University of Massachusetts Amherst Paul J. Dauenhauer led research team found that the new method, a production of biomass plastic, low-cost, most of the biomass as a raw material can be to 75% the yield of xylene (biomass plastic raw materials), the study results were published in the journal of the American Chemical Society (ACS), the “catalyst”. Xylene was used to produce PET (polyethylene terephthalate) plastic, the scope of uses including many products, such as carbonated beverage bottles, food packaging, synthetic clothing, and even auto parts. At present, the plastics industry is the oil as raw material to produce para-xylene; new method is a renewable way of biomass raw materials of the chemical, thereby producing marked with the triangular recycling logo “1 #” plastic products. This method uses molecular sieve catalyst, through the three-step reaction can be conversion of glucose to para-xylene in the high-temperature bioreactor. Nano-structure of the catalyst has a great effect on the biological response, the catalyst of this particular design is the key to success, it has been a series of optimization improvements, used to promote the reaction of p-xylene, and improve yield. This is a major breakthrough, because the other method for the production of renewable xylene, or expensive (eg fermentation), or low reaction efficiency, low production yield. In the future, the method can be further optimized to improve the yield of para-xylene and reduce costs. This finding is part of the innovative energy catalytic center (CCEI), a breakthrough research to the manufacture of biofuels and chemicals from lignocellulosic biomass program

How China mould maler calculator the mold price

Chinese Mold prices—-china mould factory calculator way

An empirical calculation methodMold Price = material cost + design fees + fees and profit + VAT + test mold fee + packing and shipping feeThe ratio is usually as follows:The cost of materials: materials and standard parts accounted for 15% of the total cost of the mold to 30%;Processing fees and profits: 30% -50%;Design Fee: 10% of the total cost of the mold to 15%;Tryout: large and medium-sized mold can be controlled within 3%, and small precision molds is controlled within 5%;Packaging and transportation costs: according to the actual calculation or of 3%;VAT: 17%(2) the material coefficient methodThe mold material cost can be calculated according to the mold size and material prices.Mold price = (6 ~ 10) * Material feeForging dies, plastic mold = 6 * The cost of materialsDie-casting mold = 10 * materials feeMold quotation estimatesA first look at customer requirements, calling for a decision on the choice of materials and heat treatment.2, select the good material, and a rough mold program map, from which to calculate the weight of the mold (to calculate the price of the mold core material and the mold material) and heat treatment costs. (Rough weight)3, the processing costs, according to the complexity of the mold core, general processing costs and the mold core material prices from 1.5 to 3:1, the processing cost of the mold is generally 1:1.4, the risk premium is 10% of the total amount above.5, tax6, the design fee is 10% of the total amount of the mold.Bidding strategies and settlement of the moldThe purchase and settlement of the mold is a continuation of the mold valuation results. From the valuation of the mold to mold the offer, only the first step, the ultimate goal of the mold through the mold manufacturing after the delivery of settlement, the formation of the final settlement price of the mold. In this process, people always want the valuation of mold = mold price = mold settlement price. In practice, the four price is not exactly equal, there may be fluctuations in error. This is to be discussed below. When the valuation of the mold, the need for proper handling, finishing into a mold quotation, signed mold contract basis. Through repeated negotiations to discuss the final form of the mold price, both sides recognized the signing of the contract. To officially start the processing of the mold.A mold valuation and offer quotations and molds price After the valuation of the mold, and can not immediately directly as a quotation. In general, we must conduct a comprehensive analysis based on market conditions, customer psychology, competitors, status and other factors, the collation of appropriate valuation, an increase of 10-30% the first offer on the basis of valuation. Bargaining, can be reduced according to the actual offer. However, when the mold to discuss the offer of 10% below the valuation, the need to re-mold improve and refine the estimates, in Guaranteed favorable circumstances, the signing of the mold processing contract to finalize the mold price. Mold price has been accepted by both sides and signed the contract priceAt this time the formation of mold price may be higher than the valuation or lower than the valuation. Mold price is lower than the discussions of mold in this price into the need to re-propose amendments to mold requirements, conditions, and programs to reduce some of the requirements may reduce the cost of the mold, signed mold-price contract, and then re-estimate the It should be noted that the mold belong to a higher technological content of the specific products should not be cheap, even at a loss to meet the customers. But should be good quality and inexpensive, to ensure mold quality, accuracy, life the first place, rather than the price of the mold a little too seriously, they are liable to be misleading action. Pursuit of mold cheap, it is difficult to guarantee the quality, accuracy, life of the mold. Cheap is not generally die industry for. However, when the mold manufacturing and product development and production of the same accounting unit, or economic interest, in this case, the purchase of the mold should be its cost price as a quotation. The valuation of the mold only to estimate the basic cost of part of the mold, and other costs, profit not to consider, be the profit of the products produced after extraction of the added value of the mold fee as compensation. But at this time offer can not be used as the price of the mold, only as a mold pre-development costs. The future, once the products successfully developed to generate profits, you should extract the added value of the mold fee, returned to the mold manufacturing units, two together, to form the price of the mold. At this time the formation of mold price may be higher than the price of the first case, the mold, and even high rates of return, which is several times of the normal mold price, ranging from several hundred times. Of course, there are the possible rate of return equal to zero. Second, the regions of the mold price and time differential Here should also be noted that the valuation and price of the mold in various enterprises, various regional, national; at different times, different environment, its meaning is different, that is, there are regional differences and the time difference. Why would the price difference, this is because: the one hand, enterprises, regional, national mold manufacturing conditions are not the same, equipment, technology, technology, personnel concepts, consumer standards in all aspects of the different, resulting in the cost of the mold, profit targets, estimates vary, resulting in a different mold price difference. Generally more developed areas, or high technology, and equipment into the more advanced, more standardized, large-scale mold enterprise, their goal is high quality and high prices, while in some areas with low level of consumption, or low-tech, equipment and less on small and medium-sized mold enterprise, the relative mold prices estimated to be lower. On the other hand, the mold price there is still time difference, namely, aging poor. Different times, resulting in a different mold price. This limitation difference has two aspects: First, a pair of mold have different prices at different times; two different mold manufacturing cycle, and its price is also different.
