What is Cell Phone Case Injection Molding

November 21, 2022

When we talk about the cell phone case, we usually think of a specific material and shape. But for many people, the first thing that comes to mind is injection molding. This is because it's an old technique that has been used for decades to make products such as plastic bottles and toys. However, these days it's also used in one of the most popular industries: mobile phone cases! In this article, you'll learn how cell phone case injection molding works so that you can be sure your next mobile device will look great on the go.

What is Cell Phone Case Injection Molding

Cell phone case injection molding (CICIM) is the process of designing, fabricating, and injecting molded cell phone cases using full-color computer-aided design (CAD) software and a high-precision injection system to produce finished case products. The process involves making sample parts first, then modifying them to get the desired design as shown by using CAD software. After that, designers create a 3D model of the part on a computer screen and make changes to improve product flexibility, which can be done in real-time.

Cell phone mold design

In the mold design process, you'll need to determine how many pieces you want to make and how they should be made. You can also consider whether or not your final product will be finished by hand or machine.

To begin, you'll need to choose a material for the phone case that will contain all its components. The material should also be strong enough for whatever use it has in mind for its final application (i.e., durability). Next, decide whether or not you'd like any features on your phone case. This way it would be easier for customers when ordering from retailers.

Once these decisions have been made, you'll see exactly where everything fits together. Thanks to precise drafting techniques such as 2D drawings, which show off details about each piece's dimensions along with materials used throughout production processes.

Cell phone case injection molding machine

The cell phone case injection molding machine is used to mold mobile phone cases. It comprises the main frame, the main motor, and other components. The injection molding machine is of vertical and horizontal types:

Vertical type (vertical turret injection molding machine)

The vertical turret injection molding machine has a large number of vertical cylinders which move up and down according to their different heights concerning each other. This allows you to adapt your products with different sizes without changing your existing production line or purchasing new equipment.

Horizontal type (horizontal turret injection molding machine)

The horizontal turret injection molding machine has only one moving part (the horizontal cylinder). So it's easy for you to adjust its position during operation;

Phone Case Manufacturing Process

The phone case manufacturing process has the following steps.

The first step

The first step in the injection molding process is die preparation. It consists of cleaning out all impurities from the surface of both dies (mold). After that, they are placed together inside an oven at temperatures above 1000°C (1832°F). This step helps minimize any possibility for defects or poor-quality parts to form during production because it cleans up any foreign particles before they can affect your final product's quality or appearance!

Third step

The third step is the plastic injection mold process. In this process, manufacturers fill and inject the molten plastic into one-half of the mold cavity.

Fifth step

The fifth step in the injection molding phone case manufacturing process is ejection. This step consists of removing both halves of the mold from each other after they have cooled down.

Seventh step

The seventh step in the injection molding phone case process is the cleaning and cleaning your final product. This step also consists of inspecting both halves of your mold cavity for any defects that may have occurred during the manufacturing process.

Raw materials for injection molding phone case

The raw materials for cell phone cases are ABS, PC, PC+ABS, PA66, and so on. The raw material should be high quality and hard enough to meet the requirements of an injection molding machine.


In conclusion, Cell phone case injection molding is a great way to create high-quality, cost-effective, and quick products. It allows companies to manufacture products with precision and accuracy, making it ideal for companies that need their products to be manufactured quickly.
