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.

Plastics Profiler-High Impact Polystyrene
High impact polystyrene (HIPS) is an amorphous thermoplastic made up of polystyrene and butadiene copolymer.
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.
Plastics Profiler ABS+PC Blends
ABS+PC are blends of the amorphous engineering thermoplastics, acrylonitrile-butadiene-styrene (ABS) and polycarbonate (PC). ABS+PC is similar in many ways to its component resins, but combines the mechanical and thermal properties of polycarbonate with the processability and economy of ABS.
Polyethylene By Density
Polyethylene is the largest volume thermoplastic used today. Polyethylene is available in a variety of grades that have a wide range of properties and are classified according to density.
Material Line-Up: Nylon 6 vs. Nylon 66
Glass fiber reinforced Nylon is a material often used to replace metal due to its higher strength to weight ratio. While Nylon 6 and Nylon 66 offer similar benefits there are distinct differences that should be taken into account when selecting between the two grades.
Non-Appearance Plastic Parts: Natural vs. Black
Over the last twenty-five years the majority of non-appearance, functional plastic parts that AGS has run across are black in color. This still leaves a significant number of these parts being molded in virgin, natural plastic. This begs the question, why are some non-appearance parts molded in natural instead of black color?
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 […]
