Pearl cotton profile design quadripartite

152次浏览分类:行业知识 2019-12-21 152 views categories: industry knowledge

The pearl cotton profile contains damping and is an ideal vibration and shock-proof material. It is widely used in the packaging of craft products such as home appliances, consumer electronics, precision machinery, and vehicle electrical appliances. The design principle of EPE profile is to design according to the buffer requirements, and then check its shock resistance. The following are the four steps in the design of pearl cotton profile by the staff of Zhengzhou Hongfeng Plastic Packaging:


珍珠棉异型材设计四部曲


   1. Preliminary design of pearl cotton profile:

EPE 材料,确定出合理的结构形式和尺寸 ; The basic requirements for the design of EPE profile are to select the appropriate EPE material under the premise of protecting the product from damage and determine a reasonable structural form and size ;


   2. Equivalent drop height of pearl cotton profile:

; Equivalent drop height The magnitude of the impact energy of the instrument package during the circulation process is mainly caused by human and mechanical operations during the loading and unloading process, and its energy level should be determined based on factors such as product weight, volume, belt height, and personnel height ;


   3 , the determination of product brittleness value of pearl cotton profile:

Through the crispness test, the allowable crispness value of the product is determined based on the value, strength deviation, importance, and the risk of product damage during transportation. This is the main method of product crispness. ; In addition, the crispness of the product can also be determined by the standard value of the crispness value and the theoretical estimation method ;


   4 , check of pearl cotton profile:

The design made according to the basic design must actually be checked in many aspects and made some additional adjustments:

   ; -The check of the strength is to lower the force on the product and the strength of the product ;

   1.33 倍的 2 次方 ; -Deflection check, the ratio of the size, area and thickness of the pearl cotton profile should conform to the Kestner empirical formula, that is, the minimum area should be greater than the power of 1.33 times the thickness ;


The four steps of the design of the pearl cotton profile are believed to be basically understood by the above sharing. EPE 包装过程中,因国内总体流通环境条件的差异和技术手段的落后,大多时候使用的等效跌落高度在 800MM-1000MM 范围内确定。 In addition, in the actual use of EPE packaging, due to differences in the overall domestic distribution environmental conditions and backward technological methods, the equivalent drop height used in most cases is determined within the range of 800MM-1000MM .
