The  trimming machine is designed to remove burrs, flash, and gate residue from injection, blow, or compression molded plastic parts, such as cups, bowls, preforms, and housings. Using rotary dies or cold-cutting blades, it performs fast and smooth trimming through punching or rolling. The cut edge is clean without white marks, and the process generates no dust or odor, avoiding material discoloration or warping caused by hot cutting. The machine supports automatic inline operation with robots or conveyors, significantly improving the appearance and dimensional consistency of plastic products.

1. Clean Cut Without Damage: Utilizing cold-cutting technology and high-hardness rotary blades, it delivers smooth, white-mark-free, and non-stringing edges. It avoids material discoloration, burning, or warping caused by hot cutting, making it especially suitable for transparent or light-colored plastic parts.

2. Dust-Free and Odorless: The mechanical punching or rolling process generates no dust or irritating odors, eliminating the need for additional dust extraction systems. This ensures a clean and eco-friendly production environment that meets workshop hygiene and safety standards.

3. High-Efficiency Automated Production: The machine supports single or multi-station simultaneous trimming and can be integrated with vibratory bowls, conveyors, or robotic arms for automatic loading and unloading. Processing thousands of parts per hour significantly reduces labor costs.

4. Flexible and Quick Changeover: The modular quick-change design for blades and stations allows product changeovers within 5–10 minutes. It accommodates various plastic parts such as cups, bowls, lids, preforms, and housings, making it ideal for multi-variety, small-batch production.

5. High Dimensional Accuracy: Equipped with positioning fixtures and limit mechanisms, the trimming position deviation is controlled within ±0.1mm, ensuring excellent product consistency and reducing scrap rates.
