Heat sealing barsCIRUS
ROPEX offers various possible options for realizing your heat sealing application: in addition to a wide range of standard bars in several different versions, we can also manufacture customized tools tailored to your specific requirements if these bars are not suited for the job. ROPEX sealing tools can be protected against cleaners, for example, or against corrosive or aggressive media (IP65 protection, FS technology), particularly for packaging tasks where tool or machine cleaning and hygiene are paramount. No matter whether you choose our standard bars or customized tools, they must be combined with a matching counter bar in your heat sealing application.
All of our tools – both standard and tailored to your individual requirements – can be supplied as 3D CAD models or with 2D installation drawings on request.
Standard UPT heat sealing bars
FS bars are heat sealing bars for use in damp or corrosive conditions, for instance if the machine has to be regularly cleaned with water or a liquid detergent. These bars are also suitable if the product to be packed is itself corrosive (e.g. saline solutions, fruit juices etc.). A special coating and the hermetically sealed contact area ensure compliance with the IP65 protection rating. FS bars are shipped with heating line lengths from 100 mm to 500 mm in 50 mm steps. They can also be supplied with heating line lengths from 500 mm to a maximum of 1000 mm in 100 mm steps. Heating line widths of 2.8 mm, 4.8 mm and 6.0 mm are available as standard.
FS bars have 1.5 m long cables at the contact area owing to the design. All of the above-mentioned heating line length and width combinations are offered with three different cable outlets for easier integration into the machine:
- D: The cable exits vertically downward
- S: The cable exits perpendicularly at the side
- L: The cable exits as an extension of the heating line
Standard GW bars are UPT heat sealing bars for use in normal conditions, in other words neither damp nor corrosive. These bars are shipped with heating line lengths from 100 mm to 500 mm in 50 mm steps. They can also be supplied with heating line lengths from 500 mm to a maximum of 1000 mm in 100 mm steps. Heating line widths of 2.8 mm, 4.8 mm and 6.0 mm are available as standard.
Precise guiding and fixation of the film are just as important for a high quality heat seal as accurate and repeatable temperature control. ROPEX offers various complementary components for this purpose which interact optimally with the sealing tool. Please don’t hesitate to ask for more information.
Our sealing tools can also be manufactured as customized solutions tailored to the individual requirements of your sealing application. Close cooperation and coordination with our customers are very important to us: your tools are designed and built on our CAD system according to the specific parameters of your heat sealing process and the space which is available in the machine. Special temperature profiles as well as overlapping and / or individually controllable heating lines are possible, and we can also realize any desired heating line geometry.
