Wireless Earbuds Charging Box Injection Mold
The injection mold for the earphone charging case is a specialized tooling equipment designed for the production of wireless earphone charging boxes.
The mold features a high-precision design, ensuring the dimensional accuracy and surface smoothness of the charging case.
The intricate runner design within the mold guarantees uniform material filling, preventing defects such as shrinkage cavities and warping, thereby enhancing the overall quality and service life of the charging case.
The mold design also includes an automatic demolding mechanism, ensuring smooth product release during the production process, reducing manual intervention, and improving production efficiency.
Precision Size
The earbud charging case is designed with a sleek and compact form, boasting sophisticated exterior contours and a complex internal architecture, necessitating stringent precision standards. The mating tolerance for the upper and lower casing is maintained at 0.5mm, while the clearance for the button mechanism is set at 0.15mm. Additionally, the actuation stroke of the touch switch is specified to be 0.3mm. The design and fabrication of the plastic mold demand an exceptional level of precision.
Feeding System
The runner system is designed for uniform flow distribution, with CNC machining precision that yields a high polish surface finish. The gate diameter is specified at Ø 0.1mm. The ejector pin is equipped with an anti-skid channel measuring 0.2mm in width to avert ejection-related product misalignment, thereby preventing potential plastic product damage during the de-molding process.
Aesthetic Quality
A meticulously engineered independent water circuit has been incorporated to ensure uniform cooling distribution and to minimize the occurrence of shrinkage marks on the product's surface. Moreover, an internal venting insert is employed to manage the issue of air trap within the mold cavity, thereby ensuring a flawless molding process, and preserving the integrity and structural robustness of the molded component.
