Polymer Insulator Resists Thousands of Volts

Polymer insulators are made from resins, a relatively uncommon material for insulator compared with porcelain. With high electrical resistance, it can moderate the voltage for stable operation. Polymer insulator being a common product applied in electronic device, it can moderate the voltage for stable operation with high electrical resistance.

 

An electrical insulator is a material whose internal electric charges do not flow freely, and which therefore does not conduct an electric current, under the influence of an electric field. A perfect insulator does not exist, but some materials such as glass, paper and Teflon, which have high resistivity, are very good electrical insulators. A much larger class of materials, even though they may have lower bulk resistivity, are still good enough to insulate electrical wiring and cables. Examples include rubber-like polymers and most plastics. Such materials can serve as practical and safe insulators for low to moderate voltages (hundreds, or even thousands, of volts).

The Process and Function about Ultrasonic Welding Machine

       For joining complex injection molded thermoplastic parts, ultrasonic welding machine can be easily customized to fit the exact specifications of the parts being welded. The parts are sandwiched between a fixed shaped nest and a sonotrode (horn) connected to a transducer, and a ~20 kHz low-amplitude acoustic vibration is emitted.. When welding plastics, the interface of the two parts is specially designed to concentrate the melting process. One of the materials usually has a spiked energy director which contacts the second plastic part. The ultrasonic energy melts the point contact between the parts, creating a joint. This process is a good automated alternative to glue, screws or snap-fit designs. It is typically used with small parts such as cell phones, consumer electronics, disposable medical tools, toys, etc., but it can be used on parts as large as a small automotive instrument cluster.

       Ultrasonic welding can be used for both hard and soft plastics, such as semicrystalline plastics, and metals. Ultrasonic welding machine also has much more power now. The understanding of ultrasonic welding has increased with research and testing. The invention of more sophisticated and inexpensive equipment and increased demand for plastic and electronic components has led to a growing knowledge of the fundamental process. Scientists from the Institute of Materials Science and Engineering (WKK) of University of Kaiserslautern, with the support from the German Research Foundation, have succeeded in proving that using ultrasonic welding processes can lead to highly durable bonds between light metals and Carbon-fiber-reinforced polymer (CFRP) sheets.

How to Use Ultrasonic Welder to Assemble Thermoplastics?

       Ultrasonic plastic welding is the joining or reforming of thermoplastics through the use of heat generated from high-frequency mechanical motion. It is accomplished by converting high-frequency electrical energy into high-frequency mechanical motion. That mechanical motion, along with applied force, creates frictional heat at the plastic components' mating surfaces (joint area) so the plastic material will melt and form a molecular bond between the parts. Plastics assembly is a fast, clean, efficient, and repeatable process that consumes very little energy. No solvents, adhesives, mechanical fasteners, or other consumables are required, and finished assemblies are strong and clean.

       Using ultrasonic welder has many advantages over traditional methods. For one, welding occurs at low temperatures relative to other methods. So, the manufacturer does not need to expend vast amounts of fuel or other energy to reach high temperatures. This makes the process cheaper. It's also faster and safer. The process occurs in fractions of a second to seconds. So, it can be done more quickly than other methods. Ultrasonic welding does not require flammable fuels and open flames, so compared to other welding methods, it's a safer process. Workers are not exposed to flammable gases or noxious solvents. Finally, ultrasonic welds are as strong and durable as conventional welds of the same materials. Ultrasonic welding can be used to bond the metal in less time and at lower temperatures than traditional welding.

How to get your ideal molded plastic design?

Plastic injection molding is a process that involving the use of plastic.  With the granular polymer which is fed into a heated barrel, the rotation process of a screw type plunger is therefore generated by the friction between polymer granules while the screw is rotating.  Nowadays, one of the most popular techniques on plastic injection is called double injection.  This common technique contains several of factors to influence the quality of the molded plastic product.  In this way, the selection of a plastic injection manufacturer for your molded design is crucial. 

Start with material melting process, the melted plastic is forced into a mold cavity with the required shape through a nozzle.  The action is finished by the screw rotation action, and then the mold is waited to be cold, sometimes you will need cooling channels to run through it.  After the cooling, the molten plastic will be solidified while the mold cavity is filled.  The whole double injection process is simple, and with the fact that the plastic is not expensive, it can be manipulated into any shape.  So you can prepare more extra shape in hand to handle any failure during the manufacturing.

In the process of becoming pretty by cosmetic, firstly, women need to choose the quality cosmetics. Then, they have to know how to apply cosmetic wisely to fit for their skin condition and shape.

       For the first step, the key factors to determine whether the cosmetic products are with high quality not only lie on the quality of cosmetic ingredients, but count on the cosmetic bottles as well. Nowadays, airless packaging continues to show up in all areas of skin care, including natural and organic products, mass-market and prestige facial products, and even body care products. It is said to be the most sanitary way to reserve cosmetics.

       Among the various cosmetic and skin care products, airless packages are especially well suited to highly viscous skin care products for the body, such as body butters. The airless cosmetic bottles may also help maintain decorative product fills. One popular fill design is a swirl. Airless technology can help a product’s swirl design maintain its form as product is being dispensed.

The Usage of Polycarbonate Sheet

       From the thin plastic lenses found in UV-protective sunglasses, to the thick, bulletproof windows used in security vehicles, polycarbonate sheet plays an important role in safety and environmental protection. Polycarbonate is a versatile, tough plastic used for a variety of applications, from bulletproof windows to compact disks (CDs). The main advantage of polycarbonate over other types of plastic is unbeatable strength combined with light weight. Bulletproof windows and enclosures as seen inside banks or at drive-throughs are often made of polycarbonate.

       Polycarbonate sheet is moldable, durable, lightweight, flame resistant, shatterproof, and energy efficient. What’s more import, it is high-impact resistance, which can be more than 200 times greater than tempered glass. With the stronger features, polycarbonate is usable in a wider temperature range and more expensive. For another thing, highly transparent to visible light and has better light transmission characteristics than many kinds of glass are one important features.

       Unlike most thermoplastics, polycarbonate can undergo large plastic deformations without cracking or breaking. As a result, it can be processed and formed at room temperature using sheet metal techniques, such as forming bends on a brake. Ridged sheets of polycarbonate are often installed over walkways, patios and terraces to filter and reduce ultraviolet sunlight, as well as provide rain and snow protection. Polycarbonate sheets are also used in fencing, providing a secure barrier that is practically indestructible.

The Applications for Double Injection Mold

       Compare to single injection mold, double injection mold is a more complex type of molding process. Furthermore, the cost of double injection mold is higher than single injection mold. Single and double injection molding using a single molding machine is made possible by providing two injection units, each having an injection nozzle, and a stationary platen three insertion holes into which the nozzles can fit. For double injection, the injection units are moved transversely of the stationary platen so as to orient both injection nozzles with a respective one of the insertion holes. On the other hand, the injection units for single injection are moved transversely of the stationary platen so as to orient one of the injection nozzles with one of the insertion holes, with the other nozzle not being so oriented.  

       The technique of double injection is widely used in many areas. For example, the telephone buttons use plastic of original color and PMP plastic for double injection in order to be pervious to light and to prevent finish from flaking off. So the double injection mold products can be applied to the following categories. Firstly, consumer goods such as, electric shavers, pen shells, spectacle frames, shells of phone’s push –button, bottle caps, and etc are the most common application. Secondly, double injection is suitable for spare parts for car like car lampshades, plastic steering wheels, acoustics sound, knobs, and handles, etc. What’s more, it’s applicable for such medical equipments as thermometer and ear thermometer. Finally, for electronic 3C industry, cell phones, mp3, mp4, game machines, and earphones use the technique of double injection frequently. 

The Composites and Application of Industrial Plastic Tooling

       There are different materials and design features are used in plastic tooling depending on the type of part that is being produced. Most molds (tools) are made out of steel or aluminum. Additionally, part design may require side actions in order to mold cores that are often perpendicular to the normal draw of the mold. These actions may be cam or hydraulically actuated.

       Epoxy systems are used in industrial tooling applications to produce molds, master models, laminates, castings, fixtures, and other industrial production aids. This "plastic tooling" replaces metal, wood and other traditional materials, and generally improves the efficiency and either lowers the overall cost or shortens the lead-time for many industrial processes. Epoxies are also used in producing fiber-reinforced or composite parts. They are more expensive than polyester resins and vinyl ester resins, but usually produce stronger and more temperature-resistant composite parts.

       Injection molding is used to create many things such as wire spools, packaging, bottle caps, automotive dashboards, pocket combs, some musical instruments (and parts of them), one-piece chairs and small tables, storage containers, mechanical parts (including gears), and most other plastic products available today. Take LCD cabinet for instance, since the requirements of LCD cabinet keep growing due to the development of technology, it becomes one of the popular applications for plastic tooling.
