Features of Press Fit Ball Plunger with Flanges
Press Fit Ball Plunger with Flanges Title:
Push Fit Ball Plunger Stainless Steel Ball Spring Plunger with Flanges
Ball Head Plunger Core Feature:
Its core feature is the flange structure, installed at the head or base of the plunger to prevent the plunger from being completely pressed into the hole or accidentally falling off by external forces, ensuring stability and safety.
Commonly used in scenarios that require quick installation and high resistance to vibration, such as mold fixtures or equipment panels.

Ball Plunger Spring Loaded Advantage:
Press Fit installation
Directly press into a non threaded optical hole through interference fit, relying on the frictional force between the outer shell and the hole wall for fixation, suitable for soft substrates such as aluminum, plastic, wood, etc;
Flanges design
The bottom of the plunger has an annular flange to prevent the plunger from completely sinking into the hole when compressed, ensuring that the ball head maintains an effective working height.
Elastic positioning mechanism
The built-in spring allows the ball head to retract under pressure and automatically reset after release, achieving buffering, limiting, or intermittent positioning functions.
Customization Services
Material Combinations: Flexible selection of body, ball, and spring materials；
Dimensions & Parameters: Adjustable body diameter, ball size, and spring force to meet non-standard requirements
Lightweight machinery positioning, electronic product assembly, automation equipment buffering, etc;
Advatage of Spring Ball Plunger :
No welding/no threading design: using Press Fit cold connection technology, directly pressing into the pre machined hole position without welding or threading.
By providing high clamping force through elastic deformation of the ball, the connection stability is maintained even under vibration or impact.
