In recent developments, the National Automobile Electrical Standardization Technical Committee has finalized and is now seeking opinions on five key industry standards. These include "Technical Conditions for Power Window Switches in Vehicles," "Technical Conditions for Electromagnetic Clutches in Automotive Air Conditioners," "Technical Conditions for Motors for Window and Window Lifters," "Technical Conditions for Electric Window Anti-Clamp Electronic Modules," and "Technical Conditions for Combination Switches on Steering Columns for Automobiles." These documents are expected to be officially released after final expert discussions.
Among these, three standards specifically target the electric window market. They cover the technical requirements for power window switches, motors for window lifters, and anti-clamp electronic modules. This marks the first time an industry standard related to electric windows has been developed in years, as previous standards in this area were non-existent. The adoption of electric windows has significantly improved user experience, replacing manual mechanisms with motor-driven systems that make operation more convenient and comfortable. A few years ago, electric windows were considered a luxury feature, but today they are a common standard in most vehicles.
However, with their widespread use, challenges such as safety, durability, and the anti-clamping function have emerged. Reports of consumers being injured by electric windows have raised concerns. Due to the absence of industry standards, the market for electric window components has remained unregulated, with inconsistent quality and testing procedures among manufacturers. Many products entered the market without proper certification, leading to low entry barriers and poor quality control.
To address these issues, the National Development and Reform Commission initiated the development of industry standards last year, with the National Automobile Electrical Standardization Technical Committee overseeing the drafting process. Experts involved in creating these standards emphasize that the new guidelines comprehensively cover technical specifications, testing methods, and inspection rules. They also incorporate international best practices while considering domestic needs and future technological advancements.
The revised "Technical Conditions for Combination Switches on Steering Columns for Automobiles" updates the 1996 version, reflecting the increasing integration of electronic modules in modern vehicle steering columns. As automotive technology evolves, combination switches have become more complex, requiring updated standards to ensure compatibility and performance.
Additionally, the newly introduced "Technical Conditions for Electromagnetic Clutches for Automotive Air Conditioners" addresses a long-standing gap in the industry. With no unified standard for electromagnetic clutches, manufacturers and users faced difficulties in evaluating product performance. This new standard aims to improve quality control, provide a basis for production and testing, and promote industry-wide technical advancement.
Overall, the introduction of these standards represents a significant step toward better regulation, quality assurance, and consumer protection in the automotive electrical sector.
METAL 3D Printing - SLM / DMLS
Metal 3D Printing - Slm / Dmls
METAL 3D Printing - SLM / DMLS
The two technologies have many similarities: both use laser scanning and selectively fuse (or melt) metal powder particles, glue them together and build them layer by layer. Similarly, the materials used in both processes are granular metals.
The difference between SLM and DMLS is due to the basis (and patents) of the particle bonding process: SLM uses metal powder with a single melting temperature and completely melts the particles, while in DMLS, the powder is composed of materials with variable melting points at high temperatures Fusion at the molecular level.
