For over 35 years, ever since the first edition of this explanatory collection of tried and proven examples of molds, the "Gastrow" has been serving two generations of mold designers and builders as reference work and as a problem solver for design tasks. That is how the new "Gastrow" should be regarded: as a book by the practical and for the practical, containing solutions for problems and design details for configuring injection molds.

For this fourth edition, changes and supplements were once again undertaken with the aim of representing the state of the art. At the same time, our aim was to preserve the knowledge that is "Gastrow’s" lasting heritage. One new feature is a table of contents of all the molded parts produced in the molds described here. Again it was difficult, and not achieved to the degree desired, to obtain new examples of innovative mold building from actual practice for this new edition. The world has changed since "Gastrow". That may be regrettable, but it is certainly one of the results of "globalization": more or less justified worries about piracy of brands and products, as well as the worldwide trade in obvious plagiarisms advise us to be cautious. Although almost every mold is one of a kind, many people are shy about revealing their design ideas: copycats pay no development costs.
Nonetheless, the competition for and the education to excellence presuppose the presentation of capabilities. In one way or another, anything that can be purchased can ultimately be duplicated. The know-how embodied in every product often cannot be reconstructed without limitations, or at least not before many attempts to do so have failed. Creative entrepreneurs (mold builders) can obtain a competitive edge in this way. We owe thanks to those who have given their kind assistance in this task along the way.
