Injection Molding for Phone, Laptop & Tablet Cases

Plastic Injection Molding

Manufacturing rigid and flexible protective case components using selected thermoplastics, with attention to fit, structural details, and repeatable production quality.

Overmolding & Hybrid Structures

Combining rigid PC structures with flexible TPU components to achieve a balance of support, grip, and impact protection where required by the case design.

Custom Mold Development

Developing molds for model-specific protective cases, considering dimensions, openings, attachment features, wall thickness, and molded surface requirements.

JUNCHI combines mold development, manufacturing coordination, material selection, and quality inspection to support custom protective case projects. Our production capabilities are designed to help customers move from validated product structures to repeatable manufacturing.
