Flame-retardant accordion-type protective cover

Flame-retardant accordion protective cover features:

1. These protective guards feature features such as being resistant to foot traffic, not deforming from impacts by hard objects, long service life, good sealing, and easy operation.

2. The accordion-style protective cover has a long stroke and minimal compression, with a length ratio of 1:10.

3. The distance between the guide surface of the machinery and the guard is between 5mm and 10mm.

4. The dimension of the shield when the pleated surface is opened is equal to one times the height of the pleat, with a compressed pleat thickness of 4mm.

5. Standard Crease Heights: 15mm, 20mm, 30mm, 35mm, 40mm, 45mm, 50mm.

6. The product uses materials that are resistant to coolant, oil, grinding wheel swarf, and iron slag, etc.

7. The advantages of a long stroke and small compression for protective guards.

8. The speed of the blower in the guard shield can reach up to 200m/min.

9. The guard housing contains no metal parts, so there's no need to worry about loose components during operation that could cause severe damage to the machine.

Three Methods for Manufacturing Flame Retardant Convoluted Protective Hoods:

A fundamental component includes a PVC frame within each fold, which serves to support and stabilize, tightly connected to the external fold materials through various processing methods.

A stitching method for high-temperature working environments, utilizing a special thread that remains sturdy and durable even under load.

The PVC frame is stitched into place on each fold to reinforce and stabilize the shield. Meanwhile, 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 folding pages.

If the shield is to be used in a moderate temperature environment, this method can be chosen.

3. One option involves high-frequency welding of the outer PVC/TPU coated fabric and the inner PVC frame, offering high efficiency, speed, and the need for no additional adhesive.

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

*Features: Features include tight and reasonable structure, noiseless operation, large stroke, fast movement, and long service life. Widely used on general machine tools, CNC machine tools, hydraulic machinery, and other equipment.

Our accordion protective cover equipment can also be made with steel support frames, wooden frames, PVC frames, cold-rolled steel frame accordion covers, and more.

Based on the operating environment of the equipment, the internal structure of the accordion-type guard features grooves, roller, nylon sliding plates, sliding blocks, tension rods, tension springs, and nylon shafts.
