Gating and degating are two important steps in the ultrasonic welding process, particularly when dealing with plastic parts.

Gating refers to the process of creating a small opening, or “gate,” in the part that allows molten plastic to flow into the mold during the injection molding process. The gate is typically located at the edge of the part and is designed to minimize the appearance of the gate in the final product.

Degating, on the other hand, refers to the process of removing the excess plastic material from the part after the injection molding process is complete. This excess material is typically located at the gate location and is removed by cutting or breaking it away from the part.

In ultrasonic welding, gating and degating can be important steps in preparing the parts for welding. The gating and degating processes can affect the strength and quality of the final weld, so it is important to carefully consider these factors.

For example, the location and size of the gate can affect the strength of the final weld, as a gate that is too large or located too close to the weld area can weaken the material and lead to failure. Similarly, the degating process must be carefully controlled to ensure that the excess material is removed without damaging the part or creating stress points that could weaken the weld.

Overall, gating and degating are important steps in preparing plastic parts for ultrasonic welding, and should be carefully considered in order to produce high-quality, strong welds.
