Camera Exterior Parts – Molded Exterior Parts Set for DSLR Cameras – Nagatsu Precision Mold Co., Ltd.
Precision-Molded Parts for Camera Housings
Exterior parts for DSLR cameras using tunnel slide molds. Designed with up to 15 tunnel slide directions to reduce parting lines. Each tunnel slide is independently driven and locked for enhanced mechanical reliability.
Description
These camera exterior components are molded using multiple tunnel slides—up to 15 directions. The use of “slide within a slide” structure helps minimize parting lines (PL), improving surface precision. Each tunnel slide is mechanically driven and locked independently, contributing to stable mold operation.

Supplier
Components are manufactured by a supplier experienced in producing exterior parts for camera bodies and lenses, using multi-directional tunnel slide technology.
Specification
Application: DSLR camera exterior parts (lens/body/cover/mirror)
Mold feature: Up to 15 tunnel slide directions
