Overview

This technical catalog from Morali Produktionstechnik GmbH specializes in vacuum and gripper technology products, focusing on vacuum cups and fittings for industrial handling applications across sectors such as printing, packaging, plastics, solar cell manufacturing, semiconductors, and fine mechanics.

1. Product Categories and Materials

The catalog covers a broad range of vacuum cups including flat vacuum cups, bellows (Multiflex) suction cups, rectangular and oval cups, and specialized lines such as SolarVac, Praline VAC, and MiniVac. Materials used span TPU, PU, NBR, silicone, natural rubber (NR), EPDM, FKM (Viton®), chloroprene (CR), and polyurethane, with shore hardness values typically between 30° and 60°. Weight and thickness vary according to size and application.

Key Material Properties:

• Shore hardness ranges from soft (around 30°) to harder variants (up to 60°).
• Material selection is critical for chemical resistance, softness, antistatic properties, and surface compatibility.
• Custom materials and variants are available upon request.

2. Vacuum Cup Product Lines and Specifications

2.1 Flat Vacuum Cups (VAC Lines E, F, G, H, M)

• Sizes range from 5 mm up to 150 mm diameter.
• Variants include cleated cups for enhanced stability and cups designed for irregular surfaces such as corners and edges.
• Stroke lengths vary from 0.0 mm to 10.0 mm, accommodating different surface profiles.
• Connection threads include metric (M5, M6) and G-threads (G 1/8", G 1/4", G 3/8") with internal (IG) and external (AG) options.

2.2 Bellows Vacuum Cups (VAC Lines I, J, K, L, N and Multiflex)

• Diameters range from 10 mm to over 200 mm.
• Bellows design allows stroke compensation from 0.1 mm up to 40 mm depending on fold count and size.
• Weight ranges from under 1 gram for small cups to over 860 grams for large industrial sizes.
• Thread types and sizes vary to ensure compatibility with diverse vacuum systems.
• Some models include mesh (Sieb) filters for specific applications.

2.3 Specialized Lines

• SolarVac: For ultra-thin, fragile materials like solar cells and wafers, primarily using natural rubber with 40 Shore hardness.
• Praline VAC: Tailored for confectionery products, offering soft and specialized rubber variants.
• MiniVac: Designed for very small, lightweight components in fine mechanics, available in NBR and silicone.
• Grabber Cups: Manual vacuum cups providing strong holding force without vacuum pumps, suitable for glass, wood, plastics, and metal sheets.

3. Fittings and Accessories

• Wide range of fittings with male (AG) and female (IG) threads in metric and imperial sizes (M3, M5, M6, 1/8", 1/4", 1/2", 3/8", G 3/8").
• Accessories include retaining rings (Haltering), reinforcement rings (Versteifungsring), and plunger valves (Tastventil) to enhance stability and functionality.
• Some fittings incorporate mesh filters to protect vacuum systems.

4. Technical Specifications and Ordering Information

• Each product listing provides detailed parameters: diameter, weight (grams), stroke/hub length (mm), thread type and size, and article numbers for ordering.
• Thread types are clearly distinguished as male (AG) or female (IG) with standard industrial sizes.
• Ordering requires specifying the material code (e.g., 01 = NBR, 02 = Silicone) and article number to ensure correct product delivery.
• Packaging units vary, commonly 10 or 100 pieces depending on product type.

5. Application Areas and Recommendations

• Vacuum cups are suitable for handling flat, slightly curved, irregular surfaces, corners, and edges.
• Bellows cups provide stroke compensation to adapt to surface irregularities, with fold count influencing flexibility.
• Material choice should consider chemical resistance, softness, antistatic needs, and surface compatibility.
• Retaining and reinforcement rings improve mounting stability and prolong product life.
• Manual grabber cups offer strong holding force without vacuum sources for versatile handling.
• Users should match cup diameter, stroke, and thread type to their vacuum system and application requirements.

6. Summary of Critical Parameters

• Diameter Range: From very small (5 mm) to very large (up to 450x156 mm for rectangular/oval cups).
• Weight Range: From 0.1 grams (mini cups) to over 3800 grams (large oval cups).
• Stroke Range: 0.0 mm (rigid cups) up to 40 mm (large bellows cups).
• Thread Types: Metric (M3, M5, M6, M8, M10) and G-threads (G 1/8", G 1/4", G 3/8") with male (AG) and female (IG) options.
• Material Codes: Standardized codes for ordering (e.g., 01 = NBR, 02 = Silicone).
