Plastic Injection Molds: Understanding The Cost Factors

Plastic injection moulds can cost anywhere from $100 to $100,000+, depending on the size, complexity, material, and anticipated quantities of the project. A small and simple single-cavity plastic injection mould usually costs between $1,000 and $5,000, while very large or complex moulds may cost as much as $80,000 or more. On average, a typical mould that produces a relatively simple part small enough to hold in your hand costs around $12,000. In this article, we will explore the factors that influence the cost of plastic injection moulds and provide tips on how to estimate the cost of your project.

Cost range: $100 to $100,000+ depending on the project

The cost of a plastic injection mould can vary significantly depending on the scope and intricacy of the project. Prices can range from as little as $100 for a 3D-printed low-volume injection mould to upwards of $100,000 for a complex multi-cavity steel mould designed for high-volume production.

A small and simple single-cavity plastic injection mould typically costs between $1,000 and $5,000, while more complex or larger moulds can reach prices of up to $80,000 or more. On average, a typical mould that produces a relatively simple, small part costs around $12,000.

The price of a mould is just the beginning, as the total injection moulding cost depends on various factors, including the part size, complexity, material, and anticipated quantities. For instance, a single-cavity mould that produces 1,000 washers per year would likely cost between $1,000 and $2,000, whereas a mould for 100,000 Xbox controllers every month would be significantly more expensive.

The cost of the mould should be weighed against the number of parts being produced, as higher production numbers will lower the final per-piece cost. Injection moulding is an ideal process for mass-producing plastic parts affordably, as the fixed start-up costs can be distributed among hundreds or thousands of units.

Price per unit: one of the cheapest forms of manufacturing

Plastic injection moulding is one of the most cost-efficient forms of manufacturing. The more units you create with your mould, the cheaper the price per unit becomes. This is because the total injection mould cost can be spread out over hundreds or thousands of parts.

The cost of your mould will depend on a combination of factors, including the part size, complexity, material, and anticipated quantities. For example, a small and simple single-cavity plastic injection mould usually costs between $1,000 and $5,000. On the other hand, a complex multi-cavity steel mould for high-volume production can cost $100,000 or more.

If you only need a small number of parts, a small desktop injection moulding machine is the most cost-effective choice. These machines are perfect for in-house projects and can produce low volumes of parts at a low cost.

Overall, the price of a plastic injection mould can range anywhere from $100 to $100,000 or more, depending on your specific needs and requirements.

Cost of plastic pellets: $1 to $5 per kg

The cost of plastic injection moulding varies depending on the scope and intricacy of the project. A small and simple single-cavity plastic injection mould usually costs between $1,000 and $5,000, while very large or complex moulds may cost as much as $80,000 or more. On average, a typical mould that produces a relatively simple part small enough to hold in your hand costs around $12,000.

The cost of the plastic pellets used in the injection moulding process is a significant factor in the overall cost. Plastic pellets can range in price from $1 to $5 per kg, depending on the type of plastic and the quantity purchased. For example, a common type of plastic pellet used in injection moulding, such as ABS (acrylonitrile butadiene styrene), typically costs around $2 to $3 per kg.

The cost of plastic pellets can also vary depending on the colour and any additives that may be included. For instance, pellets with special additives to enhance impact resistance or UV stability may be more expensive. Additionally, the quantity purchased can impact the price per kg, with larger orders often resulting in a lower cost per kg.

When considering the cost of plastic injection moulding, it is essential to factor in the price of the plastic pellets, as this can significantly impact the overall cost of the project. By understanding the cost of the pellets and the quantity required for the project, you can better estimate the total expense of the injection moulding process.

Cost of a small desktop injection moulding machine: the cheapest option

The cost of a small desktop injection moulding machine is the cheapest option for producing low volumes of parts. The price of a small and simple single-cavity plastic injection mould usually falls between $1,000 and $5,000, but can be as low as $100 for a 3D-printed low-volume injection mould. The price of a mould depends on the size, complexity, material, and anticipated quantities of the part. For example, if you wanted 1,000 washers per year, a single-cavity mould would cost around $1,000 to $2,000. However, if you needed 100,000 Xbox controllers every month, the price would be significantly higher.

The cost of injection moulding can range from $3,000 to $100,000 or more, with simple moulds typically costing between $3,000 and $6,000. The price increases for large, more complex, high-production, or multi-cavity moulds, which can cost $25,000 to $50,000 or more. The cost of the mould should be weighed against the number of parts being produced, as higher production numbers will lower the final per-piece cost.

Overall, the price of a small desktop injection moulding machine will depend on the specific requirements of the project, but it is a cost-effective option for producing low volumes of parts.

Cost of outsourcing: cheaper than buying a machine

Injection moulding can be an expensive process, with costs ranging from $100 to $100,000+. The price depends on the scope and intricacy of the project. A small and simple single-cavity plastic injection mould usually costs between $1,000 and $5,000, while very large or complex moulds may cost as much as $80,000 or more. On average, a typical mould that produces a relatively simple part small enough to hold in your hand costs around $12,000.

The cost of outsourcing injection moulding is likely to be cheaper than buying a machine, especially if you only need a small number of parts. Injection moulding is one of the cheapest and most cost-efficient forms of manufacturing when looking at the price per unit. The more units you create with your mould, the cheaper the price per unit becomes. This is because the total injection mould cost can be spread out over hundreds or thousands of parts.

For example, if you wanted 1,000 washers per year, a single-cavity mould would cost around $1,000-$2,000. However, if you needed 100,000 Xbox controllers every month, the cost would be significantly higher.

The cheapest option for injection moulding is a small desktop injection moulding machine, which is perfect for in-house projects and low-volume parts production. However, even this machine may be an unnecessary expense if you only need a small number of parts and can outsource the production instead.

Outsourcing injection moulding can also save you time and resources, as you won't need to invest in the training and maintenance required to operate the machine yourself.
