Hello Pat, Yes, the 6TONS are very small presses, but with the small intricate parts (low cavitation 1-4) we do they have seemed to work pretty good. Also, dimensional stability is critical for our applications. Normal tolerances are ±0.05-0.10mm. 1. The projected area for one of our parts is...

Does anyone on this board have experience with 6TON presses? We are implementing them for some of our product lines and are running into some minor problems. One of which is that we are constantly getting parting line flash 180° of the gate location. These are very small parts, about the...

If the polystyrene softens & swells while it is in the silicone will it absorb the silicone and then retain that swollen state once it has cooled, or even at RT? What will happen in colder temperatures? Is the rate of expansion faster than that of the silicones dropping viscosity?

We are planning to use the particles in a Silicone solution to reduce the effect of temperature changes on the material. We use the silicone in a rotational damping application. Our torque of the damper is greatly affected by temperatures from -40C to 90C. We have experimented with custom...

Hello all, I was assigned a new project here at work and it involves the use of Polystyrene Particles in the 5-6 micron sizes. Does anyone have any experiance with these? I know absolutely nothing about them, so any information is useful.

Hello all, I am planning on constructing a test setup for work that would involve the use of a rotational electric motor to turn various small gear dampers. This test would be used to test accelerated life testing and would rotate the small gear dampers (which are the size of about a quarter) in...

What is a .cgr file? Is it like a 3D surfaces file similar to an IGES file only cleaner? Their IT department were the ones to make the decision and they want 3D solids in native Catia format only. *.model only. Unfortunately there isn't any room for negotiation right now, we tried that. Chad

We tried that for a while and it worked fine. We were sending them STEP 203 files but they then decided that they were only going to accept CATIA V4 files. Any translation that we need to do is our cost of doing business with them. Fortunately we do enough business that we can justify the...

Unfortunately with some of our customers it is the other way around. Most of our customers are pretty reasonable, but some are very adamant about what file types they will accept or they will go elsewhere with their business... Chad

Hello, We are an automotive supplier trying to find a 3D translation software that will accomodate all of our customers and have not had much luck searching. We currently use SolidWorks to do all of our 3D design. We have customers who are sending us 3D in a variety of formats which they feel...

Does anyone on here know what the soloflex rubber bands are made out of? I am assuming it is a type of rubber and after looking at a couple I am thinking that it is compression molded. We have a project and think that something similar to one of those rubber bands would work for it. I have...

hello, I currently have a project which deals with an injection molding process at work. We are molding pairs of brackets in a 4 cavity mold. 2 of the cavities are the RH bracket and the other 2 cavities are the LH. Currently we have a robotic arm with 2 grippers which comes down in from...

After playing with some "low-temp" pneumatic cylinders and having little success I think we are ready to redesign our testing fixture to adapt a 90° gearmotor to the fixture. I have run through some quick calculations. The -40°C operating torque of our parts is 28 oz-in. With 16 parts...

The silicone is a fluid which is used for damping purposes. We use silicones with many different viscosities which range from 10,000 to 1,000,000 centistokes. What I am looking for in the pump is the ability to dispense very small controlled amounts of silicone (0.08±0.001g) repeatedly. This...

Our parts fit into the round recesses in the green bars and engage with the gear teeth on the sliding table.

Currently we are searching for a positive displacement pump which can dispense small amounts of silicone. Currently our smallest shot weight of silicone is 0.08g ±0.001. This equipment would be used for custom part samples, as our standard parts are assembled in a fully automated machine. We...

Thanks to all who have given suggestions. I have been in contact with a few companies regarding this issue and hopefully we will be able to get something to work for us. Jsummerfield: I don't think that spring loaded pneumatic actuators would work in this situation since they are dual acting...

The cylinder has air plumbed to each end. Line 1 pushes the cylinder in the forward direction. Line 2 pushes the cylinder in the reverse direction. What type of valves are your currently using, and where does the air air from one side of the cylinder go when you are pushing the other way...
