1. Why is the vent system important?
When hot plastic is injected into the mold, the air inside the mold must be removed to avoid the formation of air bubbles. Without an effective vent system, these air bubbles can cause defects in the product, such as:
- Air bubbles: Reducing the aesthetics and durability of the product.
- Surface defects: Causing dents or cracks on the product surface.
- Decreased product quality: Reducing the load-bearing capacity and strength of the product.
2. Functions of the vent system
2.1 Air removal
The vent system helps expel air from the mold during the plastic injection process. This ensures that the plastic can fill the entire cavity without being obstructed by air.
2.2 Preventing air bubbles
When air is vented out, the risk of air bubbles forming in the product is significantly reduced. This not only improves product quality but also minimizes material waste.
2.3 Increasing production speed
An efficient vent system reduces the waiting time between injection cycles, thereby increasing production speed. This is crucial in high-output manufacturing lines.

3. Types of vent systems
Vent systems can be divided into two main types:
3.1 Natural venting
This is a simple system that uses small holes in the mold to allow air to escape. However, this type may not be effective in all situations.
3.2 Forced venting
This system uses fans or pumps to remove air from the mold. It is commonly used in applications that require high precision and product quality.

4. Considerations when designing vent systems
- Vent location: Vent holes should be strategically placed to ensure easy air escape without interfering with the injection process.
- Vent hole size: The size of the holes needs to be carefully calculated to ensure optimal performance without compromising mold strength.
- System maintenance: The vent system should be regularly inspected and maintained to ensure effective operation.
Conclusion
The vent system plays a vital role in the plastic injection molding production process. Investing in the design and maintenance of an effective vent system not only enhances product quality but also optimizes the production process.
