In addition, laser marking is also involved. , special equipment for production workshops such as safety protection equipment, material transportation and equipment.
In sheet metal production, software applications are mainly divided into three categories: business management software, engineering and workshop management software, and analog design software. The analog design software application ratio is up to 63%. By using CAD/CAE and other analog design software, the production line can be highly efficient and highly reliable, reducing the number of stamping processes and molds, improving product processability and material saving, thereby improving product quality. And the purpose of reducing costs. The ratio of engineering and workshop management software is 25%. Increasing the utilization rate of sheet metal enterprise management software is very important to improve the data control and management efficiency of production. This aspect should be paid attention to by the industry.
Nowadays, the low-cost advantage that the manufacturing industry relies on for a long time is disappearing, and the quality is gradually improved. It is an inevitable choice for the industry to realize the automation and flexibility of sheet metal equipment as soon as possible. According to statistics, flexible manufacturing technology integrating automation technology, information technology and manufacturing technology accounts for 14.50%. It liberates people from physical labor synchronized with machines, which is an inevitable trend of industry development. At present, the overall automation and flexibility of the domestic industry is not high, and the capacity of complete sets of lines needs to be improved. Many enterprises have begun to pay attention to R&D investment in this area.
Sheet metal enterprise procurement equipment attention to after-sales service
In the procurement and use of specific equipment of the panel processing enterprise, ensuring the continuous uninterrupted production of the equipment is the most demanded by the application enterprise. It is the key to the after-sales service of the equipment manufacturer to reduce the failure rate of the equipment and ensure the rapid and timely maintenance and repair of the equipment.
The survey results show that the production enterprises pay most attention to the timely maintenance and spare parts supply of the equipment in the after-sales service, with a concern of 62.60% and 38.93%. Compared with the main equipment, the company is more eager to provide 44.27 %, I hope that through the equipment manufacturer's training for the employees of the company, we will learn the technology in the true sense and ensure the uninterrupted operation of the production. According to this analysis, equipment manufacturers provide personnel technical training, Q & A will be an important trend for equipment manufacturers to win customers in the future after-sales service.
It can be said that for an enterprise, only according to market demand, continuously improve and improve product quality, strengthen after-sales service, establish and consolidate a good brand image, form a high quality credibility in the industry, and be recognized by users, in order to win High market share.
