The 90mm silicone extruder machine is a crucial piece of equipment in the manufacturing of silicone-based products. Silicone is widely used in industries such as automotive, medical, electronics, and consumer goods due to its properties like flexibility, heat resistance, and durability. The extruder machine is designed to transform raw silicone material into usable forms such as gaskets, seals, tubes, and other custom profiles. To appreciate how this process works, it is essential to understand the structure and key components of a 90mm silicone extruder machine.

The structure of a 90mm silicone extruder machine is made up of several key components, each designed to perform specific functions in the extrusion process. These components work in tandem to ensure that the silicone is processed effectively, producing high-quality finished products. Below are the important parts of the machine:

a. The Hopper

The hopper is the starting point for the raw silicone material. This component is a large container that holds the silicone pellets or rubber compound before they are fed into the extruder. The hopper is designed to ensure a continuous and uniform feed of material into the machine, which is critical for maintaining consistent output.

In many cases, the hopper may also include a vibrating mechanism or a feeder to help regulate the flow of the material. This ensures that the machine receives the right amount of silicone without clogging or overloading.

b. The Feed Section (Barrel and Screw)

The barrel and screw assembly is the heart of the extruder. The screw, which is typically 90mm in diameter, is responsible for driving the silicone through the extruder and ensuring it moves forward as it undergoes heating, mixing, and shaping. The barrel, which houses the screw, is a long cylindrical tube where the extrusion process takes place.

The screw has several sections with varying pitches to perform specific functions:

The feed section is where the raw silicone enters and is moved toward the heating section.

The melting section provides the necessary shear forces and heat to soften the silicone.

The metering section ensures the material flows at a controlled rate, helping to maintain consistent product dimensions.

The screw diameter, in this case, 90mm, is chosen to strike a balance between the material's flow rate and the volume of silicone that needs to be processed. A 90mm screw is ideal for medium to high-volume production.

c. The Heating System

The silicone material must be heated to the right viscosity to ensure it flows smoothly through the machine and takes the shape of the die. The heating system typically consists of electric heaters or heating bands wrapped around the barrel. These heaters ensure that the silicone reaches the processing temperature before it is forced through the die.

In some machines, temperature control is managed by a combination of thermostats and temperature sensors embedded in the barrel. These sensors ensure that the silicone is heated evenly, preventing any areas from becoming too hot or too cold, which could affect the quality of the finished product.

d. The Die (Shaping Tool)

The die is a critical part of the extrusion process, as it determines the final shape of the silicone product. Once the silicone has been heated and mixed, it is forced through the die, which can be customized to produce different shapes such as tubes, gaskets, seals, and profiles.

The die can have a variety of designs depending on the required product specifications. For example, for silicone tubing, the die will have a circular shape, while for gaskets or seals, it might be rectangular or custom-shaped. The precision of the die directly affects the final dimensions and quality of the silicone product.
