Slotted Loop does not have ordinary and non-ordinary classification methods, only metal and non-metal, cheap and not cheap. Of course, metal and non-metal Slotted Loop can be divided into a variety of materials. So we started the topic of Slotted Loop and discussed why some products like to use metal Slotted Loop, and some products like to use plastic Slotted Loop. What factors are related to whether Slotted Loop can be used after being disassembled many times.

Slotted Loop is a mechanism for inserting connection or integral locking between one part and another part. It is usually used for the connection of plastic and plastic, or the connection of plastic and metal. If it is a metal-to-metal connection, Slotted Loop is generally not used. The reason why Slotted Loop is chosen for connection when assembling the whole vehicle is because the clamping process is very simple, and a well-designed clamping process requires almost no auxiliary tools. If you only design some parts as a whole, on the one hand, they are too bulky and difficult to transport, and on the other hand, if some sub-parts need to be assembled in the parts, it is not easy to operate, so simply design several sub-parts to snap together, which is convenient for transportation , It is convenient to disassemble the sub-parts and saves the cost. More than 70% of the common Slotted Loops are made of plastic materials, and less than 30% of Slotted Loops will choose metal materials. This is because:

1. The density of plastic is much lower than that of metal. Although we can’t see it with the naked eye, there are actually hundreds of Slotted Loops in the entire vehicle. If these Slotted Loops are all made of metal materials, the total amount will reach several kilograms, and plastic materials will reduce some weight. .

2. The molding process of plastic Slotted Loop is much simpler. Most of the plastic Slotted Loops are injection molded at one time. Of course, with the advancement of technology and considering the noise reduction factor, many Slotted Loops now also use two-shot injection molding of a piece of EPDM material for cushioning at the front contact points. However, the process of metal Slotted Loop is more complicated, including cutting, punching, bending and other machining processes, as well as surface treatment processes. It can be seen from the screenshot that such a simple metal Slotted Loop requires seven different tools to be operated in sequence through the program, while injection molding only requires one mold and one step to form, so the molding process of plastic Slotted Loop is simpler.
