Why is injection mould processing expensive?

In our daily life, many products such as household appliances, mobile phone shells, automotive parts and so on, are inseparable from the injection mould precision processing. However, the price of injection mould processing is prohibitive for many people. So, why is injection mould processing so expensive? The following aspects are the reasons for the high cost of injection mould processing.

1. Design and R&D cost

The design and development of injection moulds is a complex and time-consuming process. Designers need to make several modifications and optimisations according to the needs of the product to ensure that the mould can meet the production requirements. In this process, a lot of human, material and financial resources may be required.

2. Material cost

The materials of injection moulds are usually made of high-strength and high-hardness steel, which are expensive and need to be treated with heat treatment, quenching and other processes to improve the wear resistance and service life of the moulds. In addition, in order to ensure the precision and stability of the mould, it also needs to be finely polished and ground. All these processes will lead to the increase of material cost.

3. Manufacturing process cost

The manufacturing process of injection moulds is very complex and requires multiple processes to complete, including roughing → semi-finishing → finishing → assembly, debugging and inspection. In this process, it is necessary to use a variety of high-precision equipment, equipment acquisition and maintenance costs are very high. Therefore, the cost of manufacturing process is also an important factor affecting the price of injection mould processing.

4. Accuracy and life requirements

The precision of injection moulds directly affects the quality and dimensional stability of plastic products. In order to meet these requirements, mould manufacturers need to adopt advanced processing technology and equipment, as well as strict quality control system. It will also increase the cost of injection mould processing.

So the price of injection mould processing is high because it involves the cost of design, research and development, materials, manufacturing process and many other aspects.
