drawing mold design. how long?

[Nikolaus]

Hello, I'm 24 years old and I've been working recently in a company's technical office specialized in plastic molds and sheet metal molds.
In the office we are two: I (designer) and a colleague (designer and programmer cnc).
for every new order, my colleague develops the project in 3d and I take care of the table and drawings.
But the manager lets me understand that I spend too much time, given the short times we have.
my hand is: how do I optimize my times? once he made me (the manager) a joke saying that on average it is calculated 1 hour per single drawing. Of course every mold has its history and its characteristics and you can not establish a standard timing, but according to you, 80 hours to develop a progressive mold with a total of 70 details (to be drawn) is really so much? considering that I also have to develop the ball (inferior overall design, superior and possibly intermediate).
Do you follow a table to adjust? Thank you.

I don't know exactly how complex your drawings are, but I tell you it depends on the technique:
- if there are already cleverly divided assemblies and subassiems, just make a table with the views and one with the explosive and it takes on average not more than 15/20 minutes
- if who designs the solid model puts tolerances, indications, compile the properties you put little to make the table with automatic quotation
- if instead you have to undergo the genius that sets to great lines something that you do not even know that reasoning is behind, tolerances, treatments, etc. I would say that it is very expensive
- you need to combine cad tools, human brain, know how to use both to optimize things.

realize that on average for a flange with 3 or 4 odds it takes 2 to 5 minutes to make the table, fill out extra data, roughness and save. averagely for complex carpentry of machine tool we go from 3 to 4 hours to run.
medium cut and perforated plates I would say 5 to 10 minutes.
averagely in 10 hours I have always put on the table more than 25 details. 30.
if you take a look at geometric tolerances and more we say that you can get 18 details in 10 hours.
separate with exported data table.
Preset sheet templates with views depending on the type of piece to make, use the pack an go immediately including the table excels everything for high productivity.

Unfortunately the designer (I believe for reasons of time) does not set any features to the models that I pass. In fact, my greatest loss of time is to find in the assembly the functionality and use of any hole or superficial. to understand, a few days ago I had to draw a 600x600 matrice plate, with hollows (calibrate and not) and something like 200 holes (haleseed, threaded, unloading, lamature, etc...). obvious that for any geometry I had to recheck its functionality (as well you know the mechanics does not forgive distractions) and this for me is a waste of huge time.
Anyway thank you for the answer, you were exhausting!

If I can, I design thermoplastic molds for over a decade and your problem is very felt .
Let's say that part of the problem is to be attributed to your inexperience in the field, in a while you will be able to understand at the glance what are the components that need to be pushed tolerances and which instead are scarce.
but that is not enough, as mechanicalmg said to optimize the time needs teamwork and organization.
for example the use of bookcases for the vice or standard parts that can automatically create my pockets .
pockets that color the seat with different colors according to their tolerance.
already only this small trick allows to pass to those who make the tables a geometry in part more understandable.
there are companies that have optimized the cam process for coloring, the camcorder performs a type of processing just by choosing the areas to work for color.
with this system the boards were almost completely abolished.
I, for example, have a request for 2d boards on my molds in order of 10/15 % of orders .
It usually only takes only one set with ball, which is automatically tied to a distinct base that takes the values and characteristics of the components from the attributes of the single piece present together.
Of course not all cads have these specifications, it is up to you to study the tool that comes to you and exploit it to the best

thanks ipdesign, you were very clear!
