Conformal cooling is prevalent in moldmaking. A primary driver of conformal cooling is the ability of a cooling circuit to follow the contour of the plastic molding cavity surface, yielding consistent cooling. […]
A well-maintained (and designed) mold is the key to producing consistent, high-quality injection molded parts. Uniform cooling of the entire cavity (and uniform cooling from cavity to cavity in multi-cavity tools) will produce the highest quality parts and the fastest cycle times. Ensuring mold quality requires well-designed molds and higher precision, both of which will [...]
Changes in the industry have been dramatic, and many of those changes can be traced back to the advent of advanced simulation software to model the flow of resin within the complex runners, gates and cavities of modern high productivity molds. it’s simple have never had formal education in plastics fundamentals, because that couldn't be [...]
A well-designed injection molded part depends on many factors. The correct flow of resin into the mold is one of them. Moldflow is a professional software to simulate injection molding, which is used to simulate the flow of resin in the geometry of parts in a digital manner. The resulting data will essentially help you [...]
Designing molds with additive tooling implementation in mind requires blending traditional mold standards with innovative new ideas of what is possible to push the limits of mold performance. Additive tooling refers to the use of 3D printing (e.g. direct metal laser sintering or DMLS) to produce mold inserts out of metal, specifically tool steels, that [...]
The mold or die refers to the tooling used to produce plastic parts in molding. Traditionally injection molds have been expensive to manufacture and were only used in high-volume production applications where thousands of parts were produced. […]
The largest factor to consider when choosing the proper gate type for your application is the gate design. […]
In the molding cycle, cooling efficiency is undoubtedly a very important factor, and it’s impact on mass production is very significant, many factors impact process inconsistency. […]
If you are reading this blog, you are either a mold maker, or your job involves a major collaboration with a mold maker. I am a mold engineer. In my career, I have worked in the mold industry for more than 20 years. In these 20 years, I often talk about the importance of molds. [...]
If parts had completely uniform shrinkage, they wouldn’t warp, and they wouldn’t be injection molded. Non-uniform shrinkage exists in every part. […]
