The type of staking that involves melting a piece of plastic to hold two parts together in an assembly is called heat staking. During this process, the plastic boss is heated to a temperature where the boss melts and pressure is applied, then the boss is cooled down to form the bond. This process is low in cost compared to welding and other joint-making techniques. It can also be used in various industries because it offers the possibility of working on huge volumes in a cost-efficient manner.
Staking is a good solution to avoid vibrations and stress cracks. It can also be a way to avoid using additional hardware to prevent possible quality control issues due to defects. Even more so than other methods, it benefits manufacturers because the whole process of combining materials is finished in a single cycle time. This process uses the same base material throughout, has more pull strength, and doesn’t cause any mechanical stress. There are various methods of heat staking. To only name a few: hot tool staking, hot air staking, ultrasonic, and focused infrared energy.
The process of heat staking is used for various applications. It ranges from joining automobile panels to medical equipment to packaging, and more. In this blog post, we will turn the spotlight on two innovative heat Staking methods designed by Extol. The InfraStake and the Nanostake are, as mentioned, innovative technologies with the ability to stake in tight and delicate spaces.
