I don't have time to translate for a long time, so I recommend a mechanical professional dictionary to a friend who plans to translate.

Devise. As the first step in sheet metal fabrication planning, it is beneficial to check whether a certain design feature is conducive to easing the manufacturing process. This inspection is also necessary to avoid manufacturing defects, component defects, and the need for new molds, tools, or machines. The size, position and external features of the internal structure such as holes, long holes, internal and external contours, shear, cuts, sleeves, cups, grooves and bending should be correctly tested according to the test specifications.

strip-layout is designed to arrange the layout of the operation and subsequently determine the number of sites required. The strip-layout is mainly governed by the geometrical characteristics of the part, the tolerance dimensions, the sharp edge orientation of the standing strip and other technical requirements. There is no particular solution for strip-layout in this important design, but it is generally accepted that this is some basic guidelines (Kumar, 2006).

strip-layout design.

As a first step, it is useful to check whether there are certain design features that are conducive to ease fabrication as part of the planning fabrication. This inspection is useful to avoid manufacturing defects, partial weaknesses, and the need for new molds, tools or machines. Dimensions and locations of internal and external features such as holes, long holes, interiors, external contours, cuts, cuts, cuts, bosses, cups, grooves and bends should be tested for good practice.

The strip-layout design arranges the assignments and subsequently identifies the needs of some stations. The band layout is mainly composed of part of the geometric features, tolerance dimensions, direction of the sharp edge strip and others.

Hot chamber die casting.

Hot chamber die casting is the main technology in the die casting production process. This section will focus on the differences between the specific details of the hot chamber die casting production process and the hot chamber die casting branch.

The process of the hot chamber.

Both die casting processes are characterized by the use of high pressures that force molten metal through molds called molds. The high quality of many castings produced by die casting, (such as large surface details), can be attributed to the pressure used in making the metal flow through the mold. Hot Chamber Die Casting Production**Metal adhesion to die casting machines is an integral part of foundry equipment for manufacturing operations.

The lens barrel injection stroke provides power. It is located at the ** of the molten plunger rod from the barrel under the plunger, which is in contact with the molten material. In the casting cycle, the plunger is at the top of the chamber to start (hot chamber) ingestion. The port allows the chamber to be filled with liquid metal.

When the cycle begins the power cylinder pushes the piston downward. The plunger cuts off the flow of molten metal in a hot chamber at the port. Now the correct amount of molten material in the chamber should be "shots" that will be used to fill the mold for the production of castings.

At this point, the plunger travels further down forcing the molten metal mold. Pressure is applied to hot chamber die casting manufacturing in molten metal filled molds, typically from 700 psi to 5000 psi (5 MPa to 35 MPa). The pressure remains fixed for a sufficiently long casting.

In the casting production of the plunger up through the heat chamber to expose the air inlet and fill the chamber with melt for the next cycle of preparation.

For a wider range of details in mold installation, the die casting process, or the performance of die casting mold manufacturing consider the basic process of casting.

Hot chamber die casting offers a high productivity advantage. One disadvantage of the industrial production process is that the mechanical device that requires a critical part of the installation, such as a plunger, must be constantly immersed in molten material.

At sufficiently high temperatures, these materials are continuously flooded to draw components associated with their failure resulting in thermal damage. For this reason, usually only low melting point lead, tin point alloys, zinc are used to manufacture castings with hot chamber die casting processes.
