The minimum wall thickness of profile is only 0.4mm, and the tolerance requirement is ±0.04mm.This extrusion technique is often referred to as precision aluminum extrusion.
The tolerance of some small precision aluminum profiles is more than half of that of the JIS standard special grade, and the tolerance of general precision aluminum profiles is between ±0.04 ~ ±0.07mm.
The minimum wall thickness of A1050, A1100, A3003, A6061, A6063(low and medium strength alloy) small precision extruded profiles is 0.5mm, the minimum fracture area is 20mm2. The minimum wall thickness of A5083, A2024, A7075 (medium and high strength aluminum alloy) small precision extruded profiles is 0.9mm, the minimum fracture area is 110mm2.
Generally speaking, aluminum alloy hot extrusion deformation degree is large, extrusion temperature and speed changes, extrusion equipment to the neutral, die deformation, etc., are easy to affect the precision of the profile size, and their mutual influence factors are difficult to overcome.
The mold is the most direct factor that affects the dimensional precision of extruded products.to ensure that the sectional size of extruded product remains unchanged or changes little in the production, the rigidity, heat resistance and wear resistance of the mold must meet certain requirements.
First to ensure the mold under high temperature and high pressure is not easy to deformation, has a high heat resistance, more stringent for precise extrusion, requirements in the working temperature (500 ℃), mold material yield strength is not less than 1200 n/was. The second needs a high wear resistance, which mainly depends on the hardness and thickness of nitriding layer general requirements the hardness of nitrided layer above 1150 hv, nitriding depth between 0.25 mm to 0.45 mm, and the changes of the mould size of the nitride should be within 0.02 mm.
For the section has the solid profile and the hollow profile of the suspension wall, but also consider the elastic deformation of the mold, in order to make the mold to ensure a certain stiffness, you can consider the appropriate increase in the thickness of the mold or with similar shape of the special pad.
To control the change of profile opening size, a diversion groove can be made on the mold to control the flow of metal.
