Hello
I need to refine my quotes in my company but I lack strings to my bow! I want to evaluate the cost in raw materials in a relevant way and I need your help/returns.
How do you evaluate the costs of raw materials? Do you have a website/form to evaluate the costs in terms of materials? Typically a 500x500 POM plate thickness 40, how much does it cost? Experience? How do you then evaluate the cost of manufacturing (machining, sheet metal work, etc.)
Thank you
Hello
It all depends on your purchase price and the margins you apply and the drop rate as well as the hourly rate of the cutting operation (plasma/waterjet).

Manufacturing is subcontracted to us, I would like to estimate more accurately, in the pre-project and sales phase, a cost for the raw materials.
Hello
You will encounter several difficulties because you have (do you sell recurring sets but with different configurations or do you only do special and always new things.
1°) the cost of the raw material
2°) the cost of the roughed or finished material if laser cutting
3°) the cost of the material transformed (e.g. a part cut by laser, bent and then taken back to the machine to remove material for example milling or countersinking, and finally welded either automatically or by a welder, etc...
4°) you have the processing cost of your subcontractor and the margin of the latter and the transport cost. A French subcontractor is on average 4 to 4.5 more expensive than a workshop in Romania.
In short, it's very complicated
The solution would be to define with your subcontractors standard parts and assemblies and to define with them a set of Gross, semi-finished, finished prices since it is a question of having a first estimate before the project. On the other hand, for sales projects, you need to work more in partnership with your subcontractors in a win-win relationship from the alpha versions of your package.
Cf: a very recent post on costs that will tell you more.
Kind regards

After some research, PMO is a semi-crystalline thermoplastic material so for me I will make quotes from people installing this type of products.
Thank you all for your answers, all very constructive.
I did not expect an easy and single answer. We are an industrial integrator/mechanical design unit. We do not work with raw materials. It's only a special machine and not a series, at least for the moment. For my part, in order to have a better estimate of the prices, I will build a database of the different pieces I have been able to make so far and indicate the price paid for the realization. This will allow me, I hope, to better evaluate the cost of manufacturing my solutions.
@Zozo_mp: What position are you talking about?
