Waste Reduction Engineering – A casting process
Waste: an unwanted or undesired material or substance (Wikipedia online encyclopedia). To an outsider, looking in the field of metal casting, it seems as if the substances that we often waste time and energy – and Could Well Be fair! In some foundries, these resources are not replaceable wasted – not recklessly, not intentionally – but because its design and production methods is based is based on outdated production methods.
Past-process engineering
In timesPast paper and pencil were the most important tools a designer had the casting – and the casting was a development of a process that was tedious and time consuming. A draft paper was prepared, the project was introduced to the wheel die – who graduated with a tool. Along with a cast - machine was selected, the process and mold develops layout and cost estimate. Citations were. The race winner has given permission to its producers with toolsSteel mold and begin to die. When finished, test die was to die for the wheel before. After the construction inside the machine, castings were produced and tested for flaws.
It was not until this point in the casting process that shares have the slightest idea about the quality. When the merger is not up to the standards required changes would be. Different settings and lower dieCorrections could die doing – casting machine immediately – but if the first attempt was that the shape is changed, the steel had to be sanded off and welded back in other places, and this work had to do to the structure tool vendor. The form was traveling back and forth between tool and die casters, an acceptable quality of castings up. The time between the beginning of the cast and good projects could ShippingWeeks, months or years, depending on the complexity and size.
Moreover, the drawings could mold – and – has changed, production has started well, and the changes could mean forms, these models have different designs, different age and wear, and various casting quality. In addition to the tool change, variability production parameters such as pressure die casting, casting speeds and transitions, the amount of lubrication and places, and solidificationCycle times changed throughout the merger process. The continuous need to adapt and improve the fusion ended only when the jet is no longer necessary. Working for a better quality of mergers has taken a great team of active engagement with the process engineers, operators, maintenance and die toolmakers, high quality office, casting design, casting, machining, assembly and materials also planning and management group.
Although there werea time when this type of "engineering" was required, the economic reality of today is not financially feasible in this way to do more – but even so, this "technique" may in society who are fighting their way through the find difficult moments.

Streamline the process today
With the addition of computers in factories, process engineering is constantly changing and increasingly slim. Casting no instruments are drawn on paper and size should not be converted into the mold designs. computer aided design permit available in three models of volume-dimensional information is transmitted at the touch of a button and be used directly as input in the treatment of steel equipment. Changes inModels can be made quickly and easily shared with all departments of planning.
The great value of computerization is the ability to develop, design and build almost the same time. These working conditions parallel decrease development time and accelerate time-to-market, a level not That dreamed of years ago. Computerisation in the process of designing and manufacturing shops Have a machining equipment allows even more precise in the instrument to measure dieSteels and heat treatments allow factors such as changes based on length of production cycle, and materials in direct contact with the merger or transfer of heat and heat flow.
One major change was in process improvement. With MAGMASOFT (r) simulation software, complete fusion process can be simulated, modified and optimized quickly available to the toolmaker. Casting simulation models informAbout the quality of production expected during the melting process – before being published. Based on simulation, changes to the system manifold casting, tool or process parameters are easily carried on the results and can quickly review the results.
Similarly, the cast uniformly fill be improved for better and more deeply rooted, to avoid porosity, porosity of the runners can be modified to reduce the levels of trapped air leads to this, the layout is internal coolingdeveloped to minimize the time of solidification and allow faster production cycles and simulations, calculations can include stress, life nut can be used for prediction, cracked castings or distortion. The continued use of MAGMASOFT (r) during the pouring and casting process development and create stable processes from the first study about the good die.
Further adjustments during the production of jets are small and should not changeCasting in the form or design in general. The result is a design for casting, the forms and process times and costs can be used until no longer needed jets significantly reduced design and production. The reduction of time and effort involved in the areas of design and production allows the team to improve time to better focus on other important tasks, Such as the impact of different steel die or heat treatment to extend Implementation life dieDevices to increase the more demanding the opportunity to cast complex castings or fusion energy savings, increase labor to bring automation and power – all without disturbing the production of a good race.
Transferred to these changes to increased competitiveness and strengthens the position of the sector in the global market.

To save more time and energy
The area can not be improved, that the human speed. computer work hundreds of times faster than they did years ago, but that is a transformation that people will never be able to duplicate. Unlike machines, however, people are intelligent and capable, with which hardware and software improvements to our advantage. fly Yes, always from the office, a meeting with a large dining and living in a beautiful hotel is great – but in many cases it is also inefficient and a waste of time and money. Today, with fast access to the Internet, the availability of industrial e-mail, FTP, telephone or web conferencing, and those technologies have found their way into the design process. Gone are the days when people had to drive hours for a brief meeting, or traveling abroad to visit foreign sources. This does not mean that the designer> The follow-up tool and should not know – But it was reduced at a time, an engineer on a lot and can be purchased worldwide, staff, 12:59 "The visit will be reduced or even eliminated.
With the increasingly short time frame allowed for the design, engineering, construction and implementation of a process of travel is not possible or not economical. This time is needed to work on the project. Each day thereafter, may affect the delivery date. Sending Hugedigital files on the Internet may take several hours, but once transferred, are immediately available for a web conference. Some companies, but they still face to face meetings, analyze the results, time and money for almost all participants. But the greatest loss of time is not even discussed. This is the hesitation in making decisions on the purchasing, ordering the project. Although the quotes from cast iron and tool vendors have been in a timelyThus companies are able to finance the political mandate to save a round, second or third citations in one study, a dollar here and there.
Although the total amount of time-to-market "very limited, more than half the time, can be taken in the selection so that it is much as four months, they have in the caster and tool-not enough time to a process of creation, mold design and deliver good projects. buyer hesitation, decided to be a source of cutsavailable in the engineering time and may face significant costs for the process, destroying the savings in short-term do with additional costs of production and delays in time for the market to add. As long as a group see only the costs, direct and not included the cost of all the casting, the project never achieved complete financial Their Potential for the company.
Summary
Streamlining the process of die-engineering can still save a lot of time and energyto save money as you can see. With current computer equipment and software, travel times and costs are reduced significantly, while communication can be done quickly and more effectively. Make faster decisions from renewable projects more time with the engineers, the development of stable processes that produce better. By focusing on the technologies available can protect their irreplaceable resources – time and energy – as more efficient, and mostImportant in this economy, more profitable.
