    Editor's Note: Each week, Rubber & Plastics News will take a look at some of the rubber industry's new products and innovations on www.rubbernews.com. Does your company have a new product or new innovation? To be considered for inclusion in this recurring feature, email [email protected].

    CoreTech System Co. Ltd. has released its Moldex3D's hot runner steady analysis that helps design the most optimal hot runner system.

    CoreTech said runner flow balance has been one of the most essential factors when it comes to a successful mold design, but achieving a balanced flow pattern is not always an easy task for many mold designers.

    When polymer melt flows through the runner, a frozen layer will be created along the flow path on the runner's wall, the company said, resulting in a smaller cross-sectional area for the flow to pass through. There are various factors that may influence the thickness of a frozen layer such as injected speed, mold temperature, or material characteristics, etc., according to the firm.

    CoreTech said the overall development time can be shortened when a CAE tool is applied to resolve the issue. However, CoreTech said in order to obtain the most optimal runner system design, a series of possible try-outs in a CAE simulation tool before one can find the most ideal molding scenario is still inevitable in this process.

    The goal of achieving a balanced flow in a hot runner system with trial-and-error method can be achieved through two ways, CoreTech said:

    • To enlarge the geometric size of the hot runner system in order to lower the pressure drop in the cavity; or

    • To ensure the symmetric geometry design of the hot runner system in order to adjust the gate and the runner's size

    The company said as the product design continues to advance in modern product development process, so does the design of a hot runner system. CoreTech said the more complex the hot runner design is, the more time it needs for attaining a detailed Advanced Hot Runner analysis. This is especially true for a multi-cavity mold design; however, CoreTech said the geometry and size of each cavity is the same, it is difficult to attain the most optimal filling result.

    In order to design an effective hot runner system that fulfills the lightweight design concept and achieves the desirable pressure drop range, CoreTech claimed it needs numerous attempts in CAE advanced hot runner simulation before the most optimal design can be attained. On an average, five or more design changes are required in this process before achieving a satisfactory analysis result. Thus, the time spent on simulation has taken too much time in the overall product development process, the company said.

    To address this issue, CoreTech said Moldex3D is rolling out a new feature—hot runner steady (HRS) analysis in the upcoming R14 version in aim of shortening CAE analysis and design optimization time. The company said Moldex3D's solver will conduct a HRS analysis based on the layout of the hot runners and the flow rate of each gate can be attained as a valuable reference for users to understand the flow behavior. Through HRS analysis, users are able to detect the potential flow balance issue at the early design stage in order to make appropriate design adjustments; and along with a detailed advanced hot runner analysis, users are equipped with powerful tools to examine and optimize all aspects of their hot runner design, which ultimately leads to a successful hot runner design, CoreTech claimed.

    Sick's Dx50-2 PRO distance sensor.

    Sick Inc. has launched the Dx50-2 PRO distance sensor featuring a proprietary high-definition distance measurement platform that the company said provides greater precision at longer sensing distances and an industry-leading operating temperature range and ambient light tolerance.

    Dx50-2 sensors provide precise and reliable measuring of ranges up to 10 m on black targets, Sick said, and up to 30 m on white targets. The sensors deliver up to 3,000 distance values per second for maximum throughput and process quality, and Sick said the Dx50-2 sensors have a rugged housing that meets both IP 65 and IP 67 enclosure ratings, wide operating temperature from –40 °C to +65 °C, and ambient light immunity that ensure reliable operation in harsh conditions. The sensors also feature an intuitive display and easy teach option, which Sick said saves time during installation and commissioning.

    The Dx50-2 sensors have settings for speed, sensing range and repeatability that Sick said can be adjusted to meet current requirements. The Dx50-2 sensors can be customized for a wide variety of applications, the company said, including detection and measurement of hot materials in the metal and steel industry, collision avoidance in container ports and positioning of robots in the automobile industry.

    Elasto Sweden's Mediprene TPE compound is for use in plunger seals in single-use syringes.

    Elasto Sweden A.B., part of the Hexpol TPE group, has expanded its range of Mediprene TPE compounds for plunger seals in single-use syringes. The new grades will be among the materials showcased at the Fakuma exhibition in Friedrichshafen, Germany, Oct. 13-17.

    Elasto Sweden said the Mediprene grades are sterilizable with gamma, EtO and steam, and representative grades have passed cytotoxicity tests according to ISO 10993-5 and biocompatibility tests according to USP Class VI. The Mediprene materials are latex free, the firm claimed, which reduces the risk of allergic reactions, and mediprene TPEs are resistant to many fluids used in the health care environment.

    The Mediprene grades are available in a range of hardnesses from 43 to 73 Shore A. The TPE seal, which is mounted on the end of the plunger, needs to provide a leakproof seal with the syringe barrel, according to the cmopany. Elasto Sweden said the Mediprene TPEs offer low compression set helping to maintain seal integrity.

    Elasto offer these grades as translucent or colored compounds, made from medical grade raw materials. Mediprene TPEs are being specified as an alternative to thermoset rubber, the company said. They require no vulcanization and are 100 percent recyclable, Elasto Sweden said. Consistent shrinkage also allows for tight dimensional tolerances with fewer process steps and without the need for additional operations such as trimming, the firm said.
