Hold Vacuum on Steel Mold Cavity
Customer manufactures plastic injection molded parts in aluminum and steel molds. If the molten plastic does not completely fill the mold, then the resulting part is flawed and thus rejected. The smaller the mold cavities are, the harder they are to fill completely. One particular steel mold has a 1-2 cubic inch cavity that they were having considerable trouble getting it to fill consistently. Thus, they were looking for a way to pull a vacuum on this cavity to help alleviate the problem. Because steel is an essentially non-porous material, and because of the small size of the cavity, a Model 810002 High Vacuum In-Line E-Vac Vacuum Generator, the smallest unit available, was more than sufficent for the job. However, the inlet pressure can be reduced to both minimize air consumption and dial the vacuum level down to a level that still works, but is not overkill for the application. Installation of the unit will lead to fewer rejected plastic parts.

Model 810008H 8.4 SCFM E-Vac High Vacuum Generator with Standard Muffler (Non-Porous)These single stage, cylindrical units are compact and easy to mount at the point of use. High vacuum units up to 27" Hg (91 kPa) with vacuum flows up to 15.8 SCFM (447 SLPM) are typically used for non-porous materials such as glass, steel sheet and plastic. Optional silencing mufflers are available. The Standard Muffler has a closed end and is suitable for applications that are free of dust and debris. The Straight Through Muffler is recommended where particulates are present since it will not accumulate debris that can erode performance. Straight Through Mufflers offer the best sound level reduction (up to 26 dBA).

Model 900768 1.5" X 1.12" - 1/4 NPT Female Bellows Vacuum CupsEXAIR vacuum cups are vinyl. They are ideal for general purpose applications and provide excellent resistance to wear. The Durometer rating (used to indicate the flexibility and stiffness of the cup) is A50. Temperature range is 32°F to 125°F (0°C to 52°C). Round Cups are best suited to smooth, flat surfaces. They will grip and release quickly. These cups hold their shape with extended use and grip well to vertical surfaces. Round cups with cleats are better at lifting heavy loads. Cups without cleats can be used for light lifting. Oval Cups provide the most vacuum due to the larger surface area. They provide more vacuum power than round cups and are suited to lifting heavy loads. They are designed to handle flat rigid sheet materials like wood, glass, cardboard boxes and composites. Bellows Cups are best suited to textured, uneven surfaces. The folds, called convolutions, provide a collapsible area that allows the cup to quickly compress when it touches the flat surface. The attach and release time is greater due to the significant volume of the cup. Learn More$31.00 -
