Abstract

The project aim to compare the performance of beryllium copper and NAK80 mould insert materials in plastic injection moulding. The experiment involved varying critical processing parameters like melting temperature and injection pressure, and considering design aspects like shrinkage level and weight of the mould part. The choice between BeCu and NAK80 depends on the specific requirements of the application and the relative importance of each factor. BeCu has a better cycle time and weight, making it suitable for high-volume production scenarios. The weight of the sample is better for BeCu, making it more durable. However, NAK80 has a higher shrinkage level, which is generally desirable as it leads to less dimensional change in the final product. Other factors, such as cost and availability, may also play a role in the decision
