Aluminum die casting defects and their causes

2024-12-10

The three elements of die casting die casting machine, die casting alloy and die casting mold is the three elements of die casting production, one cannot be missing. The so-called die-casting process is the three elements organically and comprehensively, so that it can be stable rhythmically and efficiently produce the appearance, good internal quality, size in line with the drawings or agreement requirements of the castings. Company inspection standards 1, controlled information: drawings, quality control table; 2, the national standard, the standard (JIS die casting standard); 3, customer limit samples die casting size is prone to changes in the parts: 1, slider 2, core 3, the size of the parting surface, 4, the top rod (the company's internal most economical guidelines, special requirements exceptions) inside the surface of the top rod relative to the casting body can be raised or concave 0.30MM inside and outside surface The top bar (polishable part) can be raised or recessed by 0.30mm relative to the casting body.

Differential pressure casting process and principle

2024-11-27

What is differential pressure casting? Differential pressure casting (also known as counterpressure casting), is the liquid metal in the differential pressure, filled to a certain pressure in advance of the casting, crystallization, solidification and obtain castings of a process. It is a combination of two processes: low-pressure casting and crystallization and solidification under pressure. The process can be based on the shape of the casting, process requirements and casting characteristics, adjust the pressure in the cavity, so that the liquid metal flow into the casting under control, and in the casting does not change the state of the casting force conditions, so that the casting solidified under higher pressure, the production of other forming methods difficult to pour complex, thin-walled, whole aluminum castings, to solve the casting casting technology in a major key.

Shaped parallel groove wire clips

2024-11-25

During the installation and operation of a tie line tower, the pulling force of the tie line needs to be precisely adjusted to ensure that the force is in a balanced state. In order to facilitate the installation and subsequent adjustment of the cable, adjustable cable clamps are usually placed in the area around the lower extension of the cable. Adjustment of the tie line can be accomplished with the aid of either basket screws or wedge-shaped UT-shaped tensioning clips, although the use of basket screws for adjustment of the tie line in towers has become less common in today's line conditions. The wedge-shaped UT-shaped tensioning clamp consists of a wedge mother, a wedge and a long U-shaped screw with a certain adjustment range. These clamps are not only used for stabilizing the tension wire, but also for adjusting the length of the wire and are suitable for the installation of GJ-25 to GJ-70...

NLL-2 Tension Clamp

2024-11-21

　Tension clamp (tension clamp, strain clamp, dead-end clamp), as an important fixture, is mainly used to fix the wire, so that it can withstand the wire tension, and the wire is properly hung to the tensioning string or tower. From the point of view of the structure and installation conditions, tensioning wire clamps can be roughly divided into the following two categories: non-conductive detachable tensioning wire clamps This type of tensioning wire clamps need to withstand all the tension of the wire or lightning line. The clamp holding force is required to be not less than 90% of the rated tensile strength of the installed conductor or lightning conductor, and does not function as a conductor of electricity. A significant advantage is that this type of wire clip can be removed after completion of the wire installation for separate use in other applications. Common types of this type of wire clip include bolt type tensioning clips and wedge type tensioning clips. Screw...
