Metal Extrusion Die
Overview
Metal Extrusion Die is designed for aluminum profile extrusion, tube/profile forming and custom cross-section development project and is suitable for door and window profiles, industrial frame profiles, heat sink profiles, decorative profiles and custom-shaped aluminum profiles extrusion production. Die/mold can be customized according to profile cross-section, wall thickness, material grade and extrusion equipment lines pcs design solid die, hollow die, semi-hollow die and multi-hole die, help profile in die trial, die correction and batch extrusion stage maintain stable cross-section and extrusion flow condition.

Product Features
- Suitable for solid profile, hollow tube material, multi-cavity profile and complex custom-shaped cross-section extrusion forming.
- Bearing land, feeder plate and welding chamber can be customized according to profile cross-section separately design, improve extrusion flow balance.
- H13, SKD61 etc. Hot-work die steel suitable for high-temperature extrusion and continuous production conditions.
- Nitriding and polishing treatment can improve wear resistance of working surfaces, reduce profile surface galling.
- Can be combined with die trial feedback perform die correction suitable for new profile development and batch profile order.
Process and Machining Capabilities
We design metal extrusion dies around the profile cross-section, wall thickness ratio, alloy grade, extrusion ratio and equipment tonnage.
Solid dies come down to bearing land length, extrusion flow speed and cross-section contours. Hollow dies are about the bridge, welding chamber, mandrel strength and weld line position. For heatsink profiles the priority shifts to fin spacing, base plate flatness and flow stability.
On the machining side, the sequence runs from material blanking and rough machining through heat treatment, CNC finishing, EDM, wire cutting, grinding, polishing, nitriding and trial correction. Multi-cavity, thin-wall and deep-slot profiles get extra attention on mandrel support, local flow resistance and bearing land grinding damage.

Quality Control
The company has passed ISO 9001 quality management system certification, with the certified scope covering aluminum product processing and sales. Metal Extrusion Die can be customized according to profile drawings, Die/Mold Structure and die trial requirements inspect die/mold material, hardness, bearing land dimensions, flow-guiding structures, welding chamber contours and assembly surface condition.
Die/Inspection for mold delivery before can focus on critical dimensions, hole positions, cavities contours, bridge condition, nitriding layer appearance, anti- rust packaging and die trial feedback. For requiring mass production extrusion die/mold, can combine sample trial profile dimensions, surface condition and extrusion flow balance perform die correction confirm.
Metal Extrusion Die can be packaged with rust preventive oil, protective film, foam, wooden crate or pallet packaging. Working surfaces, mandrel, assembly surface and positioning structure additional anti-collision protection, reduce transportation process in knocks, rust and surface scratches risk.
Frequently Asked Questions
Q: What is the minimum order quantity (MOQ)?
-
A: Metal Extrusion Die standard MOQ for 1 set.multiple cross-section profile, series profile or batch die/mold order will be confirmed according to cross-section quantity.
Q: What is the lead time?
-
A: sample mold usually takes 15–25 days, batch die/mold usually takes 25–40 days. Complex hollow die, multi-cavity mold and requiring multiple trial mold runs adjustment order lead time will be longer.
Q: Can the die be customized according to a profile cross-section drawing?
-
A: Yes. Can be customized according to profile cross-section, wall thickness, material grade, external profile dimensions and extrusion equipment lines pcs design extrusion die/mold.
Q: Can hollow profiles and multi-cavity profiles be produced?
-
A: Yes. Hollow tube, multi-cavity tubes, heat sink profiles and complex custom-shaped profile can be customized according to flow guidance, flow division and welding fit structure perform die/mold design.
Q: Is die trial recommended?
-
A: it is recommended to perform trial mold confirmation. Die trial can inspect profile dimensions, surface condition, extrusion flow balance and cross-section stability and according to sample trial feedback adjustment bearing land local structure.
