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.
More color space, more contrast.
Better ink transfer.
Can use a smoother anilox.
Match offset (halftone) quality.
