At the Slat factory pencil stock is cut into Pencil Blocks a bit longer than the normal length of a pencil. It also ensures that the final products have the same length.

The initial raw material for High impact ABS plastic is hydrocarbon products obtained from oil.
Pencil manufacturing process. Large rocks inside the drum crush the graphite and clay into a fine powder. In 1925 Count Alexander von Faber-Castell begins building a modern production complex. Pencil Blocks are cut into Pencil Slats using specially designed circular saws.
The building with its enormous U-shaped design is still used for pencil production to this day. Find out how Staedtler make their pencils in this behind the scenes look at the production process. Also erasers are attached to the pencil using a metal case.
The wood is softened and cut into slats called pencil stock or pencil squares Step Two. The Manufacturing Process Initially at the factory wooden blocks are cut into what is known as pencil blocks according to the length of the pencils. Similar permanent casings may be constructed of other materials such as plastic or paper.
The small amount of extra length is called trim allowance that bears importance later on in the process. Mechanical pencils have more elaborate casings which are not permanently bonded to the core. The eraser is usually added to the top end of the pencil and is.
Mechanical pencils are made through an automated process in assembly factories. You would also like to know How To Influence People Dos And Donts Of Body Language. They leave an extra space called the trim tolerance which will be explained later.
The grooves in the slat are filled with a special elastic glue. For the manufacture of lead you will need to mix the high-grade graphite powder with ball clay in the required proportion. Visit Website httpsbitly2CL8TdKMore Video- httpsbitly3iiirgmPlease Dont Forget Like And Share.
The process is the final step in pencil manufacturing. Crude oil is extracted from the earths crust and pumped to factories where it is refined. Producing 23 billion pencils a year and being in the business for over 257 years Faber-Castell has a sound know-how of how quality pencils are made.
To use the pencil the casing must be carved or peeled off to expose the working end of the core as a sharp point. A wax and stain are applied and the slats are passed under a cutting wheel. This process removes the excess varnish that has accumulated on the end of the pencils.
This makes manufacturing processes more efficient and production can be increased. Most pencils are made of plastic and have a hollow barrel writing tip eraser and a built-in lead controlling method. The Step by Step Process Step One.
Then charge it into a ball mill with sufficient quantity of water for wet grinding. Then water is added and the mixture is blended in the drum for up to three days 6. Mechanical pencil manufacturers commonly use the high impact Acrylonitrile Butadiene Styrene ABS plastic for the plastic components of the pencil.
Wooden Pencil Manufacturing Process. Step 1 STEP 1 Chunks of graphite a soft dark mineral and clay are placed inside a huge rotating drum.
