O le mafuaʻaga e aʻafia ai le lelei o le oti casting

Taimi: 2020-06-04 Hits: 27

Le faʻaauau pea le atinaʻeina o saienisi ma tekonolosi, o manaʻoga mo oti-lafoina oloa ua maua maualuga ma maualuga. Mai le saogalemu ma le mafaufau lelei e maualuga mea manaʻomia. O le puleaina o le laualuga vevela o le oti-faaiuga lafo e taua tele mo le gaosia o le maualuga-lelei vaega oti-lafo. Le talafeagai poʻo le le talafeagai suia vaʻaia o le a taʻitaʻia ai foi i le faʻaletonu o le lafoina tulaga. I le taimi o le gaosiga faagasologa, o le lafo le deformed, ma faaletonu e pei o vevela vevela, suia tui, fafo atuatuvale, loto i totonu shrinkage cavity ma vevela vevela tupu. Ina ua matua suia tulaga suia, o le fesuisuiai i le gaosiga taamilosaga, pei o le faʻatumuina taimi, faʻamalulu taimi ma faʻasusu taimi, i ai ni tikeri eseese o aafiaga.

  Some die castings are not formed, and the cavity is not full

  Factors: 1. The temperature of the die-casting mold is too low; 2. The temperature of the molten metal is low; 3. The pressure of the press is too low; 4. The lack of molten metal and the injection speed are too high;

  Adjustment methods: 1. 2. Improve the die casting mold and the temperature of the molten metal; 3. Replace the high pressure die casting machine. 4. Add sufficient liquid metal to reduce the injection speed and increase the thickness of the feed inlet.

   1. The planning of die-casting parts. At the time of planning, extra attention should be paid to making the structure of die-casting parts as simple as possible under the premise of using the request. Otherwise, the shortcomings of die castings such as pits, pores, and cracks are simply presented. The standard requirements for Shenzhen aluminum die-casting are accurate and reasonable. Otherwise, it will cause unnecessary trouble for the planning and management of mold planning and processing. Many unqualified products will be produced.

   2. The structure of the mold, the processing accuracy and the selection of the mold data are also meticulous: aluminum alloy die casting is die-cast by the mold, and the selection of the mold data is also greatly related to the quality of the product. The mold structure is not good enough, and it is difficult to pass the product even if the measures are adopted technically.

3. O le faʻaititia o le lafo o faʻataʻitaʻiga faʻamaumauga: A o le faʻaititia o le tulaga o le lafoina faʻamaumauga e masani ona tuʻuina atu o se tutusa pasene poʻo se pasene ma se suiga suiga i le lautele, e tatau ona faʻaeteeteina faapitoa ile taimi o le maualuga-tonu oti oti . E manaʻomia le faia muamua o se suʻesuʻega faʻataʻitaʻi. A maeʻa ona mauaina ia faʻamatalaga i luga o le suʻesuʻega faʻataʻitaʻi, fuafua e fausia ni mea mo le tele o oloa.

   4. Preparation and implementation of technology: The preparation of die-casting technology is determined by the technical level of the operator, the quality of the mold and die-casting equipment. Nowadays, it is difficult for China to control the technical parameters of die-casting under the condition of die-casting equipment, which is stable, reliable and accurate.

O le lafo lafo o se vaega o le mamafa faaiuga. O le faʻamalosi o le masini faʻaie o le masini faʻamutaina oti faʻamau faʻapipiʻi i se faʻamau suia. O le apamemea, zinc, alumini (alumini uʻamea) ma isi uamea vevela i se suavai tulaga ua sasaa i totonu o le vaipuna o masini oti lafo. Masini oti lafo, lafo apamemea, zinc, alumini (alumini uʻamea) vaega ma le faʻatapulaʻaina foliga ma lapoa o le suia.
