Product Introduction

 

Achieve the perfect can end with the advanced engineering of our Can Necking Machine ST-B31VA. With over 60 years of experience in necking machine design, this model represents a culmination of precision, speed, and reliability. It is specifically engineered to neck welded can bodies according to set proportions, ensuring a uniform diameter reduction essential for subsequent flanging and seaming operations. The vertical design saves valuable floor space and facilitates easy integration with downstream processes. Whether you are producing beverage cans, food containers, or aerosol cans, the ST-B31VA bottle necking equipment for cans delivers the high-volume output and meticulous control required to maintain the integrity of printed can body graphics, minimizing distortion and ensuring your product looks as good as it performs.

 

Product Feature and Application

 

Key Features:

  • High Throughput Performance: Engineered for high-output operations, the Can Necking Machine achieves speeds of up to 350 cans per minute, making it ideal for large-scale beverage and food can production lines.
  • Accurate Diameter Reduction: Six precision-engineered necking heads work in sequence to gradually reduce the can diameter with minimal material stress, ensuring consistent, high-quality results.
  • Graphic Integrity Control: Advanced control mechanisms precisely manage the stretching or dislocation of printed patterns during necking, preserving the can's decorative graphics.
  • Robust Lubrication System: Features a dual lubrication approach: a central automatic system for underside components and manual lubrication points for upper parts, ensuring long-term reliability and ease of maintenance.

 

Applications:

  • Designed for necking processes in three-piece beverage and beer can production lines.
  • Ideal for conditioning food can bodies prior to the double seaming process.
  • Suitable for manufacturing aerosol cans that require a precisely reduced neck diameter.
  • Applicable to any high-speed production environment where consistent and accurate diameter reduction of welded can bodies is essential.

FAQ

 

Q: How does the machine handle different can diameters?

A: The ST-B31VA is designed to accommodate a range of can diameters from 202D to 401D. Changing between sizes within this range typically involves adjusting or changing the necking dies and associated change parts. The inverter speed control allows for optimizing the cycle time for each specific can size.

Q: Can this machine neck printed cans without damaging the graphics?

A: Yes. A key feature of this Can Necking Machine is its ability to precisely control the necking process to minimize the stretching or dislocation of printed patterns. This ensures that the decorative graphics remain intact and visually appealing after necking.

Q:How many stages are required in a can necking process?

A: The number of stages in a can necking process depends on the final diameter reduction and material properties. Multi-stage can necking machines are commonly used to achieve smooth deformation without damaging the can body, ensuring high-quality results in high-speed production lines.
