Vocabulary Focus:
Let’s review some key vocabulary related to pencil production and manufacturing. Please match the terms with their definitions and example usage:
Term | Definition | Example Usage |
---|---|---|
Graphite | A naturally occurring form of carbon used in pencil production. | The pencil’s core is made of a mixture of graphite and clay. |
Cedar Wood | A type of wood often used in pencil production due to its durability and sustainability. | The pencils are made with cedar wood to ensure a smooth writing experience. |
Pencil Lead Hardness | The level of hardness or softness of a pencil lead, determined by the ratio of graphite to clay. | The artist preferred a softer pencil lead for sketching. |
Vulcanization | A process of applying heat and pressure to transform raw rubber into a more durable and resilient form. | The eraser manufacturing process involves vulcanization to create a durable product. |
Ferrule | A metal or plastic piece used to attach the eraser to the pencil. | The ferrule holds the eraser in place, ensuring it doesn’t come loose during use. |
Extrusion | A process of shaping a material, such as rubber or graphite, into a desired form. | The graphite mixture is extruded into rods, which are then cut to size. |
Sanding | A process of smoothing the surface of a material, such as wood or graphite. | The pencils undergo sanding to smoothen their surfaces and improve appearance. |
Quality Control | A process of ensuring that products meet certain standards or requirements. | The company has a strict quality control process to ensure that all pencils meet the required standards. |
Market Size | The total value of a particular market or industry. | The global pencil market size is expected to increase by 7% by 2028. |
Sustainable Forestry | A practice of managing forests to ensure their long-term health and productivity. | The company sources its wood from sustainable forestry practices to reduce its environmental impact. |
