Requirements and indicators of glass production process for glass machinery

by:Enkong     2021-04-03
There are countless applications of glass products in our lives, and people’s increasing living standards have put forward higher requirements for the quality and craftsmanship of glass products. The melting process is not only to ensure the quality of glass packaging, but also a key link in the greening of glass packaging. The glass melting process can be roughly divided into five stages: silicate formation, glass formation, clarification, homogenization, and cooling. The melting process adopts continuous operation, these 5 stages are carried out in different parts of the furnace, so as to control the accurate melting temperature in sections. The stability of the kiln operation process index is very important. Generally, it is required that the melting temperature fluctuation does not exceed 10℃, the liquid level fluctuation does not exceed 0.5mm, and the kiln pressure fluctuation does not exceed 2Pa to prevent fire in the kiln space, thereby preventing quality problems such as stones, color, appearance, and poor strength. For different products, it is the key to determine reasonable parameters through experiments. Advanced bottle making, feeding and heating systems and the use of advanced molding processes are the fundamental guarantee for achieving uniform wall thickness and achieving lightweight.
The output value of glass machinery increased significantly year-on-year
Numerical control processing is the trend of high-quality, high-precision, high-yield, and high-efficiency development in the machining industry. The outstanding development trend of our country's glass edging machine shows that the demand is still at a high level. Related companies should seize the opportunity and strive to complete the change of glass edging machine products from low-end to high-end, from primary commodity processing to high-precision commodity manufacturing, as soon as possible. The development of glass edging machines will also effectively complete the transformation from a large country of glass machinery production to a powerful country of glass machinery. In the first two months of this year, the sales of the glass edging machine industry were basically the same year-on-year, but the glass machinery industry declined year-on-year and did not bottom out. Since January last year, orders in the glass machinery industry have continued to increase for twenty consecutive months, and the lack of orders is still the most important question in the industry. The turnover of domestic exhibitors at this year's exhibition of glass machinery decreased by 40% compared with that of glass machinery last year. During this period, the turnover of the glass machinery industry decreased by 40%, and the turnover of glass edging machines decreased by 40% year-on-year, reflecting the situation in the first half of this year. There will be no significant improvement. In addition, corporate profits have decreased and fluctuates more. In the first two months, the profit of the glass machinery industry fell by half year-on-year, and the company's losses have exceeded 60%. This year, glass machinery has changed the trend of continued decline in the output value of the previous year. In the first quarter, the initial value of our country's glass machinery output increased by eight percentage points year-on-year. In March, the initial value of our country's glass machinery output increased by 16% year-on-year, the highest value in a year. The output value of glass machinery increased significantly year-on-year, with a year-on-year increase of 15%.
