An injection screw valve is used in injection molding machines to control the flow of plastic material from the hopper into the mold. The valve on the end of a screw rotates within the barrel, which moves the plastic material forward. An electric motor typically drives the screw and can be adjusted to control the […]
The design of the extrusion feed screw plays a critical role in determining the quality of the extruded product or part. The feed screw is a vital component of the extruder, and its design can influence various aspects of the extrusion process and the final product. A well-optimized screw design ensures efficient melting, mixing, and […]
The barrel used in an extrusion or injection molding machine will affect the final parts, the machine’s overall efficiency, and the project budget. Selecting the right barrel for the materials to be processed is essential. To further avoid production issues, manufacturers must also closely monitor their selected materials’ effects on their equipment. Processing abrasive, corrosive, […]
When it comes to injection or extrusion molding, the barrel and the screw are the most critical components in the machine. They must be made from high-quality materials that are exceptionally strong and offer high temperature, wear, and corrosion resistance. Most barrels are made from 4140 and micro-alloy series steel due to the strength of […]
Your screw and barrel are among the most important and expensive parts of your injection or extrusion machine. If there is a problem with them it can shut down your entire process. Wear is one of the main issues you will face with your screw or barrel. Thankfully wear on the components is a slow […]
Extruder screws and barrels are exposed to different wear and corrosion environments as they operate. The first sign of wear is typically a maximum processing flow rate reduction. The screw is designed to rotate within the barrel and, as such, has a threaded flight lead diameter that is only slightly smaller than the barrel diameter […]
Currently, many manufacturing industries are struggling with various issues – the inability to obtain essential raw materials or components to create their products, labor shortage issues, much longer delivery times, and more. Increasing costs are also driving a looming slowdown in many sectors. So, what can you do to maximize profits and save on expenses […]
Choosing the right screw for injection molding can significantly impact the throughput of your machine. In addition, it can also determine how successful your project will be. The screw choice can ensure that there is no material degradation and the material is properly melted. The end results are a more efficiently molded product reducing scrap […]
