“Tungsten is a metal with a melting point of 3410 + / 20 ° C. It has the highest tensile strength at temperatures above 1650 ° C. Impure metal tungsten is very brittle and difficult to process. But pure tungsten can be sawed, spun, Pull, forge, squeeze."
Smit Röntgen, the manufacturer of basic medical imaging components, applies pure tungsten 3D printing to the medical field. Smit Röntgen is able to melt pure tungsten at a high temperature of 3422 ° C and cure pure tungsten by powder bed selective laser melting to create free-form surfaces. Components.
In the past 10 years, Smit Röntgen has gradually invested in 3D printing technology and has gradually replaced traditional technology to provide customized and innovative parts for the medical industry, and became the first company in the world to use pure tungsten for 3D printing.
Of course, having a 3D printing device is only the beginning, and more importantly, process knowledge. The complete process chain is especially important in pure tungsten printing, from design models to processing parameter settings, product 3D printing, and post-processing, quality inspection. Smit Röntgen's current 3D printed tungsten products are available in sizes 230x230x200mm.
Pinhole collimator
3D printing is very effective for creating thin-walled parts, giving manufacturers a great degree of freedom in the production of collimating aperture angles and shapes. Smit Röntgen's pure tungsten printing technology can be used to make pinhole collimators and can be better due to tungsten materials. Used in X-ray scanning equipment environments. Beamforming solutions can also be provided through 3D printing, which extends the use of tungsten products to a wider range.
X-ray filtration
Pure tungsten is an excellent X-ray absorbing material and is environmentally friendly. Through 3D printing technology, tungsten products can be produced in large quantities like X-ray scanning equipment as freely designed. These tungsten parts are rich in variations and low in cost.
Through post-processing, these tungsten parts can be used in vacuum compatible environments, including X-ray tubes. At the same time, the high melting point of tungsten makes these parts can be used in extreme high temperature environments. In addition, the low expansion rate of low temperature makes tungsten the most stable choice in an environment with large temperature variation, so that its application range is not limited to Medical industry.

Self drilling Screw made of 410 stainless steel, high hardness (40 Rockwell C), steel process.
Drilling screw is also very strong hardness, compared to the ordinary screw up, not only to maintain the ability is good, the connection object effect is also very strong, for the performance of the screw, are generally does not need auxiliary processing, can be directly on the object directly drill a Kong Sue into objects, not just use rise very convenient, Also can greatly improve the efficiency of work. This kind of drilling screw can be said to be the first choice of workers in various fields.
So what is the use of drilling screws?
1 stainless steel plate, metal plate, galvanized steel plate, engineering installation.
2 metal curtain wall metal light compartment and other indoor and outdoor installation.
General Angle steel, channel steel, iron plate and other metal materials combined installation.
4, automobile, container, shipbuilding, refrigeration equipment and other assembly projects.
