Drake Plastics’ Quality Management System is certified to the worldwide aerospace industry’s AS9100D(2016) and ISO 9001:2015. We apply these rigorous aerospace requirements to all customers, regardless of industry.
We specialize in converting a variety of grades of ultra-high-performance polymers into extruded machinable shapes, injection molded parts, and precision machined parts. The Torlon® PAI formulations we process and fabricate include Torlon 4203/ 4203L, 4275, 4301, 5030 and 7130 and other specialty grades. Within the PEEK polymer family, the grades we offer include Victrex 450G, CA30, GL30, FC30 and High-Temperature PEK “HT”, as well as KetaSpire KT-820 NT, CF30, GF30 and XT920 high-temp PEEK. Drake also offers Ryton® R-4 PPS, AvaSpire® PAEK and UltemTM 2300 PEI.
Our extrusion equipment incorporates Drake-engineered and built hardware and systems that let us optimize and maintain process parameters specific to each material. This rigid control helps ensure consistent quality, appearance and performance. As an added quality assurance measure, Drake’s single-piece workflow approach to manufacturing focuses on producing one flawless product at a time.
For both quality and efficiency, Drake also continually invests to maintain state-of-the-art capabilities in our parts manufacturing operations. The CNC equipment in our precision machining facility and the SPC and in-cavity process control of every shot from our injection molding department represent the best available technology for producing ultra high-performance polymers to Drake standards.
In addition, our inspection equipment matches the precision with which we make parts. It includes density verification, CT scanning capabilities, optical comparators, surface finish inspection equipment, CMMs and many other tools as needed to meet customers’ requirements.
We offer DSC thermal characterization and can provide machined or injection molded ASTM mechanical test specimens and testing services utilizing our calibrated Instron Universal Testing Machine. Injection molded or machined parts also can be tested according to customer specifications and requirements with fixturing specific to each part design.
Lean operating practices characterize all areas of our business. Our team consistently works to improve efficiency and maintain the flexibility to serve customers’ needs from prototypes, development work and small lot custom products to high volume manufacturing.
Drake Plastics pursues perfection in the products we produce and services we render.
At regular intervals, Drake Plastics will review its quality system and objectives and change as necessary to continuously improve both internal and external quality. Resources to solve problems and meet our quality objectives will be allocated with utmost urgency.

Torlon PAI Post-Curing
Every Torlon PAI product supplied by Drake is post-cured to achieve a typical core Tg value of 540°F/282°C (midpoint). Drake has optimized our post cure cycles to achieve material properties which are required to ensure key properties of strength, toughness, wear, and chemical resistance. This provides customers with strong machinable shapes that make ultra-wear resistant parts as well as structural and electrical components.
Torlon PAI Re- Curing Service
Drake Plastics offers Torlon PAI machined parts complete with re-cure after fabrication when specified. We also support our Torlon PAI stock shapes customers with economical re-cure services at fast turn-around times. Although Drake-produced Torlon PAI stock shapes are thoroughly cured, re-curing machined parts restores the imidized outer layer which forms on PAI at cure temperatures (typically 260°C/ 500°F). This imidized layer optimizes resistance to wear and chemical attack, which may benefit specific components based on their application environment.
With the exception of Torlon products which are specially post-cured to optimize properties, Drake anneals every stock shape in cycles customized for both the polymer formulation and the product size. A slow, tightly controlled cool-down from the material’s Tg (glass-transition temperature) effectively relieves stresses that can occur from process temperatures and pressures while the polymer is being converted into the final product. This step yields dimensionally stable stock shapes that hold precise tolerances in machining and have optimal physical and chemical resistance properties.
Annealing fiber-reinforced polymers
PEEK, RYTON R-4 PPS, Ultem 2300 and other glass and fiber-reinforced grades
During annealing, an unreinforced or “neat” material’s polymer chains move relative each other and “relax” slowly under uniformly controlled cooling conditions to relieve internal stresses. With glass and carbon fiber reinforced polymer formulations, the rigid internal fibers maintain their position within the material matrix during annealing. As a result, the polymer chains are not as free to relax with fiber reinforcement, and annealing, while helpful, has a somewhat lesser effect on reducing internal stresses than in unreinforced materials.
Custom annealing cycles
Custom annealing to achieve specific objectives such as crystallinity targets or dimensional control are available upon request.
