Brown mold spring:

Brown mold spring compression deformation in 16%, 18%, 20% range, mold spring is a heavy load compression spring, made of rectangular section steel wire, rectangular section mold spring and circular section spring compared with the same space, the use of rectangular section spring cross-sectional area is large, so its stiffness is large, can be used as a heavy spring. The stiffness of the die spring with a rectangular section is also close to a straight line, so the stiffness is relatively stable.

Network optimization materials:

Barometer according to its measured material is not the same, waveform mold spring in the case of the instrument panel name under a table 1 often required tone horizontal line, and marked with the name of the unique substance, co2 table must also be marked with bright red "no oil" words.

The components of the barometer should be firmly installed, and there should be no rust, cracks, holes and other defects that affect the measurement and verification characteristics.

To measure the vapor body of the barometer in the watch case watchband on the reverse side of the safety hole, safety hole must have antifouling equipment. When the isolator cracks, the butterfly mold spring should be able to enable the vapor body to escape from the watch case strap reverse (except for the instrument panel that prohibits the measured substance from escaping outside the table).

Barometer case measuring range data and marking should be detailed and clear. Case measuring range ruler should be evenly distributed, the center Angle of the package is generally 270°, marked with data measuring range line total width can not exceed the requirements.

The barometer needle should be inserted into the whole measuring range line, the total width of the needle marking end should not exceed 1/5 of the minimum measuring range spacing. The spacing between the hand and the dividing dial plan should be in 1~3 mm category watch case strap diameter above 200mm (including 200mm), its hand and dividing dial plan spacing should be in 2~4mm category.
