When it comes to plastic manufacturing, both blow moulding and rotational moulding (rotomoulding) are widely used processes. Are there misconceptions surrounding each? Let’s break down the facts and bust a few common myths along the way so you can make an informed decision.
Myth 1: Blow Moulding Product are always economical compared to rotational moulding products
Busted: While blow moulding may offer cost advantages for high-volume production of smaller parts, rotational moulding is more cost-effective for larger, hollow, and low-volume products. Why? Because rotomoulding has lower tooling and setup costs, making it ideal for customised and small-batch production.
Myth 2 : Blow Moulded Products Are Just as Durable as Rotomoulded Ones
Busted: Rotomoulded products are often more durable due to their seamless, stress-free construction. The even wall thickness achieved during rotomoulding results in products that are more resistant to impact and environmental stress. In contrast, blow moulded products have limitations to thickness of tank, making them not suitable for larger capacity tanks (500+ litres).
Myth 3: Only Blow Moulding Can Achieve Complex Shapes
Busted: Rotomoulding actually excels at producing complex, hollow, and custom-shaped parts. Unlike blow moulding, which has design constraints due to its process, rotomoulding allows for greater design freedom, including intricate geometries, textures, and even embedded logos.
Myth 4: Rotomoulding Is Just for Tanks
Busted: While rotomoulding is famous for water tanks and storage containers, it’s used in automotive parts, playground equipment, furniture, pontoons, buoys, and more. The idea that it’s a one-trick pony is outdated.
Myth 5: Blow Moulding Is Better for Consistency
Busted: With today’s advancements in rotomoulding, consistency is no longer an issue. Modern rotomoulding machines use advanced temperature control and automated systems to deliver uniform results, especially for medium to large-sized products.
Myth 6 Blow Moulded and Rotational Moulded Tanks Offer the Same Capacity Options
While both processes create water tanks, rotational moulding offers a much wider range of sizes, from small residential tanks to massive industrial storage solutions (from 10 litres to 10,000+ litres). In contrast, blow moulded tanks are typically limited to smaller capacities commonly 200L to 1000L making them less versatile for high-volume or commercial applications.
So, Which One Is Right for You?
If you’re looking for durable, robust, and plastic products, rotational moulding often wins out especially when it comes to applications like water tanks, storage containers, and industrial solutions.If you are looking for a short term solution or temporary solution, or a small product, blow moulding can be right.
