Key Factors When Selecting Nitrogen Gas Springs

1. Stroke Length

Make sure the selected nitrogen gas spring provides sufficient stroke length to meet the requirements of:

Die cushion movement

Mold opening and closing operations

Part ejection requirements

Avoid bottoming out during operation to ensure safety and extend service life.

 

2. Force Requirements

Calculate the required:

Initial force (F_initial)

Final force (F_final) at full compression

Force ratings are typically measured in:

daN

Newton (N)

lbf

Selecting the correct force rating ensures stable mold performance and prevents excessive loading.

3. Operating Environment

Consider the actual working conditions of the mold.

For applications involving:

Stamping lubricants

High temperatures

Dust or contamination

Choose nitrogen gas springs equipped with:

Special piston rod wipers

High-temperature sealing systems

Enhanced contamination protection

4. Connection Systems

For applications using multiple connected nitrogen gas springs through a manifold system, ensure the manufacturer provides compatible:

Hoses

Control panels

Pressure monitoring equipment

A complete connection system helps improve safety, pressure control, and maintenance efficiency.

Need Help Selecting the Right Nitrogen Gas Spring?

To recommend the correct nitrogen gas spring solution, please provide details about your mold setup:

What is the application?
(Metal stamping, plastic injection molding, die forming, etc.)

What stroke length and force rating (tonnage) do you require?

Are you using independent nitrogen gas springs or a connected/manifold system?

BBK-JINGBA technical engineers can help you select the most suitable nitrogen gas spring model based on your mold structure, working conditions, and performance requirements.
