First, what is PET? PET （Polyethylene terephthalate） is one kind of polyester Is the abbreviation of English PolyethyleneTerephthalate Characteristics of PET raw materials * Excellent transparency of over 90%, excellent surface gloss and a glassy appearance. * Excellent fragrance retention and good air tightness. * Excellent chemical resistance, with acid as the head is almost resistant to all organic drugs. * Good hygiene, PDA – recognized by the largest chemical laboratory in the United States. * No toxic gases will occur when burning. * Excellent strength properties, and can be further improved by biaxial stretching. * The most complete PET preform quality defect solution in history Second, why should the PET material be dried before the production of the preform? A. Remove moisture from PET Because PET has a certain water absorption, it absorbs a lot of water during transportation, storage and use. High levels of water are exacerbated in production: – AA (Acetaldehyde) an increase in acetaldehyde. The odor of the beverage bottle causes the beverage to taste (but has little effect on the human body) – IV (Intrinsic Viscosity) viscosity drop. It has an

It is useful for the treatment of the rock matrix. Injection Pressure enables test fluids to be injected into rock formations without causing breakdowns or fractures. However, it requires surface pump pressure to achieve injection. The hydrostatic pressure of the liquid also affects the pressure injection as it contributes to the downhole pressure value. Injection Pressure is demonstrated in terms of PSI. Petropedia explains Injection Pressure Injection Pressure is used in injection molding machines. As the plastic materials that are used in the devices are quite stiff, they need injection pressure to fill the mold. It is one of the essential factors that are used to determine the properties of molded parts in the machine. The pressure should be high so that it can fill the molten polymer into the mold completely. It is further categorized into two parts, i.e., fill pressure and hold pressure. Fill pressure is stronger as compared to hold pressure. Setting Tips: 1. It

Below are some rules to select a right plastic injection moulding machine for your study and reference: 1. Choose the Right Model Series There are many dedicated injection molding machines available in the market. Most injection molding machines manufacturer developed different series molder for a dedicated industry. The first step is to pick up the right series machines according to your exactly product and it`s raw materials. For example, you should choose the PET Series or HPET Series injection molding machine if you want to produce PET preforms for PET bottle. 2. Can Load the Mould The second step is make sure the mould must can be loaded in the plastic injection moulding machine. Check the mould`s size, select a machine which guide post distance is bigger than the mould size. And double check the max. and min mould thickness, platen size to double confirm that machine can load your mould. This base on your already have a available mould. 3. Products Can Be Take Out Check the ejector stroke

So what were the top plastic products manufacturing trends in the year 2016? Here we listed a few trends for the plastic products manufacturing industry: Trend 1. Lightweighting – Not Just for Auto industry but other industries as well As we know that the auto industry has embraced light-weighting from heavy metals to plastic for many year. It will continue to influence how other products are manufactured. Product designers and engineers with work together with molders and resins suppliers for a product`s special needs. And replace the metal parts in small the then the large ones. These new lightweight materials tested in automobile will be used to migrate into other products that require durability. Like helmets and boots and other sports equipment. The construction industry has long embraced plastics and this trend will continue. New plastic building components will come on the market for buildings, bridges, and railroads to replace wood, steel and concrete. Trend

C-mold for plastic mold simulation analysis software was the best one but annexed because a mistake made by an engineer. From this video we can learn that Taiwan and China start the research of plastic molding and CAE technology in a very early date. And it still keep developing very fast up to now. We can see lots of new technologies in China in every month! I will keep an eye on this and post lots of new post focus on the plastic moldings and the CAE technologies. Tips: The new documentary film is start rolling this month! I will update this post as soon as I get the new record.

Two plate injection molding machine is compact and energy efficient, and it`s widely used in different industries. Two plate clamping mechanism has become the mainstream clamping construction for medium and large injection molding machines. What is the Top Plastic Injection Molding Machines Trends for 2016? Many Chinese enterprises focus on the development of two-plate injection molding machines in recent years. What is the highlights and future trends? Trend 1: Bigger tonnage Two-plate injection molding machine was developed on machines that tonnage is over 1000 ton (clamping force is over 10000KN) and in order to save the plant area. Now two-plate injection molding machines is became more and more common due it can save much rooms. Fast mold close is the biggest advantage of the traditional three-plate toggle injection molding machines, but needs larger plant areas. With years of development, the two platen machine`s is getting much fast than before and it`s faster the three platen ones. And it`s precision is better.
Read more →As a recent business census, there are many dedicated injection molding machines manufacturers in China. So how to choose the right partner always takes time and careful consideration. Here are some general considerations that you should keep in mind when starting this process: A Good Fit Mostly your needs are specialized and unique.
