Impingement Mix Gun

The key to good quality foam and trouble-free operation is the utilization of a manageable yet robust and ergonomically compliant applicator gun.

Since 1991, Jesco has been developing and improving the patented Autofoam Dispense Systems and two component mix guns for a variety of chemistries that have been successfully qualified for production. The balances of temperature and injection techniques, as well as pressure control and actuation response are the key elements in Jesco's success. Whether automated or manual application, the gun has to be articulated in order to fill the appropriate cavity. Pistol and parallel grip styles were designed to facilitate versatility.

Vehicle Noise Reduction Challenge Met

The first major installation was at an automotive assembly plant in May 1998. The assignment was to inject foam into 24 locations within a vehicle to provide noise reduction. Three operators were assigned to each side of the line. The plant was to run three shifts per day, six days a week.

Jesco stepped up to the challenge and provided a robust production dispense cell meeting the automotive manufacturer's expectations. All runoff criteria was performed at Jesco's research and development facility in conjunction with the automotive manufacturer's personnel.

News of Success Gets Around...

Based on the success of the Autofoam Dispense System's performance, other automotive plants were intrigued enough to want Jesco to set up systems for their plant operations. Each foaming system proved to be a positive performer.

Full system interface including F.I.S., PFCS and AVI systems provided vehicle tracking and repair notification. These are among a few of the features utilized by the various plants. An entire hose management system (as seen in the upper photo) was also furnished. Sound deadening qualities are a key feature with automotive designers as well as the consumer.

Jesco has taken an active role in providing cutting edge equipment solutions to the automotive industry. Jesco now has acoustical foam dispensing equipment in over 10 locations including lab and production environments. Jesco is ready to take on your foaming challenge.
