Product Overview

The Vacuum Pad Sponge Type is a specialized workpiece retention solution designed to prevent drops during suction conveyance, especially when handling irregular or uneven surfaces such as external building walls, small stones, and seashells. Its primary function is to securely hold lightweight or fragile materials in place using vacuum suction, ensuring safe and stable transfer without slippage or damage.

Construction and Materials

The pad is constructed from either chloroprene rubber or silicone rubber, both selected for their durability and performance under dynamic conditions. The seal rubber material uses low concentration ozone-resistant HNBR or FKM, compliant with food safety standards including Japan's Notification No. 370 for food and food additives. Silicone rubber specifically offers high mechanical strength, abrasion resistance, and long-term durability, while its high density minimizes distortion under compression.

Configuration and Connections

The vacuum pad is available in a wide range of sizes: φ10, φ15, φ20, φ25, φ30, φ35, φ50, φ70, and φ100. Each size is designed to match specific workpiece dimensions or application requirements. The pad holder features multiple connection options including barb fittings (φ3x2, φ4x2.5, φ6x4, φ1/4"x0.18", φ1/4"x0.16") and threaded interfaces such as female threads (M5x0.8, M6x1, M8x1.25, G1/8, 1/8-27NPT) and male threads (M8x1.25, M10x1.5, M12x1.75, M14x1, M14x2).

Operating Characteristics

The pad is engineered for reliable performance on uneven surfaces, making it ideal for use with materials like building exteriors, small stones, and seashells where traditional flat pads may fail. It is specifically suitable for suction conveyance of food-related workpieces due to its compliant seal material and absence of copper-based metallic components in flow paths, ensuring safety in food-grade applications.

Sizes and Options

Available in multiple sizes from φ10 to φ100, the vacuum pad offers flexibility across a range of industrial and commercial use cases. The pad holder itself has a nominal internal diameter of φ1.6 mm when used without a pad, enabling compatibility with various suction systems and mounting configurations.

Installation and Integration

The product integrates directly into existing vacuum systems via its threaded or barb-fitting connections. Compatible male thread options include M8x1.25, M10x1.5, M12x1.75, M14x1, and M14x2, while female threads such as M5x0.8, M6x1, G1/8, and 1/8-27NPT ensure secure attachment to a variety of vacuum equipment or conveyance systems.
