Compaction - The process of pressing powdered metal into a dense form before sintering. It's a critical step in powder metallurgy, producing a 'green' part that is then sintered to achieve the final properties of a powder metal part.
Custom Material Blends - Tailored material compositions developed by DSB Technologies to meet specific application requirements. This involves adjusting the chemistry and properties of powder metal materials for optimized performance.
D
Design for Additive Manufacturing (DfAM) - A design approach that optimizes part design for additive manufacturing processes, taking advantage of the unique capabilities of 3D printing technologies.
Dimensional Stability - A property indicating that a part maintains its dimensions through the manufacturing process, critical for applications requiring tight tolerances. DSB Technologies achieves this through optimized material selection and processing conditions.
E
Eject Position - In compaction press technology, the stage where the part is expelled from the press after compaction. It's a critical step ensuring the part's removal without damage.
G
Geometric Design Freedom - An advantage of additive manufacturing processes, like Metal Binder Jetting, enables the creation of complex shapes and designs, like internal structures and fine features, that are challenging or impossible to achieve with traditional manufacturing methods.
Green Part - In powder metallurgy, metal injection molding and metal binder jetting, a "green part" refers to the state of a part after compaction but before sintering. It has enough strength to be handled but has not yet reached its final density or strength.
H
High Temperature Sintering - A heat treatment process for sintered parts to bond powder together and create ready-to-use components. High temperature sintering refers to a higher sintering temperature and time at temperature, which is beneficial for stainless steels for high densification and corrosion resistance.
I
Injection Molding (3DM™ Technology) - A manufacturing process used by DSB Technologies to produce complex metal parts through injection molding with low part variability and high precision. This process is notable for its ability to achieve tight tolerances and intricate details.
Isotropic Shrinkage - Uniform shrinkage in all directions of a part during sintering, resulting in the metal part’s final design dimensions. With proprietary feedstock, DSB Technologies manufactures parts in injection molding with 50% less shrinkage than common materials.
M
Material Development - The process of creating and optimizing materials to meet specific application requirements. DSB Technologies specializes in developing custom blends and using a wide range of materials to achieve desired properties.
Metal Binder Jetting (MBJ) - An additive manufacturing process employed by DSB Technologies to produce metal parts. It involves depositing a binding agent onto layers of metal powder, which is then sintered to form solid parts. This technique is known for its ability to create parts with complex geometries.
Metal Injection Molding (MIM) - A manufacturing process utilized by DSB Technologies to produce metal components. MIM involves mixing fine metal powders with a binder material to form a feedstock, which is then injected into a mold cavity under high pressure. After molding, the binder is removed, and the resulting preform is sintered to achieve a dense metal part. This method is valued for its capability to create intricate shapes and achieve high precision in small, complex metal components. Learn More about The MIM Process
N
Net Shape -A manufacturing term for parts that are manufactured to near-final dimensions, requiring minimal finishing or machining. This term is often associated with processes like Powder Metallurgy (PM), Metal Injection Molding (MIM) and Metal Binder Jetting, where the goal is to minimize post-processing to save on time and cost.
