Blow Moulded vs Injection Moulded Watering Cans

When it comes to choosing a watering can for your garden, you may have come across two common manufacturing methods: blow moulding and injection moulding. But what exactly are the differences between these two techniques? And which one is better for watering cans? Let's explore the pros and cons of blow moulded and injection moulded watering cans to help you make an informed decision. What is blow moulding? Blow moulding is a manufacturing process that involves inflating a heated plastic tube into the shape of a mould. This technique creates hollow objects, such as watering cans, with a seamless construction. The process begins with melting plastic resin, which is then extruded into a tube shape. The tube is clamped into a mould, and compressed air is blown into it, causing the plastic to expand and take the shape of the mould. What is injection moulding? Injection moulding, on the other hand, is a process where molten plastic is injected into a mould under high pressure. The plastic then cools and solidifies, resulting in the desired shape. Injection moulding is commonly used to produce solid objects, including watering cans. The process starts with the plastic resin being melted and injected into a mould cavity. Once the plastic has cooled and hardened, the mould opens, and the finished product is ejected. Advantages of blow moulded watering cans Blow moulded watering cans offer several advantages. Firstly, they are lightweight yet durable, making them easy to carry around the garden. The seamless construction of blow moulded cans also means they are less likely to leak or break, ensuring a longer lifespan. Additionally, blow moulding allows for more intricate and creative designs, giving you a wider range of options to choose from. Advantages of injection moulded watering cans Injection moulded watering cans have their own set of advantages. One of the main benefits is their sturdiness. The solid construction of injection moulded cans makes them more resistant to wear and tear, making them suitable for heavy-duty use. Injection moulding also allows for precise and consistent production, ensuring that each watering can is identical in shape and size. The Heritage Watering Can by etree is one of the few injection moulded watering cans available in the UK. It boasts the durability and sturdiness you'd get from a metal watering can, while being surprisingly light weight. Conclusion Both blow moulded and injection moulded watering cans have their merits. If you prioritize lightweight and creative designs, blow moulded cans may be the better choice for you. On the other hand, if durability and consistency are your top concerns, injection moulded cans are worth considering. Ultimately, the decision comes down to your specific needs and preferences. Whichever type of watering can you choose, make sure to select a high-quality product that will help you keep your plants hydrated and your garden flourishing.
