New Zealand H1 Glazing Requirements for IGU

New Zealand H1 Glazing Requirements: What They Mean for IGU Manufacturing For an IGU manufacturer, “H1-compliant glazing” is the start of a specification discussion. It does not yet identify the panes that a production line will handle. The factory still needs the glass build-up, coating, dimensions and processing requirements. The equipment supplier needs to know which of those panes—or which […]

Triple-Glazed IGU Production

Triple-Glazed IGU Production: Handling Conventional and Thin-Center-Pane Units A request to “handle triple glazing” leaves an important question unanswered: what is being lifted at that moment? It could be a conventional outer pane, a thin center pane entering the assembly line, or a completed insulating glass unit. The dimensions may be similar, but the contact surface, stiffness, mass and support […]

The Next Chapter for MTC

The Next Chapter for MTC: Making Surface Contact a Design Decision Imagine a glass-handling system being reviewed for purchase. Its payload and cycle requirements are clear. The discussion of surface quality, however, ends with a brief instruction: avoid visible marks. Only later does someone ask which glass surface will be contacted, when its appearance will be judged, and who decides […]

Flexible Mounting for Uneven Surfaces

Flat Oval Suction Cups with eT-Flex: Flexible Mounting for Uneven Surfaces In industrial vacuum handling, choosing the right suction cup is not always just about lifting capacity. For long and narrow workpieces, flat oval suction cups are often a practical choice. Their elongated gripping area provides stable contact while fitting into limited installation spaces. However, even when the suction cup […]

Why a Stone Slab Loader Loses Vacuum

Why a Stone Slab Loader Loses Vacuum: Cup, Surface and System Checks A stone slab loader that loses vacuum does not always need a different suction cup. A worn sealing edge is one possibility. An uncovered cup, a leaking connection or a different slab contact surface can produce a similar complaint. The most useful first step is to describe the […]

Suction Cup Marks on Quartz Slabs

Suction Cup Marks on Quartz Slabs: What Fabricators Should Check Before the Next Lift A ring appears on a quartz slab after handling. It follows the outline of a cup, but wiping the surface does not immediately explain what happened. Before changing the rubber or reaching for a stronger cleaner, establish when the mark appeared and what type of change […]

Replacing Suction Cups on Stone Slab Loaders

Replacing Suction Cups on Stone Slab Loaders: What to Measure Before Ordering The loader is ready, the next slab is at the rack, and one cup will not seal as it used to. The first purchasing question is often simple: “Can you supply another cup with this diameter?” A useful replacement enquiry needs a little more information than that. Replacement […]

Bellows Suction Cups Failing?

Why Do Bellows Suction Cups Keep Failing at the Same Position? Repeated failure at one position on a machine is a reason to investigate the local operating conditions, not just the replacement cup. Uneven compression, mounting alignment, sideways loading or release timing may expose that position to a different duty than the others. Local heat, chemicals and workpiece features also […]

Qualify a Second-Source Suction Cup Supplier

How to Qualify a Second-Source Suction Cup Supplier for Glass Processing Machines You have a quotation for a replacement suction cup. The dimensions look right, the price is reasonable, and the supplier says it can be used on your machine. Before placing the order, your maintenance team asks a fair question: how will it behave once it is on the […]
