AGS Technology, a leader in the plastic injection molding industry, is proud to announce the graduation of four technicians from the Paulson ProMolder 1 processing course. These dedicated individuals have successfully completed the rigorous online course and...
AGS Machine Modifications to Process Regrind
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 […]
Production Grade Aluminum for High Volume Injection Molds
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.
A Disruptive Solution to Reducing Clamp Tonnage
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.
AGS Screw Design Optimizes Distributive Mixing
Most custom injection molding companies use a general purpose screw design in their machines to process the widest range of plastic materials. From the very beginning, AGS Technology has specified a mixing screw design. AGS’ initial injection molding screw design was based on years of compounding experience extruding recycled plastics. This original design helped ensure […]
Fingerprinting Glass Reinforced Materials
Every plastic material has a unique performance “fingerprint” that identifies not only the polymer type but reinforcement level as well. AGS Technology’s raw material testing laboratory has the equipment and skilled personnel to run and analyze the corresponding battery of tests to help solve plastic material identification and performance on a daily basis. For glass […]
ASTM D 4000 Callout: A Fast, Effective Alternative to the OEM Approved Material Source List
Most large OEM’s have their own internal engineering teams to help evaluate and approve materials that will be used in the construction of their product. Plastics is no exception with OEM’s maintaining an approved material source list assigned to defined physical, thermal, and environmental performance specifications. This formal approval process can be time consuming and […]
Formulating Toughness of Polycarbonate Using Viscosity and Impact Modifiers
Polycarbonate is available in a wide range of viscosities for blow molding, extrusion, and injection molding applications. A melt flow rate (MFR) test using an extrusion plastometer is an excellent way to determine the viscosity of polycarbonate. Below are typical melt flow rate ranges based on ASTM D1238 (condition 300/1.2): Blow molding grades (eg. 5 […]
