Correctly installed sprung cores (following our catalogue installation instructions) can produce more than 1 million parts.
The maximum working temperature is 150°C (302°F).
Balinit C is the best coating to apply to our Sprung Cores. It provides a high superficial hardness and a low friction coefficient, i.e., it protects the part and makes it slide smoothly.
The opening of the sprung cores is a radial movement. Due to this, at the edge of the stroke, the opening is 2.5mm (0.098”). Here you can see a more detailed technical explanation.
Yes, it is very important to give draft on the undercut, for the PF => 5º.
The radius of 0.10mm, as minimum, has to be kept in the upper surface if it is grinded or machined.
The radius of 0.10mm, as minimum, has to be kept in the upper surface if it is grinded or machined.
Yes, a deviation up to 0,3mm is completely normal as the material is sprung steel and has elastic memory. The part will function correctly as the deviation will settle once the part is installed in its housing.

Welding is not recommended on any of the sprung core products. Welding exposes them to high temperatures which can affect the treated areas, and therefore the characteristics of the spring steel.
