Machine safety protective cover Lamellas

fire-resistantcustom-mademodular

Product Overview
The Lamellas (armor-type covers) are composite protective covers combining a flexible pleated inner bellow with external metal lamella plates. Positioned between standard bellows and telescopic steel covers, they are designed for heavy-cutting and high-temperature chip environments.

Materials & Design
Outer lamella plates: stainless steel 201 or 304
Inner bellow fabric: PVC-coated, PU-coated, aramid flame-retardant, TPU, etc.
Structure: Flexible pleated body + metal lamella composite; configurations: Roof-type, Full-enclosure, Z-shaped
Mounting: Flange

Key Performance Parameters
Operating temperature: −20 °C to 50 °C
Instantaneous surface temperature resistance: ≤ 600 °C
Maximum travel speed: ≤ 120 m/min
Lamella thickness options: 0.3 mm, 0.5 mm
PVC support plate thickness options: 1.0 / 1.5 / 2.0 mm (others on request)

Structural Comparison (lamella mounting)

• Fixed lamella plates: Riveted to PVC support plate; multi-layer tight closure; suited to horizontal motion; individual plates replaceable.
• Hinged lamella plates: Hinged installation allowing plate lift; optimized for limited vertical space and vertical motion; easy to install.

Configuration Comparison (outer structure)

• Roof-type: Inclined layered plates with support frame; focuses on shedding frontal chips and impact resistance.
• Full-enclosure: Closed metal frame around laminated sheets; multi-directional protection and improved sealing.
• Z-shaped: Compact multi-facet design; maintains tight closure at bends; suited to constrained or complex machine geometries.

Commercial Information
MOQ: 1 piece; fully customizable: overall dimensions, lamella thickness, flange, mounting type (fixed/hinged), configuration (Roof/Full-enclosure/Z-shaped), inner fabric selection and optional accessories (flange connecting plate, slider, roller, limit strap, spring leaf).

Product Description
Lamellas combine the compression ratio of a bellow with the impact resistance of steel covers. The outer metal lamella resists high-temperature chips and prevents sharp fragments from cutting the inner fabric, extending service life in harsh machining conditions (heavy cutting, high coolant flow, chip splash). The inner fabric can be specified for high-temperature and flame-retardant performance. Modular lamella design allows replacement of damaged plates locally, lowering maintenance cost and overall moving load compared with monolithic steel covers. Noise levels are reduced relative to some steel covers, and the product supports travel speeds up to 120 m/min.
