Slight Grain Finish Smart Card Material Used For Plastic Card Lamination

Slight Grain Finish Card Laminated Steel Plates Smart Card Material For Plastic Laminator Use

Production Specification

1. Slight Grain Finish Card Laminated Steel Plates Introduction

Slight Grain Finish Card Laminated Steel Plates are used for laminating plastic card sheets in the card laminator. It can ensure perfect plastic card surface finish after lamination . Our plates are being widely used by many card factories in both China and foreign countries worldwide.

2. Slight Grain Finish Card Laminated Steel Plates Specification

Key Features:

1. The two sides are covered with protection foils (blue thin films) to ensure good protection on both surfaces . There is no glue left after the foil is removed before the plate is used at the first time .

2. Two sides are made slight grain in the same quality .

3. There are no scratches , dents, stripes shadows and dust on plate surfaces .

4. The edges are smooth and deburred with the round curved corners .

5. After lamination , the plates are not sticking to the laminated plastic sheets .

The lamination steel plates apply the #430 cold rolled stainless steel plates with the thickness of 0.6 or 0.8 mm. The general production processes are summarized as below:

Step1 Raw Material Selection : Hot rolled strip is used as a raw material for cold rolled stripe.

Step 2 Scouring/Pickling : Use a pickling unit to remove iron oxide from the surface of hot rolled strip

Step 3 Cold rolling : After multiple passes of cold rolling, the finished steel strips shall meet the size, shape and surface quality requirements.

Step 4 Heat treatment : Annealing the cold rolled strip to achieve the desired properties.

Step 5 Finishing: the final product is obtained by leveling, shearing and packaging the annealed strip steel coil

Step 6 Flattening and film application : Release #430 stainless steel sheet coil, then flatten it on the flattening line, cut it into standard size

stainless steel plate, and attach protective film on both sides of the steel plate to prevent scratches of the steel plate.

Step 7 Tailor cutting : According to the size requirements of customers, the large steel plate is precisely cut by using the shearing machine.

Step 8 Visual Inspection : Make a comprehensive inspection of each finished steel plate, check the dimension, thickness and surface quality, and eliminate unqualified products. If it is matte finish steel plate, according to customer's requirements, sandblasting machine is used on both sides of the steel plate to achieve matte finish effect, and then apply protection films on both sides before quality inspection.

Step 9 Packaging and labeling : Packaging the qualified products by using fumigation-free wooden cases, and inside the wooden cases, the soft materials are applied to maximize the protection of steel plates during the process of handling and transportation. The proper label or logo is applied on the case surface before shipment.
