PlastiComp claims it has developed the next generation in long fibre reinforced nylon composite pellets (LFT-PA composites).
The main attributes of these materials are the high-flow characteristics and superior surface finish they exhibit even with high fibre loadings and without a reduction in thermal or mechanical properties.
PlastiComp’s proprietary high flow formulas enable moulders to achieve cycle time reductions up to 25% along with injection pressure reductions of up to 40% in thin wall parts (less than 0.100”). Flow lengths in thin wall parts can also be increased by as much as 30% (based on spiral flow data). Cosmetics are improved due to a resin rich surface that contributes to the elimination of glass fibre on part surfaces.
The reduced viscosity of these formulas gives improved design flexibility by allowing wall thickness reduction of up to 25% in some parts. It also gives moulders the ability to mould complex and large shapes with high filler contents. Reducing process temperature and pressure provides secondary benefits including longer mould life as well as reduced mould and moulding machine maintenance costs.
“Through the use of this material one of our customers was able to reduce melt temperatures by 30°F,” said Eric Wollan, Business Development Manager. “This allowed them to reduce cycle times and energy costs during the moulding process. The cycle times were reduced by 30% in this case and the moulder had the added bonus of great part appearance with lower mould temperatures.”

With environmental awareness stimulating interest in sustainable materials, issues such as recyclability and environmental responsibility are becoming ever more important.
A high-performance moulding compound from Hexcel has been used to produce a carbon fibre-reinforced plastic (CFRP) transmission crossmember using a zero- waste process ideal for high-volume manufacture.
