Text alignment and form of connectors (edges) in tikz tree

I'm completely new to tikz and try to draw a tree structure.

I have tried different options, but could not modify it as I wanted it to look like.
It currently looks like that:

Tikz code

\documentclass{article}

\usepackage{tikz}
\usepackage{tikz-qtree}
\usetikzlibrary{trees} % this is to allow the fork right path

\usepackage[utf8]{inputenc}

\begin{document}

\begin{tikzpicture}[grow'=right,sibling distance=0.1cm]
\tikzstyle{level 1} = [level distance=3cm, text width = 2cm]
\tikzstyle{level 2} = [level distance=3cm, text width = 2cm]
\tikzstyle{level 3} = [level distance=3cm, text width = 2cm]
\Tree
[
[.{Pressen}
[.{uniaxiales Pressen} ]
[.{isostatisches Pressen} ]
[.{Vibrationspressen} ]
[.{Stampfen} ]
]
[.{Plastisches Formen}
[.{Extrudieren} ]
[.{Drehen} ]
]
[.Gießen
[.{Schlickergießen} ]
[.{Druckgießen} ]
[.{Spritzgießen} ]
[.{Foliengießen} ]
]
]
\end{tikzpicture}
\end{document}


The resulting pdf output:

(red line drawn by hand, see below)

I'd like to achieve the following

• linebreak in node "Plastisches Formen"
• edges not straight but horizontal/vertical - like sketched in red for one edge
• text of each level aligned left
• is it possible to adjust the level distances automatically to the width of the largest node in the level, so that I do not have to set "level distance" by hand?

If forest is an option:

\documentclass[tikz,border=3mm]{standalone}

\usepackage{forest}
\usepackage[utf8]{inputenc}

\begin{document}

\begin{forest}
for tree={grow'=0,
anchor=west, child anchor=west, fit=band, parent anchor=east, edge path={\noexpand\path[\forestoption{edge}](!u.parent anchor)|-(.child anchor)\forestoption{edge label};}, l sep=1cm,}
[, calign=child,  calign child=2
[Pressen
[uniaxiales Pressen]
[isostatisches Pressen]
[Vibrationspressen]
[Stampfen]
]
[Plastisches\\Formen, align=center
[Extrudieren]
[Drehen]
]
[Gießen
[Schlickergießen ]
[Druckgießen ]
[Spritzgießen ]
[Foliengießen ]
]
]
\end{forest}
\end{document}


2nd version:

I'm not sure to understand what all nodes "raggedright" means, but may be option align=right does it.

The other comment about aligning all same level nodes can be done with tier/.pgfmath=level() option.

\documentclass[tikz,border=3mm]{standalone}

\usepackage{forest}
\usepackage[utf8]{inputenc}

\begin{document}

\begin{forest}
for tree={grow'=0, l=0, l sep=2em,
child anchor=west, anchor=west,
parent anchor=east,
tier/.pgfmath=level(),
align=right,
edge path={\noexpand\path[\forestoption{edge}](!u.parent anchor)|-(.child anchor)\forestoption{edge label};},
}
[, calign=child,  calign child=2
[Pressen
[uniaxiales\\ Pressen]
[isostatisches Pressen]
[Vibrationspressen]
[Stampfen]
]
[Plastisches\\Formen
[Extrudieren]
[Drehen]
]
[Gießen
[Schlickergießen ]
[Druckgießen ]
[Spritzgießen ]
[Foliengießen ]
]
]
\end{forest}
\end{document}


• thanks a lot - that looks quite nice already. However, how can I get the text of all nodes "raggedright" and all texts of level 2 aligned left on the same vertical line? – MostlyHarmless Mar 12 '15 at 12:42
• @Martin. Please, look at updated answer. If you also want first level nodes aligned to the right like second level ones do to the left, I don't know how to do it. My expertise in forest is not enough. But you can always make a new question. I'm sure our forest experts will help you. – Ignasi Mar 13 '15 at 9:20
• thanks a lot. No, with "raggedright" I meant left justified (like here sharelatex.com/learn/Text_alignment#Left-justified_text ) so align = left should be the needed option. (In your first example the text in each node was centered) – MostlyHarmless Mar 13 '15 at 9:24
