Acrylonitrile Butadiene Styrene, ABS plastic, is an amorphous engineering thermoplastic whose main features are impact resistance, rigidity, high gloss, and low cost compared to other engineering resins. ABS resins are used in a variety of applications including automotive, appliances, construction, electronics, and business machinery. ABS is a terpolymer formed by the polymerization of acrylonitrile and […]
40% Glass/Mineral Nylon is a composite material made by combining nylon resin with glass mineral fibers. This material has several benefits that make it a popular choice. AGS calls this material FPA6240-200 and uses it in a variety of applications. Firstly, 40% Glass Mineral Nylon offers excellent strength and stiffness. The added glass mineral fibers […]
Direct injection molding of Injectoblend™ formulated regrind requires several modifications to the injection molding machine. Nozzle filters are essential components for injection molding with recycled plastics. Nozzle filters help to remove contaminants, such as...
Original Equipment Manufacturers (OEMs) are under increasing pressure to reconsider the use, reuse, and recyclability of plastic in their product. We have seen almost every OEM make policy commitments to sustainability. As policy turns into action and...
A Differential Scanning Calorimeter (DSC) has been added to the tools to help us with quality control with suppliers, in house, and any troubleshooting.
Polypropylene copolymer is a crystalline thermoplastic that starts with polymer grade propylene with 1-7% ethylene monomer added during bulk polymerization. Comonomer content and molecular weight distribution can be controlled in the reactor allowing for a wide range of grades and properties typically noted for the following: Chemical Resistance Low Temperature Impact Strength Lightweight Processability Price […]
Working with up to 100% regrind represents its own set of processing challenges. Based on experience and continuous improvement AGS mitigates regrind related processing issues with specially modified injection molding machines: Material conveying challenges include coarse sized chunks and longs that can obstruct the flow of plastic in standard diameter hoses/pipes. Fines generated during the […]
Aluminum molds continue to be used primarily for R&D, prototypes and lower volume production. However, today there are several high strength, heat treated wrought aluminum grades available with improved durability that actually make it a preferred choice for certain types of high volume production parts.
High impact polystyrene (HIPS) is an amorphous thermoplastic made up of polystyrene and butadiene copolymer.
Most of the time, the clamp tonnage required to keep the mold closed during plastic injection is the key factor that dictates press size. Traditionally processors have attacked clamp tonnage using higher flow materials, increasing wall thickness, shortening length of flow and specifying larger gate sizes. Now there is another bullet in the holster; iMFLUX constant low pressure molding.
