Specialist Technical Principles

Hardwoods

Hardwoods

Woods from broad-leaved, deciduous trees (e.g., oak, mahogany) known for their durability and strength.

Softwoods

Woods from coniferous trees (e.g., pine, cedar) that are generally lighter and easier to work with.

Ferrous Metals

Metals containing iron, known for their strength and magnetic properties (e.g., steel, cast iron).

Non-Ferrous Metals

Metals that do not contain iron, known for their resistance to rust and corrosion (e.g., aluminum, copper).

Thermoplastics

Plastics that can be melted and reshaped multiple times (e.g., polyethylene, polystyrene).

Thermosetting Plastics

Plastics that harden permanently after being heated and shaped (e.g., epoxy, bakelite).

Natural Fibers

Fibers derived from plants or animals (e.g., cotton, wool) known for their biodegradability.

Synthetic Fibers

Man-made fibers produced from petrochemicals (e.g., polyester, nylon) known for their durability.

Composites

Materials made from two or more constituent materials with different properties (e.g., carbon fiber, fiberglass).

Tension

The force that pulls or stretches a material.

Compression

The force that compacts or squashes a material.

Bending

The force that causes a material to curve.

Torsion

The force that twists a material.

Shear

Forces that cause parts of a material to slide past each other in opposite directions.

Stress

The force per unit area within materials that arises from externally applied forces.

Strain

The deformation or displacement of a material relative to its original length.

Equilibrium

A state where all forces and moments are balanced, resulting in no movement.

Stability

The ability of a structure to remain unchanged or return to its original position after being disturbed.

Life Cycle Assessment (LCA)

A method to assess the environmental impact of a product from its creation to disposal.

One-off Production

Manufacturing of a single, unique product tailored to specific requirements.

Batch Production

Manufacturing a set number of identical products in groups or batches.

Mass Production

Large-scale manufacturing of standardized products, usually on assembly lines.

Continuous Production

Ongoing production without interruption, often used for high-demand products.

Anodizing

An electrochemical process that creates a durable oxide layer on aluminum.

Electroplating

A process of coating a metal object with a thin layer of another metal using electric current.

Galvanizing

Applying a protective zinc coating to steel or iron to prevent rusting.

Varnishing

Applying a protective and decorative finish to wood, providing a hard, clear, or colored surface.

Lacquering

Coating a material with lacquer to provide a durable, glossy finish.

Staining

Applying pigment to wood to enhance its color while allowing the grain to show.

Powder Coating

Applying a dry powder to a surface and curing it under heat to create a hard finish.
