ABS Acrylonitrile butadiene styrene (chemical formula (C8H8)x· (C4H6)y·(C3H3N)z) is a common thermoplastic. Its glass transition temperature is approximately 105 °C (221 °F). ABS is amorphous and therefore has no true melting point. ABS is a terpolymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene. The proportions can vary from 15 to 35% acrylonitrile, 5 to 30% butadiene and 40 to 60% styrene. The result is a long chain of polybutadiene criss-crossed with shorter chains of poly styrene-co-acrylonitrile. The nitrile groups from neighboring chains, being polar, attract each other and bind the chains together, making ABS stronger than pure polystyrene. The styrene gives the plastic a shiny, impervious surface. The butadiene, a rubbery substance, provides resilience even at low temperatures.
A term for several of kinds of pre developed plastic product packaging made use of for durable goods, meals, and for pharmaceuticals. The main element of a blister pack is a cavity or pocket made from a formable web, often a thermoformed plastic. This generally has a support of paperboard or a lidding seal of light weight aluminum foil or plastic. A sore that folds up into itself is typically called a clamshell. Blister packs serve for securing the products against the exterior elements such as moisture and contamination for extensive time frames. Opaque blister packs additionally secure delicate products against sun light.
A clamshell is a one-piece container including 2 halves signed up with by a hinge location which permits the property to come together to close. Clamshells are frequently made from a shaped plastic product, in a manner that resembles a blister pack. The name of the clamshell is drowned from the shell of a clam, which it looks like both in kind and function. Clamshell containers can be made from a range of plastics such as polystyrene, polyester, PVC, foam sheets, and so on. The product is by made by thermoforming mold into the shapes requested by the client. A single piece of product is made use of for the top and bottom with a living hinge that is indispensable with the product, instead of included independently. Clamshell Packaging can make use of a range of ways of sealing or closing. Some have self-locking tabs, snaps, or have a rubbing fit. Others utilize adhesive, pressure-sensitive tape, labels, staples, or are heat sealed.
Custom Thermoforming: is a process where plastic sheet is heated and shaped to a custom designed mold using vacuum and pressure assistance. Thereafter, the process of custom thermoforming involves the molded plastic parts being cut, trimmed and assembled into packaging designed specifically for your needs.
Electronic Packaging: A major discipline within the field of electronic engineering, and includes a wide variety of technologies. It refers to enclosures and protective features built into the product itself, and not to shipping containers. It applies both to end products and to components.
Draping the heated plastic sheet over a mold. Many heavy-gauge forming applications se vacuum only in the form process, although some use two halves of mating form tooling and include air pressure to help form. Aircraft windscreens and machine gun turret windows spurred the advance of Heavy Gauge Thermoforming technology during WWII. Heavy gauge parts are used as cosmetic surfaces on permanent structures such as kiosks, automobiles, trucks, medical equipment, material handling equipment, refrigerators, spas, and shower enclosures, and electrical and electronic equipment. Unlike most thin-gauge thermoformed parts, heavy-gauge parts are often hand worked after forming for trimming to final shape or for additional drilling, cutting, or finishing, depending on the product.
Integrated Circuit Packaging: In electronics manufacturing, integrated circuit packaging is the final stage of semiconductor device fabrication, in which the tiny block of semiconducting material is encased in a supporting case that prevents physical damage and corrosion. The case, known as a package, supports the electrical contacts which connect the device to a circuit board.
ISO 9001 2008 Registered with Design: is a family of standards for quality management systems. ISO 9001 2008 Registered with Design is maintained by ISO, the International Organization for Standardization and is administered by accreditation and certification bodies. The rules are updated, as the requirements motivate changes over time.
Light Gauge Thermoforming: Light Gauge Thermoforming are dominated by rigid or semi-rigid disposable packaging. Sheet thicknesses greater than 0.120 inches is usually delivered to the forming machine by hand or an auto-feed method already cut to final dimensions
Modified Atmosphere: The practice of modifying the composition of the internal atmosphere of a package commonly food packages, drugs, etc. in order to improve the shelf life.
Packaging: Technology of enclosing or protecting products for distribution, storage, sale, and use. Packaging also refers to the process of design, evaluation, and production of packages. Packaging can be described as a coordinated system of preparing goods for transport, warehousing, logistics, sale, and end use. Packaging contains, protects, preserves, transports, informs, and sells. In many countries it is fully integrated into government, business, institutional, industrial, and personal use.
Polylactic Acid: Polylactic acid or polylactide (PLA) is a thermoplastic aliphatic polyester derived from renewable resources, such as corn starch (in the United States), tapioca roots, chips or starch (mostly in Asia), or sugarcane (in the rest of the world). In 2010, PLA was the second most important bioplastic of the world in regard to consumption volume. The name “polylactic acid” does not comply with IUPAC standard nomenclature, and is potentially ambiguous or confusing, because PLA is not a polyacid (polyelectrolyte), but rather a polyester.
Polystyrene: Synthetic aromatic polymer made from the monomer styrene, a liquid petrochemical. Polystyrene can be rigid or foamed. General purpose polystyrene is clear, hard and brittle. It is a very inexpensive resin per unit weight. It is a rather poor barrier to oxygen and water vapor and has a relatively low melting point. Polystyrene is one of the most widely used plastics, the scale of its production being several billion kilograms per year. Polystyrene can be naturally transparent, but can be colored with colorants. Uses include protective packaging, such as clamshells packaging, lids, bottles, trays, tumblers, and disposable cutlery.
Thermoforming: A production procedure where a plastic slab is warmed to a flexible developing temperature level, developed to a particular form in a mold and mildew, and cut to produce an useful item. The slab, or “movie” when describing thinner assesses and particular product kinds, is warmed in a stove to a high-enough temperature level that it can be extended into or into a mold and mildew and cooled down to a completed form.
Our simplified version of thermoforming, whereby a sheet of plastic is heated to a forming temperature, stretched onto a convex, or into a concave, single-surface mold, and forced against the mold by a vacuum (suction of air). The vacuum forming process can be used to make most product packaging and speaker casings. Maryland Thermoform fabricates defense components, aircraft components, unmanned systems and thermoformed plastic enclosures.
