cost estimate for a mould for funnel and hairstyle

[kle31]

Good evening everyone is kleids and I am a mechanical engineering student. I have to prepare an estimate of the costs for a process of double funnel and hairstyle. I better explain, we have to design a cup in aisi 304, 8 cm in diameter and 10 in height, starting from a sheet of 1mm thick. we have to make a hairstyle of a disk of diameter 200 cm, then a first funnel that reduces the diameter to 150 cm and height 2,6 cm, a second funnel diameter 8 cm and height 10. my group wanted to start from a sheet 50 cm x 50 cm and design a mold that cut 5 discs from 20 cm in diameter and then the molds for the next 2 funnels, even here they would like to make all 5 together, but I doubt if you can do it.
I would be very grateful if you could tell me the formulas to estimate the costs of the molds. if it is not possible to do as they say, even a mold that draws a disk at a time and 2 molds that put a disk at a time is fine. for hairstyle the required tonnage and 60 ton while for the funnels we are on 15/16 ton. obviously if you can make all 5 hairstyles together we will multiply the tonnage for 5. if it is not possible we will start from a coil and we will make one at a time the steps. Thank you very much for your help and patience.

everything is possible, just know the tonnage of the press of the "client".
power systems can be made by means of a system that transforms the coil into frames by means of a steering basket or by means of a destaker that browses the various frames on a conveyor belt.
another method is to have the coil that unrolls and is then smoothed to finish in press and be worked step by step. will be the press to cut the sheet for scraps.
These modes depend on what and how you want to equip the "client" according to the flexibility of plant.

As for the costs of a mold, first thing makes me curious to know what they teach you at university.
going to the practical side, you have to design the mold, know costs them purchase material and mechanical processing, cost assembly, cost engineering, costs accessories and general.
Moreover, those who make molds use similar costs of molds what a student cannot do.

I would say that it is a nice complex work that for a university student it becomes complicated not having suppliers to whom to ask....but in fact you can the same call and contact the various suppliers, better if Italian and available, and get to make a budget offer of the components, explaining to them that it is for a university job.

if there can be useful, I can tell you that an Italian company that makes aluminum pots has purchased three plants so formed:
aspo wrapper with straightener, power supply entering the first press. the press pulls the discs wide by moving the tape transversally.
the discs fall on a conveyor belt and are stacked in specific pallets.
another station picks up single disk and loads it on the conveyor belt and enters the press and making multiple steps is pushed and finished.
as you can see there are different ways of working....very different.

table and use it by saving it by name importing new parts

rightly as he wrote @meccanicamg, there are no simplified formulas with parameters that allow you to calculate the cost of realization. a mould consists of numerous components defined in the design field in function of both materials and forms to be obtained as well as the type of press used; in your case you have only the indication of the piece to be obtained but, in any case, you must start from the design of the complete mold with all its parts evaluating the functionality, after which it will be one by one, to calculate the cost according to the respective processing cycle and the material.questa thesis, da pag. 64 (projecting a mold), can give you directions on the work to be done upstream before switching to the anticipation of the various components to get the complete cost of the mold.

Thank you all. would you tell me those companies that produce pots, how much did they only pay for the molds? Because maybe I can get something out of there. then for the power system we think well. But just to get an idea, I'd like to know how much that mold cost him. Thank you.

 

[meccanicamg]

cost, embroidery and gain.
it can cost a little but then if it serves to have so much gain the supplier does so much embroidery.
many times prices do not cover only costs.
a mold from a few euros, if it allows to become millionaire....it costs 100 times its pure cost.

I don't need a very precise thing, a media would be good, something you have just experienced so you have an idea.

but that strange this thing that to two different students (but both Lombards) is asked to calculate the cost of a mold (the other guy was for a casting mold), almost assuming that there are dedicated formulas. will be the same professor? However, for what I saw, every mold has its own history and it is difficult to calculate its price starting from the dimensions of the building. there are so many variables, not last, the drawing of pieces in the life of the product. as they have already written, if you are a company that has a history of molds purchased, for similarities you can approximate a price, but starting from scratch, I think it is impossible to go near with good approximation (+/- 5%). the only one is to ask for courtesy to a available die and to give a quotation made for similarity; This will make him waste a little time and if you show up, asking smart questions, maybe from this contact could bring birth to a working relationship once you graduate.
