We are currently looking for qualified individuals to fill the following position:

Mold Design/CAE Engineer (NyproMold, Inc., Clinton, Massachusetts): Responsible for establishing criteria for moldability of plastic parts through detailed polymer flow simulations using MoldFlow Model. Analyze and optimize mold design cooling to simulate a broad range of fluid flow and heat transfer scenarios. Responsible for the coordination of detailed reports for supporting Early Supplier Involvment, Design and Mold Qualification teams. Specific duties include: Establish a proper part mesh with suitable density to ensure all necessary part details are captured. Select resin from the MoldFlow database, and research alternatives with polymer properties, as needed. Establish gate locations and enter preliminary process inputs based on the type of analyses required (i.e. Flow, Cool and Warp). Establish and analyze processes to optimize molding and melting temperatures, injection rates and fill times to determine fill pattern. Predict weld line locations, cooling time, cycle time, air traps and clamp force requirements. Develop analyses for gate location, core shift, runner balance utilizing advance simulations capabilities, and establish molding windows. Identify problem areas and suggest part design changes to optimize part design and ensure high quality part molding. This includes comparing and critiquing part design variations to eliminate ineffective design alternatives. Establish a proper cooling circuit model mesh for accurately predicting detailed flow and thermal simulations using Computational Fluid design. Identify cooling problems with existing cooling circuit designs, such as dead zones, hot spots, and channel sizing. Establish criteria to minimize parameters for pressure drop and recommend optimal coolant flow rates through the cooling circuits to meet cycle time requirements. Create detailed reports and Power Point presentations that include all analysis results and supporting process data. Review and present analysis results to supporting ESI, design and Mold Qualification teams. Participate in kick-off session on assigned projects to determine and understand all the customer requirements and design team deliverables which includes 3D data for moldability and critical design requirements, ejection, gating, cycle, cooling and molding machine specifications. Create concept core/cavity stackup layout which includes ejection, gating, cooling and mold sizing. Create preliminary mold design layout which needs to include the following for internal review: K.O. (knock-out) locations, runner feed system, molding machine data, side actions, cooling circuits and preliminary steel selections. Minimum requirements are: Bachelor’s degree in Plastics or Mechanical Engineering, plus 5 years of experience in the job offered or in a position related to mold design or computer aided engineering, involving: i.) plastic part design and the design principles for optimization filling of the part and understanding of the effect of part modification on polymer flow behavior; ii.) reading and interpreting process sheets to set-up simulations in CAE that duplicate the actual process conditions for part optimization; iii.) injection mold design and the understanding of mold cooling and ejection principles; iv.) mechanical and thermal properties (metal and plastic) to facilitate engineering calculations; and v.) mold design calculations and forces and stresses on components, deflection of components under operating conditions, ejection forces, clamp tonnage and proper runner and gate sizing for optimized mold processing. Individual must have: Bronze Certificate in Autodesk MoldFlow Insight – Mold Fill, Pack, Cool & Warp analysis along with Runner Balance and Molding Window analysis. Individual must have knowledge of: i.) Fundamentals of Polymer flow (including Viscosity, Shear rates, Shear stress, Melt Flow Rate, molecular and fiber orientation); ii.) Fluid flow principles and calculations; Turbulence, Reynolds’s number, Hydraulic (eq.) diameter, continuity equations, pressure drops, GPM estimations and channel sizing; iii.) Heat transfer principles and calculations for thermal conductivity, specific and latent heat, thermal expansion along with part and runner cooling times; and iv.) Pro-E Wildfire with the capabilities to create 3D models and model manipulation for accurate computer aided engineering representation.
