What are press knives?
Press knives function as specialized cutting tools for mechanical presses, shearing, punching, or forming materials under high pressure. Unlike general-purpose blades, these tools deliver uniform, repeatable cuts across diverse substrates – particularly cardboard, plastic films, rubber, leather, and thin-gauge metals.
Manufacturers typically construct press knives from hardened tool steels or carbide-tipped composites to withstand continuous high-cycle operation. Customize three core aspects to match your production needs:
Cutting profile: Flat, serrated, curved, or complex contours
Material specification: Tool steel or carbide composites
Operational alignment: Engineered for your press’s stroke pattern
This trifecta ensures extended service life while maintaining cut precision through demanding production runs.
Why Choose Sundi Press Knives
1. Precision Engineered Performance
Delivers cuts within exacting tolerances – ensuring dimensional accuracy and burr-free edges critical for precision-dependent applications like pharmaceutical packaging and electronics converting.
2. High-Speed Durability
Built for continuous high-cycle production, our blades maintain cutting integrity through extended runs. This directly increases throughput while reducing operational downtime.
3. Material Versatility
Handles diverse substrates – from paper and plastic films to rubber, textiles, and reinforced leather – without requiring recalibration between material shifts.
4. Long-Term Cost Efficiency
Premium tool steel or stainless steel construction provides 3-5× longer service life versus standard blades, reducing blade changeovers and cumulative production costs.
