Gas-Assist Injection Molding

Gas-assist injection molding (GAIM), a process that uses an

inert gas to create one or more hollow channels within an injection-molded plastic part,

has been around for well over two decades. Used extensively to make products such as

appliance handles and furniture seat backs and frames, GAIM enables manufacturers to

cost-effectively make large struct  ural parts that cannot be produced by the standard

injection molding process.

Likewise, IXEF® polyarylamide compounds produced by Solvay Advanced

Polymers, L.L.C. have long been considered a reliable choice for applications requiring

high strength and stiffness. Because this material provides an excellent surface finish,

even at high glass loadings, it is particularly appealing for structural-type applications

where cosmetics are important.

Until recently, however, the process and the product had never teamed up—that is

until HYXPlastic Services of Broadview, Ill., a market leader in plastic injection

molding for both the major appliance and office furniture industries, decided to bring

them together.

“The coupling of the GAIM process with IXEF compounds has been very

successful,” said Wayne Moore, engineering manager of HYXPlastic Services. “When

you have a hollow piece with a large cross section, you need a material with a lot of

strength and stiffness, and good dimensional stability. IXEF compounds have that. Plus

they offer the added advantage of a durable high gloss surface finish.” 

“We’re very excited by this new opportunity for IXEF compounds,” said Chris

Scarazzo, market development manager for Solvay Advanced Polymers. “By using gas

Gas-assist injection molding, it is now possible to achieve metal-like part performance at a

fraction of the cost.”

For structural applications with high load-carrying requirements, traditional

materials include die cast aluminum, long and short glass-filled nylons, and bulk molding

compounds. According to Scarazzo, each of these materials have shortcomings: high cost

due to secondary operations for die cast aluminum, poor aesthetics and severe mechanical

property loss due to moisture absorption for glass-filled nylons, and high scrap rates for

bulk molding compounds.

According to Scarazzo, potential applications for the GAIM-IXEF resin duo

include office furniture applications, such as seat backs, seat frames, arm rests, and chair

bases, as well as handles, hinges, and knobs for major appliances, such as refrigerators

and dishwashers.

We offer below service

Injection Molding Solutions: HYX MOLD, is a fully service plastic mold and injection molding compay. Providing services from product inception and design- helping you get your ideas from informal to formal media. From there to tool building – making a precision mold of your product and completing the molding process. All the while, our top notch quality program will ensure the best finished product.

Injection Moulding: Injection moulding requires that plastic pellets be melted and then forced into the mould cavity. The plastification of the material in the barrel usually is facilitated by sheer and friction from a rotating screw that also feeds in new material. In thermoplastics the material is cooled in the mold until it can be ejected.

Fully AutomaticFully automatic molds run with no operator. They may utilize a variety of mechanical devices to facilitate part removal such as mold sweeps, air blasts or sprue pickers. They may contain core pulls, cams to remove undercuts, multiple plates, hot runner or insulated runner systems, unscrewing devices or any number of devices and techniques to improve efficiency.

Semi-automatic & Hand operated: Semi-automatic molds are typically mounted in the press and require an operator only to perform a specific operation of the cycle (i.e., remove a core, place an insert, remove the part from an undercut). Hand operated molds require an operator to physically remove the mold from the press and disassemble it to remove the molded part. They are used for very small quantities or parts that have undercuts, threads or other complicated features.

Prototype Tools: Prototype tools can produce thousands of parts and, if shrinkage is not a factor, a variety of materials can be tested. Modifying a prototype tool costs substantially less than the cost to change a production tool. Make your changes in this development phase, not after the parts go into production.

Compression Molding: Compression molding involves a heated mold in which the material charge is placed into the mold (often having been preheated) and the mold halves compress the material into shape.

Transfer Molding: Transfer molding is a process largely reserved for thermosets in which (much like the injection process) preheated material is transferred with a plunger into the closed mold cavity.

Pressure Forming: Pressure forming can refer to many materials and processes.

University professor Dr.-Ing. Christian Hopmann, now 42, will succeed Prof. Dr.-Ing. E.h. Walter Michaeli as head of the IKV(Institute of Plastics Processing), director of the Association of Sponsors of IKV and holder of the Chair of Plastic injection moulding Processing at RWTH Aachen University when the latter reaches retirement age next summer.

Hopmann studied mechanical engineering at RWTH Aachen University, with a particular focus on plastics processing, and received his doctorate in 2000. His study of ceramic injection moulding was in fact supervised by Prof. Michaeli. Hopmann was initially a research fellow at the IKV. Later, he headed its department of part design and materials technology. From 2001 to 2004, he was chief engineer and, in this capacity, also deputy director of the IKV. This background prepares him well for his future activities.

Between 2005 and late 2010, Hopmann worked in industry. At RKW AG Rheinische Kunststoffwerke (today, RKW SE), a leading European manufacturer of high-quality polyethylene and polypropylene films, nonwovens and nets, he served as head of quality management at RKW’s site in Petersaurach, Germany, and as chief of extrusion. Since the beginning of 2010, he had been managing director of RKW Sweden AB in Helsingborg.

Hopmann is looking forward to his new assignment at the IKV. “The special constellation of the institute, which is outstandingly networked not only in interdisciplinary research inside and outside RWTH but also in industrial joint research, is the basis for excellent academic teaching,” he says. “Caring for and expanding this is a major challenge and an honour which I am very pleased to accept.”

The IKV at RWTH Aachen University is a large research institute employing more than 300 people who work on problems encountered during the processing of many different types of plastic. It is divided into four specialist departments covering injection moulding and polyurethane technology, extrusion and further processing, part design and materials technology, and composites. The institute comprises the Centre for Analysis and Testing of Plastics, and a Training and Further Education department, as well. It is run by the Association of Sponsors, whose membership now consists of about 250 plastics companies from all over the world.

PLASTICS IN TRANSPORTATION

PLASTICS IN TRANSPORTATION

Progress in Motion

On land and on sea, in the air and in space – plastics are on the move. Durable, lightweight and corrosion resistant, plastics offer fuel savings, design flexibility and high performance at lower costs to designers facing today’s complex transportation needs. In automobiles, light trucks, trailers and motorcycles; in marine craft from canoes to minesweepers; in trains, buses and other mass-transit vehicles; in airplanes and space shuttles – everywhere, plastics are on the move. to make custom injection molding parts for transpotantion parts, you need plastic molds and find plastic molding company to cooperate with, this will be solution to support you.

On the Fast Track

During the oil crisis of the ’70s, automakers discovered that plastics make cars more energy efficient by reducing weight. With that discovery, plastics began finding their way into automobile components such as bumpers, fenders, doors, safety and rear-quarter windows, headlight and sideview mirror housings, trunk lids, hoods, grilles and wheel covers.

Auto makers choosecustom plastic injection molding parts for their durability, corrosion resistance, toughness, ease of coloring and finishing, resiliency and light weight. Plastics reduced the weight of the average passenger car built in 1988 by 145 pounds. That saves millions of gallons of gas each year and will save the energy equivalent of 21 million barrels of oil over the average lifetime of those cars. By the 1993 model year, over 250 pounds of plastics were used in the average vehicle.

Automobile designers also discovered that plastics solve one of their most complicated design problems: what to do with the fuel tank. Using plastic gives them the freedom to fit tanks into the overall concept rather than designing around the unwieldy but essential part.

Bus manufactureres, too, are turning to plastics for exterior and interior components to provide dimensional stability and impact resistance in long sections. Trains and buses use plastics in seating, window/door frames and other interior applications that require durability, cleanability and low maintenance. Subway commuters in many cities owe much of their comfort to plastics, sitting on plastic-foam seats with plastic seat covers, standing on polyester carpets and holding securely to plastic handles. The moldings, window casings and interior panels of subway cars are also plastic, and the windows are polycarbonate.

Modern over-the-road trucks owe much of their sleek design to plastics. The contoured cowls over the cabs reduce air resistance and improve fuel efficiency. Truck tanks made of advanced composites offer the same benefits.

On the Not-So-Fast Track

Bicycles (seats, handlebars, trim and accessories), motorcycles (helmets, seats, windshields and instrument panels), roller skates, skateboards, canoes, kayaks, skis and ski boots, surfboards, snowboards and advanced athletic shoes – when people move, plastics move with them.

Advanced composite kayaks, for example, powered the U.S. Olympic team to gold medals in Seoul. Composites help achieve the required shape with minimum weight and allow better weight distribution.

Making Waves

Plastics made a big splash in the nautical world when America’s Cup entries began using advanced composites in futuristic designs that set the boats soaring. Stars and Stripes ’88 took the Cup using composite materials originally created for aircraft, while New Zealand featured a 17-story-high mast made from advanced plastic materials. Both were harbingers of marine design undreamed of when 19th-century sailors first raced for the “Auld Mug.”

The real plastics revolution in boatbuilding began in the 1940s, when fiberglass hulls made their debut. Boats were sleeker, better looking, more fuel efficient, more maneuverable and easier to maintain. No more long weekends spent scraping and repainting. Plastics, marine designers learned, put the pleasure back into pleasure boating. Plastic Molding Manufacturing if not only for boating but more than transportation area, like auto, industrialetc

Today, boatbuilders looking for strength and lighter weight turn to plastics for sails, rudders, dagger boards, centerboards, slats, spars and wings, as well as hulls.

Cleared for Takeoff

The oil crisis of the ’70s taught the airline industry the same lesson it taught automakers: lightweight plastics save fuel. The oil crunch forced aerospace companies to design aircraft that used less fuel. Translated, that meant more efficient engines, improved aerodynamics and reduced aircraft weight. It also meant a role for plastics.

Today, jet engine manufacturers are increasing their use of plastic materials for the same basic reasons: reliability, efficiency, fuel savings and improved performance. In the interiors and functional parts of aircraft, plastics are meeting more and more design requirements, and as the needs increase, new plastic materials are being created to meet them. In aircraft design and production, plastics are used in the tooling process, cutting costs and enhancing flexibility.

All Systems “Go”

The air and space craft of the next century increasingly will be made of plastics. Commercial aircraft will soar with plastic wings and tails, and small composite planes will flourish.

The military will continue to depend on plastics to create even lighter aircraft with fewer parts and the ability to evade detection. The Stealth bomber, for example, uses composites of graphite-like substances mixed with resins to soak up radar energy and transform it to heat, rather than reflect it. (In a more down-to-earth application, the U.S. Army is using a composite heavy-assault bridge that spans 106 feet, supports 70 tons and folds.)

And plastics are expected to answer many of NASA’s calls for materials to create and perfect high-performance supersonic/hypersonic aircraft, nuclear space power systems and space stations. find a plastic mold from china mold company to solve your issues.
