What is K value in PVC?
K Value is an indicator of molecular weight : K-57 is medium for injection molding,K-67 is medium-high for rigid extrusion, K-70 is higher for plasticized extrusion or calendering. K value relates to other ASTM indicators of molecular weight like Intrinsic Viscosity or Inherent Viscosity.
What are the most efficient engines?
The most efficient engines are typically those that maximize energy conversion and minimize waste. Diesel engines, especially turbocharged and direct-injection variants, often exhibit high thermal efficiency due to their higher compression ratios. Additionally, gas turbine engines, used in jet propulsion, are designed for high efficiency at specific operating conditions. Electric motors are also highly efficient, converting over 90% of electrical energy into mechanical energy with minimal losses.
What products makes compression molding?
Compression molding starts by inserting plastic or gelatin into a heated mold. Once the material is heated to a pliable state, a hydraulic press compresses the pliable plastic against the mold, which creates a perfectly molded piece. This process is used mostly for manufacturing gears, dinnerwear and electrical parts.
Why are wind turbines so high?
To get the maximum amount of wind. If they were low to the ground the wind levels would not be so high.

Where can I get advice on plastic injection mold?
Luckily, plastic injection molding is a very common technique and there is a plethora of information regarding the subject on the internet. Often, the most information can be found on blogs regarding machinery and molding, and Wikipedia is usually a high-visited source.
How does Protomold injection molding work?
Protomold injection molding works by forcing engineer grade resin under high pressure into a cavity that is created through milling advanced aluminum alloys. This is a highly specialized and computer managed process that is cutting edge technology.
How do I use injection molding?
The injection molding process requires the usage of an injection molding machine, raw plastic material, and a shape. The plastic is liquefied inside the injection molding machine at that point injected into the shape, where it cools and solidifies into the definitive part.
What are the important stages of the injection molding process?
The injection molding process of plastic parts mainly includes 4 stages: Filling, holding, pressure, cooling, demolding These 4 stages directly determine the molding quality of the product, and these 4 stages are a complete continuous injection process. Filling stage The filling is the first step in the entire process injection molding cycle, from the time the mold closes to the start of injection molding until the mold cavity is filled to about 95%. In theory, the shorter the filling time, the higher the molding efficiency, but in practice, the molding time or injection speed is restricted by many conditions. High-speed filling When filling at high speed, the shear rate is high, and the viscosity of the molten plastic decreases due to the effect of shear thinning, which reduces the overall flow resistance; the local viscous heating effect will also make the thickness of the solidified layer thinner. Therefore, during the flow control phase, the filling behavior often depends on the volume to be filled. That is to say, in the flow control stage, due to the high-speed filling, the shear thinning effect of the melt is often great, but the cooling effect of the thin wall is not obvious, so the effect of the rate prevails.
What is injection molding?
Injection molding is a commonly used manufacturing process for the fabrication of plastic parts. the injection molding process need injection mold and injection machine.--------------------------------------------------------Injection molding is a manufacturing process for producing parts from both thermoplastic and thermosetting plastic materials. Material is fed into a heated barrel, mixed, and forced into a mold cavity where it cools and hardens to the configuration of the mold cavity.After a product is designed, usually by an industrial designer or an engineer, molds are made by a moldmaker (or toolmaker) from metal, usually either steel or aluminium, and precision-machined to form the features of the desired part. Injection molding is widely used for manufacturing a variety of parts, from the smallest component to entire body panels of cars.the following is a photo of the injection molding process:http://www.vulcanmold.com/article/Plastic-Injection-molding-process.htmlA Hollow mould is made from steel in several parts. when the mould is all together the hollow within it is the same shape as the object you wish to produce. The mould is water cooled to keep its temperature under control. molten plastic is forced into the mold at high pressure. it is left to cool for a specified period of time, then the mold is pulled apart in such a way that the object falls out of the mould and the whole thing starts all over.
What are the disadvantages of injection molding?
*High set up costs - Moulds etc *Complicated process *can only be used for large quantities due to costs

How can I make a hard plastic mold?
To make a hard plastic mold, you can use a process called injection molding. This involves melting plastic pellets and injecting them into a mold cavity, where they cool and harden to form the desired shape. The mold can be made from metal or other materials that can withstand the high temperatures and pressures involved in the injection molding process.
Understanding Injection Molding?
When it comes to manufacturing high volumes of plastic parts or components, few processes are more efficient or effective than injection molding. Since being developed in the 1930s, injection molding has become one of the most popular methods of creating plastic parts and pieces. The process, which was inspired by the metal die casting techniques, brings many benefits to the table. By understanding how it works, you can get a clearer idea for why it is so enduringly popular.The Injection Molding ProcessThe injection molding process begins with the injection of small resin pellets into an injection molding machine. The machine is made up of two primary components - a clamping unit and an injection unit. Before the process starts, a mold is created that will be used to form the plastic part that is needed. Once the mold has been clamped closed with high pressure, the resin pellets are put into the machine. Colorants are put in along with them, to give the resulting part the appropriate color.When they are placed in the injection molding machine, the resin pellets fall into its injection unit. The unit is heated up and the resin pellets are melted. The resulting molten plastic material is then injected into the mold, or clamping unit. This is achieved through the use of ramming devices or screws.At this point in the injection molding process, mechanical or hydraulic pressure is applied to the molten plastic. This is done in order to ensure that every corner of the cavity is filled, so that there are no deformities in the completed part. Following this point, the plastic is allowed to cool. The two halves of the clamping unit are eventually opened and the completed part is ejected with ejecting pins. Any extra pieces, or runners, are trimmed away and recycled.The Top Benefits of Injection MoldingInjection molding is popular for many reasons. Finishing requirements are minimal; when a piece is complete, little else usually needs to be done to make it usable. Injection molding is also very efficient. The process doesn't generate a lot of waste, since the little scrap that is produced is usually remelted or otherwise recycled. For manufacturers, these benefits translate into savings; in turn, a company's bottom line can be greatly improved. Considering the fact that one injection molding machine - and one mold - can create thousands of identical parts, it's easy to see why the process is so well regarded.
