The adaptability of sand cutting is very wide
Release time:
2024-01-29
Sand cutting mold, general wood production, commonly known as wood mold. In order to improve the dimensional accuracy is higher, but also often use a longer life of aluminum alloy mold or resin mold. Although the price has increased, but still much cheaper than the metal cutting mold, in the small batch and large production, the price advantage is particularly prominent.
Metal Type Cutting
Metal cutting (metal casting) is the metal smelting into a liquid that meets certain requirements and poured into the mold, after cooling solidification, cleaning treatment to get a predetermined shape, size and performance of the casting process. Cutting blanks because of nearly forming, and to achieve the purpose of no machining or a small amount of processing to reduce the cost and reduce the time to a certain extent, cutting is one of the basic processes of modern machinery manufacturing industry.
Focus on hot spots
Congratulations on the official release of the website of Jinan Longao CNC Machinery Co., Ltd!!!
Jinan Longao CNC Machinery Co., Ltd. is an enterprise dedicated to the design, development and production of precision CNC engraving equipment. Over the years, remarkable achievements have been made in the research and development and production of precision machine design and engraving technology, and the product quality has passed the EU CE certification and has been widely recognized.
The cutting performance of metal includes: ① fluidity, the ability of liquid metal to fill the mold; ② shrinkage tendency, large volume shrinkage from liquid to solid, easy to produce defects such as shrinkage cavity, and large linear dimensional shrinkage, which affects the final dimensional accuracy of castings; ③ hot cracking tendency, some metals and alloys are prone to cracks and segregation tendency in the cutting process.
Mold (liquid metal into a solid casting container) preparation, mold according to the materials used can be divided into sand, metal, ceramic, mud, graphite, etc., according to the number of use can be divided into one-time, semi-permanent and permanent, mold preparation is the main factor affecting the quality of castings
Gravity cutting
It is widely used in the production of various non-ferrous castings, but metal mold cutting also has the disadvantages of low metal utilization rate, difficult pouring of thin-walled complex castings, and low relative pressure cutting of casting tissue density.
When using metal type cutting, the following factors must be considered
When using metal type cutting, the following factors must be considered comprehensively: long manufacturing cycle, high cost, not suitable for single-piece and small-batch production; It is not suitable for cutting complex shapes (especially inner cavities), thin-walled and large castings (metal molds are limited by the size of mold materials and the ability of cavity processing equipment and cutting equipment, so metal molds are not suitable for the production of particularly large castings). The mold is more expensive than sand mold and cheaper than die casting.
