Understanding the Cost Implications of Cavities in Plastic Injection Mould Tools 

Introduction: 

Plastic injection moulding is a widely used manufacturing process that involves melting plastic pellets and injecting them into a mould tool to create various plastic products. The mould tool is a critical component of the injection moulding process, and its cost can significantly impact the overall production cost. One factor that affects the cost of the mould tool is the number of cavities in the tool. In this blog post, we will discuss the cost implications of cavities in plastic injection mould tools. 

Cost of Mould Tool: 

The cost of the mould tool is a significant factor that affects the production cost. A mould tool with more cavities is generally more expensive than a tool with fewer cavities. The cost of the tool depends on various factors, such as the tool’s material, complexity, size, tolerance requirements, surface finish, and maintenance. 

Production Volume: 

The production volume is another critical factor that affects the cost of the mould tool. A mould tool with multiple cavities can produce more parts in a single cycle, reducing the production time and cost per part. However, the cost of the tool must be weighed against the production volume required. If the production volume is low, a mould tool with fewer cavities may be more cost-effective. 

Part Complexity: 

The complexity of the part being produced also affects the cost of the mould tool. A complex part with intricate features and tight tolerances may require a mould tool with fewer cavities to ensure that the part is produced with the required quality and consistency. On the other hand, a simple part with minimal features may allow for a mould tool with more cavities, reducing the production cost per part. 

Material Costs: 

The material cost of the plastic resin used to create the part also affects the cost of the mould tool. A mould tool with more cavities requires more plastic resin per cycle, resulting in higher material costs. However, if the production volume is high, the cost per part may be lower, making a mould tool with more cavities more cost-effective. 

Machine Costs: 

The machine used to produce the parts also affects the cost of the mould tool. A mould tool with more cavities requires a larger and more expensive machine to handle the increased production output. However, if the production volume is high, the cost per part may be lower, making a mould tool with more cavities more cost-effective. 

Time to Produce Parts: 

The time required to produce the parts also affects the cost of the mould tool. A mould tool with more cavities can produce more parts in a single cycle, reducing the production time and cost per part. However, the time required to produce the mould tool itself may be longer for a tool with more cavities, resulting in higher initial costs. 

Conclusion: 

The number of cavities in a plastic injection mould tool significantly affects the cost of the tool and the production cost per part. Manufacturers must consider various factors such as the production volume, part complexity, material costs, machine costs, and time required to produce the parts to determine the most cost-effective number of cavities for the mould tool. By selecting the appropriate number of cavities, manufacturers can optimize their production process and reduce costs while maintaining the required quality and consistency of their products.
