High quality slitting from narrow to wide in a class 10,000 clean room

Film Processing
Film Processing
We are engaged in slitting electronic and optical films. We conduct slitting and laminating processes for functional films in a clean room rated as Class 10000.
It has a small size, light weight and high performance electronic devices, portable phones, displays, functional films used in semiconductor fields, optical film, special double-sided tape, pet separator, laminated film, acrylic foam, etc. In addition to the precision slit processing of a wide range of materials in the clean room of the class 10000 level, lamination processing, alcohol cleaning, sheet cutting, sewing machine, etc. are done.
We have also developed products to meet our needs, and we have developed precision slit processing technology and product development in China. Its precision processing and product development support product development in terms of resource saving and energy saving, and challenges the cutting edge of the times increasingly.

Capacity to process vairous materials

We are capable of processing various materials such as PET film, PE/PP films, electrical insulation films, functional films, adhesive tape, buffer material, optical materials, and metal films. Our equipment is able to process the materials with the maximum width of 1600mm.?

Machining Thickness  Thickness 0.006mm~1mm
Materials Weight  Max 500kg
Material Max. Dia  φ800mm
Machining accuracy with±0.1mm width
We slit the materials based on the width specified by clients with the machining accuracy of ±0.1mm. The minimum of slitting width is 0.8mm and clients can request to widen it by 0.1mm. Slitting width below 0.8mm is also available upon requests.
Compatible with original ABS core with step
Countermeasures against unevenness in the core of high-value-added films and measures for clean rooms Dramatic reduction of film level difference defect due to level difference of winding core.
Contributes to cost reduction and CO2 reduction.
Please consult us for details.
Burn-in Test
We provide burn-in test.
Provided to burn-in test within Maximum temperature 80℃
Corona Treatment
We are planning to install Corona treatment facility with 1,600mm width.
Sheet cutting processing
It’s available to cut at below specifications. Width : 1,450mm, Length : 60-9999mm, Tolerance : within +/-1.0mm
We provide longitudinal pinhole processing. The distance and shape is according to client’s request.
Laminate processing
We offer laminate processing such as laminating a surface protection film on an optical film while slitting and laminating a release film on a tape. The lamination for two or three kinds of materials is available upon clients' requests.
Diffuser sheet+PET carrier tape
Reflection film+Surface protection film
Special optical film+double-sided(front and back sides)protective film
Cleaning processing
For industries with a high degree of clean requirements, we recommend ISR’s alcohol cleaning process. Our cleaning line offers full cleaning service for the front and back sides of film. Other kinds of cleaning apart from alcohol are also available upon request.
Ultra-precision slitting process
Minimum wide between 0.8mm to 10.0mm of micro precise slit processing can be provided.
