  • System for twin sheet forming
    Patent number: 6659758
    Abstract: A twin sheet forming system and method is used to form a hollow article, such as an automotive fuel tank, from first and second sheets of thermoplastic material. The system includes first and second loading stations, first and second heating stations, and first and second thermoforming stations in an in-line arrangement. The in-line arrangement allows the sheets to be transferred independently between the stations and the separate thermoforming stations allows the sheets to be thermoformed independently. Each of the thermoforming stations includes an upper and lower platen generally in a side by side arrangement for supporting thermoforming tools and plug assists. After heating, the sheets are independently transferred to the thermoforming stations and formed using the thermoforming tools and plug assists. The thermoforming tool and thermoformed piece in one of the thermoforming stations is then transferred to the other station, and the thermoformed pieces are fused together.
