Product Overview
Spring Plungers Steel Screw

The spring plunger is also known as the positioning column, ball screw, spring screw, etc. It is a product involving vertical stroke, in which the front pin is pressed till the pin sinks into the body and then the front pin can be ejected through the built-in spring. It can be used in mold release, workpiece lifting and positioning, etc., which can be widely applied in medium and low-precision mechanical devices, fixtures, molds, automation machines, etc.

Frequently asked question (FAQ)

Question: What role does a ball plunger play?
Answer: It specifies the stroke of the front ball and can be used for temporary positioning and indexing of workpieces.
Question: What role does a spring plunger play?
Answer: With pin-shaped front section, it can be used to eject workpieces or stoppers.
Question: What is the difference between a ball plunger and a spring plunger?
Answer: A plunger is headed with a steel ball and its stroke is the displacement of the ball. A spring plunger has a pin-shaped front section and the displacement stroke of the pin is used for such purposes as temporary positioning and indexing of workpieces.
