For mold engineers who live-stream technical content, the teleprompter is not just a script holder—it’s a precision tool. Using Douyin Live Companion’s built-in teleprompter, I’ve found that the default scrolling speed (often 20–30 words per minute) is too slow for explaining complex mold structures like slider actions or runner systems. Set the speed to 35–45 WPM, and adjust the font size to 28–32 pt so you can glance at it without losing eye contact with the camera. More importantly, segment your script by mold components: cavity, core, ejection, cooling, and venting. Each segment should be 2–3 sentences max, with a hard pause marker (e.g., “//”) to trigger your next visual aid—like a 3D cross-section or a machining clip.

In practice, the teleprompter’s mirror mode is a game-changer for mold demos. When you rotate your phone or tablet to face the camera, enable the horizontal flip so the text reads correctly on your side. I also recommend using the “keyboard highlight” feature to mark critical numbers—such as shrinkage rates (0.5–0.8% for ABS) or cooling time calculations (e.g., 12 seconds for a 2.5 mm wall thickness). This keeps your delivery sharp without fumbling for notes. For live Q&A, set a secondary prompt line at the bottom of the teleprompter with common questions like “What steel grade for high-cavity molds?” and pre-loaded answers—this cuts response time by half and makes you look more authoritative.

One overlooked detail is the teleprompter’s background transparency. In a bright workshop, drop it to 60–70% opacity so the live view of your mold or CNC machine remains visible behind the text. Also, sync the scrolling with your hand gestures—when pointing at a core pin, pause the scroll manually. I’ve tested this across 20+ live sessions, and it reduced verbal fillers (“um,” “you know”) by roughly 40%. For mold-specific topics, always keep a “cheat sheet” of key parameters (draft angles, gate types, mold base sizes) in the teleprompter’s quick-reference section.
