UBE started off as a coal mining company. Now they do a little of everything. UBE city in Japan is basically an area the size of a city for all the UBE facilities. I heard they have 200,000 employees.
>>>Buying an extra machine just for spare parts??? Yikes!!! Have you calculated potential down-time to replace said spare parts when the 2 running machines break down? <<<
This was just management coming up with "bright" ideas to saving money. I already got them steered away from that idea...
The sales guy said the servo motor will usually last the life of the machine. Same as with the toggle mechanism. Does that sound feasible? Our old ram cincinnati machines have gone through several motors.
Patprimmer: How is it that you know so much about automotive technology and injection molding equipement? I only dabble in automotive. You seem to be more of an expert.
I think the JSW is a good machine too. I got a quote on that as well. The cost is pretty high ($470,000) so I think...
I think it was the JSW that I was thinking about that have gone all electric. I also have quotes for JSW. Any thoughts on those?
I will have to find a sales guy for Arburg. I am not very familiar with the Arburg brand. I usually only see them in small tonnage machines. .....I just looked...
I have used an older battenfield in the past and an older Engel. I have also gone through the screens on a newer Engel. I am not impressed with the controller on any of the European machines I've seen. They are always more confusing than they need to be. I like a simple screen that anyone...
Thanks for your reply. I'm glad you brought up the oil temperature question. I will ask about that.
I have no experience with Arburgs. Some molders around here use them. Aren't they all electric now?
I am looking at buying 2 new 700T-800T molding machines with new robots. I have a few choices that I would like to get opinions on. They are in order of what I like the best based on operator interface and percieved quality. I added the cost (with options) to see how they stack up. As far as...
I started looking at Haitian molding machines because of their low cost. They are built in China but they do have service and parts available in the US. They have a Mars series of machines that use a servo motor to drive the pump. The press is identical to a normal hydraulic toggle machine...
Yeah, I was referring to a coolant heater you could plug in to warm the engine a few hours before you need to start the car in the morning. An oil heater would be more for reducing engine wear at startup when it is very cold out.
I downloaded the calibration data from a ROM on a 1987 Dodge...
I heard that heated intake air works well on Saturns. I tried it on my 1.9L DOHC Saturn and saw a consistent 3mpg improvement on my short drive to work. I recorded the same 3mpg improvement on 3 tanks of gas until the weather started getting cold. Then my mileage went to hell. I believe the...
Ok, now I see your point. I would like to add to your first point. You said,
1) You will need wider throttle to get the same power, say 7% more airflow, so 7% of the 10% saving is already lost.
The wider throttle opening does result in less pumping losses. This will add a little bit to the...
I agree that you want your peak cyl pressure between 10 and 20 deg ATDC for the best mechanical advantage on the connecting rod. If the stock setup at 14.7 AFR gets you peak cyl pressure at 15 deg ATDC, then slowing down the burn rate with a leaner AFR will give you peak cyl pressure at 25 deg...
If the flame front is slower from a lean mixture than the spark should happen sooner in the cycle to allow the mixture to burn more completely. So I would assume advancing the ignition timing would get you higher peak combustion pressures and consequently more power which would give you even...
As far as slow combustion goes, could I advance the timing a little to compensate for the slower combustion speed of the leaner mixture to help keep the engine efficiency optimum? Any ideas on how to do that on the fly, not just base timing adjustments? Or would base timing adjustment be good...
Hemi: No, I can't distinguish between hotter air and less pumping losses verses ECU adjustments due to hotter air. My guess is they are both pretty small (especially the reduction in pumping losses) but together they add up to a significant savings in fuel. The main reason for this, though...
Good to hear that this might work. I do have a wideband oxygen sensor controller that uses software that allows me to shift the voltage input to the ECU by a certain amount. That way the ECU still "sees" 14.7 air fuel ratio but it is actually getting 15 or 16 air fuel ratio (depends on how...
I was planning on doing that anyways. But I would like to use my wideband O2 sensor to simulate the Narrow Band sensor ouput so I can run the engine a little leaner than stoich. The problem is that I don't know how that will effect things if I add E85 to the gas tank. Maybe I could use the...
Anyone know for sure on this question? I want to use a wideband oxygen sensor on this fan but don't know enough about how the engine detects alcohol content.
