Getting the Most Out of Injection Molding Simulation
2023年7月13日 · How Front-End Simulation Alleviates the Challenges of Plastic Injection Mold Design. — Christopher Blake, Maya HTT; Learn more about Molding 2023, which will be collocating with MoldMaking Technology magazine’s MoldMaking Conference (registrants to either event can attend both), including speakers addressing sustainability and automation.
Novel Nozzle Tip Prevents Stringing, Saving Molds & Cycle Time
2020年10月12日 · If they hang over the parting line, those thin strings of plastic will hob the mold—even a heat-treated steel tool—eventually leading to flashing. Fattori says that can’t be fixed properly by simply grinding the parting line—it requires an extensive mold rebuild, “all because of a $20 nozzle tip.”

Part 1: How to Properly Size Gates, Runners and Sprues
2020年3月26日 · The point I am making here is, if you’re injecting 14.1 in. 3 /sec of material into a mold, don’t think the material is going into each cavity of a multi-cavity mold at the same 14.1 in. 3 /sec. In fact, for a 32-cavity mold, the flow rate in this example drops down to 0.45 in. 3 /sec. There is a direct correlation between the number of ...
A New Look at Evaluating Fill Times For Injection Molding
2013年7月29日 · 1. Using maximum injection velocity, adjust shot size to get the fullest part 95% full. 2. Record the fill time and pressure at transfer. 3. Reduce injection velocity and record the fill time and pressure at transfer. 4. Repeat Step 3 until the fill time is over 10 sec. 5. Use the data to calculate relative shear rates and relative viscosities:
Take a Look at Vision Mold Protection | Plastics Technology
2012年11月28日 · Some are familiar to injection molders and others are little known and little utilized. The most typical types of mold protection are low-velocity, low-pressure clamp-closing settings on the injection molding machine and external sensors like pressure sensors on robot end-of-arm tooling (EOAT) or noncontact sensors for detecting parts in the mold.

Avoid Common Mold Set-Up Mistakes | Plastics Technology
2003年7月1日 · Donnelly has 27 injection presses from 28 to 720 tons, executes an average of 30 (and as many as 55) mold changes a day, and usually performs from 190 to 210 set-ups weekly. Some production runs can be as short as 15 min, although a 10-hr run is the average.
Avoiding Common Cosmetic Defects in Molded Parts
2023年12月8日 · Injection-molded part aesthetics start with draft. Sufficient draft is an important part of any mold design, even with quick-turn tooling. Vertical walls, meaning those part surfaces parallel to the direction of mold operation, should have a minimum draft angle of a 1 / 2 degree, though 2 degrees is even better. Heavily textured surfaces may ...
