    Identifying a transistor part mark

    Have a part I am trying to identify, SOT23-5, labelled QWA6. Assuming it is a transistor, could be a diode in this circuit. Cant find it.

    laser welding plastic, and laser soldering

    We have a couple of product problems that may be solved with a laser. First problem is to seal a glass lens into a delrin lens base: we can make a small bezel which overhangs the lens and laser or hot-stamp it to act as (hopefully) a seal or at minimum a means of clamping the lens in place...

    Guidance on Epoxy molds

    We have purchased an Arburg ALlrounder 35 ton injection machine, old but in beautiful shape. It has a MUD set (modular tool setup) so quick change with smaller subtools make this ideal for us. What I want to do is make a unit tool (basically a bath-tub for the epoxy) for epoxy molds. We do a lot...

    best way to convert 400 VAC environmental chamber to 480 VAC

    I am considering purchase of an evironmental chamber that is 400 VAC 50 hz. I have 208 and 480 VAC in the shop. The chamber basically is an oven and a refrigerator, so lots of stuff including control electronics. If it was a simple device the 400/50 matches up with 480/60hz, but it is not so...

    brass insert pull-out in Lexan

    Recieved a large delivery of Lexan parts that fail in torque test. There is a small threaded brass insert molded into the housing. The insert acts as a captive nut in the housing, and the housing is clamped onto a mounting bar. This normally takes foot pounds, this shipment didnt even take 10...

    overmolding glass

    I have a sensor which is a small delrin cylinder, to the end of which a small lens is adhered. I am contemplating an insert mold where we incorporate the lens into the body. The reason is to guarantee that the lens stays there over the lifetime of the product. We are currently using a custom...

    hot stamping delrin

    Perhaps a classic situation: I have 500 delrin housings with a small set of molded-in initials of an ex-client. This was done as a courtesy, and of course the rest is history, as is the client. Our parts and tooling by the way. So being cheap enough not to scrap some good housings, I am looking...

    small but precise mill

    I need to drill two 0.050 inch holes in stainless steel. The part is effectively a 1/16 npt bolt, which has been hollowed out. The hex head end has a circular recess 1/4 inch in diameter, and in that recess I need to drill the two holes. They need to be placed accurately, within 0.001 inches...

    condensing gasoline vapor

    I have to drop the temp of a fuel vapor stream (continuous)to condense the vapor. Input temperature of the stream will be about 4 deg C, modestly dehumidified. Flow rate is variable, but 30-40 liters/minute max. What size compressor and how should I configure this unit? (apologies for my...

    glass lens to metal base

    I make environmental sensors. I need to hermetically seal a glass (BK7) lens to a small metal base. Base can be aluminum, stainless etc. Lens looks like a bowler hat, 1/4 inch in diameter, and I would make the seal on the outer edge. We have a complete smt facility so I can screen and reflow if...

    Plastic Injection: In-house or out-house?

    I write this attempting to limit any pre-prejudices. I have the option of bringing in a small electric plastic injection machine, 33 ton, 1 oz shot, about 8 yrs old. It would cost me less than a new proto machine for the lab. With this we would be a rare fish: vertically integrated (we make...

    manual for Sony Cast-AU

    Looking for the manual for SONY Cast-AU x-y-z "desktop" robot. The AU is the screwdriver application, we have most things sorted out, but it would be helpful. Also looking to buy a controller for the Delvo screwdriver that is with this machine - this would be a controller for an automation...

    SS diaphragms for pressure sensors

    We are developing a small line of specialty pressure sensors. These are relatively small, and the diameters will be 2mm for one model, going up to 12mm for the largest. We are now at the tough part and thats designing a good diaphragm, and am looking for help. We can source the diaphragms or...

    cleaning Lexan parts

    We have a few thousand devices out in the field with bodies made with Lexan. At a couple of large installations we found the client with metal housings around the devices - because "they were getting hit". Comes out they have bee routinely spraying with cleansers of various types, effectively...

    FeedBack on recommissioning Staublis

    I would like to thank everyone who has chipped in on this effort. We have all of the machines up and running, now to End Effector school! Our primarry problem was power. The manuals show the same circuit for power programming the transformer taps - bottom line is you might have a "400-ish"...

    Staubli recomissioning

    Can anyone recommend a good repair service / recommissioning company for Staublis? We are doing a good job in recsucitating our new (used) Staubli RX60s, but I am afraid we may be hitting a wall soon. We have E-stops cured, and have a panel made up which we think is "answering" a lot of...

    firing up a Staubli rx60

    We have just acquired a used Staubli 6 axis robot. No manual, but one is one the way. We deduced that the system was either 480 or 240, and with the connectors rated at 400volts, I figured 240 was the good guess. With 240 vac the controller electronics side powered on with various error lights...
