Coating Tech Slot Dies has parts and accessories available for any slot die coating system.

No matter the manufacturer, Coating Tech Slot Dies will promptly provide parts and service for any slot die and coating systems. Whether you need a standard part or something custom manufactured for your application, Coating Tech Slot Dies has the capabilities to promptly provide what you need to keep you operational and improve the performance of your coating line.

Slot die parts are often custom, and at Coating Tech Slot Dies we have developed a process to customize the parts you need regardlessof original slot die manufacturer or OEM to match your equipment at competitive prices.

Die Body Shims

Shims control the most critical component for slot die coating application – the slot gap.  The precision and flatness of the shim is important for optimum coating control.  Utilized in fixed lip slot die coating equipment, CTSD can provide a precision manufactured part for any slot die equipment that needs the functionality of a slot die body shim.

Slot Die Lip Adjusting Bolts

For flexible lip slot die coating equipment, the critical slot gap is controlled with lip adjusting bolts.  Typically utilized for hot melt adhesive coating applications, a flexible lip design requires understanding of the interaction between the lip hinge design, the adjustment rod, nut retainer and screw.  Whether the flexible lip slot die is a push only design or push/pull assembly, CTSD can provide a precision manufactured part for any slot die equipment that needs the functionality of a variable slot gap opening.

Slot Die Lip Inserts

In certain coating applications, the need for a removable lip insert can have great advantages.  For tensioned web over slot die coating, the final lip geometry cannot be determined until optimized through trial work; for research and development, different fluids may require different interfacial geometries for proper meniscus pinning; and for abrasive applications, repairing a damaged lip may be easier than refurbishing an entire slot die.  Whatever the reason, CTSD can provide a precision manufactured part for any slot die equipment that requires variable lip geometry within a set slot die design.

End Plates

Mostly for flexible lip slot dies, end plates allow for the adjustable lip to operate while maintaining a seal at the outer end of the slot die.  Typically utilized in combination with an end seal for hot melt adhesive coating, the end seal can also be utilized for a fixed gap slot die – the most precise way to manufacture a coating head.  CTSD can provide a precision manufactured part for any slot die equipment that requires maintaining the precision of the upper and lower die bodies from the ends of the equipment.

Seal Gaskets

Working in concert with the end plates, the gaskets seal off the manifold ends of the slot die.  Made from engineered polymeric material, the thickness, durometer and compression can match the need of the application.  Typically utilized in hot melt coating applications, this disposable part can be ordered in bulk and CTSD can match any slot die equipment that requires maintaining a seal during operation.

Adapter Blocks

(fluid delivery parts, sometimes referred to as entrance adapters) In the transition between the fluid delivery system and the slot die, the inlet adapter needs to be properly sized and manufactured.  Typically utilized for ambient temperature fluid coating applications, the transition can either be metal-to-metal or require a gasket in the transition.  Whether a welded sanitary fitting or threaded part is required, CTSD can design and manufacture the proper part required to handle the fluid and reduce the entrance of air into the system.
