What are common defects and solutions for plastic extrusion?

Plastic extrusion is used a lot to make pipes, profiles, films, sheets, and other stuff. But when you’re extruding, you can get defects that mess up how the product looks and works. And that makes your costs go up and slows down your production. The plastic extrusion process faces issues like air bubbles, cracks, uneven […]

What’s the Difference between Plastic Extrusion and Injection Molding?

Plastic extrusion and injection molding are two common manufacturing processes used in plastics processing. They use different technologies and equipment in their production processes, so there are significant differences in their applications and cost efficiencies. This article compares the two processes to help you better understand their differences and application scenarios. Plastic extrusion is ideal […]

Why Is Back Pressure Important in Controlling Extrusion Quality?

Back pressure in extrusion is a critical parameter that significantly influences the quality of the final product. It refers to the resistance the molten plastic exerts on the extruder screw, ensuring the material is properly melted, mixed, and homogenized before being extruded through the die. Understanding and controlling back pressure1 is vital for achieving consistent […]

How Should You Adjust Temperature Profiles for Optimal Extrusion?

Extrusion is a widely used manufacturing process that shapes materials like plastics and metals into continuous profiles, such as pipes, sheets, or rods, by forcing them through a die. A key factor in achieving high-quality extrusion is the careful adjustment of temperature profiles1—the specific temperature settings across different zones of the extruder. Properly tuned temperature […]

Which Emerging Technologies Will Shape the Future of Plastic Extrusion? 

The plastic extrusion industry is undergoing a transformative shift, driven by innovations that enhance sustainability, efficiency, and versatility. As global demand grows for eco-friendly materials, high-performance products, and smarter manufacturing processes, emerging technologies are redefining what’s possible in plastic extrusion. From bioplastics1 to digitalization, these advancements promise a future where plastic extrusion meets modern challenges […]

What Are the Key Differences Between Plastic Extrusion and Other Methods?

Plastic manufacturing encompasses a variety of techniques, each tailored to specific product types and production needs. Among these, plastic extrusion1 stands out for its ability to produce long, continuous shapes with uniform cross-sections—think pipes, tubing, and window frames. However, other methods like injection molding, blow molding, compression molding, rotational molding, and 3D printing offer distinct […]
