Cold Drawing
Cold drawing is a critical metalworking process that involves pulling a material through a single, or a series of, progressively smaller dies at room temperature (or slightly elevated, but below its recrystallization point). This process is primarily used to shape and form metal, but it can also be applied to plastics and other materials. The primary goals are […]
Effects of Quenching on Metal Properties
The main reason for quenching is to enhance hardness and strength. When you heat your material to the critical temperature, partial or complete austenizing takes place. However, due to rapid cooling, austenite is prevented from transforming into ferrite or pearlite. Instead, it is changed into martensite, resulting in a metal that is very hard […]
Core Mechanisms of Annealing Works
Processes like casting or bending can often affect the structure. So, annealing is used to fix these small defects and align the structure. Three key changes happen during this process: Atomic Migration: Heat gives the atoms energy, allowing them to move around and rearrange into a more orderly pattern. Dislocation Reduction: Dislocations are […]
Materials Used in Sand Casting
Sand casting is one of the most versatile and widely used metal casting processes. Its key advantage is its ability to cast a enormous range of metals and alloys, from common iron to high-performance superalloys. The choice of material depends on the required properties of the final part, such as strength, weight, corrosion resistance, machinability, […]
Essential Elements of a Custom Metal Part Production Drawing
A production drawing (also known as a mechanical engineering drawing or blueprint) is the universal language between designers and manufacturers. For custom metal parts, clarity, completeness, and precision are paramount to avoid costly errors and delays. Here are the critical elements it must contain: 1. Title Block This is located in the bottom right corner of […]
Heat Treatment Equipment and Technology
Most factories use special equipment and tools to control the heat treatment processes. Furnaces There are different kinds of furnaces used in the heat treatment process. Batch furnaces are used to treat one load at a time, and it is best used for small parts. Continuous furnaces keep the moving parts through a long […]
Materials Suitable for Forging
Forging is a manufacturing process where metal is shaped using localized compressive forces, typically from a hammer or die. This process aligns the metal’s grain flow, enhancing its strength, toughness, and structural integrity. A wide range of materials can be forged, each chosen for specific mechanical properties and application requirements. The materials are broadly categorized […]
Benefits of Heat Treatment
There are many advantages you get when heat treating metals, such as: The process improves the mechanical properties of metals, making them last much longer under stress. It also makes it easier to work with metals by making them softer through processes such as annealing. Hard metals also hold edges for a longer […]
Welding Technology
Welding is a fundamental fabrication process that joins materials, typically metals or thermoplastics, by causing coalescence. This is most often done by melting the workpieces and adding a filler material to form a pool of molten material that cools to become a strong joint. It is distinct from lower-temperature techniques like brazing and soldering, which […]
Does Rust Preventative Oil Affect Welding?
Yes, absolutely. Rust preventative oils have a significantly negative and often dangerous impact on the welding process and the quality of the finished weld. Using oil-coated parts for welding is considered very poor practice and is strictly avoided by professional welders. Here’s a detailed breakdown of why and how it affects welding: 1. Formation of Weld […]
