Hot Melt Coating Machine

Trasy HMA Disc Applicator for making Anti Slip Heat Shrink Lables.

Trasy HMA Disc Applicator — retrofit glue applicator for shrink-sleeve lines. Apply ultra-thin, controlled EVA adhesive lines (10–15 µm) to the inside of PVC sleeves before seaming — no external heating, no film distortion. Fits existing center/seaming machines; available in single, double, or triple-line configurations.

The concept developed by Trasy Enterprises: — the rotating HMA disc approach (solid EVA-based discs, friction-heated on contact) is well suited for applying a very thin, localized glue line to shrink sleeves without externally heating the film.

Trasy HMA Disc Applicator (attachment for shrink-label center / seaming machines)
Solid EVA hot-melt discs rotate and press against the inner face of the PVC shrink film to deposit 1–3 parallel glue lines (10–15 µm) before center-sealing. No external heating of film; frictional heat softens HMA at the contact point only.

Application Range: Selective Coating, Dot coating, Pattern Coating on Film, Fabric, Textile, Paper & Lamination ...etc.

This coating can be done with various methods. Commonly it was done with reverse roller coating or gravure coating.  Gravure coating gives uniform coating but the disadvantage of this coating type is every time you have to change the engraved roller for different grammage of coating. In roller coating the challenge was to achieve thin coating and high speeds. The rotating roll churns the Hot melt and forms bubbles. This results in spotted coating.

In both these processes the molten adhesive is exposed to the air and loses its heat so the hot melt adhesive changes its viscosity and this results in variation of coating thickness. Normally the ends of the coating roll lose heat compared to the centre of the roll hence the coats more grammage at the sides and less at the centre of the web.  Sometimes the coating roller gives fumes due to high temperatures of the roller and thin layer of the adhesive on the roller hence the hot melt degrades due to high temperatures and loses its sticking property. 

Main features:1. To extend the design of the distance between the second unwinding and the composite makes the edge effect more ideal.Application:RTS hot melt adhesive lamination machine is mainly used in stickers products, such as stickers trademark paper, double-sided tape, foam tape, cloth tape , Kraft paper tape, the US profile paper tape, fiber tape, etc.Technical parameters:Coating width 400-2500mmCoated cloth amount 10-200 g / ㎡Coating speed 80 M / minUnwinding diameter 1000mmWinding diameter 1000mmCorrection device 1setsLength 8400mmHeight 2350mm

Main Characteristics :

• An AC converter control is used for both speed and quantity of glue feeding; the speed and glue feeding quantity can be adjusted manually or automatically.
• Adopt intelligent PID temperature control system, the temperature controlled exactly and the error is within 1 Degree Celsius.
• The glue melting tank is coated with the Teflon anti-sticking layer; it can prevent the hot melt adhesive against carbonization efficaciously.
• The precision metric gear pump on the machine can make it steadier to supply the adhesive.
• The high precision of alloy steel spray head can guarantee high quality coating result.
• The high efficiency cooling device insures the applicable range of the basic materials.

This machine is a hot melt adhesive coating machine. The machine has two heads of slot die coating and two melting units. This enables to coat on both sides of the substrate in a single operation. As a result, it gives double production and less wastage.

This machine is designed especially for making sticky insect traps. It has the capacity to hold 300mm wide rolls and coat up to 300mm wide. Along with double coating heads, it has 3 unwinds and 1 rewind.

Two unwinds hold rolls of the release liner. These liners are coated with slot dies. These slot dies are fed with molten glue by two independent melting units. Both melting units have gear pumps for the controlled, constant and measured flow of glue.

After coating on the release liners, both the papers are laminated with the PVC film sandwiched in between. This PVC film is dispensed from the third unwinder. After the lamination, all the three plies are wound at the winding station.

All the unwinders are equipped with magnetic powder brakes and web guiding systems. The rewind station has a magnetic clutch for a taper tension controlled winding.

In this type of coating procedure, the coating material is measured onto the applicator roller by precision setting of the gap between the upper metering roller and the application roller. The coating is 'wiped' off the application roller by the substrate as it passes around the support roller at the bottom. The diagram illustrates a 3-roll reverse roll coating process.Trasy Enterprises has developed a hot melt coating machine on this principle. The absence of solvents, volatile parts and water, offers an environmentally friendly operating process, and since no additional heating energy is required to evaporate water or solvent and the curing takes place by ambient air temperature or by the humidity of the ambient air, no drying or curing ovens are necessary.Application Range: Tapes, Laminates of Film, Fabric, Textile, Paper...etc.

Description :

This machine produces the Insect Sticky Traps. These glue traps are also called as pheromone traps as it attracts and traps flying and creeping insects & pests around your plants, fruits and vegetables. It is an effective product that works in the rain, sun or wind that requires no on-going maintenance, has no poison, no chemicals and no vapours or baiting. The Hot Melt Glue Trap is a bright yellow colour plastic sheet and is coated on both the sides with the special glue. This therefore sends out a unique colourful wavelength that attracts a broad range of insects. These may include fruit flies (both male and female), black flies, white flies, shaw-flies, mosquitoes, midges and the day-to-day small flying insects & pests. However, the Blue trap has some important advantages. As well as the blue being more attractive for the thrips; it is also far less attractive to other species. This increases the specificity of the traps and avoids the complications of attracting the non-target and in particular beneficial insects, which need to be preserved. The blue traps can comfortably be used in glasshouses. Here beneficial insects are being released. Some insects are still caught but this is likely to be due to random contact. Even in the most inclement weather it will remain active and useful for around three months. Blue sticky traps are a non toxic way to control and monitor Thrips & Leaf miners. As an integral part of integrated pest management program they can be used in commercial crops, green houses, homes, orchards, flower and vegetable gardens, anywhere insects are a problem. White sticky traps are a non toxic way to control and monitor Thrips, Leaf miners, Shore fly, Tarnished plant bug, European apple sawfly, Fungus, Gnats, Flea beetles. Raspberry beetle. Scale insects, Sciarid Flies, Nuisance flies.
