Injection molding machines rely heavily on precise components to ensure consistent, high-quality production. One critical part is the feed screw, which directly influences the melting, mixing, and injection of plastic materials. For those using Autojector vertical injection molding machines, finding the right feed screw is essential. Complete Plastics offers a 1.00" Autojector feed screw designed specifically for these machines, combining durability and performance to keep your production running smoothly.

Why the Feed Screw Matters in Injection Molding


The feed screw plays a vital role in the injection molding process. It moves raw plastic pellets through the barrel, melting and mixing them before injecting the molten plastic into the mold. A well-designed feed screw ensures:


  • Consistent melting of plastic material

  • Efficient mixing to avoid defects

  • Precise control over injection pressure and speed

  • Reduced wear and tear on the machine


For vertical injection molding machines like the Autojector, the feed screw must match the machine’s specifications to maintain optimal performance.


Features of the 1" Autojector Feed Screw


Complete Plastics offers a feed screw tailored to the Autojector vertical injection molding machine with the following specifications:


  • Overall Length: 21.75 inches

  • Length-to-Diameter Ratio (L/D): 16:1

  • Feed Section Length: 8.12 inches

  • Transition Section Length: 4.00 inches

  • Metering Section Length: 4.00 inches


These dimensions are carefully engineered to provide the right balance between melting efficiency and material throughput. The 16:1 L/D ratio is ideal for many thermoplastics, offering enough length for thorough melting without excessive residence time that could degrade the material.


How the Feed Screw Design Supports Performance

The feed screw is divided into three main sections, each with a specific function:


  • Feed Section: This is where raw plastic pellets enter and begin to move forward. The 8.12-inch length allows for steady feeding and initial compression.

  • Transition Section: At 4.00 inches, this section gradually compresses the material, increasing pressure and temperature to prepare the plastic for melting.

  • Metering Section: The final 4.00 inches ensure the plastic is fully melted and homogenized before injection. This section controls the flow rate and pressure for consistent molding results.


This design supports smooth operation and reduces the risk of defects such as unmelted pellets or inconsistent shot sizes.


Benefits of Choosing Complete Plastics for Your Feed Screw


Selecting the right supplier for your feed screw is as important as the screw itself. Complete Plastics offers several advantages:


  • Precision Manufacturing: Each feed screw is made to exact specifications for the Autojector vertical injection molding machine.

  • Durability: High-quality materials and heat treatment processes extend the life of the screw, reducing downtime and replacement costs.

  • Customer Support: The team at Complete Plastics is available at 770-417-6983 or sales@completeplastics.com to help with questions and orders.

  • Fast Delivery: Keeping your production line running means quick turnaround times on orders.


These benefits make Complete Plastics a trusted source for injection molding components.


Practical Tips for Maintaining Your Feed Screw


To get the most out of your 1" Autojector feed screw, consider these maintenance tips:


  • Regular Cleaning: Remove any residue or buildup to prevent contamination and wear.

  • Inspect for Wear: Check the screw flights and barrel for signs of abrasion or damage. Replace parts as needed.

  • Monitor Processing Conditions: Avoid overheating or running the machine at excessive speeds that can damage the screw.

  • Use Compatible Materials: Ensure the plastic resins used match the screw’s design parameters for best results.


Proper care extends the life of the feed screw and maintains product quality.


When to Replace Your Feed Screw


Even with good maintenance, feed screws wear out over time. Signs that it’s time to replace include:


  • Inconsistent melt quality or color streaks in molded parts

  • Increased cycle times due to poor material flow

  • Visible wear or damage on the screw flights

  • Higher energy consumption during operation


Replacing the feed screw promptly prevents production issues and costly downtime.
