Pricing Jobs

[Guest]

Most of our 1st jobs were already quoted and industrial type work but now we are getting request for other than industrial. I was wondering how you guys quote parts? Rule of thumb or calculated spread sheet…

Re: Pricing Jobs

DEFINING THE APPLIED COST FORMULA


192.3 x Transfer Efficiency = Coverage per lb. of powder
Specific Gravity x Mil Thickness at the applied mil thickness


What is the Constant 192.3?
The amount of surface one pound of powder will cover one mil thick, at a specific gravity of one, at 100% efficiency.

How do you determine Transfer Efficiency?
Only by measuring a representative production can the actual powder usage be determined accurately. For approximate usage, the following ranges can be used:


Cyclone style reclaim booths: generally yield 85-95% efficiency.
Cartridge style reclaim booths: generally yield 90-97% efficiency.
Spray to waste (non-reclaim) booths: First pass transfer efficiency has many variables.
The variable the most effects transfer efficiency is part shape and size. Below are some recommended efficiency ranges:


Part Shape Approx. Transfer Efficiency
Wire goods/tubing 20-40%
Sm.-med. Enclosures 35-55%
Lg. Enclosures/flat ware 50-70%

What is Specific Gravity?
Specific gravity is the ratio of the weight of a given volume of liquid or solid to the weight of an equal volume of water. Powder manufactures normally calculate the specific gravity for each powder formulation and provide the number on the product date sheet.

Mil Thickness?
One mil equals one- thousandth (0.001 or 1/1000) of an inch. Actual film thickness can be calculated by weighing the part prior and after coating, or taking several mil readings using a film thickness gauge and averaging the readings. Powder manufactures normally provide a recommended film thickness range on the product date sheet.

Example: Gray with a Specific Gravity of 1.68 applied at an average of 2.3 mils in a reclaim powder system.

192.3 x 95% TE = 182.69 = 47.3 square feet of coverage per pound
1.68 SG x 2.3 Mil 3.86

Re: Pricing Jobs

That looks like a big formula king...lol. I guess I cheat and just call other places around me and see what they are doing the parts for and cut the price by 10%. Works for me, but I am not smart enough for what you were talking

Don't feel bad, many of us do the same thing. I call usually go with the lower price, an average of 3-4 places, or whatever I think is closest to a fair value.

Re: Pricing Jobs

You’ve seen the parts we’re coating now and we have weighed the powder box before and after so yes we can currently figure cost for each family of parts. Yes, I had started a spread sheet when you originally sent this to me a few weeks back. I was just looking for some other ideas that aren’t quite so calculated. I see now you’re not going let me use rule of thumb…..but then again, you are the King…

Re: Pricing Jobs

I'm sorry I thought math was only a problem for me If you tell me the size of the part, prep and the powder they want, I will be your slave this one time

Re: Pricing Jobs

I have quote software

Where can I acquire some of this quote software?

Re: Pricing Jobs

Hell yeah Harleydad, where do you get this magical software?

Re: Pricing Jobs

I have a software CD, but again you get into the same calculation thing. It does take a good deal of time to tweak it to work for custom coating like we do. It's designed more for automated production work. I tried it a few times, and went back to winging it! That and asking Harleydad to help me price it!

Re: Pricing Jobs

Pricing the custom stuff with all of the stripping and out gassing problems is like spittin into the wind.......if you can duck before it hits ya back in the face ya done good

Re: Pricing Jobs

Quote a price to your customer and then tell them if you find a cheaper price you will match it,
But they must produce you a copy of the cheaper quote.
You must first find out what your total applied costs are including profit before you quote the part.

And that, my friends...is the hard part!

I read this on one of the forums...... If you give a quote and the person looks like he just swallowed a dead fish you are just about right...............

Now thats messed up... probably true but messed up.
