Product Feature

IIR Material Advantages

Injection Molding Compatibility: Butyl rubber has excellent plasticity and fluidity, enabling uniform filling of mold cavities during injection molding and achieving high forming precision.

Rubber Properties: IIR rubber offers superior airtightness and chemical stability, maintaining product form and performance stability over extended periods in laboratory environments.

Aesthetic Advantages: Black IIR rubber is resistant to staining and can conceal minor imperfections resulting from the injection molding process, maintaining the clean appearance of educational molds.

Structural Design and Educational Functionality Integration

The upper and lower shells are produced as a single molded unit using a split-mold structure, enabling students to visually understand the principles of mold parting and demolding processes.
The square perforated structure simulates the connection points of joint components and can be used with teaching accessories such as metal rods and plastic shafts.
