Initial grounds for introduction of an HR system

As may be seen, the analysis includes not only measurable economic aspects, but also in many cases non-measurable considerations of a technical, organisational and quality nature. Performance of an analysis that takes into account the specific nature of the product in question builds on the general lists of advantages and drawbacks to HR use that was discussed in Section 2.1. In specific sections the study may be made in a general way, as an estimation, or even with detailed calculations (see Section 2.3). 

Savings on materials and labour. A determination is made of the reduction in production costs resulting from the elimination or diminution of waste in the form of sprues and runners. 

Increasing production through shortening of the cooling time and machine times and automation of work  

Simplified production. After sprues and runners are eliminated, automatic separators or manual sorting to separate them from the mouldings are no longer required, which makes the automation of work easier. 

Improved utilisation of injection moulding machines. Use of moulds with HR makes it possible to
