Frequently asked question (FAQ)

Question: What role does a spring plunger play?
Answer: By controlling the screw-in depth for threads, it enables the internal pin to set the preload and perform up and down stroke movement. It is suitable for mechanical devices, fixtures, molds, automated machinery, etc.
Question: What is the meaning of max load and min load?
Answer: It refers to the load of the product. The min load represents the initial load value, and the max load represents the load value at the maximum press-in stroke.
Question: What is the difference between a ball plunger and a spring plunger?
Answer: A ball 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, mold demoulding and workpiece lifting.
