Precision Injection Molding Applications in Smartphone Manufacturing
(1) Casing Manufacturing
The thin-wall molding process enables the design of ultra-thin shells measuring 0.5–1 mm, balancing structural strength with lightweight body construction.
Employing polycarbonate or acrylic materials combined with a high-gloss finish to achieve a mirror-like surface effect.
Relying on high-precision mold control, we ensure that the dimensions of detailed features such as camera holes and button slots are accurate, thereby guaranteeing assembly quality.
(2) Internal support members
The dimensional tolerances of core components such as the motherboard bracket are controlled within ±0.05 mm, meeting precision assembly standards.
Using nylon reinforced with glass fiber enables the simultaneous fulfillment of both structural strength and lightweight requirements.
Supports the compact internal layout of mobile phones and ensures stable installation of electronic components.
(3) Interfaces and Buttons
The frequently used keys are precision-injected for a crisp tactile feel and long-lasting durability.
The connector’s dimensional accuracy reaches ±0.02 mm, ensuring stable signal and power transmission.
Combining sealing technology achieves IP67-level waterproofing, effectively protecting the internal circuitry.
