SPECIALTY PACKAGING SOLUTIONS ADD WEIGHT AND AESTHETICS TO YOUR LUXURY PACKAGING CLOSURE DESIGNS WITH DENSITY MODIFIED FORMULATIONS Consumers of luxury cosmetics and spirits tend to perceive added value from packaging that incorporates weight, aesthetics, and visual surface effects into the design. Injection-moldable Gravi-Tech™ density modified formulations can help you achieve the evenly distributed weight, complex designs, and visual surface effects of metal without the extra costs and steps associated with die cast mold tooling or secondary assembly operations. Achieve complex designs without expensive tooling – Gravi-Tech material can be injection molded into unique part shapes utilizing lower cost molds made of P20 or H13 steel.

Injection Molding of Plaques A Milacron injection molding machine was used to prepare plaques for the measurements of physical properties and adhesion. The barrel temperature of the injection molding machine was set from 180°C to 220°C (360°F to 430°F) and the injection velocity from 0.7 inch/sec to 2.0 inch/sec. They have good flow characteristics suitable for injection molding applications.

Injection molding of plaques A Milacron injection molding machine was used to prepare plaques for the measurements of physical properties and adhesion. Injection velocity at 51mm/sec. Injection velocity at 51mm/sec.

Long fiber reinforced thermoplastics provide structural performance that can go head-to- head with metals at a fraction of their weight while retaining the processing ease of injection molding. Pyrolysis removes the matrix polymer of injection-molded specimens to reveal the different internal fiber structure of long glass fiber and short glass fiber parts. DESIGN & DEPLOY WITH CONFIDENCE Transitioning from traditional materials to long fiber composites requires an integrated approach that includes material formulation, component design, and forming process.

These unique additives have been shown to have excellent results in a number of processes, including injection molding, extrusion, thermoforming, and vacuum forming.

However, metals also have known limitations that impact cost, processing, and design. As a result, designers are increasingly leveraging these benefits to advance innovation and product potential. WHY LFT FOR BRACKETS & LATCHES Reduced System Costs • High volume production efficiency due to injection molding (shorter cycle times) • Reduced secondary operations (no welding, surface treatments, etc.)

Design Considerations The material requirements of bondable TPE’s are different from conventional TPE’s and it is the same for designing parts. Unlike conventional part design, two component part design has to take into consideration shrinkage’s from two different thermoplastic materials. Shut-off’s should also be designed for the following reasons: 1.

ColorMatrix™ Fiber Colorant Solutions introduce late-stage color injection for the spin coloring process, and can help to transform the way safety straps, upholstery fabrics, footwear, apparel, industrial fabrics and more are manufactured. The new fiber colorant technology combines ColorMatrix liquid concentrates and proprietary high-pressure metering equipment to enable late-stage color injection during melt extrusion spin coloring. Further, several injection points can be added to run multiple colors or additives at the same time on a single extruder to enhance flexibility.

Injection molded TPEs are easily processed in complex molds, and it’s easy to add surface texture by bead blasting or chemically texturing the mold. Cycle times for injection molded TPEs are typically faster than alternative materials, resulting in reduced production costs.

Design Matters When designing TPE parts, strive to keep the part wall thicknesses as uniform as possible and radius all sharp corners. On the other hand, TPEs are most commonly processed using in-line, single-screw injection equipment that has been routinely used in the plastics industry for decades.
