Latest Patents
Dreinhoff's latest patents focus on methods for fashioning ink channels in write heads for dot-matrix ink printers. The first patent describes a method where form needles, surrounded by piezoelectric drive elements, are aligned in a casting mold according to the desired course of the ink channels. This method allows for the casting of a compound that forms the ink channels, ensuring insulation of the drive elements from the writing fluid. The channels are filled with a liquid or dissolved plastic, which creates a thin protective layer on the inside channel walls. This innovative approach enhances the production engineering of ink printer heads that operate on the principle of individual drop ejection.
The second patent elaborates on a similar method, emphasizing the use of form needles coated with a parting agent. An envelope coat is applied to these needles before they are placed in the casting mold. This technique ensures that the inside channel wall is formed effectively after the removal of the form needles and parting agent. Both patents serve the purpose of improving the manufacturing process of ink printer heads, making them more efficient and reliable.
