These tools include mold-filling simulations to study fill patterns (including predicted pack and cooling) of the geometry and predict knit line locations at resin flow fronts to help ensure you are directing the best fiber alignment (strength) in the highest stress areas that your product endures when in use. Our onsite technical support team is here to help with process development, mold design suggestions, material training, troubleshooting, and continuous improvement. Let us walk you through: Optimizing the LFT Molding Processes • Ensuring proper drying and preparation of the material (review of drying equipment) • Processing guidance for the specific grade (temperature and pressure suggestions) • Primary process development (including runner & gate geometry) • Secondary operation process development • Tooling debugging/optimization, especially if the injection mold is new Troubleshooting • Failure analysis/issue resolution (including pyrolysis/burn-off reviews to study internal fiber structure and length) • Process/mold support to perfect finished goods • Equipment review Training • Polymers fundamentals training • Design guidance for LFT IN-HOUSE PROTOTYPING SUPPORT Our 55,000 square foot Application Development Center is most often leveraged for new program prototyping and R&D trials.

HVAC doors are typically produced by injection molding two parts that provide structural strength and air sealing performance. This global reach also allowed Avient to respond quickly to mold trials, and eliminate import and shipping challenges. Avient engineered a new customized formulation for the part, which provided both the processability required for extremely short cycle injection-compression molding, as well as including an additive to stabilize the material when in contact with copper.

Viscosity changes also influence other process parameters, such as hold time in the mold and temperature profiles, impacting the total cycle time of the process Ensure that cooling in the molds is operating efficiently and is balanced, and plan on revising the injection and temperature profiles Maintaining brand color equity, part dimensions, and mechanical properties are areas of concern when PCR is included at 30% or more in the molded part.

Most fluoropolymers, other than PTFE and polyvinyl fluoride (PVF), can be melt processed using conventional thermoplastic extrusion or molding techniques. PTFE can be applied as a coating, extruded as a paste, or molded using compression molding or metal powder-processing techniques.
