Fewer part numbers, fewer purchase orders, less assembly labor, no plating or anodizing: savings that never show up in a per-piece material quote. https://www.shanghoplastics.com/en/insights/glass-fiber-orientation-strength/ https://www.shanghoplastics.com/en/insights/glass-fiber-orientation-strength/ Thu, 02 Apr 2026 00:00:00 GMT Glass fibers align with melt flow during injection. Strength along the fiber direction can be roughly double the cross-flow direction, and shrinkage differs between the two, which is the root cause of most warpage in GF parts. Gate position, planned at design stage, is the single most powerful control. https://www.shanghoplastics.com/en/insights/pps-vs-aluminum/ https://www.shanghoplastics.com/en/insights/pps-vs-aluminum/ Tue, 17 Feb 2026 00:00:00 GMT PPS+GF40% withstands 200–220°C continuous service, resists aggressive chemicals without any coating, is inherently flame retardant, and weighs 1.65 g/cm³ versus aluminum's 2.70. Aluminum keeps the advantage in absolute stiffness and thermal conductivity. For corrosion-exposed structural parts below its temperature ceiling, PPS+GF is usually the stronger total-cost answer. https://www.shanghoplastics.com/en/insights/metal-to-plastic-feasibility/ https://www.shanghoplastics.com/en/insights/metal-to-plastic-feasibility/ Thu, 22 Jan 2026 00:00:00 GMT Metal-to-plastic replacement makes sense when three conditions align: production volume high enough to amortize mold tooling, operating temperature within the resin's limit (PPS+GF is rated 200–220°C continuous), and stiffness that can be recovered through ribs and wall design. Under those conditions, typical weight savings land in the 20–50% range.
