What is the difference between precision metal stamping parts and machining stamping parts? +15 years of experience manufacturer

Precision metal stamping parts are obtained by precision blanking (referred to as fine blanking). It is a sheet metal processing method developed on the basis of ordinary blanking technology. It improves the guiding accuracy, reduces the gap between the convex and concave molds, and increases Technological measures such as reverse pressure and V-ring blank holders have resulted in the realization of fine blanking or fine blanking combined with other forming processes under strong three-way compressive stress conditions to obtain fine blanked parts. Compared with the ordinary blanking process, precision stamping has the following characteristics: 1. The roughness of the shearing surface of ordinary blanking parts is higher than that of the section, while the roughness of the shearing surface of the precision stamping parts is lower than that of the section; 2. Ordinary blanking The dimensional accuracy of parts is generally IT9 to IT12, and the dimensional accuracy of precision stamping parts is generally IT7 to IT9. For sheet metal with a thickness of 0.5MM to 1MM, the internal dimensional accuracy can reach IT6; 3. Precision The structure of the punching die is complex, and the manufacturing precision is required; 4. The surface integrity rate of precision stamping parts can reach level 1, generally level 2. The general burr height is 0.01mm to 0.08mm, and the consistency of the parts is good; 5. Although it can The design and manufacture of hydraulic fine-blanking dies are installed on ordinary punches or hydraulic presses to realize the fine-blanking process, but modern fine-blanking production uses high-precision special fine-blanking presses to achieve better results. Keep improving is the constant pursuit of people. Hardware, 15 years of focus on precision metal stamping parts, 20,000+ sets of customized stamping die production experience, monthly processing capacity of 100+ sets of molds, daily production capacity of 3 million punching times, stamping accuracy up to 0.01mm, 16 quality inspections are strictly controlled . Do every piece of metal stamping with your heart, is your great partner!
