Plastic helps protect the internal components from moisture and physical damage, ensuring the cameras can withstand harsh conditions and continue to function accurately.

Lastly, plastic is a cost-effective material, making it possible to produce trail cameras at a range of price points. This accessibility allows both professionals and enthusiasts to utilise trail camera technology for a variety of applications, from wildlife research to home security.

China is the leading producer of plastic, but the US produces around 20%

Plastic is used in trail cameras as the outer protective covering. China is the world's leading producer of plastic, accounting for 32% of global plastic production in 2022. The Asian continent, excluding China and Japan, contributed an additional 19% to the global total. North America, including the US, produced 17% of the world's plastic in 2022, which is not an insignificant amount.

China's plastic production has been steadily increasing over the years, rising from 26% in 2014 to 32% in 2021. The country's monthly output ranges between 6 and 12 million metric tons, with the highest monthly production recorded in December 2021 at 7.95 million metric tons. China's dominance in plastic production is not surprising given its position as the world's leading manufacturing economy and exporter of goods.

The US produces around 20% of the world's plastic, contributing significantly to the North American share. While the majority of plastic comes from China and Asia, the US still plays a crucial role in the global plastic industry.

The global production of plastics surpassed 400 million metric tons in 2022, and it is projected to reach more than 1.2 billion metric tons by 2060. With the continuous growth of China's plastic export volume and the transition towards eco-friendly practices, the industry is focusing more on technological innovation.

The US does have local producers of the parts required to make trail cameras, and it is possible to find trail cameras made with US-produced plastic. However, it is challenging to find cameras that are entirely made in the US due to the many internal components involved.

Glass-filled polycarbonate is used in camera bodies

Glass-filled polycarbonate is a popular material for camera bodies, offering a range of benefits that make it a preferred choice over other materials like magnesium alloy. This material combines the advantages of both glass and polycarbonate, resulting in a durable and versatile option for camera manufacturers.

Firstly, glass-filled polycarbonate provides improved impact resistance compared to pure polycarbonate. This enhanced durability is crucial for trail cameras, which are often exposed to challenging environmental conditions, including rain, wind, and freezing temperatures. The impact resistance of glass-filled polycarbonate ensures that the camera can withstand accidental drops or bumps without cracking or shattering.

Additionally, glass-filled polycarbonate offers superior moisture and chemical resistance. Trail cameras are frequently used in outdoor environments with varying weather conditions, and the moisture resistance of this material helps protect the sensitive internal components of the camera. Its chemical resistance is also advantageous, as it prevents corrosion and degradation over time.

Another benefit of glass-filled polycarbonate is its optical transparency. This feature is particularly useful for camera bodies, as it allows for clear viewing and image capture. The optical properties of glass-filled polycarbonate are comparable to those of glass, providing excellent image quality without the weight and fragility associated with glass.

Moreover, glass-filled polycarbonate is a versatile material that can be easily worked, moulded, and thermoformed. This versatility enables camera manufacturers to create complex shapes and incorporate additional functions into the camera body. It also simplifies the manufacturing process, reducing production costs.

In terms of weight, glass-filled polycarbonate is lighter than metal alloys like magnesium. This lightweight property is advantageous for trail cameras as it makes them more portable and easier to mount or carry during outdoor activities. The reduced weight also contributes to the overall durability of the camera by reducing the stress on its structural components.

While magnesium alloy is also a popular choice for camera bodies, it has some drawbacks. Magnesium alloy requires additional processing steps, such as deburring, after the initial manufacturing process. It is also more challenging to incorporate complex functions into magnesium alloy camera bodies, limiting their versatility.

In summary, glass-filled polycarbonate is an ideal material for trail camera bodies due to its impact resistance, moisture and chemical resistance, optical transparency, versatility, and lightweight nature. These properties contribute to the durability, functionality, and ease of manufacturing of trail cameras, making glass-filled polycarbonate a preferred choice in the industry.

Glass-filled nylon is very hard and used in knife handles

Plastic is used in trail cameras as the outer protective covering. While China is the leading producer of plastic, the USA produces around 20% of the world's plastic supply.

Glass-filled nylon is a very hard material used in knife handles. Nylon is a popular material for knife handles because of its strength, impact resistance, chemical inertness, and stability at high temperatures. By adding glass fibres to the nylon, the resulting glass-reinforced nylon (GRN) is even stronger. GRN is a thermoplastic material that is relatively cheap and practically indestructible. It can be moulded into almost any shape and textured in numerous ways.

The glass fibres used to produce GRN are long, textile-type strands with a lubricant to prevent them from abrading each other. Binders and coupling agents are added to help the fibres bind with the nylon. This reinforcement at least doubles most of the physical properties of the nylon, increasing tensile strength and deflection temperature. Similar increases can be seen in dimensional stability, fatigue endurance, and resistance to hydrocarbons found in gasoline, machine oils, and other industrial products.

The use of GRN in knife handles helps to decrease the property known as creep, which is the movement of the blade in its fitting in the handle. Deformation under repeated impacts, a common problem with conventional nylon, is also improved. Knives made with GRN handles last longer, resist wear better, and remain usable over a broader range of conditions than those with conventional nylon handles. GRN's ability to retain its shape under high temperatures and resist solvents, fuels, and other caustic chemicals, makes it ideal for survival applications where equipment failure can have life-threatening implications.

Plastic is combined with other materials to make trail cameras

Plastic is a common material used in the outer protective covering of trail cameras. However, it is often combined with other materials to enhance the durability, functionality, and aesthetics of the device.

One example of this is the use of glass-filled plastic, which is a composite material that combines the benefits of both glass and plastic. Glass-filled plastic offers improved impact resistance, moisture resistance, and chemical resistance compared to standard plastic. It has a harder and less "cheap" feel, making it a suitable choice for camera bodies.

Additionally, some trail cameras may utilise an aluminium skeleton underneath the plastic outer shell. This metal structure provides added strength and rigidity to the device, ensuring it can withstand various environmental conditions and potential impacts.

The lens barrel of trail cameras may also incorporate plastic. In some cases, manufacturers use a combination of engineering-grade plastics, such as Nylon 6-6 or Ultra-high-molecular-weight polyethylene, to create more rugged composites for this component.

Furthermore, trail cameras often feature an LCD screen, which is typically made of glass or plastic. This screen allows users to view and compose images, adjust settings, and review captured photos or videos.

It is worth noting that the specific combination of materials used in trail cameras can vary among different brands and models, and manufacturers are constantly innovating to improve the performance and durability of their products.
