Why Regular Maintenance and Calibration of Plastic Extrusion and Injection Molding Machines is Essential for Optimal Performance

in Extrusion, Injection Molding, Manufacturing

Regular maintenance and calibration of plastic extrusion and injection molding machines is vital for ensuring their optimal performance and longevity. By performing routine checks and servicing, manufacturers can prevent potential breakdowns and malfunctions that could disrupt production and lead to costly downtime. Maintenance and calibration ensures that the machines operate within precise tolerances, which is […]

Which Valve Is Best for Your Plastic Injection Molding Project?

in Injection Molding, Valves and End Caps

A plastic injection screw valve is a crucial component in the plastic injection molding process. It is the part of the injection molding machine responsible for controlling the flow of molten plastic into the mold. The screw valve operates by rotating and moving axially within a heated barrel, melting plastic pellets and pushing the molten […]

How does the material used affect the wear on the injection/extrusion screw?

in Custom Screws, Extrusion & Injection Screws

The material used in plastic injection and extrusion applications can significantly affect the wear on the machine’s screw due to various factors such as abrasiveness, thermal properties, viscosity, chemical interactions, and more. Here are the most common issues and how they impact screw wear: How can you mitigate wear on the screw? Mitigating wear on […]

Preventing Splay Defects in Injection Molded Parts

in Injection Molding

Splay defects in injection molded parts can be streaks, lines, or visible discoloration on the surface of the molded product caused by premature solidification of the plastic material before it fully reaches and fills the mold cavity. The term “splay” describes the radial streaks that extend from the gate area toward the outer edges of […]

How do injection screw valves affect your machine’s performance?

in Valves and End Caps

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 […]

How does the feed screw design affect the quality of the extruded part?

in Custom Screws, Extrusion, Extrusion & Injection Screws

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 […]

Are injection/extrusion barrel linings a good idea?

in Barrels

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, […]

Why choose a bimetallic barrel for your plastic extrusion or injection?

in Barrels

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 […]

Three internal signs your injection or extrusion screw is worn and needs to be replaced

in Extrusion & Injection Screws

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 […]

Causes of extrusion screw wear & how to minimize them

in Extrusion, Extrusion & Injection Screws

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 […]
