• What are the technical considerations for anodizing aluminum ？

  Jul 18, 2025

  1. Anodizing tank setup: The electrolytic cell is responsible for the entire electrolysis process and it is where the aluminum and cathode are immersed in the electrolytic cell. The electrolytic cell is usually made of chemically resistant materials such as polypropylene, PVC or coated stainless steel. To fix the anodes, the electrolytic cell comprises a rack mechanism which is further connected to the electrical busbar for a uniform and controllable power supply. On the other hand, a separ...

• How does the anodizing process work ？

  Jul 03, 2025

  1. Preparation and cleaning: A uniform and smooth surface is essential for the application of the anodized layer. You can achieve this through mechanical treatment and chemical cleaning. Mechanical surface treatment such as grinding and polishing that remove surface irregularities and defects. While alkaline or acid cleaning removes grease, oil, dirt and any other contaminants, followed by rinsing with deionized water to remove residual cleaning agents. Therefore, etching can be furthe...

• What is anodizing ?

  Jul 03, 2025

  Anodizing is a surface treatment method that forms a thin protective oxide layer on the surface of the substrate through an electrochemical process to achieve a smooth and uniform surface treatment, with a roughness value (Ra) as low as 0.5µm. Anodizing can improve the firmness, corrosion resistance, wear resistance and aesthetics of aluminum alloy, magnesium alloy and titanium alloy accessories. Anodizing has a wide range of applications and is widely used in various industries such as me...

• Application of aluminum extrusion profiles in the automotive machined parts industry

  Apr 21, 2025

  1.Aluminum extrusion profiles have high cross-sectional dimensional precision and have different precision due to different production processes. For high vacuum die-casting structural parts, the dimensional deviation is usually large due to the shrinkage and deformation caused by heat treatment of the castings, and the large deviation can reach 1~3mm. For aluminum extrusion profiles processes, the cross-sectional dimensional accuracy is generally higher, the dimensions are more stable and easie...

• What are the kinds of anodizing aluminum？

  Apr 21, 2025

  There are four types of anodizing processes based on the acid bath type and thickness capabilities. Chromic Acid Anodizing (Type I) Type I is the ideal if you need a thin layer, especially for decorative and some functional uses. However, it can mimic the performance of Type II or hard coating after sealing. Meanwhile, the thickness of the layer ranges from 0.00002"-0.0001".    Sulfuric Acid Anodizing (Type II) This is the most common type and uses sulfuric acid as an electrochemi...

• Our advantage:Steel ball assembly process for Miniature Ball Screws

  Mar 10, 2025

  The steel balls are assembled in units of 1 μm as it is a precision component. There will be some tolerances in screw grinding and nut grinding. It is the most undesirable method to assemble the Miniature Ball Screwscrew and nut separately and assemble them directly after processing. The screw and nut need a suitable steel ball gauge to match. The directly assembly method will have the human factors, and it is difficult to control the assembly preload to be consistent. Each of our nuts and th...

• Our advantage:Alignment process for Ball Screws

  Mar 10, 2025

  The Ball Screws must be aligned before assembly to control the runout. It is calibrated to the corresponding runout value according to the accuracy level of the Ball Screws. The hydraulic and servo alignment processes are both cold alignment processes and It is qualified only if it jumps when shipped. As time goes by and the stress is released during transportation bumps, the Ball Screws will slowly rebound to the state before straightening.  We use a thermal alignment process to internally...

• Our advantage:Material pre-processing of Linear Actuator parts

  Feb 27, 2025

  The Linear Actuator parts material and heat treatment are the basic guarantees for high-quality Ball Screws and Planetary Roller Screw. We obey the superior alloy steel and the molding process must be spraying, not casting. Strictly required to use a two-ball, two-draw process, and the eutectic carbide must reach level 1 for Ball Screws Assemblies. After the materials need to be undergone a cold pressing process similar to "forging" to further optimize the metallographic structure. The cold...

• Our advantage:Thread Rolling Machine for Roller Screw Actuators

  Feb 27, 2025

  The cold-rolled screw rolling machine is a key for manufacturing Ball Screws and Planetary Roller Screw.Most manufacturers use "dovetail rail" structure thread rolling machine. The "dovetail rail" needs to be added with "shims" to adjust the matching clearance. The defect is it cannot be pushed axially if it is locked, and there will be radial deflection if the lock is loose, the Ball Screws Assemblies will have "black and white circles", the Ball Screws will have inconsistent contours and round...
