Lightweight Design: Bigger Molds, Smaller Clamping Force
The automotive industry continues to pursue lightweight components to enhance fuel efficiency and handling. However, many of these parts remain physically large, requiring high-capacity injection molding machines. To reduce costs, OEMs often opt for machines with large mold accommodation but lower clamping force. CLF helps clients match mold dimensions with the optimal tonnage to ensure product integrity while saving energy and cost. For example, engine covers or bumpers benefit greatly from this tailored approach.
-
Lightweight Materials: Composite Material Compatibility
Composite materials (CM), such as PC and PMMA, are essential for producing lightweight, high-strength automotive parts. These materials are more viscous and require high injection pressure. CLF provides specially treated screws and barrels to prevent material sticking and to ensure a smooth surface finish. For optical-grade applications such as headlamps, we recommend a specialized barrel set designed for PMMA to prevent black specks and maintain consistent transparency.

High Productivity: Multi-Process Integration
Automotive interiors like dashboards and door panels often require complex, multi-step processing. CLF’s machines support integrated multi-functionality—combining processes such as overmolding and film insertion into a single cycle. This boosts productivity, reduces cycle times, and saves valuable floor space. Many of our customers have significantly improved throughput with these advanced, multi-functional setups.
