Over the last twenty-five years the majority of non-appearance, functional plastic parts that AGS has run across are black in color. This still leaves a significant number of these parts being molded in virgin, natural plastic. This begs the question, why are some non-appearance parts molded in natural instead of black color?
Random Clues
FAQ: Does My Tooling Require Any Special Modifications to Run Injectoblend™ Recycled Plastic?
The short answer is no. There are no special tooling modifications required to mold Injectoblend™ recycled materials. A common misperception is that the shrink characteristics for virgin materials are different than their recycled equivalent. The obvious concern with a different shrink factor is the need to weld and/or re-cut the steel on the cavities and […]
Estimating Part Weights
One of the major benefits of 3D math data for component designs is the ability of CAD programs to accurately generate part volume (cm³). To calculate estimated part weight in grams using 3D CAD data multiply the calculated part volume (cm³) by the specific gravity (g/cm³) for the target plastic material.
Three Considerations to Determine Injection Molding Machine Size
1) Do the mold dimensions fit between the machine tie bar spacing and within the platen? 2) Is the machine clamp tonnage sufficient? Calculate estimated machine clamp tonnage by multiplying the part’s projected surface area by the clamping force factor for the specified plastic material. This simple calculation is a good rule of thumb, but […]
