nal standards. Vacuum drying how to improve profit margins? Although the resin dryer is usually referred to as auxiliary equipment, but the decision of its type selection there may be a plastics processing, play a leading role in business strategy. This is in Belgium (the whole family), it is such, is a global crossindustry manufacturers, business focus involving electronic and electrical (E amp。 E) equipment, ponents for injection molding. By abandoning the traditional hot air dryers in favor of the principle based on a new type of vacuum drying equipment (Figure 1), pleted its Hasselt in Belgium (Hasselt) plant simplifies the injection molding process to obtain a substantial savings and improve product quality. As with other electronic and electrical (E amp。 E) equipment supplier, as the three strategic challenges facing: 1) intense price petition caused by the supplier relentless pressure to cut costs, improve production efficiency。 2) customers on product quality and balance the demanding requirements。 3) the longterm energy costs will be high expectations. Vacuum Drying of the most obvious benefits related to the third challenge: with similar specifications, hot air dryer (Figure 2) pared to pletely dry resin in the vacuum dryer can save 80% of the energy. However, due to the pletion of the original, while only onesixth of the time, the use of vacuum dryer will have the opportunity to significantly improve production efficiency. The short term, this can be started on Monday morning ahead of manufacturers in the production of cold start time。 in the long run, it can provide a more streamlined operational convenience to concentrate. Finally, Vacuum Dryer provide shorter residence time and higher efficiency to reduce drying defects and lower reject rate. Used in the factory in Hasselt 40 molding machines, 26 table is used for injection molding polyamide material to be made into models of AA and AAA batteries small security cover. The use of 12 hot air dryer to dry 26 resin molding machine. By using the three USKui? LPTM vacuum dryer replaced (fourth sets new LPD vacuum dryer for emergency standby), according to the Technical Manager, Mr. Rudi Vermeulen stated that achieved the following results: Energy cost savings. 92% reduction of energy consumption, saving 15,700 euros. The corresponding cost savings estimate does not include the power sector, Mr. Vermeulen the additional peak imposed a fine of 5,000 euros, not including the estimated Mr Vermeulen great to exclude from the factory for the production of heat hot air drying machine electricity consumed by airconditioning energy savings. Production longer. Cold start by reducing the time Monday morning, received an additional 192 hours per year at full capacity production time. According to Mr. Vermeulen rough estimate, assuming that sales levels will be sufficient to maintain the plant at full capacity, this new production capacity can bring an extra 57,600 euros per year could be the amount of sales of products. Streamlining and automation. While hot air drying machine 12 in any one able to meet not more than 2 sets of injection molding machines for production capacity requirements, vacuum dryer drying cycle, shorter and this makes it possible to cover the 26 battery production lines converted to a PLC control central delivery system. Hot air dryers from 12 to 3 units (actual use) vacuum dryer conversion brought 2,970 euros, or 92% of the preventive maintenance savings. Bulk container bags package from the package to 11,800 euros per year cost savings. Defect rate / scrap rate. According to Mr. Vermeulen stated, as to avoid excessive drying, and the output of the resin contained in the residual moisture than hot air dryers are less resin processing, vacuum dryer significantly reduces the rejection rate. Mr. Vermeulen said, from waste reduction, airconditioning costs and production efficiency savings arising from the specific data yet to be statistics, this is due to the recently installed a vacuum dryer and the central feeding system. Calculated over the current annual statistical data and other cost savings reached 35,470 euros. These savings, bined with the increase in annual output of 57,600 euros, for a total of 93,070 euros. Because the central feeding system, and 4 sets of vacuum dryer total investment cost of 100,000 euros, the overall total cost savings sufficient to manufacturers in the number of little more than a year to recover the investment cost. If you wait until the other end and then save the data to collate statistics, including the actual cost recovery will take less than one year. New injection molding machines to speed up drying operation starts The vacuum dryer energy consumption and only a very short time a number of resins can be ready to prepare for processing, which is due to their design and operation of the standard hot air / desiccant dryer is different in two ways: Vacuum dryer using a vacuum to reduce the boiling point of water so quickly into wet vapor, the water vapor really is removed from the resin particles, and not covered with dry air and then slowly remove the resin particles in which the moisture. Vacuum Dryer mark in three separate locations simultaneously heating and vacuum drying, to small batch production, which will actually batch process into a continuous process, so that the output and processing machines to keep pace . Vacuum Drying small quantities of batch output and a short drying cycle allows only 40 minutes to prepare adequately for the drying of the resin molding machine feeding, rather than the traditional use of the dryer they needed 4 hours. This is why the start time on Monday to reduce their reasons. Hasselt casting plant in order to secure the ba。
