The cut edge of a finished product of the normal sealing cube is usually rough and deformed with obvious cracks, and of the thicker parts, this condition becomes more apparent. This is because when the normal seal dies operation, they push the fists to bend and cut the material, and then remove the final cut part or waste material from the sheet. If there is a need for precise assembly at the cut edge, a secondary editing job will then be unavoidable to fix the cut edge. Otherwise, if there is no need for precise assembly or cosmetic purpose on the cut edge, regular sealing cubes will be a utility choice for mass production.
How to reduce production costs? Instead of using poor quality materials, look for advanced production techniques!
For example, the image below is a counterweight to a measuring device. Since the counterweight part is not for cosmetic purposes and its cut edge is not for assembly, it is advisable to use regular sealing dies in mass production.
The counterweight consists of SPHC materials with a thickness of 10mm. Made with regular sealing dies, the edge edge of the part is rough with twisting and deformation.
The slim firing press provides the parts with smooth and vertical cutting edge with precise dimension tolerance. Compared to the regular sealing dies, the design of the dies of the fine blanking type has many differences. Take the vacuum dies for fine type vacuum as an example. There will be v-shaped convex rings drawn around the top plate sealing near the edge of the cutting edge. While empty, the upper and lower plates will tighten the parts. After that, the blank punches will fall to cut the sheet materials. In the meantime, there will be ejecting the same size of perforations by quenching by pressing down to resist the sheet material upwards, ensuring that the cut edge of the sheet material will not bend and deform after cutting. In general, the width of the cracks between the thin-walled perforations and the upper / lower plates will be approximately 0.5% of the thickness of the sheet material. This is almost 1/10 so much the width of the traditional seal cracks dies, so as to prevent the cut edge from tearing.
The pole piece consists of SPHC materials with a thickness of 6mm. Made with a fine type of misery, the edge edge of the part is smooth and vertical, which is not second in quality made by grinding or laser cutting.
With the numerous features above, the thin die type is quite suitable for making two-dimensional parts. Also, when it comes to mass production, fine type averisia has an advantage in its low cost compared to cnc milling and laser cutting. As mentioned above, if we use CNC milling for 2-dimensional parts with precise assembly and cosmetic reasons, the parts will have high accuracy but with high manufacturing cost and low efficiency. If we use laser cutting, although the manufacturing cost is low and the efficiency is high, the dimensional accuracy is lower, only tolerances +/- 0.2mm. Besides, it is easy to have burnt marks, sharp edges, and burrs on the cutting edge when using laser cutting, so we will need secondary treatment to achieve enough precision and cosmetic requirements, and manufacturing costs and procedures will increase further. If you are planning to cut down on construction costs, increase construction efficiency, and have the need for expensive assembly and cosmetic appearance, get the slim formula out there for your plans.
