In the injection molding process, there is a technical detail that makes all the difference in the final result: efficient gas venting.

During mold filling, the air present in the cavity and the gases resulting from the volatilization of additives must be quickly evacuated. When this does not happen effectively, problems arise that compromise the quality of the part — from short shots to burn marks or weakened weld lines.

✅ Why is it so important to optimize gas venting?

Proper mold venting allows:

• Complete and uniform filling of the part
• Significant reduction of visual and structural defects
• Improved strength at weld lines
• Greater dimensional stability and reduced uneven shrinkage
• Better performance in thin-wall parts, even at high injection speeds

⚙️ How to ensure an efficient system?

The key lies in the strategic positioning of gas vents, always aligned with the material flow directions. A well-designed system ensures that air is evacuated at the right moment, preventing unwanted air traps.

In addition, the use of solutions such as “Venturis” brings additional advantages:

• They facilitate gas flow thanks to controlled clearance
• They promote more efficient and continuous extraction
• They contribute to process repeatability and consistency

✅ Final result? Greater efficiency and quality

By investing in optimized gas venting, you ensure not only better-finished parts, but also a more stable, productive, and competitive process.
