What’s your toughest part challenge?

At Allegheny Performance Plastics, we specialize in injection molding Torlon®, a high-performance polyamide-imide (PAI) trusted across critical industries like aerospace, automotive, defense, and EV.

As an approved Torlon injection molder by Syensqo—the manufacturer of Torlon—we deliver consistent quality, high-precision tolerances, and material integrity you can count on.

What is Torlon^®?

Torlon® is a high-performance polyamide-imide (PAI) thermoplastic developed by Syensqo, known for its unmatched strength, stiffness, and resistance to wear, chemicals, and extreme temperatures. Unlike standard polymers, Torlon maintains its mechanical properties at temperatures up to 260°C (500°F), making it ideal for demanding environments where metals or lower-grade polymers fail. Because of its unique performance profile, injection molding Torlon is extremely difficult.

Why Choose Allegheny for Injection Molding Torlon^®?

With decades of experience in advanced thermoplastics, we understand the unique processing challenges of Torlon. From its extreme temperature resistance to its exceptional strength and wear performance, Torlon demands precise control during every phase of injection molding.

Our high-performance molding capabilities enable us to manufacture complex parts that meet tight specifications in high-stress environments. When you partner with Allegheny, you benefit from:

Syensqo-approved processing expertise
Reliable dimensional stability and high thermal performance
Custom-engineered solutions for friction, wear, and chemical resistance

When to Specify Injection Molded Torlon®

Torlon® PAI is ideal for parts that require:

Continuous use temperatures above 260°C (500°F)
Excellent wear resistance under load
Outstanding dimensional stability and creep resistance
Electrical insulation and chemical inertness

Common applications include:

Powertrain and transmission components
Seals, bushings, and wear rings
Aerospace connectors and brackets
EV battery system components and insulators

Whether you’re designing for a high-temperature aerospace application or solving wear and friction problems in EV systems, injection molding Torlon with Allegheny means performance without compromise.

Manufacturing with Torlon

Manufacturing Torlon parts can be accomplished three ways:

1

Stock shapes for machining prototypes
2

Machining parts
3
Injection-molding parts

Allegheny regards all three as core competencies and actively supports volumes from a single prototype piece up to millions of production pieces annually. We manufacture high volume parts that are all injection-molded, and we also manufacture parts that are more complex and require machining after being molded. We have the largest Torlon-part manufacturing infrastructure in North America, along with the decades of employee expertise required to ensure that your part will be in excellent hands.

Torlon is technically a thermoset polymer, which are not commonly injection-molded. This means that every step of the manufacturing process is an exact science. Torlon parts that have been injection-molded require an extended post-curing process, for example.

Happy Customers

“We had a severe wear problem…we were getting so close to production…and in just a month-long period [of working with Allegheny] we were in the prototype phase of a solution part…The product itself, out of the gate, worked beautifully. The wear problem was like flipping a switch and it just turned the wear off. It was night and day for us. We couldn’t wear the samples Allegheny provided.

[Allegheny excelled] at all around communication and support. And then the product itself was just stellar.”
