What are core pins?
Core pins are used in the plastic molding and die casting dies. They are a fixed element used to create a void providing the desired shape in the molded or cast part. It is often easier to machine a core pin as a separate element and add it to the A-side or B-side as needed.
How do you measure injection mold size?
Most injection molders will recommend 2.5 times the surface square inches of the part and an additional 10% as a safety factor. If you have a part that is 120 square inches, you would need a press size with 300 tons of pressure.

Why is rapid prototyping called Rapid?
It's a fast way of fabricating physical parts or whole models using digital 3D modeling and additive manufacturing. It's called “rapid” because it's much faster than other types of prototyping, especially the ones involving injection molding, allowing to test and evaluate engineered products.
Why should prototyping be rapid and cheap?
It is inexpensive and fast.
While other prototyping methods can be costly or slow, rapid prototyping is all about cheap materials and quick turnaround time. Rapid prototyping doesn't require much labor, time, or money, which means that anything you learn from this testing method will be worthwhile.
Why RP is called as additive manufacturing?
Additive manufacturing refers to any manufacturing process which makes products by gradually adding materials. Rapid prototyping is usually achieved by additive manufacturing process.
What is the difference between rapid tooling and rapid prototyping?
Rapid tooling (RT) and rapid prototyping (RP) is any method or technology that enables one to produce a tool or product quickly. The term rapid tooling refers to RT-driven tooling. A prototype is a 3-D model suitable for use in the preliminary testing and evaluation of a mold, die or product.
What is the unit of injection rate?
The performance of an injecting unit is expressed by the injection rate (the volume of molten plastic that is injected in one second, cm3/s) or the injection speed (the speed of forward movement of the plunger, mm/s).
