| 1)
What best describes what you wish to dispense? A liquid? A gel?
Paste? Suspension? |
| |
| 2)
What is the viscosity in either engineering units or practical terms
suck as "like water", SAE 30 oil, Karo Syrup, Grease,
etc.? |
| |
| 3)
Does heat influence the viscosity? Will warming the material significantly
increas its flowing tendency? |
| |
| 4)
Is the material stable? Does it change in viscosity over its expected
working life? Does the material contain a pigment or other suspended
solids which might settle out if not agitated in a holding vessel?
Will the material "skin over" due to loss of solvent? |
| |
| 5)
Do you wish to apply more than one shot at a time? If yes, how many?...10,
30, 100 or more? If you do, what is the pattern of the shots...all
within a square or rectabgle? Of what dimensions? |
| |
| 6)
What reproducibility do you requuire? Shot to shot stated in + or
- % of volume dispensed. |
| |
| 7)
Is the material you wish to dispense tacky or stringy? |
| |
| 8)
What
volume (size of shot) do you wish to dispense? Give it in engineering
terms (ml, fluid ounces, etc.) or in practical ter,s such as "a
tiny drop" or "a teaspoon". |
| |
| 9)
How
frequently do you wish to dispense in terms of cycles per second
or per minute? |
| |
10)
How will the part being handled be presented to the dispense station?
By hand? By robot? And what will be the orientation of the part?
Do you wish to dispense upon both sides of the substrate? We can
do that to! |
| |
| 11)
How
will the treated part be delivered after the dispense? removed by
hand? Integrated into a linear or rotary indexing process? |
| |
12)
Does the material to be dispensed require heating to be properly
delivered? What temperature range is required? Is there a compatibility
problem with some materials?
