China SK-2800U 2800 Ton Two-Platen Injection Molding Machine - Reliable Suppliers from Factory
Product Introduction
SK-2800U 2800Ton Two-Platen Injection Molding Machine: The Integrated Large-Scale Powerhouse for Heavy Industrial Manufacturing
Core Engineering Highlights
Shock-Free Synchronous Braking
A buffered mechanism ensures rapid, reliable clamping with zero impact.
Independent High-Pressure Cylinder
Facilitates controlled, slow high-pressure opening and enables easy tie-bar extraction for low-headroom facilities.
High-Rigidity Precision Guidance
An L-shaped rail on a robust frame guarantee ±0.05mm accuracy, ensuring rapid and stable platen movement.
Durable Guide Posts with Uniform Stress
Specially treated for rigidity and wear/corrosion resistance, these posts achieve over 99% force uniformity to prevent eccentric loading and maximize service life.

Exceptional Precision in Mold Opening Position
Achieves a repeatable mold opening accuracy of ±0.2mm—a fivefold improvement over standard three-plate machines. (Verified by internal 1200-ton testing).

Ultra-Sensitive Mold Protection
SK-U series machines' intelligent deceleration control provides unparalleled sensitivity, achieving the "A4 paper rebound" standard. It can stop on the slightest obstruction, ensuring your valuable molds are protected with maximum reliability.

High-Speed Performance, Lower Cycle Times
Experience significantly faster dry cycles. Our optimized system delivers rapid mold opening and clamping, translating directly into enhanced productivity and greater output. (Verified by 1200-ton internal testing).
