随着国内塑钢门窗的普及使用,型材企业在行业几个大企业的带动下,近两年也取得了巨大的发展。但在产能迅速扩张的同时,型材产品的质量却没能取得相应的进步。各个地区分别出现型材变色、焊角炸裂等质量问题,使人们刚刚接受塑钢门窗的优点,又同时对它的质量持怀疑态度。行业协会和多数企业均意识到,出现质量问题的原因是:多数企业技术力量薄弱,对先进设备的驾驭能力不够,质量控制体系不完善,同时国内助剂发展速度缓慢,配方体系不科学,型材断面设计走小型化道路。
With the popular use of plastic steel doors and windows in China, the profile companies have also achieved tremendous development in the past two years, driven by several large companies in the industry. However, with the rapid expansion of production capacity, the quality of profile products has not been able to make corresponding progress. In various regions, quality problems such as profile discoloration and welding angle bursts occurred, which made people just accept the advantages of plastic steel doors and windows, and at the same time they were skeptical about its quality. Industry associations and most companies are aware that the reasons for quality problems are: Most companies have weak technical capabilities, insufficient ability to control advanced equipment, and inadequate quality control systems. At the same time, the development speed of domestic auxiliaries is slow, and formula systems are not scientific. Section design takes a small road.
