Titanium Extrusion Process Spectrum
Three integrated extrusion workflows covering the full titanium profile production spectrum — from hot extrusion of long-length structural profiles to precision post-processing and quality-certified delivery.
Hot Titanium Extrusion
6,000+ Ton Hot Extrusion of Long-Length ProfilesPushing pre-heated titanium billets (950-1050°C) through precision-ground die apertures at 6,000+ metric tons — producing long-length near-net profiles with aerospace-grade surface finish and dimensional accuracy.
- Near-net extrusion of complex asymmetric structural profiles
- Seamless tube and hollow section production through porthole and bridge dies
- Long-length straight profiles (up to 12 m) for structural and architectural applications
- Solid round, rectangular, and custom-shaped bars and rods
Post-Extrusion Processing (Drawing, Straightening, Sawing)
Precision Drawn & Cut-to-Length ProcessingExtruded titanium products requiring secondary drawing, straightening, and cutting-to-length for precision dimensional compliance. From near-net extruded blanks to finished machined components.
- Solid bars and rods in round, hexagonal, and custom cross-sections
- Seamless tube and pipe — ID/OD dimensions from 20 mm to 300 mm with wall thickness down to 2 mm
- Structural angles, channels, T-sections, and other architectural profiles
- Custom asymmetric profiles for aerospace and defense applications
Production Flexibility & Quality Assurance
Flexible Lot Sizes & Multi-Alloy CapabilityOur extrusion facility processes titanium alloys through dedicated die sets with glass-lubricated tooling — delivering near-net profiles that minimize downstream machining requirements and material waste.
- Small-to-medium production runs (500-5,000 kg per order) with flexible alloy changeover
- Titanium Grade 2, Grade 5 (Ti-6Al-4V), and Grade 9 (Ti-3Al-2.5V) — the most commonly extruded titanium alloys
- Surface finish as-extruded: Ra 1.6-3.2 µm (with glass lubrication) — suitable for direct use or minimal post-processing
- Full NDT capability: ultrasonic (UT), dye-penetrant (PT), and dimensional inspection for certification packages
Extrusion Capacity Dashboard
Our extrusion press capacity — press force, maximum profile lengths, billet pre-heat range, and extruded profile diameter limits.
Extrusion Press Force
Industrial-grade hydraulic extrusion press generating extreme, controllable force to push pre-heated titanium billets through precision-ground die apertures.
Max Linear Profile Dispatch
Pushing single-piece uninterrupted alloy structures up to 12 meters in length — accommodating full-length structural profiles without butt-welding or mechanical joining.
Pre-Heat Range
Billet heating in multi-zone controlled atmosphere furnaces ensures uniform temperature distribution prior to extrusion, preventing localized overheating or underheating.
Extruded Profile Diameter Range
Diameter range of extruded solid bars, tubes, and custom profiles — from small-diameter rods to large structural sections.
All specifications measured under controlled conditions per ISO 2768-m and AS9100D. Actual results depend on material grade, geometry complexity, and batch size.
Die Lubrication & Thermal Control Know-How
Conquering titanium's high-temperature sticking, die wear, and linear distortion requires specialized glass lubrication and isothermal tooling control. Here's how we achieve aerospace-grade extruded surfaces and straightness.
Advanced Molten Glass Envelope Lubrication
During hot extrusion of titanium at 900-1050°C, the extreme pressure (6,000 metric tons) and temperature cause severe adhesion between the titanium billet and the die steel surface — producing surface tearing, galling, and characteristic 'fish-bone' wave patterns on the extruded profile that render the surface unfit for aerospace or structural applications and require extensive post-extrusion grinding or scrapping.
Aerospace-Certified Micro-Glass Powder Matrices Forming Liquid Boundary Layers
- Aerospace-certified micro-glass powder (particle size 50-200 µm) applied as a uniform coating to the preheated titanium billet before insertion into the extrusion press — the glass composition is precisely formulated to melt at extrusion temperature (950-1050°C), forming a continuous viscous liquid boundary between the billet and the die bearing surface
- The molten glass layer (viscosity 10³-10⁵ Poise at extrusion temperature) creates a hydrodynamic lubrication film 10-30 µm thick — completely isolating the titanium from the die steel and eliminating metal-to-metal contact that causes surface tearing, galling, and fish-bone wave formation
- Continuous lubrication throughout the entire extrusion stroke: the glass coating is replenished from a reservoir in the dummy block, maintaining the liquid boundary layer as fresh billet material feeds into the die — ensuring uniform surface quality from the first meter to the last
- Result: surface finish Ra 1.6-3.2 µm directly from the extrusion press — no surface tearing, no galling, no fish-bone waves — eliminating the need for secondary surface conditioning and maximizing material yield
Isothermal Tooling Cycles & Stretch Straightening
Titanium's high extrusion temperature (900-1050°C) and low thermal conductivity create significant thermal gradients across the die face during extrusion — causing differential material flow rates across the profile cross-section that result in axial twist, longitudinal bowing, and cross-sectional distortion. Without active thermal management and post-extrusion correction, these geometric defects render long-length extruded profiles unsuitable for structural assembly.
Inductive Die Heating Loops for Isothermal Flow & Multi-Ton Stretch Straightening
- Inductive heating coils embedded in the die holder maintain the die temperature at the target set point (typically 950-1000°C) with ±5°C accuracy throughout the entire extrusion cycle — eliminating the progressive cooling that would otherwise occur as the die conducts heat away from the extrusion, ensuring uniform metal flow from start to finish
- Multi-zone inductive control: individual heating zones at the die center, bearing surface, and periphery are independently regulated — compensating for the higher heat loss at the profile edges vs. the center, ensuring uniform material velocity across the entire cross-section and eliminating differential flow-induced twist
- Post-extrusion stretch straightening on a multi-ton hydraulic tension bed: the extruded profile is gripped at both ends and subjected to a controlled tensile load (typically 1-3% permanent elongation) — this plastic deformation removes axial twist, longitudinal bow, and cross-sectional distortion while improving the straightness to within ±0.5 mm/m
- Result: extruded profiles delivered with straightness within ±0.5 mm/m, twist-free, and dimensionally compliant — ready for direct integration into structural assemblies without secondary straightening or rework
