Meike MDMI Blu-Ray DVD CD Injection Mold 8cm Disc U-Tech Media Kata Systems

Meike MDMI Blu-Ray DVD CD Injection Mold 8cm Disc U-Tech Media Kata Systems

This is a Meike MDMI injection mold designed for producing 8cm optical discs — compatible with Blu-Ray, DVD, and CD formats. The mold is a precision steel tooling assembly used in a plastic injection molding press to form the disc substrate. It features multiple pneumatic air fittings (labeled AIR 1, AIR 2, AIR 3), coolant/fluid fittings, guide pins, ejector components, a centered sprue/gate bushing on the injection face, and sliding mold-half hardware. This unit was previously operated at a U-Tech Media USA production facility.

Applications

Injection molds of this type are the core tooling used in optical disc manufacturing. In a disc production line, polycarbonate pellets are melted and injected under high pressure into the mold cavity, forming the clear substrate that carries the data layer of a Blu-Ray, DVD, or CD. The 8cm format was used for single-track audio CDs, mini-DVDs (common in early camcorders), and certain promotional or specialty Blu-Ray titles. Disc injection molds are precision, high-value tooling items — they require careful alignment in a compatible injection molding press and are typically matched to a specific press platen size and shot volume. This mold would be of interest to optical disc manufacturers, contract molders, or research and development operations working with optical media substrates. The disc manufacturing industry for physical optical media peaked in the late 1990s through mid-2000s; 8cm specialty disc production continues on a smaller scale for niche markets.
