I'm working on the design of a plastic part that will be painted black in a matt finish. What should I specify for the surface finish? SPI C-1? The reason it being painted is because its a backlit display panel so it will need to be translucent to carry light to text and graphics. Clear part...
I'm working on the design of a control panel that goes in a vehicle that is approximately 6" square with the front face having a 2" by 6" area being flat that will be an arms reach from the operator. The part is going to be injection molded. On the reverse side of the flat area there are...
I played around with a demo version of David Laser Scanner using a cheap webcam and a projector a few years ago I was using a really cheap webcam so the results were not that great but looked promising. I have an upcoming project where I need to make a design work with an existing product. I...
Hi,
I'm working on a consumer device with a small rechargeable battery. I have just enough space for a micro usb/usb c connector. I would like to use a magnetic detachable connection. Rather than coming up with something from scratch does anyone know of any open format designs with a similar...
I'm finishing up a design for a consumer product that someone else started. Can't share the specific details unfortunately. I have a nylon part that has a 35mmx49mm footprint with a radial brim flush with the bottom that sticks out 1mm and is 4mm tall (from the bottom). All the corners have a...
I am working on a product that is currently using a normally open normally closed [edited] reed switch that when a magnetic field is present turns on off [edited] a small LED. I was told other types of sensors like a hall effect sensor was looked into but the longest battery life that could be...
I am looking for some recommendations for an electrical contact material.
I am basically picking a design change from prototype to production where someone else left off. I am re-designing a small sheet metal part that needs to also function as a spring to keep electrical contact with a watch...
Hi All,
A bit of background first to better give context to the nature of my questions. I have a BS degree in AE and have worked in the corporate world in different engineering positions for 4 years but never did anything with drawings. I now have my own small business and do machine work...
I'm looking at making some prototype powdered metal parts in house which is something I do not have experience with. I'm looking at doing some research on different solid lubricant add mixtures to powdered metal parts which is the reason I am not just having this farmed out. The part is a simple...
Hi,
I am developing an automotive cylinder head for which I am doing all the foundry work for the prototype. I am having some pretty serous issues with core blows mainly from the water jacket. I have developed casting experience/processes which I have used to produce other simpler, cored...
I am working on a design that uses a ball valve type sealing device to seal hot gasses resulting from hydrocarbon combustion (diesel/gasoline w/air). The first prototype I used bronze for the seal and 6061 for the ball. This worked for a proof of concept for the overall design but as expected...
