Spanish to English Marketing Advertising / Public Relations

This is in a website for a Spanish company that does point of sale advertising (like cardboard display stands and table top stands for products) and packaging. According to the Oxford Spanish to English dictionary, un troquel is a "die", but I don't see how that fits with this context:

XXX ofrece la posibilidad mediante un estudio previo sin coste, de reducir costes a partir de unificar troqueles, materiales, manipulados o mejorar las características de los packs

And later, when listing what they provide the customer:

Planos de troqueles con pruebas.
