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

Powder Metallurgy is a manufacturing process that involves creating metal parts and components from metal powders. It's a versatile technique that enables the production of intricate, complex, and high-quality parts with precise shapes and dimensions. In the powder metallurgy process, fine metal powders, typically made from iron, steel, aluminum, copper, or other metals, are compacted into a desired shape using high-pressure tooling. This compacted shape, known as a green compact, is then sintered at high temperatures in a controlled atmosphere. Ultimately, the green compact forms into a solid metal component through the bonding of metal particles during the sintering process. D&D is a Taiwan high-quality hardware manufacturer of Powder Metallurgy, 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.

Powder forming

Powder Metallurgy is a manufacturing process that involves creating metal parts and components from metal powders. It's a versatile technique that enables the production of intricate, complex, and high-quality parts with precise shapes and dimensions.

In the powder metallurgy process, fine metal powders, typically made from iron, steel, aluminum, copper, or other metals, are compacted into a desired shape using high-pressure tooling. This compacted shape, known as a green compact, is then sintered at high temperatures in a controlled atmosphere. Ultimately, the green compact forms into a solid metal component through the bonding of metal particles during the sintering process.

Powder Metallurgy offers several advantages:

Versatility in Materials: Powder Metallurgy can work with various metals and alloys, enabling the creation of components with tailored material properties suited for specific applications.

Material Efficiency: The process minimizes material waste since it starts with powdered metal. This can lead to cost savings and reduced material usage compared to traditional machining.

Cost-Effectiveness: It can be a cost-effective method for mass production of parts, especially for complex shapes, as it reduces machining time and material waste.

Consistency and Precision: It provides high precision and dimensional accuracy, resulting in consistent part quality and performance.

Some notable applications of powder metallurgy include:
Automotive, aerospace, healthcare, consumer electronics, household appliances , and components such as gears, bearings, filters, structural parts, and various specialized components.
