Coating Applicator

molde : NCAF Film Coating

Ⅰ. DESCRIPTION
  • - The NCAF Non-atomized film dispensing automatic gun makes a high cycle efficiency.
  • - Fast trigger cycle capability ※ Trigger on/off Responding-Time: each 12-14(ms) @65psi
  • - Consists of air-actuating parts that air piston with needle travelling and micro-adjuster for precision dispensing
      pattern & thickness control
  • - Constructed of stainless steel 316
Ⅱ. BASIC OPERATION
  • NCAF-gun is triggered, the gun actuator simultaneously opens up air-passage and compressed air enters into the air cylinder through PT1/8” swivel elbow.
  • This air lifts the piston assembly and allows the packing cartridge / needle to rise.
  • The coating material enters into gun cavity thru PT1/4” fluid fitting then passes thru the opening of the gun orifice in the needle seat of the gun extension.
  • Air pressure removed, the needle returns back to the needle seat and stops the flow of material.
Ⅲ. FEATURES & BENEFITS / NCAF-gun
  • Higher than 99% transfer efficiency results in better material utilization, less waste, cost savings.
  • Virtually eliminates masking works and reworks thru precise, selective coating application.
  • Finish coatings even the complex circuit boards in several seconds.
  • Reduced VOC emissions thru use of a non-atomized application process
Ⅳ. FEATURES & BENEFITS / NCAF-gun
  • - Film pattern width recommendable: 6.0(mm) to 12.5(mm) ex.) Humiseal1B31 x 50(cPs)
  • - Material viscosity: under 100(cPs) in general
  • - Application thickness : 0.5(mil) to 5(mils)
  • - Edge tolerance: +/- 0.5(mm)
  • - Transfer efficiency : better than 98-99(%)
  • - Coating velocity recommendable : 150~400(mm/s) ※ Range available 100~500(mm/s)
  • - Typical fluids dispensing pressure : 10~50(psi) ※Pressure Vessel Based
  • - NCAF-gun actuating air-pressure appropriate : 70~80(psi)
  • - NCAF-gun pure weight: 540(gram/set)

    Mounted on Five(5)-Axis Cartesian Robot
Ⅴ. FILM NOZZLES / FCN series
Dispensing Nozzle Film Width Useful
AR1B31 / 30(psi) / 50(cPs) @12.5(mm) Away		 Section of Orifice (in ㎟)
FCN25 (Film-Pattern, Narrow) 7.5 (mm) 0.025
FCN50 (Film-Pattern, Medium) 10.0 (mm) 0.050
FCN60 (Film-Pattern, Wide) 11.5 (mm) 0.060

※ Note : Three(3) categorized film nozzles for the conformal coatings are available.

  • The head P/N (part number) begins with FCN represents Film Coating Nozzle standard while the following two digits number nominates actual section area of each film nozzle orifice.
  • The listed nozzles above can meet the film pattern width in a range of 6(mm) to 12.5(mm) appropriately depending on applied materials

molde : NCAS Spiral Spray Coating

Ⅰ. DESCRIPTION
  • - The NCAS Atomized spiral spray coating gun adopts S6CN nozzle to apply the materials that heating unnecessary
      and it is basically pneumatic powered spiral dispensing which depends on curved vortex air-holes in the nozzle.
  • - The NCAS-gun module consists of air cylinder, air piston and various air / fluid seals. It has micro-adjust mechanism
      to control piston travelling and needle-seat opening.
  • - The NCAS-gun makes high cycle efficiency.
  • - Fast trigger cycle capability ※ Trigger on/off Responding-Time: each 12-14(ms) @65psi
  • - Constructed of stainless steel 316
Ⅱ. BASIC OPERATION
  • NCAS-gunis triggered, the gun actuator simultaneously opens up air-passage and compressed air enters into the
    air cylinder through PT1/8” swivel elbow.
  • This air lifts the piston assembly and allows the packing cartridge / needle to rise.
  • The coating material enters into gun cavity thru PT1/4” fluid fitting then passes thru the opening of the gun orifice in the needle seat of the gun extension.
  • Air pressure removed, the needle returns back to the needle seat and stops the flow of material.
Ⅲ. FEATURES & BENEFITS / NCAS-gun
  • Dispense in linear bead, spiral bead and spiral spray modes with a single gun and nozzle.
  • Virtually eliminate masking works and reworks thru precise, selective coating application.
  • Apply pattern width from 3.0-12.0(mm) and film build from 0.5-8(mils).
  • Over 85% transfer efficiency(T.E.) results in better material utilization, less waste and cost savings.
  • Dispense wide range of solvent-base and/or solvent-less coatings with viscosity 10 - 3,000(cPs).
