A Screw thread is a spiral ridge that wraps around a screw. It is the thread that makes the srew a screw. A screw thread

Have you ever wondered how manufacturing can be so precise and repeatable? The explanation for this isn’t just the high-tech machines, but also the tooling behind them.

Making threads is perhaps one of the fundamental things you do in the workshop now and then. For a long time, threading was the method

Riveting and welding are the two most common metal joining processes today. Each method has unique characteristics and applications. Let’s dive into the specifics of

So, you have a project that involves metal forming. You might be examining a flat piece of sheet metal and saying, “How do I make

In manufacturing, producing a perfect part is not just about creating the correct shape; it’s about producing a perfect surface. Consider a car’s engine cylinder,

Among most modern industrial manufacturing techniques, electrical discharge machining stands out due to its high precision and minimal wear or tear on the target material.

Have you ever picked up a book with a shimmering, metallic title that catches the light just right, or a luxurious perfume package with a

Have you ever seen a shiny new metal appliance or an area of outdoor furniture and thought about how incredible it was to have such

There are different types of polishing for different materials. The polishing types include mechanical polishing, chemical polishing, electropolishing, and nano polishing. These polishing methods refine

Introduction Not meeting the desired aesthetic or functional standards? It could be due to poor surface finish, which can adversely impact both the visual appeal

If you’ve ever run your finger across a machined part and noticed how smooth—or not—it felt, you’ve already encountered surface roughness. It’s basically how much the

Have you ever thought about why stainless steel looks so clean? It’s a great material: robust and has a beautiful surface. But it’s not completely

Surface finishing is a manufacturing process where the surface of a product is altered to achieve certain qualities. Surface finishing is done to enhance the

Shot blasting has been helpful to many industries since the first machine was used in the 1900s. This was because manufacturers sought to have better

Surface finishing enhances metal parts by improving corrosion resistance, wear resistance, and aesthetics in industries like aerospace, automotive, and electronics. Anodizing and electroplating, two widely

In the industrial setting, it is common to subject materials to coating. Manufacturers do this to not only enhance the aesthetic appeal but also to

Anodizing is the oxidation of a metal in an electrolyte, resulting in the formation of an oxide coating on the metal surface. It is one of the

Have you ever seen those really shiny bathroom fixtures or car bumpers? That’s chrome plating in action! Recent Google search trends show that interest in

Before a product is mass produced, manufacturers love to test their products and conduct market surveys. They therefore, need small batches of prototypes and sample

CNC precision machining is a vital process that is widely used in the manufacturing industry to produce components with exceptional accuracy that meet the highest quality

CNC turning is a subtractive manufacturing process that relies on computer numerical control (CNC) to machine parts and components. The process involves rotating a workpiece

At ZongHong Tech, we use 5-axis machines every day. They are ideal for prototyping, especially when customers require tight tolerances or unusual angles. And with

What is 3-axis machining? So, what exactly is 3-axis machining? We can think of it as the foundation of most machining processes: a milling machine.

Who We Are? We are a professional CNC machining and rapid prototyping factory located in Shenzhen, the core area of ​​precision manufacturing in China. Established
