ABSTRACT
Most very large moulds are manufactured in Europe, especially in Germany and Italy. The main reason being that South Africa does not have enough very large size CNC machines on which these could be machined. A large size mould half can be split into two or more smaller parts for machining purposes and then reassembled later. In this way many large size moulds, especially rotational moulds can be manufactured on medium size CNC machines. Since the large component has been split into small parts, these can be distributed to different subcontractors to machine simultaneously, and thereby reducing the total manufacturing lead-time. The project then uses three case studies to advance the proposed concept for mould manufacture. A small size rotational mould for a model drum is manufactured to confirm that Pentech had both the

    2). The competitive priorities for each of the individual processes are the quality, cost effectiveness and customer responsiveness. The changing nature of the industry was in the tendency of manufacturers to develop strategic partnerships with suppliers. Hence, more and more demand for responsiveness was laid upon suppliers to sustain the competition. In the Custom Molds' case, as order for multiple molds began declining, the responsiveness of the individual processes began suffering due to the capacity constrains (bottlenecks) at different stages of operations. This naturally entailed the lost sales to customers.…

    Looking at the workflow of Custom Molds raises several questions. First, customers’ complaints about delivery delays have increased. The voice of the customer always signals a problem. Tom and Mason Miller now have to identify where that problem lies and how it can be solved. Following the 6 step analysis presented by the authors of Operation Management Strategy and Operations [Krajewski J. Lee, 2001], the first step is to identify where there is a gap between what the customer expects and what the company can deliver. Clearly, Custom Molds has a too long lead time and is not respecting its deadlines. The company’s managers might start by looking at the relationship with the suppliers and analyzing the complaints from customers.…
