D&D BUILDERS HARDWARE CO. - D&D Builders Hardware Co. is a door closer and hardware manufacturer in Taiwan, produces hardware for doors and windows.

Forging | Your Trusted Source for Electromagnetic Locks & Access Control Systems | D&D Builders Hardware Co.

Forging is a manufacturing process where metal is shaped through the application of pressure, typically using a hammer or a press. Due to the continuous grain flow and absence of porosity, forged parts exhibit exceptional strength, toughness and structural integrity.The process can be performed at room temperature (cold forging) or at elevated temperatures (hot forging), depending on the material and desired properties of the final product. Key aspects of the forging process include: heating (for hot forging), shaping, Open-Die forging or Closed-Die forging and finishing. D&D is a Taiwan high-quality hardware manufacturer of Forging, SLIDE back Sliding Door Closer, Self-Closing Door Closer, Deadlock, Exit Device, Glass Fitting, Deadlatche, Electromagnetic Lock, Floor Spring, Panic Device, Panic Bar, Deadbolt since 2002. We have extensive and rich metal processing, plastic and rubber processing experience, such as: stamping, casting, die casting, forging, extrusion, CNC turning parts, Machining parts, plastic injection, rubber compression, transfer molding and injection molding. With more than 20 years experience, D&D is specialized in handling OEM projects and various industrial processes, such as designing, molding, plastic injection, rubber injection, metal machining, stamping, deep drawing pressing, forging, die casting, powder metallurgy, CNC machining and related fabrications.

Forging is a manufacturing process where metal is shaped through the application of pressure, typically using a hammer or a press. Due to the continuous grain flow and absence of porosity, forged parts exhibit exceptional strength, toughness and structural integrity.

The process can be performed at room temperature (cold forging) or at elevated temperatures (hot forging), depending on the material and desired properties of the final product. Key aspects of the forging process include: heating (for hot forging), shaping, Open-Die forging or Closed-Die forging and finishing.

In addition to superior strength and durability, other significant advantages that forging offers are:

Enhanced Mechanical and Metallurgical Properties: The forging process refines the internal grain structure of the metal, improving mechanical properties such as increased tensile strength, impact resistance, and better metallurgical properties compared to cast or machined parts. At the same time, it reduces internal voids, gas pockets, and inconsistencies in the material.

Consistent and Uniform Structure: The forging process creates a more uniform and consistent grain structure throughout the part. This uniformity minimizes material inconsistencies and weak spots, contributing to the part's reliability and longevity.

Resistance to Fatigue and Stress: The directed grain flow and absence of internal defects reduce stress concentrations within the material. This property makes forged parts more resistant to fatigue failure, ensuring continued performance under repeated stress and load conditions.

Flexibility in Material Choices: Forging is suitable for various metals and alloys, including steel, aluminum, titanium, and exotic alloys, allowing flexibility in material selection based on the application requirements.

Variety of Shapes and Sizes: The process accommodates a wide range of part sizes and shapes, from small intricate components to large and complex shapes used in critical applications.

Due to the ability to produce strong, durable, and high-quality metal components, forging is especially suitable for critical industries such as:
Oil and gas industry, heavy machinery and equipment, power generation and railway and transportation.
