    Foaming adhesives, edge closeouts

    I am looking for an extrudable foaming epoxy adhesive. Extrudable in this case meaning it has low enough viscosity to be pumped or injected with a pneumatic applicator. Our application would be "net molded" parts, where a composite honeycomb panel (2 ply prepreg/core/2 ply prepreg) ejects...

    Blind Fasteners

    The ball stud concept could work, but we run into fastening issues with not having access to the back side of the wall. We could pot inserts (see NAS1836, etc..) into the wall but then run into leter coverage issues. The letters need to cover all the fasteners. What about some type of...

    How much resin do I need for a simple injection moulded extrusion?

    I am looking for some multiplier to help ensure I request the proper amount of resin for a part run. The material has various colorants added. I have the crossectional area of the part/die and I know the length of my extrusion. With this I can calculate the volume of plastic making up my...
