What kinds of processes are there for trimming the Automotive Wiring Harness Protection Sleeve?

There is a trimming process in the production process of Automotive Wiring Harness Protection Sleeve. The purpose of trimming is to make the product surface smoother, cleaner in appearance, and reduce the impact of irregular burrs on the sealing effect. There are three main trimming methods currently used, namely manual trimming, mechanical trimming, and frozen trimming.

1. Mechanical trimming
Compared with manual work, machinery has made corresponding improvements in efficiency and quality. Generally, rotating blades are installed on trimming machines, and there are corresponding standards for matching blades with product dimensions. Some also have secondary trimming to prevent the first trimming from being incomplete. The high completion rate of mechanical trimming has greatly improved the production efficiency of Automotive Wiring Harness Protection Sleeve, and the trimming device can also be integrated with the entire production device.
2. Frozen trimming
In fact, frozen trimming is also a kind of mechanical trimming, but the working environment is different. It is carried out in a frozen environment. First, the finished product is frozen with a freezing medium, and then four edges are performed using mechanical equipment. This method originates From Japan. The key to this technology lies in the choice of freezing medium and the timely update of equipment
3. Manual trimming
Manual trimming means that workers use corresponding knives to manually remove the burrs on the outer edge of the Automotive Wiring Harness Protection Sleeve. This is also the most primitive method. The quality of edge trimming mainly depends on the experience accumulation of workers. The edge trimming effect is unstable and the efficiency is relatively low. And it is easy to damage the product to produce gaps and scratches, resulting in leakage during use.
