This question is at the heart of good Swedish syntax, and it deserves an elaborate answer. Putting it briefly, we say and write Det tas kontakter med stora industrier because it sounds better. Impersonal constructions like this are very common in Swedish.
It is perfectly correct to say Kontakter tas med stora industrier, but it sounds stilted. Similarly, for "A bird is sitting in the tree", we say Det sitter en fågel i trädet. One would not expect to hear the correct but unusual sentence En fågel sitter i trädet.
It is a dummy subject, not dummy pronoun. There is no such thing as dummy pronoun.I think "det" here is a "dummy pronoun", similar to "it" in English. See: Dummy pronoun - Wikipedia
[...] but there is the additional "Det", so the question would be, why do we need the "det" here? And what function does it play in the sentence?
Just to add to AutumnOwl's correct observation that we are dealing with a dummy pronoun here, the function of the additional det is that of the syntactic subject. In Swedish, all sentences (with the exception of imperatives) need to have a pronounced subject and that position is usually filled by the noun that expresses who/what is performing the act described by the verb. If that noun is missing for whatever reason, we need something else to fill the subject position of the sentence. This can be done by moving the object of the verb (and possibly the indirect object) to the subject position, but it can also be filled with a dummy subject det. Typical types of constructions where this is an option are:I think "det" here is a "dummy pronoun", similar to "it" in English. See: Dummy pronoun - Wikipedia
Ontological claims about what exists and what doesn't exist will obviously depend on the level of analysis. Pronouns exist so why not dummy pronouns? Although I prefer the term dummy subject in this case because we are dealing with a syntactic requirement in Swedish, the term dummy pronoun (though equally valid for the case at hand) may serve in a more general discussion about non-referential pronouns regardless of their syntactic position.It is a dummy subject, not dummy pronoun. There is no such thing as dummy pronoun.

Dummy subject is the term I'm used to, but the label dummy pronoun is useful if we admit that such a pronoun can also have the role of object, for example in phrases such as She's made it as a singer! or Get it?Can you give an example of a dummy pronoun, not related to the syntactic position?
I did not make any claims about dummy pronouns not being related to a syntactic position. In a sentence, they will naturally occupy some syntactic position, but insisting that they are necessarily dummy subjects misses what Segorian points out in 10#:Can you give an example of a dummy pronoun, not related to the syntactic position?
And to add some examples from Swedish where the bolded pronoun can be classified as a dummy pronoun:Dummy subject is the term I'm used to, but the label dummy pronoun is useful if we admit that such a pronoun can also have the role of object, for example in phrases such as She's made it as a singer! or Get it?
Is there a point you want to make or are you just curious? To find an answer to your question, you can read the first sentence of the Wikipedia entry in the link provided by AutumnOwl in #5. But then, we will have gone full circle as this was precisely what you seemed to take issue with in #7.What makes these promouns "dummy"?
Only, I believe, the fact that they are used as dummy subjects in these particular instances. I can see the logic in resisting the label “dummy pronoun” on the grounds that the words in question have no characteristics or properties that make them “dummy” per se. A dummy pronoun is only dummy insofar as it is used as a dummy subject. (And now I won't be able to use the word dummy for a while.)What makes these promouns "dummy"?
