Custom Nylon Fabrication & Machining

Injection Molded. Precision-Machined. Application-Engineered.

Texas Injection Molding produces custom nylon components through injection molding and precision machining — gears, bushings, structural brackets, wear parts, and precision mechanical components in PA 6, PA 6/6, glass-filled nylon, and specialty polyamide grades engineered to your application requirements.

Custom Nylon Fabrication Solutions

Nylon (polyamide) is the engineering thermoplastic of choice for wear applications, structural mechanical components, and parts that must perform at elevated temperatures while maintaining dimensional stability under sustained load. In injection molded form, nylon delivers these properties at production economics that machined bar stock cannot match at volume.

Texas Injection Molding produces custom nylon components — injection molded for production quantities and precision machined for lower volume requirements or features that require tighter tolerances than injection molding alone achieves. Our nylon expertise covers the full polyamide family: PA 6, PA 6/6, PA 12, glass-filled grades, heat-stabilized grades, and flame-retardant variants.

Nylon Material Selection & Quality

Choosing the right nylon grade is as important as the manufacturing method. Moisture
absorption, shrinkage, and mechanical properties vary significantly across the PA family.

PA 6/6 for maximum stiffness and heat resistance in structural and underhood applications

PA 12 for dimensional stability in humid environments — lowest moisture absorption of the nylon family

GF30 for 2 to 3x stiffness increase over unfilled nylon — gears, structural brackets, high-load components

Pre-production drying to below 0.2% moisture — mandatory for defect-free nylon processing

Moisture Management in Nylon Processing

Nylon is hygroscopic — it absorbs moisture from the environment, which changes its dimensions and mechanical properties. Parts must be designed with moisture allowance in tight-tolerance fits, and pellets must be dried to below 0.2% moisture before molding.

Texas Injection Molding manages nylon moisture at every stage from material receipt through production.

Glass-Filled Nylon for Structural Applications

Adding 30% glass fiber to PA 6/6 increases stiffness 2 to 3 times, raises heat deflection temperature to over 240 degrees C, and reduces moisture absorption by approximately 40%.

For structural gears, brackets, and load-bearing components, GF30 PA 6/6 is often the correct specification — not unfilled nylon whose properties drift with moisture content.

Why Choose Texas Injection Molding?

Engineering depth that protects your investment from concept through first delivery — and a track record of rescuing programs that started somewhere else.

Nylon Grade Expertise

We select the right nylon grade for your application — not just PA 6/6 as the default. PA 6, PA 12, GF30, heat-stabilized, and FR variants each serve specific requirements.

Injection Molding and Machining

Production volumes through injection molding; tight-tolerance features and low-volume requirements through precision machining — we offer both in a single facility.

Moisture Management

Nylon moisture control from material receipt through production. Pellet drying, mold temperature management, and post-mold conditioning protocols that keep nylon parts on-dimension.

Experienced Nylon Team

Long term experience producing nylon gears, bushings, brackets, and structural components across automotive, industrial, and consumer applications.

The Right Nylon for Every Application

Nylon is not one material — it is a family of materials with meaningfully different properties. PA 6/6 for structural loading, PA 12 for humid environments, GF30 for maximum stiffness, heat-stabilized grades for continuous elevated temperature, FR grades for electrical applications.

Texas Injection Molding specifies the right grade, not the cheapest. Our nylon fabrication services cover the full production lifecycle — from material selection and DFM review through prototype tooling, production injection molding, and precision machining for features that require tolerances tighter than the molding process alone delivers.
