Processing Guidelines

(1) Thermoforming
1.1 Equipment is required like a forming, trimming and molding equipment.

(2)Storage
(2.1) INS films should be stored under normal operating conditions. Boxes containing rolls of INS films should be stored in a horizontal position. This material should not be stored outdoors, in places of high humidity or where extreme temperatures can be attained. Temperatures below the freezing point and over 35°C should be avoided.
(2.2)If the roll of film is to be stored again, it must be kept wrapped in the moisture vapor barrier with desiccants inside. The wrap needs to be sealed at the seam with a PET tape, and then sealed at the core end with a core plug or something similar.
(2.3)Recommended storage is 25°C or cooler at the lowest humidity level possible. Re-dry after 5-6 months.
(2.4)It is recommended to pre-dry sheets 2 days at 70℃, full unwrapped rolls min. 48~72 hours at 60℃ in a circulation oven.

(3)Forming
(3.1)Slow heating of the film, preferably heating the film back side targeting a sheet temperature of 120℃~145℃measured by temperature labels.it depended on the different part and film type.
(3.2)Operation in clean room is preferred.

(4)Trimming
(4.1)It is recommended to use laser cutting, or die cutting, generally die cutting.When trimmed, ensure that the material is not damaged, no dust, dirt pollution,trimming scraps on the surface.
(4.2)To avoid surface damage we recommend the following operations:
(4.2.1)Do not pile on top of each other without soft tissue or cloth between each part.
(4.2.2)Have all personnel wear soft or latex gloves.
(4.2.3)To avoid dust pick-up or contamination we recommend the use of anti-static devices specifically designed for clean room atmospheres.

(5)Insert molding
(5.1)No special equipment is necessary when processing INS film. Existing molding equipment can be used; however, moulds should be made or modified to accept the film in the cavity. Further recommendations:
(5.2)The temperature of the diaphragm inserted into the mold cavity should be 30-50°C.
(5.3)Film friendly gating to prevent wash out of color and or graphics.
(5.4)Resin temperature as recommended by the resin supplier.
