Creating Plastic Products: Understanding The Cost Factors

Plastic is used to fabricate products in every major industry, from medical to automotive, electronics, and housewares. The cost of making a plastic product depends on a variety of factors, including the number of plastic components, the finish, and the type of mould used. A simple mould can cost as little as $1,000, but prices can quickly escalate depending on the complexity of the design and the number of parts required. The manufacturer will also typically charge an hourly rate per moulding machine, which is then converted to a cost per part.

The cost of a mould

Another factor that affects the cost of a mould is the finish. If a surface is visible, it should be finished to a certain degree. The finer the finish, the more it will cost. Large surface areas with a high polish can be very expensive. Similarly, textured surfaces are extremely expensive. These finishing processes are more precise, remove much less material than standard machining processes, and require more oversight and thus take more time and cost more money.

The setup fee charged for a mould typically doesn’t provide profit to the manufacturer. The manufacturer is only seeking to cover their expenses, understanding that customers tend to be averse to a large setup charge. The manufacturer will typically have an hourly rate that they charge per moulding machine. However, this hourly rate doesn’t have any meaning to customers, so it is converted to a cost per part.

It is important to note that the cost of a mould is just one component of the overall cost of manufacturing a plastic product. Other factors, such as the cost of the plastic material and the labour involved, will also play a role in determining the final price.

The cost of the finish

To keep costs down, it is advisable to remove any unnecessary polishes and textures that are not critical to the function or aesthetics of the product. For instance, if a surface is not visible to the end user, there is no need to spend extra on a high-quality finish.

The number of cavities in a mould also impacts the cost of plastic manufacturing. Cavitation can help to reduce costs, and manufacturers will often create multiple moulds with different cavity configurations to optimise production.

Another cost to consider is the setup fee charged by the manufacturer. This typically covers their expenses and does not provide a profit. Manufacturers will try to minimise the number of setups as they are expensive and disruptive to normal manufacturing. They will usually charge an hourly rate per moulding machine, which is then converted to a cost per part for the customer.

The cost of the setup

The finish of the product will also impact the cost of the setup. Large surface areas with a high polish can be very expensive, as can textured surfaces. These finishing processes are more precise, remove less material, and require more oversight, taking more time and costing more money.

To keep costs down, you can remove any unnecessary polishes and textures that are not critical to the function or aesthetics of the product. For example, seals or surfaces that are not visible to the end user.

The cost of the machine

The manufacturer will also have an hourly rate that they charge per moulding machine, which is converted to a cost per part. This is to cover their expenses, as customers tend to be averse to large setup charges.

The cost of the material

The number of cavities in a mould directly impacts the cost per part. A higher number of cavities means more parts can be produced in a single cycle, reducing the overall cost per part. This is a key consideration for manufacturers, as it can significantly impact the profitability of a product.

The finish of a plastic product also affects its cost. A high polish or textured surface can be extremely expensive, as these finishes require more precise and time-consuming manufacturing processes. Removing unnecessary polishes and textures can help to reduce costs, but this must be balanced with the functional and aesthetic requirements of the product.

The size and complexity of a mould also play a role in determining the cost of the material. Larger moulds require more plastic material, which increases the cost. Additionally, complex shapes may require more intricate mould designs, driving up the price. Manufacturers may also charge an hourly rate per moulding machine, which can add to the overall cost of the material.

It is important to note that the cost of the material is just one aspect of the overall price of a plastic product. Other factors, such as labour, overhead costs, and profit margins, also come into play. However, by understanding the factors that influence the cost of the material, manufacturers can make informed decisions to optimise their production processes and pricing strategies.
