1. Project Overview
This aluminum extrusion production line is a core upstream manufacturing workshop for all aluminum alloy metal parts, including bicycle handlebars, heat sinks, automotive structural parts, and custom CNC blanks. The full-automatic integrated line realizes one-stop forming of solid & hollow aluminum profiles from raw aluminum ingots, supplying standardized semi-finished blanks for subsequent CNC machining, stamping, surface treatment and assembly processes.
Supported alloy grades cover 6061, 6063, 7075 series aluminum, which are widely applied in cycling equipment, new energy, electronic hardware and machinery industries. The line balances mass bulk production and small-batch customized profile development, perfectly matching flexible order demands from global B2B clients.
2. Core Production Flow of The Line
- Raw Material Feeding & Homogenization: Aluminum ingots are heated for homogenization to eliminate internal alloy stress, improving ductility for smooth extrusion.
- Hot Extrusion Forming: Heated billets are pushed through precision custom molds under high hydraulic pressure to form customized cross-section aluminum profiles.
- Online Water/Air Quenching: Real-time rapid cooling locks target mechanical properties (tensile strength, hardness) to meet RoHS, 3C and cycling part standards.
- Stretching Straightening: Eliminate extrusion bending & twisting to guarantee flatness tolerance within ±0.05mm.
- Precision Cutting: Automatic fixed-length cutting according to customer drawing requirements.
- Aging Heat Treatment: Artificial aging boosts alloy hardness for high-load applications like bike components and heat sinks.
- Finished Profile Sorting & Temporary Storage: Classified storage before transferring to CNC, stamping or surface treatment workshops.
3. Key Equipment & Technical Advantages
- Large-tonnage hydraulic extrusion press, supporting complex hollow & solid custom cross-sections
- Closed-loop temperature control system to stabilize alloy mechanical consistency batch by batch
- Automatic stretching straightener to minimize profile deformation, reducing subsequent CNC machining allowance
- Compatible with multi-alloy switching, fast mold replacement for rapid small-order trial production
- Full-process real-time data monitoring for traceable quality inspection
- Low energy consumption circulation heating system to lower mass production costs for clients
4. Matching Downstream Workshop Collaboration
This extrusion line works seamlessly with all internal production departments listed in the project catalog:
- Supplies standard aluminum blanks for 5-Axis CNC Machining workshop (bike handlebars, heat sink skiving parts)
- Provides aluminum base materials for integrated metal surface treatment line (anodizing, polishing, sandblasting)
- Supports laser engraving & marking processes as pre-formed aluminum substrates
- Semi-finished profiles are transferred to assembly workshop for finished product assembly
- All finished extruded profiles go through Precision Manual Inspection for dimensional & appearance verification before warehouse inventory storage
5. Quality & Compliance Standard
All extruded aluminum profiles pass full dimensional inspection, tensile hardness testing and surface flaw screening. Raw aluminum materials and finished profiles comply with RoHS, CB, CQC industry certifications, meeting global import requirements for bicycle, electronics and mechanical metal parts. Custom extrusion mold development service is available for clients with exclusive proprietary product designs.
6. Service Scope for Clients
