Which Plastic Injection Machines Feature a 40mm Netstal Vented Screw

The 40mm diameter vented screw from Netstal is designed to handle a range of plastic materials, especially those requiring venting to remove gases during the melting process. The vented design helps reduce defects like bubbles or voids in the final product by allowing trapped air and moisture to escape.

Which Plastic Injection Machines Feature a 40mm Netstal Vented Screw - With an overall length (OAL) of 51.61 inches, this screw size balances throughput and precision. It fits medium-sized injection units, making it ideal for applications that demand consistent quality and moderate shot weights.

Netstal Injection Machines Using the 40mm Vented Screw

Several Netstal machine series incorporate the 40mm vented screw, each serving different production scales and material types. Here are the key models:

Elion Series

The Elion series represents Netstal’s modern all-electric and hybrid machines. These machines are known for energy efficiency and precision control. The Elion 800-270 model frequently uses a 40mm screw diameter, including vented configurations, to process technical plastics and specialty materials.

• Use case: High-precision parts requiring tight tolerances

• Material compatibility: Engineering plastics, composites

• Benefits: Reduced cycle times, consistent melt quality

  
  

SynErgy Series

The SynErgy series is a high-speed hydraulic lineup popular for medium clamping forces. Models like the SynErgy 600, 800, and 1000 commonly feature 40mm screws as a standard bore size.

• Use case: General-purpose molding with fast cycle times

• Material compatibility: Standard thermoplastics, some vented materials

• Benefits: Reliable performance, easy maintenance

  
  

EVOS Series

EVOS machines combine hybrid technology with high performance. Their injection units support a wide range of screw sizes, including 40mm barrels and screws. This flexibility allows manufacturers to switch between materials and shot sizes efficiently.

• Use case: Versatile production lines with varying product types

• Material compatibility: Technical plastics, vented materials

• Benefits: Energy savings, adaptability

  
  

Legacy Models

Older Netstal machines like the N350/150 also use 40mm screws. While these models may lack some modern features, they remain reliable for many molding operations, especially in facilities with established equipment.

• Use case: Established production lines with legacy equipment

• Material compatibility: Common thermoplastics

• Benefits: Cost-effective, proven durability

  
  

Specialized Units: PETForm and PET-LINE Systems

Netstal’s PETForm and PET-LINE systems are designed for PET preform production. Depending on the preform size and shot weight, these systems may use 40mm screws to optimize melt flow and cycle times.

• Use case: PET bottle preform manufacturing

• Material compatibility: PET resins

• Benefits: High output rates, precise control over preform quality

  
  

Why Choose a 40mm Vented Screw?

Selecting the right screw diameter and type impacts product quality and machine efficiency. The 40mm vented screw offers several advantages:

• Improved gas venting: Reduces defects caused by trapped air or moisture

• Balanced shot size: Supports medium shot weights suitable for many applications

• Material flexibility: Handles a broad range of plastics, including technical and vented materials

• Compatibility: Fits multiple Netstal machine series, easing parts sourcing and maintenance

  
  

Practical Considerations for Using a 40mm Netstal Vented Screw

When integrating or replacing a 40mm vented screw, consider these factors:

• Material type: Ensure the screw design matches the polymer’s venting needs

• Machine compatibility: Confirm the screw length and diameter fit the injection unit

• Cycle requirements: Vented screws may slightly affect cycle times due to venting zones

• Maintenance: Regular inspection of venting channels prevents clogging and performance loss
