Accumulator boxes

it is known that the boxes for accumulators are made from (ELa s, hardable Plastics like Bartgammi or bitumen mesen or also, thermoplastic masses are produced »hit consideration the low strength values of the masses used must Wall thicknesses are chosen to be so strong that the weight of such Box a relatively large proportion of the total weight β β the battery turns off. These branches are very sensitive to blows, and mechanical damage easily causes cracks to form on * which lead to the box becoming sealed. In the preparation of Such a box from molding compounds often form cavities that are not recognizable by eye inspection and usually only appear after commissioning «

The hiring of the box described below is thereby characterized in that the actual box or the casing is lined with a thermoplastic cash register * FQr the sheathing can vary depending on the intended use and the mechanical properties put in the box by way of Drawing process or welding process those made of steel, non-ferrous metal or light metal are produced «Es las * , plastics based on cellulose «ceramics are also suitable or those made of cardboard, kunat wood, pressed wood, etc. use "the otherwise because of the lack of chemical and electrical properties could not be applied or lack of fluid s51 elite

Eaeser box made of the aforementioned substances is lined with an electrically and chemically inactive thermoplastic Hasse. This lining can be done in the injection molding process in such a way that the casing is introduced as the core in the injection mold and the lining is made in the well-known injection molding process. The thermoplastic The compound forms a homogeneous connection with the Tfesa coating *

The lining can be made in the well-known fluff öprit? Sv »rfahrön are »whereby the thermoplastic Hasse is liquefied by heat is applied using the gppitK method
