Banana Gate Injection Molding in China

Key points to Banana Gate Injection Molding

Manufacturing is a simple business of making goods by hand or by a machine. Once the goods are made, they are sold to a customer. There are several different types of manufacturing processes in this world. China Injection Molding is one of them.

What is Injection Molding & an Injection Molding Machine?

Injection Molding is one of the most commonly used manufacturing procedures for the production of plastic parts. As it is used for the molding of plastic, it is also known as plastic injection molding. Different types of products are produced using an injection molding technique – plastic trinkets, automotive parts, toys, mobile cases, bottles & containers.  Injection molding is done with the help of an injection molding machine, raw materials & mold. This process consists of 3 valuable steps – designing of product, designing of mold & the manufacturing process. The injection molding machinery uses a melt, inject, cool & pack procedure by converting granules of raw plastic into final molds.

Injection mold design is an important factor in the China plastic injection molding machine & each injection design consists of a gate to allow the melted plastic flow to be injected into the cavity of the Chinese mold. Different issues may arise if the wrong scale of the gate is chosen like uncompleted filling, molding shrinkage & excessive residual stress. There are two types of gates for injection molding machines-one is manually trimmed & the other one is an automatically trimmed gate. Under these two categories, there are 9 different gates called Direct Spruce Gate, Side Gate, Fan Gate, Pinpoint Gate, Disk Gate, Rin Gate, Film Gate, Tab Gate & Submarine Gate. Depending on the part of the design, the gate can be small or large. The location of the gate is also important in the manufacturing process as it decides how the plastic will enter & form into a mold.

China is one of the major producers of plastic injection molding. China mold makers have made notable progress in the last few years in the business of China injection molding. Companies from around the world come to this country with the wrong expectations of purchasing cheap China mold. To avoid delivery fraud, it is better to look for manufacturers around your location. This will also save delivery time.

Banana Gate Injection Molding

This type of molding machine uses the banana gate for its production. The banana gate is similar to the tunnel or submarine gate & it is curved like a banana. This is a new type of gate which is quite trendy in the China plastic injection molding machines. These gates are very useful as they do not leave any marks on the plastic surface. Because of its magnificent curvy shape, it can reach below the part & allows the plastic to be injected into the secluded area of the part. Banana gate injection molding is normally used for ABS & HIPS materials. If these types of gates are not properly designed, then the machine can break easily.

China injection molding is a standard process for manufacturing plastic involving raw materials & molds. It is one of the most cost-efficient manufacturing processes. Injection mold machinery is capable of producing high volumes of high-quality plastic.

How to make gas assisted injection mold?

The gas-assisted injection molding is a process that involves the traditional, low-pressure process of injection molding. This process uses pressurized nitrogen gas to force material into a mold. Let’s find out more about gas-assisted injection molding.

Basically, this process is used to produce big parts of plastic using complex designs and beautiful surface finishes. Normally, this process is a great choice for making skins, cabinets, bezels, doors, equipment covers, and handles.

Internal Injection Molding

As said earlier, this process injects pressurized nitrogen gas into a mold. Actually the nitrogen gas is passed through the gas channels for displacing the material through the creation of hollow sections.

The molten resin is pushed against the wall of the cavity until the solidification of the path. The constant pressure of the gas prevents the shrinkage of the part. In addition, it reduces internal factors, sink marks, and surface blemishes. So, this process can work well to hold curvatures and tight dimensions.

External Injection Molding

In this type of injection molding, the material is pushed into the mold. However, the gas is pushed in a very thin layer between the mold core and the back surface of the component. So the front surface of the component is forced against the other side of the cavity of the mold. as the gas cools down, different sides of the component replicate the mold surface.

Basically, this process is suitable for plastic parts that feature large surface areas, especially those parts that require beautiful surface and detailed textures. In this process, the sink and warp marks are removed because in nitrogen gas maintains the material condition.

Just like internal gas assist, the bosses and support ribs are molded into the component and produce the same level of tolerance and dimensional stability. In the same way, molding pressure produces less stress wear and tear.

Cost Considerations

This process also helps save a lot of money. Typically, these processes require a lot less force than traditional injection molding. Therefor it helps reduce the component chords costs and produces less stress as well.

Actually, the mold pressure results in reduced wear and tear. Therefore, there would be less demand for pricey aluminum tooling. Moreover, the parts made are lightweight which will help reduce the freight expenses and boost material handling.

Design Benefits

Moreover, this technology results in a lot of performance and design benefits. For example, multiple parts with different thickness off walls can be molded.

Converting different components to Gas Assist

This type of injection molding is a better alternative to the large metal parts. Therefore, it is possible to eliminate expensive, heavyweight, corrosive components like panels, access doors, enclosures hand covers.

In short, this was a brief introduction to gas-assisted injection molding. Hopefully, this article will help you understand the concept much better.
