WEB EXCLUSIVE: An unfilled grade of Victrex 90 Series high-flow PEEK from Victrex USA was used to mold small medical pipette tips.

Tooling innovations at NPE focused primarily on multi-cavity closure and medical applications, though there was also a substantial emphasis on large automotive and appliance parts.

It's the first material characterization method developed specifically for evaluating the injection moldability of a plastic melt.

Experienced injection molders have long known that a resin’s melt flow index (MFI), measured under very low-shear conditions, provides very little information about how it will process under many orders of magnitude higher shear in an actual mold.

Balanced filling is critical for making identical parts, achieving high CPKs, holding tight tolerances, and getting “good” data from design of experiments.

Processors face a multitude of challenges whenever they approach an injection molding machine.

Incoe Corp., Troy, Mich., and Beaumont Technologies, Inc. (BTI), Erie, Pa., have agreed to allow each to sell the other’s products.

An economical approach to verifying that computer-aided flow simulation will give an accurate molding prediction with your particular resin is offered as a new service from Beaumont Technologies, Inc., Erie, Pa.

Beaumont Technologies, Inc., Erie, Pa., is now introducing its In-Mold Adjustable Rheological Control (iMARC) mold inserts for commercial sale.

The accepted ground rule for balancing melt flow in multi-cavity injection molds is to achieve equal flow distance from the injection point to each cavity.

A new line of presses for TPE or rubber is said to trim cure times by up to 50%. New TurboCure presses from Rep Corp., Bartlett, Ill., feature meltflow enhancements in the injection unit and the mold.

A novel technology allows injection molders to alter the flow pattern inside the cavity and balance the filling of multiple cavities by means of an external mold adjustment while the tool remains in the press. In this exclusive article, the system's inventor explains how it works.

Several new multi-cavity mold configurations and new graphics mark the latest version of the "5 Step Process" software for mold-balance analysis and filling diagnostics.

"In-Mold Adjustable Rheological Control," or iMARC, is a new tooling concept that provides an externally adjustable means of varying how melt flows in a cavity without in any way restricting the flow (unlike valve gates, for example). Now in beta testing, iMARC is a further development of the Melt Flipper technology from Beaumont Technologies, Inc., Erie, Pa.

New version 1.2 of "5 Step Process" mold-debugging software from Beaumont Technologies Inc., Erie, Pa., incorporates new graphics and adds 12 new multi-cavity mold configurations.

What should have been a routine injection molding job was plagued with problems right from the start.

From complete hot halves to individual nozzles, a host of new products promise smaller gate vestiges, less maintenance, better temperature control, and lower cost.
