For applications with high required forces (and therefore very high inflating pressure), Pronal offers 7 bars inflating pressure bags
Made from rubber coated fabric and vulcanized under vacuum in an autoclave, the Pronal HP bags could be inflated up to 7 bar while remaining relatively thin (18mm). The vulcanization process makes the final product homogeneous and guarantees a long lifetime. (more than 10 years in some cases)
- UV resistance
- Ozone resistance
In option, Pronal can propose:
- FDA rubber coating
- EPDM coating
- High resistance temperature coating (up to 140°C)
- Dimensions restrictions:
- Square models : 2500 * 2500 mm
- Rectangular models : 5500 * 2500
- Circular models : Ø 2500 mm
Because of the assembly process, a “dead area” (= no inflation zone) will be located all around the bag. This dead area has to be deducted from the surface of the bag before calculation of the applicable force.
The inflation stem can be placed on the face or the edge. If on the edge, a short tube of copper with a quick connect coupler at the end will be provided; or an integrated steel insert where a stem will be mounted.
Note : The inflation stem located on the edge will increase the “dead area” dimensions.
Pronal can manufacture several bag shapes such as:
Max 3 stages (K1 = square 1 stage / K2 = square 2 stages/ K3 = square 3 stages …)
Other shapes upon request.
- Lifting bag tensioner
- To lift and move a load
- To maintain parts during a vulcanization process
- Tipping over a bucket
- Clamping complex shaped parts
