The evolution in plastics technology has revolutionized the firearms industry over the last fifty years, with lighter, stronger and more durable precision technologies changing the industry.
At the same time, producing these parts is a mounting challenge, as engineering designs push the envelope of current molding methodologies. One of the major manufacturers of complex component parts for a host of these cutting-edge firearms products has been in the business of making highquality, functional products in the military, defense, and law enforcement after-market sectors for over 10 years. They excel in rugged components for the munitions market that can take all the abuse that a hostile environment imposes.
Working with well-known firearms manufacturer’s, the company designed and produced components for the AR-15 rifle, as well as new technology for shotgun platform’s, high-end weapon components, such as butt stocks and foregrips, cartridge magazines, and a host of other critical accessories and components that are lighter and more durable than previous models. That translated to direct metal conversions to plastic, and the need for proprietary technologies and highly glassfilled nylons that are super-tough for strength and functionality, through mud, dirt and even under water.

During this process, PTA Plastics developed some phenomenal designs to allow the building of our molding tools. We also suggested several changes that remain part of our ongoing process with these products to this day; for example, additional clearance or features for form, fit, function and manufacturability.
PTA pushed the envelope using hydraulic and servodriven actions, as well as slides within slides. We developed an engineering solution for ejecting parts along an arc, making frame sizes smaller and actions work better. PTA Plastics is proud to be an ITAR supplier to our customers in the defense industry. We have a passion for complex assignments that demand the very best in injection molding solutions.
