/ Vacuum Forming /
Thermoforming Process for Ear Covers：
Ear covers are typically produced using the thermoforming process. The plastic sheet is first heated until it becomes soft, then placed over the mold. A vacuum is applied to pull the softened sheet tightly against the mold surface. After cooling and setting, the product is trimmed to its final shape.
Quality Control：
- Each product undergoes 100% full inspection
- Only parts that meet the ±0.003 mm dimensional tolerance are accepted
- Ensures measurement accuracy of ±0.2°C for the final product
