Manufacture

Heating Film gives customers a better value.
The process of manufacture creates the value of quality.

    01 Design the pattern for heating Film
  • ㆍDesign or use the product design requested by the customer ,and We manufacture products according to customer's request with power consumption data etc.
02 Raw Material Purit & Composition Design
Mixing design refers to the mixing ratio of raw materials used in the heating film, and the process of designing power consumption by varying the ratio according to the use and solvent
  • ㆍ Setting hardening condition of Paste: Heat analysis (DSC), test for dissolving hardened material and etc.
  • ㆍ Measure of Viscosity of Paste: Brookfield HBT-DV II, SC4-14@25°C ± 0.5,10rpm
  • ㆍ Volume Resistence : R(Ω) x T(μm) x H (mm)/L(mm)
  • ㆍ Hardness measurement: Pencil hardness tester
  • ㆍ Measurement for Filler contents: Heat analysis (TGA), IGR
    03 Doping Process
  • ㆍ After conducting pretreatment, spread the paste of carbon and silver as the main material on existing design of circuit pattern.
  • ㆍ Fidelity of film pretreatment is the process that affects the viscosity of product and can technically support the weak parts due to humidity
    04 Heat treatment process
  • ㆍ In order to maintain uniform resistance of the heating part, a high-temperature heat treatment process for complete drying is essential
  • ㆍ Process that directly affects product safety due to chemical properties of fully dried diluent
  • ㆍ Little change in low value due to the double heat treatment process
    05 Insulation Laminating Coating
  • ㆍ Conduct the insulation coating using EVA
  • ㆍ Process that has a decisive effect on product insulation and moisture prevention performance
    06 Quality inspection
  • ㆍ BT (Bare Test: electric capacity test) After manufacturing the film, the process which tests the basic electric performances by multi-tester such as electric defects of products, In other words, Open & Short (Short of circuit), insulation interval deviation and etc.
    Test fixture (JIG) should be prepared and tester types are dedicated type and universal type
  • ㆍ Final Inspection After the electrical performance test is completed, other defects on the surface of the film, that is, coating of copper foil, surface condition of processed copper foil, floor smoothness of laminex, shape and material, materials used, composition of Patten, etc. Focusing on conformity to the customer's purchase specifications, film heater manufacturing technology, management technology, or errors include temperature measurement, other measuring instruments (Vernier Calipers, Dial Gauge, Pin Gauge, Angle Block Gauge), and cosmetic defects. Check by magnifying glass inspection and visual inspection.
