The primary drivers for lead times are the complexity and fabrication time for the custom die design, the availability of specialized reinforcement materials or resin systems, and the supplier's current production schedule. Simple profiles using common materials can have shorter lead times, but intricate cross-sections or novel material combinations require more extensive tooling development and testing, extending lead times significantly.
Ensuring mechanical properties requires a precise specification of the fiber architecture (e.g., percentage of unidirectional rovings versus continuous strand mat) and the exact resin system. Work closely with the pultruder to define the optimal fiber volume fraction. Reputable suppliers will also have in-house or third-party testing capabilities to validate the mechanical properties of sample batches against your specifications, often utilizing ASTM standards for testing protocols.
Pultrusion is ideal when you need a continuous profile with very high strength-to-weight ratios, excellent corrosion resistance, specific electrical insulation properties, or thermal stability that traditional metals or plastics can't offer. Unlike extrusion, pultrusion uses thermoset resins and continuous fibers, resulting in superior strength and stiffness. Roll forming, while good for metals, cannot achieve the composite material properties or environmental resistance of pultrusion.
Common resin systems include polyester (cost-effective, good general-purpose), vinyl ester (superior corrosion and chemical resistance, slightly higher cost), epoxy (highest strength, excellent adhesion, often higher cost, specialized applications), and phenolic (excellent fire/smoke/toxicity properties, but more brittle). The choice depends on the end-use environment, required mechanical properties, and budget, with cost generally increasing with performance capabilities.
While pultrusion is inherently a continuous process for constant cross-sections, modern die design and processing techniques allow for surprisingly complex shapes, including hollow profiles, multi-void sections, and intricate geometries. However, very sharp internal corners or extreme thickness variations can be challenging. For non-uniform or highly complex parts, secondary machining or combining pultrusion with other fabrication methods may be necessary.
Beyond ISO 9001, look for suppliers with specific industry certifications like ASTM D7290 (for structural profiles), AWWA (water infrastructure), or UL listings (electrical applications). Crucially, inquire about their in-house testing equipment, such as universal testing machines for tensile/flexural strength, impact testers, and laboratories for chemical resistance or fire performance, ensuring they can verify your stringent specifications.
