    Translucent/transparent higher strength plastic?

    I might be able to increase the thickness slightly but I think I would have problems if I went thicker than 1/8". I don't know how important cost is at this point as it is in a concept phase. Molding would be preferred, but machining would be entertained.

    Translucent/transparent higher strength plastic?

    I only need to transmit UV through it once in order to cure a resin product.

    Translucent/transparent higher strength plastic?

    I need to be able to transmit UV through the material. I don't think stiffness will be required as long as the material won't yield under load.

    Translucent/transparent higher strength plastic?

    I'm looking for a translucent/transparent plastic that mimics either a low carbon steel (1010, 1018, etc) or stainless steel (301 or 304) in terms of mechanical properties. It will be part of a mechanical joint; therefore, yield strength is probably the most important factor. It will be...

    Elastomer vs. Foam

    The material would be applied in the factory.

    Elastomer vs. Foam

    Does anyone have information on why one would choose an elastomer over foam for an application, other than price? I have an application that I have been looking to use either a silicone or urethane foam-in-place gasket, but the thought of an elastomer hadn't really crossed my mind until...

    Stud welding information?

    Does anyone have a recommendation on a resource for stud welding? Book? Training course? Direct contact? I'm new to capacitance discharge welding and am trying to design a weld stud. I am also trying to understand what parameters are involved in the process.

    Liquid foam gasket

    Thank you for the link! The end product is a variety of products that are used in home improvement/DIY/construction products. Examples: windows, sinks, faucets, doors, etc. I am looking to replace silicone caulk with a foam gasket that can be applied in the form of a liquid. The silicone...

    Liquid foam gasket

    I'm looking for a liquid that can be dispensed onto a stainless steel product that will "solidify" into a foam gasket. The finished height of the gasket would need to be approximately 0.25". The application equipment would be a dispensing system put on the end of a robot or cartesian system...

    Keyhole fastener?

    Thanks mog69 for the response! Unfortunately after reviewing the Dzus website it is not the quarter turn fastner that you are referring to. I'll try to describe it in more detail. The "female" component is a piece of flat stock with a keyhole punched into it. For discussion sake let's say...

    Keyhole fastener?

    I am trying to find information on a keyhole type connection that I remember seeing somewhere but can't find. It is a simple stud to keyhole design but it uses a piece of spring steel on the keyhole side of the connection to "lock" it in place once it is slid over the stud. Can anyone help me...

    Fast fixture time for structural adhesive?

    We have only been able to find one product to work and that is a two part acrylic from 3M. We have tried Devcon and Loctite products but they have failed up to this point. The adhesives typically fail the humidity testing where we cycle between -35 deg F and 95/95 humidity for 5 days. Each...

    Fast fixture time for structural adhesive?

    Thank you for your replies! We are looking to replace spot welding. It needs to only hold 0.01 lbs within 5-6 seconds. Once the adhesive is cured (many of the adhesives I have found have a 24 hour cure time) it will then be subjected to the load and atmosphere I reference above.

    Replace clamping with secondary adhesive?

    Has anyone ever tried or do you have ideas on ways to replace clamping with a pressure sensitive adhesive? I understand that clamping actually applies a force where an adhesive would simply hold the components in place, but would this be enough? I was thinking of applying the secondary...

    Fast fixture time for structural adhesive?

    Thank you for your comments and ideas! This has been a particularly tough application for us so I appreciate your patience and creativity. Would the hot melt be strong enough? To give you a better idea of the design there would be a 100 lbs of force being applied in shear to the 0.5" x 0.5"...
