High-frequency welded bellows-type protective cover

High-frequency welded bellows-style protective covers represent an advanced form of protective shielding. Below is a detailed introduction covering their features, technical parameters, manufacturing process, and application fields:

I. Features

1. No adhesive sections, excellent resistance to coolants:
   The absence of bonded areas eliminates issues such as adhesive aging or detachment, ensuring long-term resistance to coolant erosion and extended service life.

2. Durable against stepping and hard object impacts, deformation-resistant:
   High strength and toughness enable the cover to withstand external impacts and compression while maintaining structural stability.

3. No internal metal components, preventing machine damage:
   With no metal parts inside, there is no risk of loose components falling onto guide rails during operation, thereby avoiding severe damage to machinery.

4. Excellent sealing and smooth operation:
   Effectively blocks dust, iron chips, and debris from entering the machine. Low operational resistance ensures minimal impact on normal machine functions.

II. Technical Parameters

1. Standard fold height:
   Common specifications include 15mm, 20mm, 30mm, 35mm, 40mm, 45mm, and 50mm, with customization based on requirements.

2. Guide rail surface and shield spacing:
   Minimum 5mm, maximum 10mm.

3. Shield dimension relationships:

   • Expanded shield dimension = 2× fold height.
   • Compressed fold thickness: 4mm.

4. Customization options:
   Tailored parameters include extended length, compressed length, stroke length, total shield width, guide rail width, internal shield width, total shield height, guide rail length, and shield height on guide rails.

III. Manufacturing Process

The covers are produced using high-frequency welding technology, bonding an outer PVC/TPU-coated fabric with an inner PVC framework. This method ensures:

• High efficiency and speed.
• No adhesives required.
• Maintenance-free post-welding.
• Superior waterproofing, dust resistance, oil resistance, and acid resistance.

IV. Application Fields

1. Machine tool industry:
   Widely used in conventional machine tools, CNC machine tools, and hydraulic machinery to protect guide rails from dust and debris, extending equipment lifespan.

2. Automation equipment:
   Applied in automated warehouses, robotic arms, lifting/transport systems, and other automated devices to ensure stable operation.

3. Other industries:

   • Lifting platforms in automotive assembly lines.
   • CNC machinery, electronics, stone/glass processing equipment, door/window machinery, and injection molding machines.
