Hello,
I've been having a product manufactured in China for about 1 year, and currently we have a 3rd party do an Final Random Inspection on ~7.5% of the 1st completed container of the build. So far the quality has been good and we haven't had any major issues, but this process doesn't allow us...
Hello,
I'm recently had a few shear failures for a turned brass H59 part (see the link below for an image). My gut tells me that it's a material defect, since we've made over 10k of these prior and only just started seeing this failure mode. Does this make sense? Has anyone seen this before...
Hello, I was hoping someone could tell me how Dyson achieves the look of the attached plastic part. Is it an in-mold label? I would appreciate any feedback you have!https://files.engineering.com/getfile.aspx?folder=5f4f404a-e737-496c-8e3f-fa4f80ced4d5&file=dyson_pic1.JPG
Apologies, I am in the US and looking for low-cost vendors for these 2 processes.
As for process details, I need pressure diecasting, and the extrusions are a mix of custom profiles and off-the-shelf cut-to-length.
I hope this clears everything up!
Hello,
I'm working through my supply chain for a new product I'm working on, and my old overseas vendors for diecasting and metal extrusions have dried up. Does anyone have any recommendations for good foreign vendors for these two fabrication methods? I would really appreciate any...
Hello, I'm trying to see if I can avoid plating a plastic component I have by using a resin color that looks metallic. I've seen this on products before, but I don't know where to look to find these types of colors/processing parameters. Does anyone have any advice? Thanks!
Has anyone had success with chrome plating on 2 plastic (ABS plating grade) parts that have been ultrasonically welded together? I received DFM feedback from 1 vendor that said they thought there would be discoloration around the seam due to an inability to properly clean that area. I would...
Hello, I recently was wondering how the crevice tool attachment of my vacuum is made (see picture link below). It has a long internal cavity with minimal to no draft. The only thing I can think of is that it's either made in 2 halves and then ultrasonically welded, or it utilizes a collapsible...
drawoh,
Thanks for your response! I'm avoiding fasteners for aesthetic reasons. The parts aren't finalized yet, and won't be fully mirrored. I definitely haven't ruled out glue, but is there any reason you wouldn't use an interference fit to mate the halves? I was thinking of bosses for...
Hello, I'm looking to join 2 mirrored diecast parts. Basically, I'm looking for the equivalent to ultrasonic welding for diecasting. Does anyone know the best practice to achieve this? The materials I'm considering are AL or a Zinc AL alloy (Z8). I would appreciate any advice, thanks!
Hello, I'm designing an ABS plastic part that's going to experience a constant load (see image link below). I'm concerned that the surface under load will creep over time. If this surface deflects too much or breaks, then this could cause failure of the product. I can't seem to find creep...
Hello, I'm an ME of 14 years, but have only worked on electromechanical consumer products, and haven't work with fluids. I working on a project now that requires me to design a 3 way valve for a shower application, and I was hoping to find some design guide recommendations. Any help would be...
Does anyone have experience using ultrasonic vibrations to help remove water from a surface? I know water can be atomized with ultrasonic vibrations (e.g. ultrasonic humidifier), but that produces cavitation, and would damage the surface involved. Would higher frequencies still help to remove...
