Guide to producing silicone products with injection molding machines

Silicone products are a common sight in many industries, from healthcare to automotive and beyond. They are versatile, durable, and offer a range of unique properties that make them ideal for a variety of applications. But have you ever wondered how these products are made? The answer lies in injection molding machines. In this article, we will explore the intricate process of producing silicone products with injection molding machines and give you a glimpse into the world of silicone manufacturing.

What is an Injection Molding Machine?

Before we dive into the process of producing silicone products with injection molding machines, let's first understand what an injection molding machine is. An injection molding machine is a piece of equipment used in the manufacturing process to produce a wide range of plastic and rubber products. It works by heating up the raw material and injecting it into a mold, where it cools and solidifies into the desired shape.

How Does an Injection Molding Machine Produce Silicone Products?

Producing silicone products with injection molding machines is a complex process that requires precision, accuracy, and attention to detail. Here is a step-by-step guide to help you understand the process.

Step 1: Raw Material Preparation

The first step in producing silicone products with injection molding machines is to prepare the raw material. Silicone is a synthetic rubber that comes in the form of pellets or powder. The raw material is then loaded into the injection molding machine's hopper, where it is heated to a specific temperature and melted.

Step 2: Injection

Once the raw material is melted, it is injected into a mold cavity under high pressure. The injection molding machine has a screw that pushes the molten material into the mold, filling every cavity and void.

Step 3: Cooling and Solidification

After the material is injected into the mold, it needs to cool and solidify before it can be removed. The mold is cooled using a water circulation system, which helps the material solidify and maintain its shape. The cooling time depends on the size and thickness of the product.

Step 4: Ejection

Once the material has cooled and solidified, the mold is opened, and the product is ejected. The ejection system of the injection molding machine pushes the product out of the mold and onto a conveyor belt or a container for further processing.

Step 5: Post-Processing

After the product is ejected, it may require additional post-processing to achieve the desired shape, texture, and appearance. This may include trimming excess material, sanding, polishing, or adding a coating or paint.

Why Use Injection Molding Machines for Producing Silicone Products?

Injection molding machines offer several advantages over other manufacturing methods for producing silicone products. Here are a few reasons why they are the preferred method for silicone manufacturers.

High Production Efficiency

Injection molding machines are capable of producing a large volume of products in a short amount of time, making them ideal for mass production. The process is automated, which reduces the need for manual labor and increases production efficiency.

Precision and Accuracy

Injection molding machines offer a high degree of precision and accuracy, ensuring that every product is consistent in shape and size. This makes them ideal for producing complex and intricate designs that require high levels of precision.


Injection molding machines are a cost-effective solution for producing silicone products. The high production efficiency, precision, and automation of the process help reduce labor costs and minimize material waste.


Injection molding machines are versatile and can produce a wide range of silicone products, from small components to large parts. They can also produce products with different shapes, sizes, and colors, making them ideal for a variety of industries and applications.

Advantages of liquid silicone injection machine

In conclusion, liquid silicone injection molding machine of liquid silicone injection molding is a cycle of steps, each stage mainly includes quantitative filling, melting and plasticizing, pressure injection, mold filling and cooling, mold opening and removal

The liquid silicone injection molding machine is effective and can quickly complete the action of liquid silicone injection molding. The left and right molds independently control the injection system, which is easy to adjust the key load during the production process, suitable for rapid production of large quantities, improving the production efficiency and saving raw materials.

The equipment parameters of liquid silicone injection molding machine have been digitized. The liquid silicone injection molding machine digitizes the pressure and output speed, while the pneumatic system of the feeder system is digitally adjusted using electric proportional valves. The operator can now visualize the important parameters of the machine on the touch screen.

Liquid silicone injection molding machines are commonly used to manufacture liquid silicone baby products such as pacifiers, bottles, nipples, gums, spoons, bowls and other baby feeding products. The liquid silicone injection molding machine can also be used to make secondary encapsulation molding products, such as liquid silicone cell phone waterproof accessories, headphone connectors, card holders, cell phone encapsulation sheaths, glass tempered film encapsulation, etc.
