3D Printing vs. CNC Machining of Plastic Parts

The process of 3D Printing, also known as additive manufacturing, has now been developed for several materials including plastic and metal. This article will focus on 3D printing compared to CNC machining of plastic parts.
 
The 3D Printing process is an additive process during which layers of molten plastic are added until the part is completely formed.  These layers can often be noticed, and this can be an aesthetic issue. In evaluating whether or not this is the right approach the two key questions to be answered are:
1) What is the application?Read more

ABS: Acrylonitrile Butadiene Styrene

ABS: Acrylonitrile Butadiene Styrene
Acrylonitrile butadiene styrene (ABS) is a plastic that is a terpolymer, a polymer consisting of three different monomers. ABS is made by polymerizing styrene and acrylonitrile in the presence of polybutadiene.  Acrylonitrile is a synthetic monomer made up of propylene and ammonia while butadiene is a petroleum hydrocarbon, and the styrene monomer is made by the dehydrogeneration of ethyl benzene. Dehydrogenation is a chemical reaction that involves the removal of hydrogen from an organic molecule and is the reverse of hydrogenation. … Read more

Craftech Industries Receives ISO 9001:2015 Certification

Hudson, NY — Craftech Industries, Inc. is pleased to announce that it has received the ISO 9001:2015 certification. This is an upgrade from its previous ISO 9001:2008 certification. ISO 9001:2008 certification is becoming obsolete in September 2018. Therefore, it became important to Craftech to pursue the latest ISO 9001:2015 certification.
ISO 9001:2008 focused on meeting customer expectations and delivering customer satisfaction.However,  ISO 9001:2015 focuses on performance while emphasizing the adoption of risk-based thinking and a Plan-Do-Check-Act cycle throughout the organization. … Read more

TORLON® Polyamide-imide

TORLON® is the Solvay brand name for polyamide-imide or PAI. Polyamide-imides demonstrate exceptional mechanical, thermal and chemical resistance properties making them well suited to severe environmental service. PAIs have exceptionally high heat performance with a continuous service temperature of 260°C or 500°F and are inherently flame resistant. They are known to have the highest strength and stiffness at higher temperatures of any thermoplastic. Torlon resists wear, creep and is also extremely durable from cryogenic temperatures to 275°C (535°F). … Read more

The Development of Modern Plastics

During the late 19th century natural resources such as wood, ivory, and tortoiseshell were being depleted at a rapid rate. Ivory and tortoiseshell were highly sought-after materials for luxury items including hand-carved combs, hand-held mirrors, jewelry boxes, and many high-end personal items enjoyed by the well-to-do at the time. These materials were also used extensively for medical and dental instruments and more utilitarian uses such as pistol grips.
With the immense technological progress in chemistry and a need to find a replacement for dwindling natural resources, … Read more
