    Need to Design a Paste Lubricant Applicator Device...Parts and Methods?

    Thanks for the tips! I like all the ideas, but the lubricate is applied more like a polish where it's rubbed into/onto the surface and has a thick paste type viscosity; significantly more than bearing grease, for example. When we apply by hand, we rub the paste into the surface leaving no...

    Need to Design a Paste Lubricant Applicator Device...Parts and Methods?

    Thanks for the reply. That's a great start...I'm concerned that my lubricant is quite thick and does not have the same viscosity as oils. This paste lubricant won't necessarily wick through those bristles found in the grease applicators. I'm wondering if there's a way I can mist or spray the...

    Need to Design a Paste Lubricant Applicator Device...Parts and Methods?

    Hi Everyone, I made a post in the finishing sub-forum, but I think it does not get enough traffic, so I thought I'd share the link here: http://www.eng-tips.com/viewthread.cfm?qid=357994 Your thoughts or advice would be greatly appreciated. I'm really looking for the best way to apply the...

    Need to Design a Simple Machine to Apply a Paste Lubricant to a surface

    Hi Guys, I hope this is the correct place to make this post. We have some parts that need a lubricant applied to the edges of a part. Since volume is increasing, applying by hand is tiresome, slow, and inconsistent. For simplicity sake, Imagine a 6" x 6" x .25" plate. One the 6x6" surfaces...

    Parameters and logical operators

    Can totally be done, but within a RULE. You need a Knowledgeware Rule made from the knowledgeware advisor workbench. Stick whatever parameters you want inside the curly brackets. See Image Example:

    Design - Need to attach a cap to end of metal tube

    It's a consumer product and it's a housing for electrical components. No extreme temperatures. 0F-100F. It shouldn't be too easy to open either. It would only open for major service and of course assembly. Tube is metal(steel or alum extrusion(I'm leaning towards extrusion as I can design...

    Design - Need to attach a cap to end of metal tube

    Hello, I am looking for a way to attach a cap to the end of a tube and looking for some suggestions. The tube is Appx. 3" OD tube with .06" wall. The cap also has an OD of 3". Threading the cap on with internal threads into the tube is not an option. I'm looking for some more unique ways to...

    Best Way to Remove Knife Edge from Molded Parts

    Flaming the parts is still an option to try. Is there a fixture/setup/guidelines/temperatures on how to do it properly? I tried some deburring tools and they did not yield consistent results. Sometimes the blade will really dig into the edge and gouge it., but a B-70 style looks promising.

    Best Way to Remove Knife Edge from Molded Parts

    We actually discussed routing the parts, but that would be too costly at this stage. Will keep that in mind. Pat, yes, it kinda is! We will try adding the fillet to the flat side on our next parts. Like .010" rad. For now, looking forward to results of the safety knife. Thanks

    Best Way to Remove Knife Edge from Molded Parts

    It's easier to show with a shot from the 3D model. I've highlighted the edge that needs to have the edge rounded over slightly. There is minimal, if any, flash on the parts coming from the mold. I understand that we could have put a radii on the part and then shift the parting line up...

    Best Way to Remove Knife Edge from Molded Parts

    Thanks, but it's more than just flash. The actual flash is very minimal and can actually be removed with a finger nail. The molding facility wanted to avoid knives if possible. The part itself has a sharp edge around it's perimeter which coincides with the parting line. It's the part geometry.

    Best Way to Remove Knife Edge from Molded Parts

    Hey Gurus, I'm doing a production run of some glass-filled PP parts. I'm getting a knife edge at the parting line that needs to be polished down to a small chamfer/fillet. Due to the geometry,schedule, and cost, we cannot change the mold. Is there any special abrasives that will not leave any...

    High Volume Resin Transfer Molding Process

    Will be using Foam-Filled Honeycomb.

    High Volume Resin Transfer Molding Process

    I've been researching and I'm looking to see if there any alternative processes to RTM that yield the same type of parts, but with low-cost and high-volume capabilities. Specifically multi-layered composites with and without a honeycomb core. The parts are smaller; roughly 6" x 6" x...

    Struct Analysis: Holes/features ignored/not being meshed (pic)

    Alpha, You can use your existing assembly constraints to make the connections in your Assembly Analysis. Use the "Connection Properties" toolbox. Without seeing more of your assembly, I'd start there and play around. You can also find some decent resources from google.

    Multi-selecting items

    There are several ways. You can graphically select them in your model by holding control button while clicking on them. You can also graphically pick them from the graph tree while holding the control button down and clicking the items you want. Alternatively, you can use the search tool to...

    Complex Surfacing Fin/Skeg shape.

    I'm referencing an old thread I started about modeling a fin... thread560-210022 Update: I'm developing some fins and some have been scanned via reverse engineering processes. I'm having the same predicament about modeling the tip. I couldn't really figure out the last bit described in the...

    Struct Analysis: Holes/features ignored/not being meshed (pic)

    I found my problem. My part body had an "extra" pad at the bottom of the partbody tree. It was the original entire profile which made my part hole-less again. In part design, the feature just above this ghost pad was the "work in object". I deleted the pad and viola! Sorry to waste space on the...

    Struct Analysis: Holes/features ignored/not being meshed (pic)

    I have an assembly that I am meshing and for some reason these holes won't mesh on a specific part. Also some counterbores on some holes aren't meshing either. I've tried different things, like local mesh size and I cannot even choose the inside hole surface. No luck here. Any insight or tips...

    using " IF " and "ELSE" to dictate parameters

    Yes, you'll need Knowldgeware Advisor to get the if/else rules and whatnot.
