Don't imagine that all you'll need is a moulding press and some moulding powder and you'll by ready for the competition. The plastic moulding business is probably already overcrowded by peace-time standards and it's not the main way in which plastics will develop anyway. You're probably in the plastics business already and don't know it. Don't you already have to bind things together? Don't you make something that could be stronger, lighter or more weatherproof? Are you in paint, timber, textiles, paper, or a hundred and one other trades?
