About Cabling Installation & Maintenance

Our mission: Bringing practical business and technical intelligence to today's structured cabling professionals

For more than 30 years, Cabling Installation & Maintenance has provided useful, practical information to professionals responsible for the specification, design, installation and management of structured cabling systems serving enterprise, data center and other environments. These professionals are challenged to stay informed of constantly evolving standards, system-design and installation approaches, product and system capabilities, technologies, as well as applications that rely on high-performance structured cabling systems. Our editors synthesize these complex issues into multiple information products. This portfolio of information products provides concrete detail that improves the efficiency of day-to-day operations, and equips cabling professionals with the perspective that enables strategic planning for networks’ optimum long-term performance.

Throughout our annual magazine, weekly email newsletters and 24/7/365 website, Cabling Installation & Maintenance digs into the essential topics our audience focuses on.

  • Design, Installation and Testing: We explain the bottom-up design of cabling systems, from case histories of actual projects to solutions for specific problems or aspects of the design process. We also look at specific installations using a case-history approach to highlight challenging problems, solutions and unique features. Additionally, we examine evolving test-and-measurement technologies and techniques designed to address the standards-governed and practical-use performance requirements of cabling systems.
  • Technology: We evaluate product innovations and technology trends as they impact a particular product class through interviews with manufacturers, installers and users, as well as contributed articles from subject-matter experts.
  • Data Center: Cabling Installation & Maintenance takes an in-depth look at design and installation workmanship issues as well as the unique technology being deployed specifically for data centers.
  • Physical Security: Focusing on the areas in which security and IT—and the infrastructure for both—interlock and overlap, we pay specific attention to Internet Protocol’s influence over the development of security applications.
  • Standards: Tracking the activities of North American and international standards-making organizations, we provide updates on specifications that are in-progress, looking forward to how they will affect cabling-system design and installation. We also produce articles explaining the practical aspects of designing and installing cabling systems in accordance with the specifications of established standards.

What are the working processes of a green sand molding machine?

The working process of a green sand molding machine mainly includes the following steps, combined with the sand molding technology in casting processes:

1、Sand Preparation‌

Use new or recycled sand as the base material, adding binders (such as clay, resin, etc.) and curing agents in specific proportions. For example, in resin sand processes, recycled sand requires 1-2% resin and 55-65% curing agent, while new sand needs 2-3% resin.Control sand performance parameters, including strength (6-8 kg•f), moisture content (≤25%), and clay content (≤1%).

2、Mold Preparation‌

Inspect the mold (pattern or core box) for flatness, movable blocks, and locating pins. Apply mold release agent to ensure smooth demolding.Install auxiliary components such as gating systems and chills, and clean them of rust or sand adhesion.

3、Sand Filling and Compaction‌

Pour the mixed sand into the flask or core box, discarding the initial batch to ensure uniform curing.Compact the sand mechanically or manually to eliminate loose areas, then level the surface.

4、Venting‌

Use venting needles to create air vents in the sand mold. The depth of vents in the upper mold should be 30-40 mm from the mold surface, while the lower mold requires 50-70 mm to prevent molten metal leakage.

5、Mold Assembly and Pouring‌

Combine the upper and lower molds to form a complete casting cavity.Pour molten metal, which solidifies into the rough casting after cooling.

6、Post-Treatment‌

Remove sand from the casting, clean the workpiece, and perform heat treatment or inspection.

The workflow of a green sand molding machine is similar to manual molding but improves efficiency and consistency through mechanization, making it suitable for mass production. Specific process parameters (such as sand temperature and resin dosage) must be adjusted based on production conditions.
