The first part of this section deals with implementing an idea right up to the production of a prototype – it creates a new glass product. Regardless of whether it is a glass lens, glass ball or ……..
The idea is the beginning for a new glass product
To start with, there is an idea of us working together with our customers right up to the finished product. The first step is a drawing with all the necessary details like, for example, precise measurements, tolerance specifications, description, etc.. We should also be informed of the intended use or purpose, such as the exact requirements set by the customer for the pressed glass product. These requirements also decide on the type of raw glass needing to be used. There is usually the choice of either soda lime glass or borosilicate glass.
Drawings as a basis for development
As soon as we have the drawing, details will be clarified with the customer and, if necessary, any appropriate changes will be made. Primarily, it’s about the feasibility and the type, like the mould, must be built for technical reasons in order to achieve the best possible result in glass pressing. If changes are indeed necessary, it is usually sensible to prepare a new drawing. This is then the basis for tool manufacturing. In tool manufacturing a 3D data file is created, in other words a graphic (plastic) drawing illustrating the complete structure of the tool. The tool is manufactured only when this drawing meets our expectations and requirements and the customers‘ wishes are therefore adhered to.
The tool is tested and optimised
The next phase is fairly crucial. The finished tool is then prepared for production. First of all, the tool is checked, measured and tested to see whether the specified criteria have been met. If the tool is found to be working, a further step is important in order to ensure good results at compression. The tool must be attached to the press in order to clarify and test whether the optimal result can be achieved at compression. Once this point has been established, the mould must be redeveloped. Now the necessary holes are drilled into the mould, so that the resulting air can escape optimally at compression. This is also important with respect to the issue of reworking.
In part one of our blog, we have described the individual steps right up to the first prototype in order to manufacture, for example, a glass lens or glass handle for bathroom fittings. To be continued next month in our blog…
