How are mechanical pencils produced?

mechanical pencils are produced through an automated process in assembly factories. Most pencils are made of plastic and have a hollow barrel, writing a tip, rubber and a built -in lead control method. The rubber is usually added to the upper end of the pencil and is removed to access the lead barrel. There are two methods of manufacturing mechanical pencils: manual assembly of individual parts or use of a plastic mold created.

Before the production of mechanical pencils, there is a design control process. The target consumer must be identified and the key features for reviewing the proposed product. It is necessary to make a decision on the color, texture and aesthetics of the outer body. Schematic drawings are completed at the end of this process. These drawings provide accurate measurements for different pencil components, from the size of the barrel to the mechanism used to control the lead pencil.

In the manual compilation process, these specification data are provided to different parts of manufacturing companies to provide the PendantLadors and timelines to the assembly company. Design specifications include details of different lead sizes that must be able to accommodate and any other features. The components are produced on the basis of these requirements.

The barrel of mechanical pencils must have enough space to detain between five and ten individual pencils. The barrel can be made of plastic, metal or a combination of rubber and plastic. The mold is made of desired shape and the machine is used to produce barrels.

The metal company complements the formation of the tip of the pencil and any other metal parts. The tip is produced with screw grooves, because it is the safest way to connect the tip to the barrel barrel. The mechanism of leading lead is usually metal and is created by a firm. After the order is completed, these pieces are handed over to the assembly plant.

Assembler puts the progressing mechanism into the barrel and checksto ensure that it works properly. The pencil mainly adds to the transport belt that passes through the machine that puts the pencil leads into the barrel. The tip is screwed into the barrel and the rubber is inserted into the top of the barrel. The pencil is then placed in the packaging material and ready for sending.

For a fully formed disposable model, forms for the barrel holder, tips and rubber creates as one piece. The mechanism moves the mechanical pencil forward with lead and inserted into the barrel. Eraser is added at the top of the pencil as the last step before placement in the wrapping material and sent.
