At JS Precision Company, we are experts in injection molding. But we understand that not everyone knows the difference between injection molding and extrusion. So, let us take a moment to explain the difference.
Extrusion molding and injection molding are both plastic manufacturing processes, but they differ in many ways. Extrusion molding is the process of heating plastic pellets and forcing them through a die to create a continuous profile or shape. Injection molding, on the other hand, is the process of injecting molten plastic into a mold cavity to create a solid part.
One of the main differences between the two processes is the way the plastic is introduced into the mold. Extrusion molding uses a hopper to feed plastic pellets into a screw conveyor, where they are melted and pushed through a die. Injection molding, on the other hand, uses a hopper to feed plastic pellets into a barrel, where they are melted and injected into a mold cavity.
Another difference between the two processes is the types of parts they can produce. Extrusion molding is ideal for producing long, continuous shapes, such as pipes, tubes, and profiles. Injection molding, on the other hand, is ideal for producing complex, three-dimensional parts with intricate details, such as gears, housings, and medical devices.
The precision of the finished product is also different. Extrusion molding produces a uniform and consistent product, but it may not be as precise as injection molding. Injection molding can produce highly precise parts with tight tolerances, making it ideal for applications where accuracy is critical.
Speed is another factor to consider. Extrusion molding typically produces parts at a slower rate than injection molding. This is because extrusion molding produces a continuous profile, whereas injection molding produces a discrete part. However, extrusion molding can be faster for producing long, continuous products, such as pipes or tubing.
Finally, there is the cost factor. Extrusion molding is generally less expensive than injection molding, as it requires less equipment and setup time. However, injection molding can produce higher-quality parts with greater precision, making it worth the investment for many applications.
