  • Hot air cold form staking device
    Patent number: 5423938
    Abstract: A hot air cold form pin welding device for use in assembly of work pieces using thermoformable and pressure deformable synthetic resin studs. A hot air heater is positioned in a support structure that isolates heat transfer along with multiple power and air cycling to reduce heat build-up. The cold forming pin assembly with internal heat dissipation and airflow structure forms and presses a replasticized pin significantly reducing the cold pin press cycle time.
