Professional Custom Lamp Holder Accessories Manufacturer

Material: ordinary incandescent lamp holders material 08F lamp strip. Is divided into the P, S, Z, three levels. General suppliers can do the S-Class (D-leveling). The mechanical properties of the brass band as follows (see Table 1).

Visible 08F strip the mechanical properties of H62 copper strip close to or little difference. Elongation slightly worse than H68 and proximity H62. And as a drawing stamping performance is strongly influenced yield ratio (yield / drawing strength), 08F strip was 0.56, in line with the E27 product manufacturing requirements.

Accordingly, the performance from the material point of view, the production of good quality 08F strip E27 lamp holder is feasible.

Technology and equipment: steel strip and copper strip material mechanical properties are similar. The original copper E27 lamp technology can adapt used in the steel material; the lubricating surface rust spindle oil plus the use of materials factory original copper material saponification emulsion no problem.

08F strip hardness (including shear strength and tensile strength) is slightly higher than H62 brass band equipment, but the original stamping equipment working pressure coefficient, so no problem on the tonnage. Roller rigid because of the special equipment, thread rolling equipment, mold material and rolling process better, to adapt.

The pressure glass forming: coefficient of linear expansion due to the thermal conductivity of the steel strip is slower than copper, and low coefficient of linear expansion of the steel strip (118 * 10-7K-1) than that of copper (165 * 10-7K-1), closer to the glass therefore more advantageous to match the glass and the lamp housing and elimination of stress. In addition to the lamp housing softening better than copper, to increase the mechanical strength of the lamp holders.
