What are Mobile covers?

Mobile covers are designed to hold, support, attach or to design the mobile devices. The term “Cover” is often used to protect certain material.

So, Mobile covers are mostly used to protect smart phones. These covers are made such that, they could easily fit the mobile body. Mobile covers measures are mainly based on display inches (e.g.; 5.1-inch display).

Types: Mobile covers are of different types:

• Bumper
• Skins
• Shells
• Hostlers
• Pouches & Sleeves
• Flip cases
• Wallets
• Screen protection and body films
• Drop & Shock protection
• Leather Case
• IncipioSpeck
• Body glove

Desired Properties for Mobile Cover:

Desired properties for end use application of mobile cover are given below:

Impact Resistance:

Mobile covers should be tough so that it should resist the sudden impact and protect the body of mobile device.

Thus, material of mobile cover should be impact resistant.

Easy to hold:

Mobile cover should be easy to hold and grip. It is easy to give mechanical properties to the material, but what is hard, is to provide a material a good grip and hold so that it should safely use in hands safely.

Speck cover

Durability:

Mobile Cover should be durable.

  Durability is the ability to withstand wear, pressure and damage. It should be reliable.

High Strength:

The strength of material of mobile cover should be high so that it can bear any type of stress without deformation or permanent strain.

Incipio cover

Surface finish of mobile cover should be great. This means that the texture of the surface should be soft.

Less Degradation:

The material of mobile cover should have less degradation. It should not degrade in exposure to UV radiations and other sensitive rays. So that it cannot harm the body of mobile device.

Leather case

Material of mobile cover should be water resistant so that it cannot allow the water to pass through it and harm the body of mobile device. If it does, it will also harm cover. Else, it should be waterproof.

Long-lasting:

Material of mobile cover should be made such that it should last long. It is the important end use property for the mobile cover.

Chemical and fungus Resistant:

Chemicals can also harm the body of mobile phone that’s why it is important to make the material of mobile cover Chemical and fungus resistant.

Pouches and sleeves

• Light weight
• Fire resistant
• Adhesive to dust.

Raw Materials:

There are basically three types of plastics used in making cases. These are hard, soft and hybrid plastics. While hard plastic cases are made up of either polycarbonate, hard polyurethane and polypropylene. Thermoplastic polyurethane or regular polyurethane are used in the manufacturing of soft plastic covers.

Silicon Cover

There are basically three types of leather used to make mobile phone cases. These are aniline leather, semi-aniline leather and pigmented leather. Leather cases are usually folio-styled, are handcrafted. However, handcrafted are very expensive and more prone to wear and tear.

Wooden covers are usually made up of bamboo, teak or elm tree woods. As their raw material source is naturally occurring, that’s why they are usually very expensive.

Silicone is similar to plastic but it is a versatile material made from naturally occurring material found in sand and quartz.

Polyurethane cover

Rubber is also the material by which we make mobile covers. Rubber can come from two sources. Real rubber is made from sap of a rubber tree. Synthetic rubber, which is most commonly used today, is made from petroleum products.

Metals are also commonly used today. For its application, Aluminium is most commonly used to make mobile covers.

Carbon fiber is relatively new invention that is also used in the manufacturing of mobile cases and covers.

Most Commonly used materials:

Mobile covers and cases are mostly made up of following materials:

Polycarbonate Cover

• Silicone
• Plastics
• Polyurethane
• Polycarbonate
• Polypropylene
• Hybrid
• Tuff
• Verge

Polypropylene cover

• Kinetic
• Aluminium metal
• Leather
• Rubber
• Bamboo wood

Carbon fiberDetails of these materials include properties, advantages, disadvantages and reasons to use which are given below:

Totu silicon back cover

Silicone:

• Silicon rubber is an elastic material. Due to this elastic property it is used in a wide range.
• It is a versatile material & naturally occurring material.
• It is considered more softer than plastic covers.
• It is soft, flexible, fire resistant and skin like covers.
• Sensitive to tear especially when in contact with sharp objects.

Attract a lot of dust & lint.

• Good impact resistance thus has good protection.
• It is waterproof.
• Chemical & fungi resistant

Plastics:

• Plastics are easily available material & thus it is used commonly in mobile covers.
• They are tough and lightweight.

TUFF hybrid case

• These are cheaper, dust proof and have strong grip.
• These are very popular due to wide range of different designs.
• Polyurethane rubber is cheap, easily available in both hard and soft form.
• It is easy to hold and has good impact resistance.
• The bad character is that it odors badly.
• While Polycarbonate is tough, light in weight and has great strength.

Verge Covers

It also has good impact resistance and it also resist chipping, cracking & scratches.

The bad thing is that it is slippery and degrades when exposed to UV rays. It also gets dirty easily.

Some additives are used to prevent it from degradation.

Polypropylene is a type of plastic that can easily be injected into molds to form different shapes. For such ease, we use polypropylene.

Hybrid:

These are made from the combination of two or more materials to make a better product.

Tuff:

It is the combination of silicon and polycarbonate. This hybrid case has corner cushions that offer protection against drops and impacts.

Verge:

This hybrid is composed of polycarbonate and silicon. Silicon makes its inner core and outer core boundaries from polycarbonate.

Kinetic Cover

It is a hybrid of polycarbonate and thermoplastic polyurethane. TPU protests its boundaries and PC Protects the mid-section.

Aluminium metal:

• Aluminium is mostly used metal in the manufacturing of mobile covers & cases.
• It is used mostly because it is lightweight metal.
• It is durable, long lasting, smart & fashionable.
• It has great surface finish and lustrous at the same time that’s why it is slippery.

Al metal cover

• It has high strength and good impact resistance.
• It is waterproof & good conductor which sometimes leads the mobile phone to drop the weak signals.
• It is expensive as compared to plastic and silicone.

Leather:

• Leather, of course, is made from the hide of cows and other animals.
• May be synthetic or form from the animal skin.

Leather covers

It is very soft and durable.

Silicon rubber soft cover

• It also conveys style & luxury for desired people.
• Its texture is very soft & grips firmly.
• Its disadvantages are that it is very expensive & not a pocket friendly product.
• It may harm the body of mobile phone when fallen.
• Least variety in designs & colours are available.

Rubber:

Rubber can come from two sources. Real rubber is made from the sap of a rubber tree. Synthetic rubber, which is more common today, is made from the petroleum products.

• Bamboo Wood case
• Carbon fiber covers

Note:

• Bamboo Wood case
• Carbon fiber covers

Note:

• They are soft and squishy feeling.
• They provide good protection.
• Rubber based covers add some extra weight and size to your phone.
• They may also have good hold & grip.

Bamboo & other woods:

Bamboo is beautiful and considered. Green – because it is a renewable resource. As a result, bamboo cases are very trendy. Many people prefer wood cases because they are a natural material than plastic or silicone.

• These cases are a bit of novelty items.
• But they are not widely available on stores.
• Wooden cases are usually made from CNC machine.

Carbon fiber:

• Carbon fiber is a relatively new inventions that takes microscopic strands of carbon and weaves them together to make a very strong, resilient material.
• Such mobile covers are strong and light in weight.
• Thus, they do great job of protection.
• These cases are water proof, non-poisonous and resistant to fire.
• These are durable, unique and have beautiful surface finish.
• Available in lot of colours and designs.
• Disadvantage includes that they are more expensive.
• MOSEVIC is the name of company which made this type of mobile cover. It is a company of jeans.

PELA cover

PELA:

• This mobile case is made with the combination of flax straw and bioplastic elastomers.
• Main advantage is that they are Eco-friendly.
• It is also flexible and have great grip.
• It has the property of high shock absorption.
• It is expensive.

Some Quality Tests:

Military Drop test: measures ruggedness of product.
