Longhua's 20 years of expertise in die-cutting technology

Over two decades, we’ve optimized machines for cigarette packs, wine boxes, pharmaceutical cartons, cosmetic packaging, and corrugated shipping containers—each with specific precision, speed, and material handling requirements.

We’ve advanced from ±0.15mm to ±0.075mm through continuous refinement in frame rigidity, gear precision, and servo control systems—ensuring consistent quality across millions of impressions.

Our pre-feeding alignment system and adaptive paper pressing mechanism were developed specifically to stabilize warped boards, ensuring smooth feeding and precise cutting without jams.

We use integrally cast ductile iron frames with stress-relief heat treatment, plus self-lubricating drive systems, to maintain mechanical integrity and ±0.075mm accuracy even after 10+ years of continuous use.

We pioneered pneumatic plate locking and centerline positioning, reducing die change time from 45 minutes to under 18 minutes—critical for short-run, high-mix production environments.

With 580-ton ultra-high pressure capability, our embossing achieves deep, sharp 3D textures on thick paperboard—combining embossing, foil stamping, and cutting in one pass without compromising registration.

Our dual-station parallel stripping and intelligent waste removal systems achieve >99.5% waste clearance, reducing manual intervention and scrap rates while maximizing material yield.

Every machine undergoes 72-hour continuous run testing at full speed with real materials, plus laser alignment verification—a protocol refined over 20 years to ensure zero-defect delivery.
