Name of Part or Process: Gear box
Gear box with high requirements on position and diameter of the holes in order to avoid axial displacement and noises (0.08mm hole distance tolerance with spc) without any machining. Achieved flatness of 0.18mm over the entire part without any machining.
Magnesium Child’s Bicycle
Name of Part or Process: Magnesium Child’s Bicycle
Mg Alloy frame for children’s bicycle is a kind of technological breakthrough from the traditional welding of iron and aluminum frames. Mg alloy frame produces a unibody adopting magnesium alloy extrusion process and replaces the traditional welding technology. The linear flow of the entire body is without any welded joints so there is no risk of breaks in the welding process. The shape of the frame is more diversified and the product is more lightweight. Because the magnesium alloy material has excellent shock absorbing performance, the children’s bicycle can protect children’s physical and mental health during riding, weaken the sense of turbulence, and bring a more comfortable riding experience in a better way.
As the world’s most populous country, there are 16.55 million newly-born children each year in China. With widespread education and economic growth, the expenditure for children in the family increases year by year, and the usage amount of the children’s bicycle increases progressively year after year. The magnesium alloy frame & die casted products of the children’s bicycle has been widely recognized by the market as a kind of lightweight high-end product. China’s domestic major-brand manufacturer has developed self-owned brand, using for the children’s magnesium alloy bicycle, magnesium alloy balanced bicycle for children. The die casting of magnesium alloy for children’s bicycle is mainly used on the frame, the wheel circle, the front fork, and other parts of the bicycle resulting in 70% of the major structures in the bicycle being made of magnesium alloy. The total quantity of sales of children’s magnesium alloy bicycle is 530,000, and 180,000 of magnesium alloy balanced bicycle for children last year.
Thermomechanical processing of Allite SuperMag ZE62
Name of Part or Process: Thermomechanical processing of Allite SuperMag ZE62
Thermomechanical processing, specifically forging of magnesium alloys, has traditionally been challenging due to the poor ductility of conventional magnesium alloys. Forging, which pressurizes and deforms the crystalline structure of the material, holds great potential to create high strength and exceptionally light weight articles, particularly when the material grain size is kept small during deformation.
ALLITE® Inc. has developed unique rare earth magnesium alloys and designed ZE62 to deliver a superior combination of elongation and strength. ALLITE® Inc. developed proprietary forging methodology for ZE62 including specific material flow analysis, tooling design and thermomechanical processing parameters that successfully retain the material’s crystalline structure and grain size.
This enables future production of high-strength forging products with exceptional performance, consistent material density and low-cost production from a range of magnesium alloys. The now documented, patented thermomechanical processing is applicable to a range of existing magnesium alloys widening the application spectrum. ALLITE® SUPER MAGTM ZE62 is designed to deliver a superior combination of tensile strength (380 MPa), yield strength (320 MPa), and elongation (more than 15%).
Weighing 30% less than aluminum by volume and being both stiffer and stronger pound for pound, ALLITE® SUPER MAGNESIUMTM has incredible potential in applications where weight, performance and efficiency are critical, particularly those where components need to be strong and ductile and have specific thermal or electrical properties while still being easy to fabricate. ALLITE® SUPER MAGNESIUMTM represents a revolutionary step forward in the field of material science and is the premier magnesium alloy being branded, positioned, and supported for mass consumer awareness.
Bioresorbable Scaffold by Magnesium Alloy Extruded Tube
Name of Part or Process: Bioresorbable Scaffold by Magnesium Alloy Extruded Tube
Magnesium tube does not include aluminum and rare earths metals. The inner diameter is 1.5~3.0 mm / Thickness : 0.11~0.30 mm / Seamless tube. All steps of casting, extrusion, drawing, laser processing, and surface treatment are carried out in-house. Our bioresorbable magnesium alloy scaffold has excellent characteristics such as biological safety (Mg alloy without rare earth), ultra thin strut (100 μm), smaller contact area for vessel wall (less than 20%) and optimum degradable property (within 1 year for disappearance. Earlier regeneration of vascular endothelialization also offered biological safety, ultra thin strut and smaller contact area for vessel walls, and offered effective abilities for the promotion of vascular endothelialization and the suppression of inflammatory reaction. The scaffold also offers the suppression of very late thrombosis. It degrades within 1 year after supporting the affected lesion for around 3 months. The property contributes to the earlier regeneration of vasomotion and the suppression of very late thrombosis. Optical coherence tomogram at 90 days after implantation in swine coronary artery shows that the shrinkage of scaffold is not serious (scaffold recoil rate: average 11%, maximum 15%), indicating that the scaffold maintains its structure. In Kumamoto, we have a consistent production system from the manufacture of the magnesium alloy base material to the final product assembly, it is possible to fabricate high-quality medical devices.
