Manufacturing throughput time

To minimize the cost of manufacture, one approach is to minimize the manufacturing throughput" time, sometimes called just in time or the Toyota lean manufacturing process. ...

Using the new designs, Tom was now able to reorganise the factory into cells that produced major subassemblies such as rotors and stators. The work flow was transformed, and manufacturing throughput time was reduced from six weeks to just four days. Cost improvements meant that average price reductions of between 10 and 15 per cent could be offered. 

Throughput is best understood as the time required to produce a quantity of average saleable product and cycle time is best understood as the average rate at which products are manufactured. Throughput will be affected by such things as the efficiency and rate of chemical conversion, the isolated process yield, plant capacity, the availability of equipment, process time, cycle time, the number of chemical steps, the number of unit operations, plant layout, warehouse processes, raw material availability, process bottlenecks, labor availability, and others.

Recrystallization time is very useful for the development of processing times for recrystallization upon cooling from the melting temperature. Recrystallization time is measured in an isothermic experiment in which the material is cooled to a predefined temperature and then held there iso-thermally until the recrystallization is complete. The time it takes to recrystallize is measured. A slight shift in mold temperature often saves time, thus increasing manufacturing throughput. The sensitivity and temperature control of a power-compensation DSC is ideal for this experiment (Fig. 9). 

Test throughput is not always fast enough to allow inspection of all solder joints within the manufacturing cycle time for the printed circuit assembly. 

Assume that this book will show you how you, too, can have this success. What is stopping you from continuing to reduce throughput times Not just in manufacturing, but also in the upstream divisions, such as development, design, purchasing, work preparation, etc. The earnings potential is enormous. 

Many businesses have invested heavily in automation in the factory with the aim of reducing throughput times. In some cases processes that used to take days to complete now only take hours and activities that took hours now only take minutes. However, it is paradoxical that many of those same businesses that have spent millions of pounds on automation to speed up the time it takes to manufacture a product are then content to let it sit in a distribution centre or warehouse for weeks waiting to be sold The requirement is to look across the different stages in the supply chain to see how time as a whole can be reduced through re-engineering the way the chain is structured. 

There can be different approaches to tracking throughput either volume of product or material manufactured per unit of time, number of products per unit time, mass per unit time, and so on. 

One problem is how to optimize throughput (analysis time) without losing peak capacity. Different approaches have been suggested and led to different developments by instrument and column manufacturers. This section will concentrate on the usage of totally porous particle columns for chromatographic separation only. Alternatives are monolithic columns9 and shell packing materials such as Halo or Poroshell.10-13...
