Mechanical pencils are made from a variety of materials, including plastic, metal, rubber, and graphite. The body of a mechanical pencil is typically made from high-impact ABS plastic, which is known for its durability and toughness. This type of plastic is considered the best in the collection of styrene plastics. It is hard, durable, and has excellent chemical resistance. Some mechanical pencils also have a metallic body, which is tougher but may be heavier. The plastic body of a mechanical pencil is designed to be lightweight and comfortable for long-term use.

What You'll Learn
Mechanical pencils are made from plastic polymer materials
The plastic body of a mechanical pencil is typically made from high-impact ABS (Acrylonitrile Butadiene Styrene) plastic. ABS plastic is known for its superior characteristics, including hardness, toughness, and durability. It offers better chemical resistance and dimensional stability compared to other types of plastic. This makes ABS plastic an ideal choice for mechanical pencil bodies, as it can withstand the wear and tear of everyday use.
The use of plastic polymers in mechanical pencils also allows for more design flexibility. Plastic mechanical pencils come in a variety of appearances and shapes, such as triangle and ball shapes. These ergonomic designs help improve comfort and reduce fatigue during use. The lightweight and durable nature of plastic also enables manufacturers to create innovative and aesthetically pleasing designs that appeal to a wide range of users.
In addition to the body, other components of mechanical pencils are also made from plastic. For example, the cone cap, which protects the lead and guides it through the outlet, is typically manufactured from high-quality impact plastic and coated with silver chrome. The internal lead tube, which holds the refill leads, can also be made of plastic or metal. Clear plastic tubes are sometimes used, providing a visual indication of the lead level.
While plastic mechanical pencils offer many advantages, it is worth noting that they vary in price and quality. Cheaper plastic-barrelled pencils may not have the same aesthetic appeal as more expensive options, but they are still perfectly functional. For those seeking a tougher build, mechanical pencils with metal bodies are also available.

Plastic mechanical pencils are available in different lead sizes
Mechanical pencils are available in a wide range of lead sizes, catering to different purposes and preferences. The Deli plastic mechanical pencil, for instance, offers two lead size options: 0.05 mm and 0.07 mm. These ultra-fine leads are ideal for writing within confined spaces, such as when fitting complex equations into small areas.
For those seeking a slightly thicker line, lead sizes of 0.2 mm, 0.3 mm, and 0.4 mm are available, with 0.3 mm being the thinnest commonly available lead size. These fine leads are perfect for adding delicate details to artwork or accommodating individuals with smaller handwriting. Additionally, certain lead sizes are functionally equivalent, such as 0.3 mm and 0.35 mm, or 1.15 mm and 1.18 mm, providing users with even more options.
Moving up in thickness, lead sizes of 0.5 mm and 0.7 mm are commonly used and offer a balance between fine writing and broader strokes. Introduced by Pentel in 1962, these lead sizes revolutionized mechanical pencils by replacing clay with polymers, strengthening the lead and enabling smaller diameters. For those seeking an even bolder line, lead sizes of 1.0 mm, 1.3 mm, and 1.4 mm are available, with 1.4 mm being the upper limit for legible handwriting.
For sketching and shading purposes, lead sizes of 2.0 mm and above are available, with some pencils accommodating lead sizes up to 5.6 mm. These thicker leads are often used in clutch pencils, which hold the lead in place with a clutch mechanism or jaws. While these larger lead sizes require sharpening, they offer more coverage and can still produce relatively fine points. Overall, the variety of lead sizes available in plastic mechanical pencils showcases their versatility and adaptability to various tasks, from intricate writing to artistic endeavours.

Plastic mechanical pencils are cheaper than metal ones
Plastic mechanical pencils are generally more affordable than their metal counterparts. While both types of pencils are widely available and offer a range of features, plastic mechanical pencils tend to be cheaper. This is partly due to the materials used in their construction.
Plastic mechanical pencils are made primarily from plastic, as the name suggests. The body of the pencil is usually crafted from high-impact ABS (Acrylonitrile Butadiene Styrene) plastic, which is known for its durability and toughness. This type of plastic is also lightweight, making the pencil comfortable for extended use. Additionally, plastic mechanical pencils often feature ergonomic designs, with various shapes like triangles and balls, to reduce user fatigue.
In contrast, metal mechanical pencils tend to be more expensive due to the higher cost of metal materials. Metal body pencils are generally tougher and more durable than plastic ones, making them a popular choice for those seeking a long-lasting writing instrument. However, this increased durability comes at a higher price point.
Price is not the only factor that distinguishes these two types of mechanical pencils. The choice between a plastic and a metal mechanical pencil often comes down to personal preference and intended use. Some users may prefer the lighter weight and ergonomic features of plastic mechanical pencils, while others may opt for the durability and toughness of metal ones. Additionally, the availability of different lead sizes and grades can influence the decision, as plastic mechanical pencils typically offer a wider range of options to accommodate diverse user needs.
In summary, plastic mechanical pencils offer a cost-effective alternative to their metal counterparts. With their durable plastic construction, lightweight design, and ergonomic features, plastic mechanical pencils provide a functional and user-friendly writing experience at a more affordable price point than metal mechanical pencils.

Frequently asked questions
Mechanical pencils are made of plastic or metal. The plastic body of a mechanical pencil is usually made from high-impact ABS plastic, which is hard, tough, firm, durable, and has excellent chemical resistance and dimensional features.
Plastic mechanical pencils are lighter in weight and less prone to fatigue during long-term use. They are also more user-friendly and have a richer appearance design with more choices.
A cheap plastic pencil may not look the part in a meeting. If you want a tougher build, a metal body is likely to be more durable.
First, determine what is covering the opening of the internal lead tube (this could be an eraser, an eraser cap, or a single unit with an eraser inside). Then, remove the cover and, if necessary, the eraser. Next, locate the internal lead tube (this may be a plastic or metal tube inside the barrel of the pencil). Drop three to five leads into the tube, put the cover back in place, and click the push button until the new lead is extended.
