During the injection molding process, the product has injection ports, so it is necessary to remove the sprue (also known as the nozzle). There are several ways to remove the sprue:

1. Automatic removal within the mold; 2. Manual removal; 3. Ultrasonic removal; 4. Tooling cutting; 5. Laser cutting;

Due to factors such as slow removal speed of gates and difficulty in controlling the size of gates during cleaning, ultrasonic vibration is necessary to greatly improve the speed and smoothness of gate removal;

The principle of Yuwo ultrasonic vibration is to use the principle of ultrasonic resonance to create resonance between the thin and narrow gate position and the ultrasonic wave, and to break it without leaving any burrs at the gate position;

What kind of gate structure is suitable?

Yuwo Ultrasonic Engineer has compiled some experience for you, as shown in the following picture: oblique cut type,

Thin and narrow structures are prone to vibration, while thicker gates are difficult to vibrate in a short period of time; You can choose between punching or laser cutting methods;

From a material perspective, which materials are suitable for vibration drop?

Firstly, products with low melting points and brittleness are prone to vibration and falling off; For example: ABS,PC, Acrylic,

The case image is as follows:

Case 1: As shown in the figure below, ABS material                            Case 2: As shown in the figure below, ABS material

Case 3: As shown in the figure below, PC material    Case 4: As shown in the figure below, PC material
