Where do you make super-precision metal capillaries?

Capillary tube refers to the tube inserted into the liquid, will produce a liquid level suction phenomenon (the liquid level inside the tube is higher than the liquid level outside the tube). Metal capillary refers to the capillary made of metal material, usually refers to the inner diameter of φ1 metal tube. The general metal capillary is basically made by cold drawing and drawing. The manufacturing accuracy depends on the equipment and technology of manufacturing. Specifically, it is related to the factors such as "outer mold, inner core, drawing equipment, technology and people".

1, the outer mold

The material of the outer mold is usually divided into alloy and polycrystal, the highest accuracy can reach about ±2 microns;

2, the soft-core

The MATERIAL OF INNER CORE IS MULTIFARIOUS, WITH T9A AND HSK-9 MATERIAL IS THE MOST, THE FORMER IS DOMESTIC, USE MORE GENERAL. The latter is imported from Japan, the price is very high, but the precision is also higher, the highest accuracy can do ±2 microns;

3, stretching equipment, divided into disk pulling and self-pulling, disk pulling efficiency is high, but the accuracy is low. The self-pulling accuracy is relatively high, but to achieve ultra-high accuracy, the self-pulling equipment must be modified, such as the speed of stretching, uniformity, vibration, etc.

4,

Because there are many kinds of metal materials, different characteristics. Although EACH manufacturer has a set of tensile calculation formula, but to manufacture a high progress of metal capillary, the key is to supplement the formula of modification, which comes from the accumulation of years of experience, is also the core technology of tube manufacturers.

5,

Needless to say, the human factor, trained pipe technicians are the guarantee of the preparation of high precision metal capillary.

In summary, the highest accuracy of metal capillary fabrication is within ±5 microns, and some specifications can achieve a range of 5 microns.

Ningbo Olek Electronic Technology Co., Ltd. is recommended here. The company's history of tube making can be traced back to the 1980s. It is one of the earliest tube making enterprises that introduced technology and equipment from Japan. In the 1990s, it was the only enterprise that could produce CRT TV cathode bushing in China. Now mainly committed to high precision special capillary manufacturing, such as rare metal capillary manufacturing, such as titanium capillary, niobium capillary, tantalum capillary and so on; In addition, special specifications of conventional metal capillaries are also produced, such as capillary tubes with very high precision, capillary tubes with very small pore size, ultra-thick wall capillary tubes and ultra-thin wall capillary tubes.
