What is Injection Molding?

November 9, 2022

[vc_row][vc_column][vc_column_text]Injection molding is a process of shaping plastic by melting it and injecting it into a predesigned mold. The process was first designed in the 1930s and was originally based on metal die casting designs. It offers many advantages to alternative manufacturing methods, including minimal losses from scrap (since scrap pieces can be melted and recycled), and minimal finishing requirements. This process differs from metal die casting in that molten...

How to Get Rid of Bubbles in Injection Molding

November 7, 2022

[vc_row][vc_column][vc_column_text]One of the top causes of cosmetic rejects in molded parts is bubbles. This troublesome part defect not only results in appearance problems but impairs physical properties as well. Bubbles are a common occurrence and are often difficult to resolve. In troubleshooting bubbles, many molders make the mistake of guessing at what the bubbles are, and then immediately start adjusting process parameters to eliminate them. I urge you to resist...

What Is Rapid Prototyping?

October 12, 2022

[vc_row][vc_column][vc_column_text]What Is Rapid Prototyping? Rapid prototyping is a technology that takes a three-dimensional computer model and builds a three-dimensional part by building layers upon layers of material. Its speed and low cost allow design teams to confirm their new designs early and frequently in the process. Step 1 Start with a 3-dimensional computer model. Typically, they are created in 3D CAD products like Solid Works, Rhino, Pro/E, Mechanical Desktop, etc....

Injection Molding: How to Set Second-Stage (Pack & Hold) Pressure

October 10, 2022

[vc_row][vc_column][vc_column_text]With Scientific Molding, two stages are used for forming the part: The first stage for getting most of the plastic into the part, normally 90% to 99.9% full by volume; and the second stage, to pack the part to replicate the steel cavity texture and shape. The second stage usually moves relatively little plastic in the cavity but it is critically important for surface finish, cosmetics, and part dimensions. Most...

What Is Prototype Tooling?

October 5, 2022

[vc_row][vc_column][vc_column_text]Prototype tooling is a way of creating a prototype from a design or three-dimensional (3D) model; in many regards, it is the same as regular tooling. Traditional tooling techniques usually are used with prototype tooling, but 3D printing also can be used to form the prototype for some needs. While this is similar to regular tooling, there are differences in how the prototype is put together and its overall functionality....

Hot/Cold Injection Molding: Which Approach Is Best for You?

August 10, 2022

[vc_row][vc_column][vc_column_text]Despite the many advances in injection molding technology, challenges remain in producing visually acceptable parts with high esthetic requirements, free of molded-in stress, and with high dimensional stability, as well as reliably filling thin walls with high flow lengths. In the early 2000s, several Japanese companies collaborated in developing a molding technology that could satisfy the most stringent surface-quality requirements of their demanding electronic consumer-goods clients. In 2002, Ono Sangyo...

Casting grade of polyurethane can be injection-molded

August 3, 2022

[vc_row][vc_column][vc_column_text]Adiprene C930, a low free methylene diphenyl diisocyanate (MDI) -based cast urethane from Lanxess, has been proven as an appropriate material for being processed via injection molding. Korean company Autox developed a production process that allows the cast polyurethane grade to be injection-molded. This innovation brings a new perspective to the cast polyurethane (CPU) world as it combines the processing advantages of injection molding along with the properties of cast...

Injection Molding: Focus on these Seven Areas to Set a Preventive Maintenance Schedule

August 1, 2022

[vc_row][vc_column][vc_column_text]It is impossible to mold parts without a working injection machine. This is something that molders can state with absolute clarity. Yet, there are still many companies that follow a “run-parts-until-the-machine-breaks-down” approach. The question we must ask ourselves is why? Unplanned maintenance is costly. In these instances, the discussion and development of repair plans occurs with the press sitting idle. Replacement parts need to be located, assuming they are in-house...
