What is the difference between metal injection molding and casting?

Although there are some variations in technique, the major difference between die casting and metal injection molding is that die casting uses some kind of metal, often an aluminum alloy or zinc alloy, as the raw material, while metal injection molding uses steel or other types of MIM alloys.

What is an action in injection molding?

Actions are special features designed into a mold that allow molding of undercut features, but retract to also allow straight ejection of the part.

What is the difference between injection molding and extrusion?

Injection molding is suitable for three-dimensional product manufacturing whereas extrusion molding is only suitable for two-dimensional product manufacturing. Injection molding is the oldest plastic manufacturing process whereas extrusion is comparatively new. Atypical cross-sections can be achieved by extrusion.

What is MIM process?

Metal injection molding (MIM) is a metalworking process in which finely-powdered metal is mixed with binder material to create a feedstock. The feedstock is then solidified and shaped to produce the final product.

What is cavity and core?

The core & cavity are the shaped sections in either half of the mould tool which give the plastic product its final shape. The hot molten material is injected into the core & cavity and then sets hard into shape. The design of the core & cavity is essential in the correct formation of the product.

What are the advantages of injection Moulding?

Injection moulding advantages:

• Efficient high production. Once you have developed the moulds, the process is extremely fast with cycle times as short as 10 seconds.
• Low cost per part.
• Repeatability.
• Large material choice.
• Low waste.
• High detail.
• Little or no post processing.
• Initial cost.

Is injection molding continuous?

Injection molding is a continuous process for the production of three-dimensional objects with a cavity, such as the jars that contain yogurt and the capsules used for coffee powder, both of which are made of PP.
