How to straighten a silicone case. Different ways to stretch leather and silicone phone case. Reshaping by thermal means

The desire to beautifully decorate your phone arises in every visitor to the site of the online store https://itsellopt.com.ua/ at the sight of attractive covers and bumpers. But not all of them can give the means of communication proper protection in the event of a blow or fall. And if there is a shock-absorbing bumper for the phone in the assortment, then it will either not be suitable for your model, or its cost will be astronomical. There is only one way out - to spend a little time, imagination, effort and make a beautiful case from improvised materials.

Everyone wants to decorate their phone

Colorful bumper can be made from mold making silicone without touching brushes, glue.

To prepare the material you will need:

  • Construction silicone;
  • Potato starch as a thickening agent and for whitening;
  • Color or acrylic paint.

In the process of kneading, it is better to use silicone gloves. So the hands will feel the material, and you won’t have to wash them for a long time.

Manufacturing technology:

  1. After squeezing out the silicone, you need to add two tablespoons of potato starch to it.
  2. The process of kneading the silicone "dough" is similar to the preparatory stage before sculpting from plasticine. It must be kneaded until the mass becomes homogeneous.
  3. If you divide the resulting mass into several almost equal pieces, and add color to each of them, you will get multi-colored balls. They need to be flattened, folded so that each previous one peeks out a few millimeters from under the previous cake.
  4. Using a rolling pin, the workpiece must be rolled out so that it is enough for the back wall of the gadget, its edges and a small bend on the front side.
  5. The phone is wrapped in the resulting multi-colored or plain silicone sheet.
  6. It needs to be pressed a little into the "dough" in order to outline the holes for the camera, the speaker grill, located on the back side.
  7. Connectors, control buttons from the side elements of the phone must be outlined by swiping your thumb around the entire perimeter of the phone.
  8. The silicone needs to dry. Its readiness time depends on the thickness of the rolled layer and the data provided by the manufacturer.
  9. It is better to remove excess silicone immediately with a stack or a plastic knife. Without excess material, it is easier to form corners.

Advice! The hardening of the silicone mass can take up to 12 hours. Move the SIM card to another phone or make call forwarding. Otherwise, a smooth surface of the cover will not work.

How to make a transparent phone case

The easiest way to put your phone in a transparent case that only protects from getting wet and dusty is to use a piece of shrink wrap. You can find the starting material at any grocery store. It comes in glass jars with canned food.

You can find the source material at any grocery store.

By cutting a rectangle out of the film so that it is 1.5-2 cm larger than the phone on each side. When bending the film on the front side of the phone, it must be heated with a lighter flame. Only the flame should not touch it. A uniformly planted film will become the skin of the gadget. It can only be removed with scissors. But that will be much later. In the meantime, a manicure set is required in order to cut holes for the camera, side buttons, charger and headphones.

Transparent silicone case

To make a transparent silicone case, you need the appropriate quality material. Silicone sealant for glass bonding is best suited for this purpose. Its setting time is 30 minutes.

For work you will need:

  • Box. The one in which the phone was sold will do.
  • Soft plasticine or dough for modeling.
  • Polyethylene film to protect the phone from contact with materials - plasticine and uncured sealant.

Step-by-step instruction:

  1. The box is filled by a third with plasticine or dough.
  2. The phone is placed in a thin plastic bag.
  3. It must be placed in the middle of the plasticine cushion and pressed evenly to get a shape 2-3 mm deeper than the thickness of the phone itself.
  4. The resulting form must be smeared with an even layer of sealant.
  5. Re-insert the phone into the recess made by it.
  6. Silicone extruded onto the surface can be slightly leveled, giving it the shape of a future cover.
  7. After the material dries, the phone together with the bumper is taken out of the mold. Cleaned from plasticine and polyethylene.

Advice! If the protective layer of the cover is planned to be thicker than 3 mm, then the recess in the plasticine mold must be made deeper.

How to decorate a silicone case

Decoration of the silicone case can be done in the process of its manufacture.

  1. You can insert small rhinestones in the form of your own initials, contours of animal faces and other simple ornaments into a thick transparent silicone layer.
  2. Sequins are added to silicone in the process of smearing the mold with it or preparing the “dough” before rolling. In the first case, shiny crumbs can be poured through a strainer, which is necessary for even distribution. In the second, it is better to mix them with potato starch.
  3. Glue-based rhinestones will allow you to make an original decoration on the back wall of the bumper.
  4. The most original and unique silicone covers are obtained by decorating with bitmaps made with acrylic paints. Material in small tubes with dispenser spouts can be purchased at needlework stores. You can draw and decorate any pattern for the cover yourself.

The easiest way to decorate is to find a beautiful picture in the right format and insert it between the phone and the case. It makes for a great decor.

How to make a balloon phone case

The technique of creating such a bumper is like vacuum packing a phone in latex.

  1. The balloon inflates to medium size.
  2. It must be laid on a flat surface, holding the neck with two fingers.
  3. Place a phone in the middle.
  4. The gadget must be slightly pressed down, and the air from the ball must be bled.
  5. A couple of minutes of work, and the phone is dressed in a new bright shirt.
  6. It remains only to cut holes for the camera and connectors, and thin material will not interfere with the operation of the buttons anyway.

Paper smartphone case

A book cover made of vinyl wallpaper is made according to the principle of a box.

For this you need to take:

  • ruler;
  • Pencil;
  • Scissors;
  • Glue.

The cover can also be made using origami

Cover making:

  1. On a sheet of paper, stepping back from the edge of 1 cm with an increase in the thickness of the side wall, the contour of the phone is outlined.
  2. Departing from Figure No. 1, a gap equal to the thickness of the device + 1 mm, the phone is circled a second time.
  3. Above and below the wall thickness + 1 cm is also added.
  4. Cut out, using nail scissors or a blade, holes for the charger, headphones, camera lens, screen.

The same bumper, made of corrugated cardboard, will give excellent protection to the phone in case of bumps and falls. The only thing is that it is more difficult to decorate it. It can be painted, applied to it with a dense bitmap with acrylic paints. But this will not protect the paper from getting wet in the rain.

You can independently increase the moisture resistance of paper or cardboard using lamination. In order for a homemade cover to be both beautiful and moisture resistant, it must first be cut, painted, laminated, and only then assembled.

Is it possible to shrink the rubber cover

During operation, the rubber covers stretch. They can be returned to their original size. To do this, they must be immersed in boiling water. They will become more plastic, and when cooled, they should return to their original size.

Some bumpers made of rubber with a high proportion of plastic are not as flexible as rubber. But they can also be made smaller at home. If immersing the cover in boiling water does not lead to the expected result, you can try to boil it for 5 minutes - the principle of preparing a polyethylene suction cover. He works. Just do not need to pull a wet bumper on the phone, the moisture must be removed from it.

Not all cases fit the phone equally well. Many users are faced with the problem of discrepancy between the size of the protective accessory and the actual dimensions of their device. For someone, the gadget falls out of the case, for someone, on the contrary, the case turns out to be much smaller than the device. Today RosCase will tell you how to deal with such problems, how to shrink or enlarge your silicone phone case.

First of all, we want to protect you from such situations. Our main advice - do not buy the cheapest product from a dubious seller. A low price may mean that the materials used in the manufacture of goods are not of the highest quality. Therefore, full compliance with the high requirements of the user can be left in rosy dreams. If the plastic case does not fit snugly, then you can always try to return it to the seller.

It is much safer to choose accessories from well-known brands, carefully study the characteristics of the cover before paying for the purchase. Trust our many years of experience - branded accessories are made with much more care. The materials used are proven, and the dimensions are precisely adjusted to the dimensions and functional features of a particular device. On our website, there are covers from such well-known manufacturers as Rock, Nillkin, Tetded, Nuoku, Mercury, etc. And all their sizes are ideal for the indicated device models.

If you have already become the owner of a would-be case, first of all you can try to return it back to the store, based on its inconsistency with the specified model. Only in the event that you failed to do this, you can proceed to independent procedures and subject the case to various tests. After all, there is nothing to lose.

What kind of aids for resizing are advised on the Internet: a hair dryer, alcohol, a freezer, boiling water, acetone, even a microwave oven. We tested, in our opinion, the most adequate way - and we managed to shrink our experimental sample by a few millimeters.

So, for our experiment, we needed the case itself, a stove, a saucepan, and water. We boiled water - and lowered the cover into it for 7 minutes. While the cover was cooking, hold it with a spoon so that it does not float up. After undergoing a rejuvenating procedure, the accessory went to cool down. When its temperature dropped to normal, we tried it on our smartphone - the cover no longer fell off it and fit snugly.


To clarify, our case was made of opaque silicone. On transparent covers, this method has a very ambiguous effect, turning a transparent material into a matte one. Well, if the color of the case is unimportant to you, but its functionality is important, this is unlikely to stop you. But, in turn, we warned you. Also, after experimenting with several more overlays, we came to the conclusion that not all of them reacted with compression to bathing in boiling water. Some have remained larger than necessary in size. From this we concluded that this method is not suitable for every case, but you can still change the size of the silicone case. Unfortunately, you can find out if this method is effective for your case only by conducting a similar experiment yourself.

How to solve the problem of increasing the cover

As for tips on how to stretch a leatherette phone case, there are slightly different approaches. We all know that skin tends to stretch. Good leatherette also provides for similar opportunities. By analogy with natural material, you can try to stretch the case by putting a model of your device into it, for example, made of wood. First, the base must be split in half, installing a spacer in the center, which will increase the capacity of the cover.

Experts advise placing this entire structure in warm water and leaving it for a while. After the spacer is removed and the case dries, it should take on a new desired shape that will allow it to be easily installed on the gadget.

Do not forget that before trying this method, you should, again, contact the seller and state to him your claims regarding the defects of the ordered goods.

Summarizing all of the above, we want to say that it is still possible to return the shape to a deformed phone case. But not everyone. Therefore, before buying protection for your device, make sure that it is perfectly compatible with your device by asking the seller for information. Then, if the slightest discrepancy arises, you will have a reason to return the case, and not look for ways to change its size. Good covers for you!

Even a silicone case purchased for a specific phone model may not be the right size. If it was sent through an online store or purchased without "trying on", then it may be difficult to return the goods. In this case, it becomes necessary to take action on your own. In the current article, we will consider how to stretch silicone or, conversely, shrink it using improvised means.

How to stretch silicone phone case

Silicone is a fairly strong material, which at the same time is very elastic. A significant disadvantage of such covers is associated with the latter property - they stretch over time. Well, if you want to speed up the process and increase the size of the lining immediately, there are several effective ways:


The presented methods will help to cope with the problem of a small case, if its size needs to be increased by 1-3 mm.

How to shrink a silicone case

As already mentioned, silicone has a significant drawback - it stretches after some time of operation. For this reason, the question arises of what to do if the silicone case is stretched. You can try to reduce it using the method below. The presented method has been tested by many people and is guaranteed to help you cope with the task.

Before proceeding with specific actions, you should know that a decrease in size will occur by 1-2 mm. If the cover is very loose, then it is better to buy a new one and not waste your time. In the event of a slight stretch, the following steps must be taken:

  • Choose a pan that will allow you to completely place the overlay in there without touching the edges. Pour water into it and put it on the stove to heat up.
  • Bring the water to a boil and put the accessory in it.
  • Boil the overlay for about 5-7 minutes, while holding it with a fork so that the water completely covers the material.
  • Remove from saucepan and leave to cool completely.
  • Wipe dry and try on the phone - the cover has decreased and fits snugly to the body.

Before performing the procedure, it is important to pay attention to the material of the lining. The polymer alloy, in case of its transparency, will become cloudy, and real silicone will not change its properties. However, for opaque accessories it does not matter. Some users note that they were able to partially restore transparency by placing the case on the battery for a while.

Some buy a case to decorate the phone, others - to protect the case from scratches and damage. And sometimes a situation arises when you like an accessory for a mobile phone, but the size does not fit. How to stretch the cover and not damage it? To solve this problem, you need to take into account its shape and the material from which it is made. Read more about it.

Stretching a leather case is not difficult

How to stretch a leather case

A leather case that does not fit over the phone or is too tight, causing the buttons to actuate, should be slightly larger. Leather stretches well when wet with water, and retains its shape when dry, so use the simple method.

  • Try to pick up or cut a piece of wood that matches the size of the mobile.
  • Split the resulting workpiece in half along the flat side. Insert a thin plastic plate into the slot.
  • Soak the cover well in warm water and pull it over a wooden mockup.
  • Leave it to air dry, without heat, otherwise the skin will dry out and crack.
  • After about a day, when the cover dries, pull out the plate, and then the wooden block.

The accessory will stretch to the desired size. If you use a mixture of alcohol and glycerin instead of water, the drying time will decrease, the procedure will be more gentle on the skin, and the surface will retain shine.

How to stretch a silicone case

Silicone is a fairly strong and flexible material. There are a lot of covers from it, so you can always choose the right option. If desired, an accessory is bought - a bumper, which is easier to put on and there is no need to select the location of the connectors.

However, there are times when it is necessary silicone case stretch. You can do it like this.

  • Given the property of silicone to stretch over time, you can wrinkle it with your hands and pull it to the sides. If the size does not fit quite a bit, you will soon be able to wear it.
  • After heating, the silicone becomes more plastic, and the case is easier to pull on the phone. You can use a hair dryer here.
  • With a large difference in size, stretching on a wooden layout is suitable. The cover must be heated in hot water, pulled over the prepared bar, heated for an hour in water and cooled in air. The disadvantage of this method is that the silicone can stretch too much and hang out on the phone.
