The main material for manufacturing bulletproof helmets is the overlapping layer of UD cloth made from synthetic plastic fiber cloth called aramid or ultra-high molecular weight polyethylene fiber on the color cutting table. When a bullet passes through a tightly woven fiber cloth, the fiber cloth will dissipate a large amount of penetrating energy, thereby blocking the bullet.
The Production Process of Bulletproof Helmets
The main material for manufacturing bulletproof helmets is the overlapping layer of UD cloth made from synthetic plastic fiber cloth called aramid or ultra-high molecular weight polyethylene fiber on the color cutting table. When a bullet passes through a tightly woven fiber cloth, the fiber cloth will dissipate a large amount of penetrating energy, thereby blocking the bullet. The more layers of fiber cloth, the better the bulletproof effect of the helmet.
Then, on the surface of the stacked material, lay the designed drawings and use a band saw to cut the corresponding shapes. Put the cut fiber cloth into the mold press, cross the fiber cloth pieces on the mold, and then use high-temperature steam and 150 tons of pressure to fuse each layer of fiber cloth into the outer shell of the helmet. Due to the inability of the paint to adhere to the fiber cloth, it is necessary to apply a paint layer to the pressed outer shell as a surface layer. Then, manually trim off the edges around the helmet, and use a drilling machine to drill holes for installing the jaw strap and optical equipment guide rails.
Next, trim the helmet and add rubber edges, then paint it. After the paint surface is completely dry, the next step is the water transfer printing process, which can add a camouflage coating to the helmet. The specific operation is to first cut the five colors of transfer film, put it into a water tank, dissolve the film with a chemical spray and activate the adhesive, then immerse the helmet in the water tank and penetrate the transfer film. The transfer film will adhere to the surface of the helmet like oil stains.
Finally, the inner part of the helmet is equipped with adjustable straps, neck pads, and shock absorbing lining. The outer layer of the helmet is equipped with guide rails to install tactical equipment, such as searchlight gas masks, communication devices, and night vision goggles. This completes the production of a bulletproof helmet.
