The production process of tablet case  (taking iPad case as an example)

iPad case production


With the increasing development of mobile communication, iPads are becoming increasingly popular globally, especially among young people. When people have their own iPads, the first thing they need to do is to prepare some accessories. Due to the fact that the external structure of the iPad is made of metal materials and covered with a very smooth layer of baking paint, it is easy for people to break the iPad due to slipping hands when using it. Therefore, after having an iPad, choosing a ipad case is essential.

We have seen various styles and materials of iPad cases in digital product stores and online. However, what materials are used for these iPad cases and how are they made? I believe many iPad owners must be particularly curious about the production process of iPad cases, right?

To understand the production process of iPad cases, we first need to know the basic components of iPad cases. Almost all iPad cases on the market are composed of these parts: back shell, fabric, lining, magnet, PVC board (or cardboard), and adhesive with sufficient viscosity (or hot melt adhesive).

I will tell you about the production process of our factory's classic TPU+PU leather material three fold iPad case.

1. Preliminary preparations for producing iPad cases

Before preparing the iPad cases for production, all raw materials need to be prepared, such as the back shell (produced by a specialized back shell mold factory), PU leather fabric (produced by a leather factory), magnets (processed and produced by a specialized magnet factory), and PVC sheets (cut and formed by a specialized PVC sheet material factory). Before the raw materials are put into storage, quality inspection is required to confirm the size, color, hole position, appearance, etc. of the back shell for inspection; Inspect the density, color, pattern, toughness, etc. of PU leather and super fibers; Sample and confirm the magnetic force and size of the magnet... All raw materials can only be stored after passing the inspection.

2. Production of surface cover and back shell molds

Different sizes of iPad cases require molds with different appearances and sizes, such as iPad Air4, Air5 cases, and iPad 9th, 8th, and 7th generation cases. The dimensions, button positions, edges, and corners of the same brand and size may vary. For example, the size of iPad 10th and Air4 Air5 is 10.9 inches, but due to the different button positions and machine thicknesses of the speaker, volume, and other buttons on these two iPads, Different molds also need to be manufactured. Even for the same model of iPad protective case cover, due to different materials and appearances used, it is necessary to make different iPad case product molds.

3. Division of labor production for each component

Next, professional cutting workers will use a cutting machine to cut the fabric and lining according to the set size and appearance; Cleaning workers will be responsible for repairing and cleaning the TPU back shell; The driver transports the PVC board (or cardboard) and magnets to a specialized processing factory for drilling, and embeds the magnets into the PVC board according to the position of the holes. After embedding all magnets into the positions of the holes on the PVC board (cardboard), a layer of adhesive film is used to fix the magnets on the front and back of the PVC board (cardboard).

4. Production of finished iPad cases

After producing all the components required for the iPad protective cover, the next step is to assemble these components into a whole.

The first step is to place the cut super fiber lining, PVC board (or cardboard) with magnets installed, the cut fabric, and solid glue on the pre made cover mold in a smooth and orderly manner. Then, start the hot pressing molding machine and heat it to around 120 ° C. The high temperature of 120 ° C will continue to heat for 5 seconds, and the solid glue will quickly convert into liquid due to high temperature heating, firmly bonding each component into a whole. After hot pressing, the cutting machine will perfectly cut around the face cover, and a complete iPad case is produced;

The second step is to conduct quality checks on all produced iPad cases and eliminate products that do not meet product quality requirements, such as covers with dirt, roughness, uneven cutting, or fabric deformation caused by overheating. These are all products that do not meet product quality requirements.

The third step is to place the iPad back shell on a pre made back shell mold, and then cover the iPad back shell with solid glue and iPad cover flat. Start the hot pressing molding machine, heat it to about 120 ° C, and continue for 5 seconds. In this way, a complete TPU three fold iPad case with auto sleep function is produced.

Step 4: Next, the production line workers will conduct product quality testing, surface cleaning, ventilation and cooling of the produced iPad case, and then proceed with logo printing. After printing the logo, the quality of the logo will be tested.

Step 5: After the production department completes all inspections and before the iPad cases are labeled and packaged, our factory's quality department will conduct a systematic quality inspection and cleaning of the iPad cases using the iPad machine, such as appearance, overall effect, cleanliness, button position, auto sleep and magnetic suction functions. After all the above checks are passed, the iPad cases can be labeled, packaged, and ready for shipment.
