Alufoil Aluminum Foil

Aluminum Foil is an aluminum alloy made in thin sheet form. The thickness of Aluminum Foil ranges from 0.2 mm and contains about 92% to 99% Aluminum. Aluminum Foil is available in a variety of sizes and characteristics and is mainly used to package various goods. Aluminum Foil is sometimes also coated with plastic to make it stronger. Aluminum processing was first introduced by Hans Christian Oersted in 1825. Then continued by Friedrich Wöhler for resulting in more effective aluminum processing. But processing aluminum at that time was still very expensive and made the final product price aluminum is much more expensive than gold. In 1908, aluminum was produced with a thickness of 0.05mm with a rolling pack system by Alfred Gautschi. The following years aluminum production became increasingly modern, that is means that aluminum foil can be produced to be thinner and wider accordingly needs. 

The European Aluminum Foil Association provides several facts about aluminum foil. 

-Aluminum foil is a very thin sheet of aluminum (range 0.02 µm to 0.2 mm) 

-Aluminum foil is generally used for packaging and lamination as well has the advantage: 

Absolute material that can protect the contents. 

Provide quality warranty contents by protecting fragrances 

Protects contents from light, oxygen, moisture, and contamination 

-Aluminum foil saves far more resources than that consumed in production throughout the supply and value chain. With facts about aluminum foil which is very efficient as wrapping material, often aluminum foil is almost a raw material packaging coating on each product.

Use Alumunium foil in food 

When making bread, wrap it in Aluminum Foil paper to keep it warm. 

Use the Aluminum Foil paper to melt the sugar, so even desserts will taste more delicious due to the spread evenly. 

When making pies you are usually troubled by the burnt edges. But that won't happen if you base the Aluminum Foil on the baking sheet. 

When baking a cake, it is not necessary to spend a lot of money buying the molds. Just use the Aluminum Foil paper by forming it like a cone and cutting a little of the sharp part.

Cold Rolled Sheet Steel Metalworking

Cold Rolled Sheet or white iron plate is the process of making iron plate by grinding. The rolling process is carried out under the recrystallization temperature. White Iron Plate is also known, with the improvement of Black Iron Plate. Cold Rolled Sheet is a type of steel product that is produced by cold rolling, and has characteristics very different from that of 'black steel' or hot rolled steel. CRS has better surface quality and is more precise, and has good mechanical properties and excellent formability. Widely used in the ordering process because of its better formability, weldability and roughness qualities. This type of steel is also used for applications in the galvanization industry, the enamel industry, and is used as a raw material for the tin-coated food can industry. For annealed sheets, the thickness ranges from 0.20 - 3.0 mm, and the thickness is reduced to 2.0 mm. Hot Rolled Coil (HRC) or Plat (HRP) is a type of steel product that is produced by a hot rolling process. Ordinary users usually refer to this product as 'black steel' in contrast to Cold Rolled Sheet which is traditionally referred to as 'white steel'. Krakatau Steel produces ordinary carbon as well as various micro-alloy steels that can be used for general or commercial quality to special qualities such as: general steel structures, automotive frames, piles, heavy equipment components, general fabrication, general pipes & tubes, pipes & tubes for linepipes and casings, gas cylinders, weathering corrosion resistance, pressure vessels, boilers and shipbuilding. Plate sizes are 0.18 to 25 mm for thickness and widths of 600 - 2060 mm, and can be supplied as coils, plates and conditions can also be rolled or pickled and oiled (HRC-PO). Krakatau Steel has a thermomechanical heat control process and a desulphurisation process using a ladle furnace, which is essential for producing high quality hot rolled steel for special applications. Krakatau Steel manufactures coils and hot plates that are devoted to the automotive industry and require better capability, traction and better surface quality. They are used for automotive frames, wheel discs and rims, as rear, fuel tanks, oil filters, etc. Also included in this group are general drawing applications that can be used outside the automotive industry but have similar requirements, notably good weldability and drawability.

The advantages and disadvantages of White Iron Plate are:

Light and Strong. The iron body has a heavy weight, but the white iron plate has a light weight but does not reduce its strength.

Easy to customize. White iron plate is easy to form such as: bending, cutting, or welding.

The price is more expensive.

It takes longer.

Spring Machine Element Control Movement

The spring is a machine element that functions to control movement by holding, dampening vibrations, smoothing collisions and other motion control models. Simply it can be said that the spring is an energy storage medium for motion control. Spring is an elastic object that is used to store mechanical energy. The springs are usually made of steel.

Springs can also be found in car suspension systems.

In cars, springs have the function of absorbing shocks from the road and wheel vibration so they are not transmitted directly to the vehicle body.

In addition, springs are also useful for increasing tire traction on the road surface.

When a conventional spring, without the stiffness variability feature, is compressed or pulled from its free position, will use the opposite force in proportion to the change in length.

The rate of spring or the spring constant is the change in force that it exerts, divided by the change in spring deflection. That is, it is a force gradient versus a deflection curve.

The degree of stretch or the degree of compression of the spring is expressed in units of force divided by the distance, for example N / m or lbf / in. A torsion spring is a spring that acts on rotation, when rotated around its axis at a certain angle, it will produce a torque proportional to the angle.

The rate of spring torsion is in units of torque divided by the angle, such as Nm / rad or Nm / degree.

Printing Ink Purpose and Function

Printing Ink, Purpose and Function.
Submit information.
Provides protection.
Provide color and decoration to attract consumer attention.
Differentiate with other products / brands.
Color aims to provide tricks and play emotional / consumer feelings in increasing attractiveness to a product
The first impression of a product depends largely on the appearance of the packaging - the printing decoration comes from the ink.
Flexo printing A direct printing method that uses relief image plates made of a rubber or photo-polymer type material.
Anilox roll as a measuring tool for ANILOX ink volume so that it can be evenly distributed.
HD Flexo is a new technology in digital plate production - resulting in quality.
flexo printing is one level better than offset.
HD Flexo is a combination of high resolution 4,000 dpi (conventional ~ 2540 dpi).
with high anilox linecount, can produce.
Higher image definition.
