Today's case is how to use the way high precision plastic injection mold banana gate, without the need to manually cut the nozzle?

The function of the gating system is to pass the molten plastic through the injection molding machine nozzle, and enter the mold cavity through the gating system under the condition of high temperature, high pressure and high speed. The design of pouring has a very important influence on the quality of the product and the molding cycle. The pouring system consists of the main channel, the runner, the gate and the cold material cavity.

The main problem that needs to be solved: the nozzle is prone to breakage, and customers hope that different products will appear in the 1*1 cavity

We choose the high precision plastic injection mold banana gate

In general, the glue feeding point of the large nozzle is around the product. In order to facilitate the smooth filling of the glue, what should we do?

As shown in the figure, we will steal the glue at the glue point: 0.3~0.5mm, and increase the unilateral side by 30% to make a 30-degree slope differentiation

The banana gate is being used more and more because of its unique advantages, but many bad problems can often be seen in the mold test due to unreasonable structural parameters.

The following is a summary of the application of the structure design of the mold banana feeding

1. Features of banana feeding:

1. Automatic water cut

2. The glue point is concealed

3. The glue can be fed at the same height of the PL surface

Second, the common adverse phenomena of bananas into the glue:

1. The top of the nozzle is constantly

2. The fracture is ugly

3. The appearance of the glue point has punch marks

4. Nozzle ejection rebound and crash flower products

Below is a video of our final mold in production after change the high precision plastic injection mold banana gate

With the improvement of people's living standards, people have higher and higher requirements for the quality of injection molded parts that are common in life. The OEM high precision plastic injection mold method of injection molds directly affects the quality of the injection molded parts. In order to reduce the subsequent manual gate removal, the injection method on the mold is designed to be in the form of a submerged gate. 

The choice of high precision plastic injection mold banana gate is a successful attempt of our company. We hope that we can have more attempts in injection molding in the future and accumulate more experience to serve customers.
