VMI provides a wide range of airspring building machines and tooling suitable for the production of several types of airsprings complete with a flexible level of automation. Single stage or one process systems are available for the assembly of cylindrical types in one step whilst the two stage systems enable the building of conical airsprings or types with different bead sizes.
The mechanical turn-up technology and accurate component preparation is based on the same technology used in VMI's proven tire assembly systems.
Single stage airspring building machines
This machine builds the automatically pre-cut carcass layers, sets both beads with equal diameter, performs the mechanical turn-up and handles the stitching procedure. It is also used as a first stage machine for conical airsprings.
The picture shows VMI's airspring building machine for cylindrical sleeves.
First stage airspring building machines
This machine builds cylindrical and conical sleeves from the automatically pre-cut carcass layers. In some constructions the smallest bead can be set plus the mechanical turn-up can be carried out followed by the stitching procedure. Beads with a larger diameter should be placed on a separate second stage machine.
The picture shows the airspring building machine for conical sleeves.
Second stage airspring building machines
This machine receives the sleeves from the first stage building machine and depending on the sleeve construction, either a one or two beads setting can be used followed by the mechanical turn-up and stitching procedure. The left and right beads can differ in diameter.
