Custom Fabrication Capabilities

Extrusion & Secondary Processing
Profiles are extruded and then processed through CNC machining, punching, or cutting according to engineering drawings.

Cutting Process
Carbide saw cutting is used for standard lengths. End faces and dimensions are controlled within tolerance limits.

Punching & Drilling
Punching and drilling are carried out based on supplied engineering drawings.

Welding
TIG and MIG welding are available through manual and semi-automated stations depending on structural requirements.

Bending
Rotary-draw and stretch-bending equipment are used for forming operations based on specified radius and profile geometry.

CNC Machining Tolerance
Secondary CNC machining tolerance is controlled within ±0.1 mm and verified with calipers.

Quality Control & Traceability

Quality Control
Optical Profilometry: Cross-section scanners compare dimensions with CAD drawings.

Hardness Verification: Handheld testers measure cross-sectional hardness to confirm correct precipitation hardening.

Surface Inspection: 100% visual and tactile inspections detect extrusion marks, blisters, or surface defects.

Traceability
Bar-Code Serialization: Each production lot is assigned a barcode for traceability from billet to shipment.

Billet Log Pairing: Finished lots are permanently cross-referenced to original melt numbers and supplier batches.

Routing Documentation: Digital travelers record operators, machinery parameters, and processing dates for every bundle.

Industrial Applications

Application Sector	Specific Use
Curtain Wall Systems	Framing structural glass corners
Solar Panel Arrays	Base racking corner mounts
Truck Trailer Frames	Side-wall upper rail reinforcement
Railway Carriages	Internal seating floor anchors
Industrial Conveyors	Asymmetric guide rail supports
Aviation Cargo Racks	Overhead structural pallet framing

Packaging & Logistics

Wooden Crate Enclosures: Heavy-duty ISPM-15 certified timber boxes protect bundled profiles from side impact during transport.

Moisture-Absorbent Desiccants: Silica gel packs are placed inside VCI film bags to reduce surface oxidation during transport.

Weight-Optimized Loading: Container configuration software calculates loading to reduce load shift during transit.

FAQ

Q: What is the standard minimum order quantity (MOQ) for custom-tooling production runs?

A: Custom production runs typically require a minimum order of 500 kilograms per extrusion die.

Q: Can we request custom-length cutting to minimize scrap loss at our assembly site?

A: Yes. Custom cut lengths between 1,000 mm and 7,000 mm are supported.

Q: Does your wooden packaging comply with international customs regulations?

A: Yes. All timber packaging is heat-treated and marked according to ISPM-15 requirements.

Q: What is the typical lead time for sending physical pre-production samples for client approval?

A: Sample profiles from existing tooling are typically dispatched within 7 to 10 working days after request confirmation.
