[China Aluminum Industry Network] 1. One of the things that caused us headaches in the mold making process was that after finishing most of the processing operations, we suddenly discovered that sand holes or unknown grains appeared on the finished polishing surface. Retire the workpiece.
A: The unique grain refinement process guarantees that all aerospace product series will pass the ultrasonic flaw detection procedure for aerospace aluminum alloy products without sand holes, horizontal stripes, bubbles and impurities. Excellent heat treatment technology, product below 300mm thickness (or diameter), strength, hardness can be consistent. All production processes are controlled by the computer, with few artificial deviations, and different batches of production can guarantee the same performance.
2. Our products are electronic manipulators and electronic tooling boards. The aluminum parts can not be deformed a little after being processed. Why are the European or domestic boards that we previously bought on the market suddenly deformed one or two days after processing?
A: The perfect pre-stretching internal stress elimination process completely eliminates the internal stress, and the product will not warp, crack or deform when processed or subjected to stress.
3. Our products are used for mechanical structural parts, which require that the strength of aluminum parts is stable and consistent, and that they will not undergo fracture deformation at a certain point.

4. When processing precision workpieces, we require that the thickness and tolerances are very accurate. If the tolerances are not uniform, self-correction will not only increase the cost, but will not waste time, and sometimes it will make the workpiece obsolete.
A: All products comply with the American Society of Materials and Testing (ASTM) and Aerospace Materials Specification (AMS). The tolerances of most products can exceed the ASTM1/2 tolerance accuracy, and some product tolerances can even exceed the ASTM 1/4 standard tolerances. .
5. We are a hardware processing factory. In the past, we often encountered "sticking knife" and "broken knife" when processing aluminum parts, resulting in low surface finish and dimensional accuracy of the workpiece, and a high scrap rate.
A: All products comply with the American Society of Materials and Testing (ASTM) and Aerospace Materials Specification (AMS). The tolerances of most products can exceed the ASTM1/2 tolerance accuracy, and some product tolerances can even exceed the ASTM 1/4 standard tolerances. .
The deviation of chemical composition, strength and hardness is reduced to a small extent, and the phenomenon of “sticking knife†or “broken knife†does not occur during processing.
Excellent heat treatment technology, product below 300mm thickness (or diameter), strength, hardness can be consistent.
6.Our products are all made of aluminum alloys. In the production process, we find the difficult problem is that the quality of previously purchased aluminum alloys is not stable. It can be used during trials, and changes in use. Sometimes the quality of the same batch of aluminum is also different. Very large, making the production process difficult to adapt. Product quality is also difficult to guarantee.
Answer: All the production processes are controlled by the computer. There is little artificial deviation. Different batches of production can guarantee the same performance.
7. Does our aluminum workpiece require uninterrupted or intermittent operation at a high temperature of 300-500°C, can Alcoa meet the requirements?
A: Excellent heat treatment technology, the product is less than 300mm thickness (or diameter), the strength and hardness can be consistent.
In the working environment of 400 °C will not produce longer deformation.
8. Our products have a bending process during the manufacturing process and require no cracks or fine lines on the bends of the aluminum parts.
Answer: All the plates pass the semi-conducting bend test, and they will not crack when they are bent 180 degrees.
9. The aluminum plate that we need is the platen used on precision machinery. It requires a beautiful coloring effect. Can Alcoa meet this requirement.
A: The color effect on the aluminum plate is determined by the three elements of the lattice structure arrangement, the organization density and the heat treatment process technology. Alcoa's production technology is superb, its chemical composition is controlled accurately, and its inspection procedures are complete, which guarantees Alcoa's excellent quality.
Caster wheels is one kinds of wheel with bracket, it could be fixed to your workbench, equipment, handle cart, trash bin, dustbin, or other large object, then you can move them easily to save labor and time. Caster's main material could be rubber, nylon, PU, PF, PP, TPR...etc. Rubber and TPR is soft and elastic, this makes pull or push much easier, besides the rubber eliminates most noise, and could protect your floor well avoid damage floor, so then rubber caster specially suit indoor places.
The caster normally includes metal (steel, stainless steel) or nylon bracket, rubber wheel, wheel core (PP, steel, aluminum, nylon), bearing, and bolts parts. To fit with different weight or size objects, there are various diameters, widths casters, various thick brackets, the bigger the heavier rubber caster could load.
Now, we can provide normal rubber caster, anti-static rubber caster, dustbin caster, platform hand cart caster...etc.
