METHOD OF PROCESS TOOLING PREPARATION FOR FILLING OF RADIO-ELECTRONIC PRODUCTS WITH COMPOUND Russian patent published in 2025 - IPC B29C33/72 B05D3/10 C11D7/10 

FIELD: performing operations.

SUBSTANCE: invention relates to cleaning surfaces of component parts of process equipment from dirt. Disclosed is method of process tooling preparation for filling compound with electric radio articles, which includes five steps, wherein component parts of process equipment at first stage are mechanically cleaned from compounds overlaps, at second stage is degreased, at third stage is washed with warm running water at temperature 40-60 °C for not less than 10 minutes, at fourth step is dried, at fifth step is treated with anti-adhesion lubricant, where degreasing at second step is carried out using aqueous detergent solution of calcined soda, wherein metal bath is filled with calcined soda in amount of 8-10 parts by weight, then adding water in amount of 100 parts by weight, obtained solution is stirred until complete dissolution of calcined soda, then the component parts of the tooling are loaded into the metal mesh and immersed into the bath with the detergent solution so that the height of the detergent solution in the bath above the surface of the component parts of the process tooling is 80-100 mm, after that, the bath is closed with a lid and the detergent solution is heated to temperature of 120-140 °C, then component parts of process equipment are held in bath with heated detergent solution at specified temperature for 24-72 hours, then cooled to temperature of 55-75 °C, then metal mesh with component parts of process equipment is removed from container with detergent solution, and at fourth stage component parts of process equipment are dried at temperature 75-95 °C for not less than 30 minutes, then cooled to temperature 15-35 °C.

EFFECT: creation of a method for preparing tooling for pouring a compound with an electric radio article, which is effective when cleaning surfaces of component parts of process tooling from dirt in hard-to-reach places, joints and microcracks, as a result, the tooling surface increases its anti-adhesion properties, as well as the service life of the process tooling increases due to reduction of the aggressive effect during its preparation for the subsequent filling with the compound of the radio-electronic products.
