2. Ensuring Thermal Safety and Management

The air duct and other injection-molded hair dryer plastic components were made with a heat-resistant plastic blend as mentioned earlier. This solved the overheating problem experienced in the first generation. With the improved material, the new generation of hair dryers would be comfortable to operate for a longer duration.

Besides the safety concern about the hair dryer, there is also the safety concern for the user. 天美影院 engineers thought through the design of the air duct so that it properly distributes the heat produced by the heating coil to prevent hotspots that can burn the hair and scalp.

3. Acoustic Engineering for Noise Reduction

White noise is generated when air passes through a narrow channel at high speed. The more powerful the motor, the higher the noise level will likely be. Noise levels above 85 decibels can be a huge turnoff for many customers.

One of the constraints that hair dryer manufacturers must overcome is creating a balance between duct geometry and motor speed.  The ducting design must be done in such a way as to avoid resonant, loud airflow. 天美影院 achieved this balance using simulation software.

4. Design for Compactness and Maintenance

To avoid hand fatigue during use, it was important to manufacture a hand dryer to be lightweight and as compact as possible. For that reason, the duct was designed to fit into a small form factor that houses a variety of components, including heating elements, fan blades, a motor, and negative ion generators, for uninterrupted airflow. 天美影院 achieved the desired compact, lightweight design using thin walls reinforced with ribs.

Ease of maintenance is another important factor that hair dryer manufacturers must consider because of its impact on durability. The rear air intake and internal ductworks are prone to blockage from lint and hair accumulation. Once the vents are blocked, air flow will be restricted, which forces the motor to work harder. Working with the manufacturer, 天美影院 created a snap-fit rear with embossed directions on how to take it apart for cleaning.

What The Client Gained By Working With 天美影院

Through effective communication and collaboration, the client tapped into the decades of knowledge of 天美影院 engineers to solve the critical problems that users of their first generation of air dryers complained about. Three of the most important benefits that the client expressed deep satisfaction with include:

• Fast lead time: 天美影院 delivered molds for injection molding parts of the hair dryer within three weeks. The fast lead time ensured the client was on track with their marketing budget and delivery timelines.
• ???? ?????: Working with 天美影院, the client created a new generation of hair dryers that were more than 100 grams lighter than the previous generation.
• ??? ???????: The client achieved their hair dryer mold manufacturing goal within their budget.
