No. Normal Japanese writing usually does not use spaces between words, so this would normally be written as:
形名を確認します。
Spaces are often added in beginner materials to make the parts of the sentence easier to see.
Not especially. It sounds technical or industry-specific.
In many contexts, Japanese more commonly uses terms like 型名 or 型番 for a product’s model name/number, depending on the exact situation. So if you saw 形名, it would be normal to think of it as specialized vocabulary rather than basic daily Japanese.
