Have you ever wondered why a magnet firmly attracts an iron bar but completely “ignores” a piece of aluminum or copper? This phenomenon originates from the magnetic properties of materials. Understanding the nature of magnetic metals is not only practical knowledge but also a critical foundation for engineers to select the right measurement equipment in manufacturing and quality control.

On February 26th, the gold market reached its peak as the God of Wealth Day (the 10th day of the first lunar month) is always considered the time of year when most people buy gold. From early morning, the number of customers on gold trading streets increased rapidly compared to normal days. Some bought gold for good luck at the beginning of the year, while others took advantage of the opportunity to hoard it with spare money after Tet.

In precision mechanical processing, tapping might seem like a simple step, but it directly affects connection durability and structural safety. Even a minor error during the tapping process can result in threads not achieving the desired fit, leading to loose bolts or an inability to tighten them properly. Loose thread quality has thus become a common issue, even for experienced technicians.

The packaging and printing industry is one of the sectors most heavily affected by static electricity. The unwanted accumulation of electrical charges on materials such as paper, plastic, BOPP film, and PET can reduce production efficiency, increase defect rates, and even pose fire and explosion risks. To effectively eliminate these issues, specialized static elimination (ionizing) devices must be implemented.

In today’s increasingly complex supply chain environment, effective inventory management has become a top priority for every business. In particular, Zebra handheld inventory scanners from Zebra Technologies are widely trusted thanks to their outstanding advantages and reliable performance.
