Three Methods of Manufacturing Square Conical Protective Guards:

Flexible accordion-style protective covers are a customizable product line, with the raw materials, shape, processing methods, and dimensions all adjustable according to actual needs.

A fundamental component is the inclusion of a PVC support frame within each fold-out section, which can be securely attached to the exterior fold-out material via various processing methods.

A stitching method for high-temperature work environments, utilizing a special thread for durability and strength even under load.

The PVC frame is stitched to each fold for reinforcement and stability of the guard. Additionally, a variety of materials are available for your selection.

2. One method is thermal bonding. At a certain temperature, with the help of a special flux, the internal PVC frame can be firmly bonded to the external fold pages.

If the hood is used in a medium-temperature environment, this method can be chosen.

3. One method involves high-frequency welding the outer PVC/TPU coated fabric and the inner PVC frame using a high-frequency welding machine, ensuring high efficiency, speed, and the elimination of any need for additional adhesive.

This high-frequency welded shield *requires no maintenance and is waterproof, dustproof, oil-resistant, and acid-resistant.
