Plastic Assembly Systems’ invention of the STS2000 (servo thermal system) heat-staker revolutionized machine control, giving users unprecedented levels of efficiency when heat staking or assembling plastic parts with inserts!

Innovating Plastic Assembly

Our mission to enhance your plastic assembly experience goes far beyond harnessing the power of servo technology. For instance, we introduced machine features like our PAS designed Jig-Binary. This allows our STS2000 and other assembly systems to recognize tooling changes and automatically load the program parameters associated with the installed tooling. Simply put, we eliminated tooling set-up errors entirely! 

Network Connected Machinery, Cutting Edge Customer Support 

To better assist our customers, we offer network relay installation in our systems. Allowing us to provide premium customer support, troubleshooting your PAS system remotely from our Connecticut headquarters.

Designing Forward Thinking Equipment

We designed the only hand-held heat staker of its kind on the market. Giving users a dedicated assembly solution when they believed their only option was a frustrating to use soldiering iron! The PAS hand-held heat staking station has been critical for countless low volume production runs and lab testing applications.

Advancing Spin Welding Equipment

Beyond staking and insertion, our SW line of spin welding machines assemble circular thermoplastic parts with ease. These servo driven, energy efficient units produce frictional heat through rotations up to 6000 RPM, creating a bond stronger than your parent material. Presenting users with control of both the spin and z-axis, the SW series of spin welding machines has hermetically sealed countless circular joints!

Harnessing Hot Plate and Vibration Welding

Our knowledge of plastic joining methods goes far beyond heat staking and spin welding. We have developed complex custom systems harnessing hot plate and vibration welding technology. There is no thermoplastic assembly too complex or nuanced for the team at Plastic Assembly Systems.
