Gammadot Rheology gains Moldex3D Approval

Following discussions with leading Taiwanese 3D CAE software providers, CoreTech System Co., Ltd, Independent testing specialist Gammadot Rheology has been awarded ‘approved laboratory’ status for the provision of materials characterisation data for Moldex3D – CoreTech’s flagship true 3D flow simulation software package.

Mark Edwards, Gammadot’s principal said, “Gammadot is delighted to become the preferred supplier of materials testing services to Moldex3D’s European software users, and look forward to providing fast, accurate solutions to their data requirements in a timely & confidential manner”.

Gammadot is uniquely suited to supporting Moldex3D as prior to setting the company up in 2006, Edwards was solely responsible for the provision of data for packages such as Moldflow, Fillcalc, & Sigmasoft3D, during 18 years service with Rapra Technology Ltd. In addition to materials characterisation services, Gammadot also offers support in the form of failure analysis and quality control programmes utilising a range of rheological & thermal test methods.

Moldex3D is a leading CAE product for the plastics injection moulding industry. With the best-in-class analysis technology, Moldex3D can help you to in-depth simulate the widest application range of injection molding processes to optimize product design and manufacturability, shorten time-to-market, and maximize product ROI, (return of investment).

PvT LVDT Calibration Improved

The next 12 months will see a phased package of refurbishment & improvements to the Rapra Technology-developed PvT apparatus. Phase one has involved the manufacture of a new system for the insitu calibration of the LVDT transducer which is seated below the pressure vessel.

The LVDT measures the expansion / contraction of the sample cell bellows assembly via the displacement of a rod attached to the base of the cell, (for further information on the measurement principles see HERE).

Because of the location of the LVDT & the sensitivity of the zero point adjustment system it is attached to, calibration of the transducer had traditionally been difficult. The new system involves screwing the existing displacement rod onto a calibrated vernier micrometer head via a stainless steel extension bar. The rig is lowered down into the barrel and the head secured to the top of the barrel. The LVDT is then zeroed and positive / negative values of displacement read from the digital display against actual readings of displacement generated by the incremental movement of the micrometer head.

The design of a bespoke fast cooling system is completed and as part of phase two of the development, this is hoped to be produced & commissioned before the end of 2009.
