly demanding: a zinc alloy shell with ultra-thin walls (0.8mm), high-gloss surface finish, and precision fit with tolerances of ±0.02mm.

Our Solution: Die Casting and CNC Machining

To meet these stringent requirements, we leveraged our expertise in die casting mold service and CNC machining. Our team worked tirelessly to deliver a solution that would not only meet the client's specifications but also exceed their expectations.

Step 1: Mold Design and Optimization

The first step was to design the mold. Using UG NX software, our engineers optimized the mold flow to ensure that the ultra-thin walls (0.6mm) could be accurately cast. This step was crucial to ensure that the zinc alloy would flow correctly and fill the mold without defects. The mold design was completed within 48 hours, a testament to our team's efficiency and expertise.

Step 2: Zinc Die Casting

With the mold design ready, we moved on to the die casting process. Our high-pressure die casting machines were used to produce the initial zinc alloy shell. The challenge was to ensure that the thin walls were filled without any voids or porosity. Our experienced operators and advanced equipment made this possible, resulting in a high-quality casting that met the client's specifications.

Step 3: Precision CNC Machining

The next step was to refine the casting through precision CNC machining. Using a high-speed CNC machining center, we performed intricate operations such as the outer circle turning of the bezel (with a roundness error of less than 0.003mm) and micro-milling of the touch control area. This step ensured that the final product had a high-gloss surface finish and precise fit.

Step 4: Surface Treatment

The final step was to apply a PVD vacuum coating to the zinc alloy shell. This not only enhanced the surface hardness to over HV200 but also provided a visually appealing finish. The combination of zinc alloy and PVD coating ensured that the smartwatch case was both durable and aesthetically pleasing.

Delivering the Prototype

The entire process, from design to delivery, was completed within 7 days. The final prototype was a testament to our team's dedication and expertise. The zinc alloy shell had ultra-thin walls, a high-gloss surface finish, and precision fit with tolerances of ±0.02mm. The client was extremely satisfied with the results, and our quick turnaround time allowed them to enter the trial production phase two weeks earlier than anticipated.
