Stamping

Mesin hot print merupakan salah satu mesin yang dapat digunakan untuk melakukan teknik emboss pada beberapa objek yang bisa di emboss. Biasanya mesin hot print  juga sering disebut sebagai mesin hot stamping foil, karna mesin ini memakai foil warna dalam proses pengembossan nya. Mesin hot print ini dapat menghantarkan panas pada objek yang dituju seperti kulit, kertas, bahan PVC dan bahan-bahan yang lain sebagainya.

The present work studies the effect of over-rolling performed on a skin-pass mill on the drawability of a Ti-stabilized IF steel. Tests have been carried out with increasing skin-pass reductions (up to about 1%) and the corresponding mechanical properties, microstructures, textures and related forming limit curves (FLC) have been assessed. The results have shown that the yield strength increased, the strain-hardening coefficient (n) decreases, with increasing skin-pass over-rolling. The FLC results presented results where the scatter showed no marked effect, for the studied range of over-rolling.

We hereby declare that the thesis project entitled "DESIGN AND SOFTWARE IMPLEMENTATION OF EXAM PAPER ATTACHING MACHINE" submitted for B. Sc. Degree in electromechanical is our original work and the thesis project has not formed the basis for the award of any degree, associate ship, fellowship or any other similar titles.

High-velocity electromagnetic sheet-metal forming and processing has many potential advantages over more conventional techniques, including: higher-forming limits, resistance to wrinkling and springback, one-sided tooling, and physical contact to only one side of the work piece. Traditional electromagnetic actuators are flat spirals that produce a nonuniform pressure distribution, limiting the types of parts that can be formed. A new type of electromagnetic actuator, the uniform pressure (UP) actuator, has been developed. The UP actuator can uniformly and efficiently accelerate conductive sheet metal to velocities on the order of 200 m/s or greater over distances of a few millimeters. When the material is arrested by impact with a tool, high-forming pressures can be imparted to it. The utility of the UP actuator is illustrated here by demonstrating its ability to form sheet metal components with intricate shape, to shock harden, and also to pick up nearly arbitrarily small details from a die surface. Thus, electromagnetic processing with the use of the UP actuator offers the unprecedented ability to simultaneously form and engineer the surface morphology and microstructure of sheet metal samples.
