Plastic Molding Cost: Customization's Impact On Your Wallet

Injection molding costs vary significantly depending on the scope and complexity of the project. The price of a mold can range from $100 for a 3D-printed low-volume injection mold to $100,000+ for a complex multi-cavity steel mold for high-volume production. The type of plastic resin used also impacts the cost, with prices ranging from $2 to $20 per pound. Other factors that influence the overall cost include mold upkeep, part rate, estimated scrap amount, plastic weight, and labor training.

Cost of plastic resins

The cost of plastic resins can range from $2 to $20 per pound. The amount of plastic used in each injection depends on the size and complexity of the mould. For example, a small and simple single-cavity plastic injection mould usually costs between $1,000 and $5,000, while a very large or complex mould may cost as much as $80,000 or more.

The cost of plastic resins is just one factor that contributes to the overall cost of custom plastic moulding. Other factors include the cost of the mould itself, the cost of labour, and the cost of maintenance and monitoring.

The cost of the mould can vary depending on the material used. For example, a 3D printed low-volume injection mould can cost as little as $100, while a complex multi-cavity steel mould for high-volume production can cost $100,000 or more.

The cost of labour is also a significant factor, as skilled labour can be expensive. In addition, the cost of maintenance and monitoring can add to the overall cost, as these activities require specialised knowledge and equipment.

Overall, the cost of custom plastic moulding can vary widely depending on a number of factors, including the cost of plastic resins, the cost of the mould, the cost of labour, and the cost of maintenance and monitoring. It is important for businesses to carefully consider these factors when planning a custom plastic moulding project to ensure that they are able to manage the costs effectively.

Cost of injection moulding machines

The cost of injection moulding machines varies depending on the scope and intricacy of the project. Injection moulding tooling costs increase exponentially for large custom-designed parts. Small (desktop) injection moulding machines are used for low-volume orders, while large, industrial plastic injection moulding machines are used for high-volume orders and can cost over $200,000.

The cost of plastic resins ranges from $2 to $20 per pound, and the amount of plastic used in each injection depends on the mould size and complexity. 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.

Simple low-volume 3D printed moulds can be produced for as little as $100, while an aluminium mould for a mid-volume production run of approximately 1,000-5,000 units costs between $2,000 and $5,000. For moulds with more complex geometries and larger production runs of approximately 10,000+ units, the cost can range from $5,000 to $100,000.

The cost of purchasing materials for moulds differs according to the material chosen, and the cost of injection-moulded parts varies based on mould upkeep, the time to form a part, the part rate, the estimated amount of scrap, the plastic weight, and sometimes a mould maintenance fee, which covers the cost of injection mould warranties.

Cost of labour

The cost of labour for custom plastic moulding 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 labour for injection moulding can also vary depending on the type of machine used. Large, industrial plastic injection moulding machines can cost over $200,000 and have additional costs related to skilled labour training, maintenance, monitoring, and industry regulations. These machines are typically reserved for high-volume orders.

The cost of plastic resins, which are used to create the moulds, can range from $2 to $20 per pound. The amount of plastic used in each injection will depend on the mould size and complexity.

It's important to note that the cost of labour is just one factor in the overall cost of custom plastic moulding. Other factors include the cost of the mould itself, the cost of materials, and any additional costs such as maintenance or warranties.

Cost of maintenance

The cost of custom plastic moulding varies depending on the size, complexity of the design, and the material used for the mould. For example, a small part with a complex design could cost between $20,000 and $40,000 to mould, whereas a large part with a simple design could cost between $30,000 and $100,000. If the part is large but has no design work, an additional $10,000 will be added for design. The more complex the part, the more time it takes to make the mould, and time is money.

Some parts may require additional features such as cams, lifts, or core pins, which increase the cost. If the part has a higher volume, the mould would require more cavitation, which also adds to the cost. The type of resin used also affects the price; commodity-grade resins are typically less expensive than engineering-grade resins, which can withstand extreme temperatures and friction better.

The cost of maintenance for custom plastic moulding depends on several factors, including the frequency of use, the environment in which it is used, and the quality of the mould. Regular maintenance is essential to ensure the mould is in good condition and to prevent costly repairs or replacements. This includes cleaning, lubricating, and inspecting the mould for any signs of wear or damage.

The frequency of maintenance will depend on how often the mould is used and the type of material it is made from. For example, if the mould is used frequently and is made from a material that is prone to wear and tear, it may need to be maintained more often. Additionally, if the mould is used in a harsh environment, such as one with extreme temperatures or corrosive chemicals, it may require more frequent maintenance to prevent damage.

The cost of maintenance can vary depending on the severity of the issue. Minor issues, such as cleaning or lubricating the mould, may only require a small investment in time and materials. However, more significant issues, such as repairing or replacing damaged components, can be much more costly. In some cases, it may be more cost-effective to invest in a new mould rather than repairing an old one.

It is important to consider the long-term costs of maintenance when deciding on a custom plastic moulding project. While the initial investment in a high-quality mould may be higher, it can save money in the long run by reducing the frequency and cost of maintenance. Additionally, choosing a mould made from a durable material that is resistant to wear and tear can also help to reduce maintenance costs over time.

Cost of plastic weight

The cost of custom plastic moulding depends on a variety of factors, including the size, complexity of design, and material used for the mould. For example, a small part (1” square) with a good design can be prototyped for under $100, whereas a small part with no design could cost around $2,000 for design work and under $100 for the prototype. Similarly, a small part with a complex design could have a mould cost between $20,000 and $40,000.

The cost of custom plastic moulding can also be affected by the demand for the part. If the demand is very high (hundreds of thousands of pieces), a multi-cavity tool may be required, which increases the cost. For large parts with a simple design, the mould could cost between $30,000 and $100,000. If the part is large but has no design work, an additional $10,000 may be added for design.

The material used for the mould can also impact the cost. There are over 100 different varieties of resin, and the ideal plastic material depends on the characteristics and end use of the part. Commodity-grade resins are typically less expensive than engineering-grade resins, which can withstand extreme temperatures and friction better.

Overall, the price of custom plastic moulding can range from as low as $3,000 to $30,000 or more, depending on the specific requirements and factors involved.
