Hot Melt Coater/Laminator

HLCL-1000

The HLCL-1000 is a precision laboratory benchtop Hot Melt Coater/Laminator capable of producing coated samples of hot melt adhesives, and then laminating to a variety of foils, films, and papers. Lab scale simulations of production processes can be easily set up and studied. The Hot Melt Coater/Laminator is designed to consistently coat hot melt formulations with the following features:

• Rugged construction, capable of withstanding the abuse of the production environment
• Aluminum frame, hard coat anodized and Teflon coated
• Precision ground, 303 stainless steel coating bars for highly accurate cross web coating
• Set the gap quickly with two feeler gauge sets, included with the machine
• Adhesive reservoir capacity up to 125 grams
• Reservoir is capable of maintaining temperatures up to 400°F (204°C)
• Coating range capable of producing 25 gsm to 1,500 gsm samples
• Produce samples of unlimited length from 3" (7 cm) to 12" (30 cm) in width
• 500-watt heating rods provide heating capacity to the reservoir and two coating bars
• J-type thermocouple is an integral part of each heating rod
• Reservoir and coating bar temperatures are accurately maintained by individual digital PID controllers
• Temperature controllers, heating elements and electronics are housed in a separate steel enclosure
• Heating elements connect to the control box with individual 36" (1 m) stainless steel armored cables
• Controllers are capable of maintaining temperatures to a tolerance of +/- 2°F (1°C)
• Quickly disassembles with a minimum of parts for easy cleaning
• Unwind stands are capable of holding roll stock up to 12" (30 cm) diameter by 12" wide (30 cm)
• Steel base assembly firmly supports the coating head and unwind stand
• Adjustable Teflon side dams allow for coating control from 1/2" to 12" in width
• Friction type brake unwinds on both liner and face material
• Simple pivot mechanism on unwinds allow for basic web alignment
• Top and bottom laminator rolls are 2" (5 cm) diameter by 24" (61 cm) face width
• Top and bottom laminator rolls have a steel core and are covered with 80 durometer silicone rubber
• Bottom laminator roll is driven, top roll idles
• Requires compressed air - max pressure 90 PSI (6 bar)
• Air pressure is adjustable for differing levels of laminating pressure
• Laminating pressure (LP) can be approximated using the following formula: LP = (3.4 x line pressure) / sample width
• Flow controls are included on both laminator cylinders to allow for smooth, safe operation
• Safety features include appropriate guarding and an emergency stop switch
• Variable speed motor allows coating / laminating speeds from 0.5 to 7.5 fpm (0.15 - 2.25 mpm)
• Standard input voltage - 120 VAC (50/60hz)
