Castings, Moldings, & Extrusions

Steiner develops precision-cast and molded components for durable, aesthetic, and high-performance assemblies.

Let us develop a custom casting or molding solution built for your design, strength, and finish requirements.

Plastic Extrusions

Continuous plastic forming process engineered for producing consistent cross-section profiles, ideal for long components requiring dimensional stability and cost-efficient production.

Custom Profile Design: Supports complex geometries including channels, slots, and internal features tailored to your application.
Material Versatility: Compatible with PVC, ABS, polycarbonate, HDPE, and other engineering plastics to meet strength, flexibility, and environmental requirements.
Length Flexibility: Profiles can be produced in continuous runs and cut to exact lengths, minimizing waste and secondary processing.
Secondary Operations Ready: Easily supports post-extrusion machining, drilling, co-extrusion, and finishing for fully integrated assemblies.

Injection Molding

High-precision plastic forming process engineered for complex, high-volume components, delivering consistent quality, tight tolerances, and production-ready repeatability.

Complex Part Capability: Supports intricate geometries, thin walls, and integrated features such as clips, bosses, and living hinges.
High-Volume Efficiency: Ideal for scalable production programs, providing excellent part-to- part consistency with low per-unit cost at volume.
Material Flexibility: Compatible with a wide range of engineering plastics and resins to meet structural, thermal, chemical, and aesthetic requirements.
Production-Grade Finishes: Enables molded-in textures, colors, and surface finishes while minimizing secondary operations.

Overmolding

Advanced multi-material molding process that bonds soft or functional polymers over rigid substrates, creating integrated components with enhanced grip, protection, and visual appeal.

Multi-Material Integration: Combines rigid plastics or metal inserts with elastomers in a single molded assembly, reducing part count and assembly steps.
Improved Ergonomics: Adds soft-touch surfaces for better grip, comfort, and vibration dampening in user-facing components.
Enhanced Durability: Provides sealing, impact resistance, and environmental protection for electronics and mechanical assemblies.
Design Freedom: Enables contrasting colors, textures, and functional zones while maintaining structural integrity.

Aluminum Extrusions

Precision-formed aluminum profiles engineered for lightweight strength, structural stability, and scalable production across a wide range of industrial and consumer applications.

Custom Profile Capability: Enables complex cross-sections with integrated channels, ribs, and mounting features to reduce assembly and part count.
Lightweight Structural Strength: Delivers excellent strength-to- weight performance with inherent corrosion resistance for indoor and outdoor use.
Flexible Length Production: Extrusions are produced in continuous runs and cut to exact specifications, supporting both short and long- form components.
Finish Ready: Supports anodizing, powder coating, and machining for clean aesthetics and production-grade durability.

Die Casting

High-precision metal components produced through advanced die casting processes, delivering complex geometries, tight tolerances, and production- ready consistency at scale.

Precision Tooling: Hardened steel molds ensure repeatable accuracy and dimensional stability across high-volume production runs.
Complex Geometry Capability: Enables intricate shapes, thin walls, and integrated features that reduce secondary machining and assembly.
Superior Surface Finish: Produces smooth, uniform parts suitable for anodizing, powder coating, painting, or plating with minimal post- processing.
Production Efficiency: Ideal for medium-to-high volume programs, providing excellent part-to-part consistency while minimizing material waste and cycle time.

Sand Casting

Versatile metal forming process designed for larger, lower-volume, or complex components, offering cost-effective tooling and flexible design capability across a wide range of alloys.

Low Tooling Investment: Ideal for prototypes and small-to-medium production runs, with affordable mold creation and fast design iteration.
Large Part Capability: Supports oversized and thick-wall components not practical with die casting or permanent molds.
Broad Material Options: Compatible with aluminum, iron, steel, and specialty alloys to meet structural, thermal, or corrosion-resistance requirements.
Post-Machining Ready: Castings are optimized for secondary CNC operations to achieve tight tolerances and critical surface finishes where needed.

Forging

High-strength metal forming process that reshapes heated material under pressure to create dense, structurally superior components with excellent fatigue resistance and long-term durability.

Enhanced Mechanical Properties: Grain flow follows part geometry, delivering higher strength, impact resistance, and reliability versus cast or machined parts.
Near-Net Shape Capability: Produces parts close to final form, reducing material waste and minimizing secondary machining.
Consistent Part Integrity: Eliminates internal porosity common in castings, ensuring uniform structure and dependable performance in critical applications.
Scalable Production: Supports both closed-die and open- die processes for low-to-high volume programs requiring rugged, load-bearing components.
