What is the Surface Treatment of Custom Keyboard Case

Surface treatment is the last part of the production process of customized aluminum alloy notebook case. The surface treatment can not only bring beautiful appearance to the product, but also improve the use performance of the product. If you want to have a precise aluminum shell with beautiful, delicate, smooth and textured appearance, the surface treatment process is essential. Some people asked what is the specific process of surface treatment and what is its purpose? What is the process? Now, here’s CNCJY’s summary. We also mentioned 4 key factors to improve the quality of keyboard case customization.

Surface Treatment of Customized Keyboard Case

Surface treatment is the process of manually forming the mechanical, physical and chemical properties and other surfaces of the case on the surface of the customized aluminum alloy notebook case. The purpose of surface treatment is to meet the requirements of abrasion resistance, corrosion resistance, decorative shape or other special functions of aluminum alloy shell. For aluminum shell, surface treatment can be divided into four aspects:

1. Machine surface treatment: Polishing, sandblasting, spraying, drawing, layout, rolling.

2. Chemical surface treatment: Acid cleaning, alkaline, blue blackening, chemical oxidation.

3. Electrochemical surface treatment: Anodizing, electroplating.

4. Modern surface treatment: Laser carving, ion plating.

4 Key Factors to Improve the Quality of Keyboard Case Customization

Due to market competition, under the new situation of “survival by quality”, keyboard shell customization enterprises should not only strictly control the service, but also pay attention to the quality control of good product samples and product shipments. The customized production of aluminum alloy shell is a very complex process, so it is impossible to absolutely prohibit the production of unqualified products, so the inspection of products is very important. What is the function of quality inspection?

1. Check Function
Through the raw material, keyboard case, customize the factory’s processing, product delivery and other links to carry out quality inspection, and control the flow of defective products layer by layer. Strictly implement various technical standards and inspection procedures, strictly put unqualified raw materials into production, flow unqualified semi-finished products into the next process, and strictly implement the process checkpoints such as unqualified product factory. Order quantity of aluminum alloy case: In large order production, integrate the process as much as possible, use composite CNC machining or skip CNC machining to maximize production efficiency and reduce production costs. In small and medium-sized order production, simple mold CNC processing can be used to reduce mold manufacturing costs.

2. Prevention Function
Through the first inspection of aluminum shell in each process, each team leader should find out the quality problems caused by operation, clamping, processing procedures, drawings, etc. as early as possible through daily patrol, and take measures to reduce the occurrence of more nonconforming products. Requirements for customized dimension accuracy of keyboard shell; If the dimensional accuracy is high, some auxiliary processes can be added appropriately to ensure the product accuracy and reduce scrap.

3. Supervision Function
Quality inspection is an indispensable technical supervision in the customized production process of aluminum shell. Violate the process and operation process, transfer to the next process without checking the nonconforming products, and supervise the received balance of nonconforming products. The existing mould making conditions and CNC processing equipment of the enterprise are too complex. The mould making and assembly is a great test to the enterprise’s mould making conditions.

4. Feedback Function and Quality Detection
The inspector shall timely sort out, count, analyze, judge and provide product quality information feedback to enterprise leaders and relevant departments according to the quality and process conditions. It provides a timely and effective information base for product design improvement, process improvement and operation mode improvement. Production stability of aluminum shell mold; Factors that affect the stability of the mold (such as mold material, mold component accuracy, lubrication conditions, etc.) can be appropriately added when determining the number of processes to prevent extreme deformation during CNC machining, thus effectively improving the stability of CNC machining process.
