HOW IT WORKS
Impulse Staking is a process that creates heat on-demand for plastic staking bosses of all shapes and sizes. The patent-pending technology of Impulse Staking makes it the most efficient and ideal process for sensitive electronics and parts that are susceptible to excessive heating and pressure damage.
Instead of having to wait for the tips to cool at the end of each cycle, Impulse Staking allows instantaneous cooling to room temperature within seconds. This prevents any accidental injury while eliminating the need for constant heating.
During the Impulse Staking process, a solid or hollow boss or tab protruding through a mated part is heated to a softening temperature and formed to a head that captures the mated part.
Unlike heat staking and ultrasonic welding, Impulse Staking applies a significantly lesser amount of pressure on the mated part providing a clean and string-free method of staking.
Our patent pending Impulse Staking technology is a proven process for a cost-effective solution with little to no maintenance.
Parts are loaded into the fixture which senses for presence. The operator then presses the cycle to start. The platen descends, and all tips make contact with the corresponding plastic boss. Power is pulsed to the tip creating heat at the boss and tip interface. The heat melts the boss and begins to form the button.
Once the heating cycle is complete and the tip is fully extended, a blast of compressed air enters the air tube and blows onto the back side of the tip venting through the visible slots. This allows the welded button to cool and form a strong bond with the mated part.
Now that the button is cool, a short pulse of power is applied to the tip to whet the surface of the plastic. This CleanRelease stage prevents any sticking and stringing from happening which is commonly seen with other methods of staking. The welding is complete with a strong and lasting mechanical bond.
