Krimelte Sealant Applicator

One of Europe's largest sealant manufacturers, Krimelte, is looking to develop an innovative sealant applicator for their standard cartridge. The purpose is to achieve an aesthetic and even seal. Such a perfect seal can hardly be achieved while using sealant applicators available on the market today.

The motivation behind this challenge comes from the simple fact that:

It is extremely difficult to caulk joints without soiling the neighbouring surfaces while achieving a beautiful seam at the same time. Usually this is done by masking the neighbouring surfaces with tape, caulking the joint, removing the excess caulk with a spatula and then removing the protective tape.

However most professionals can apply this caulk in one pass (without tape) by moving the caulking gun with constant speed and applying suitable pressure on the trigger/handle of the gun. It is difficult to achieve for most non-professionals.

We want you to design something simple and handy to use.

One of our first ideas is to use peristaltic pump principle: http://www.youtube.com/watch?v=rPNRwhVcOr8&feature=related

There could be a small wheel(s) running on the surface that regulates the amount of sealant dosed.

Requirements

  • Applicator should be small, compact and easy to use

  • Attaches to standard 310ml caulk cartridge with GL15 thread

  • Typical output 9-15 ml of caulk per running meter

  • Parts in contact with sealant should have easy access for cleaning

  • Parts in contact with sealant should be easily replaceable

  • Applicator needs to function without any power or pneumatic source

  • Must give out even amount of seal without depending on how fast the applicator is actually moving

    I agree with Tobias... do it's possible to get a 3D model of the cartridge? (or at least dimensions)

    Yeah, was just about too ask about that, would be good to know all the sizes of the old product for development of the new. Thats just common sense.

    From my understanding no....you can't Damian ....requirement is I quote: "Applicator needs to function without any power or pneumatic source" that means no electricity....only mechanical...please corect me if i am wrong

    Yeahh... that's of course clear sentence... but comparing to they approach of using the mechanism base on peristaltic pomp idea (which require power supply) I just asked to be sure.

    Hey guys, when I started to model the cartridge I couldn't find any of those in the library (otherwise I wouldn't have done it).
    Two hours later I come back here just to discover other people had the same idea...
    Check it out: <a href="Cartridge _reference_KRIMELTE " rel="nofollow">KRIMELTE cartridge</a>

    Peristaltic pump only works with very liquid fluids, not the case of the sealant.
    Classic push pump is needed here, it only needs a more ergonomic manner of design.

    @Hevi: Thanks a lot!

    @Emil Pop: Check out what wiki tells about peristaltic pumps:
    They are in fact appropriate for thick liquids! The problem is: Is the suction great enough to pull the whole cylinder of liquid? I even thought about having a twin peristaltic pump which pulls the liquid at the tip and presses air in from the back.
    Then I decided to think of something different... Good luck everyone!

    Hi, i have a question, does anyone know the viscosity of the sealant? Part of my design is to hopefully maximize flow rate with minimum driving force.

    Thanks in advance!

  • Meelis Klimov

    Usually the viscositys of sealants fall into a range of 60 000 - 90 000 mPas
