High Rigidity & Precision, Suitable for High-pressure Molding of No-pre-drying Materials
5-point Double Toggle + Central Clamping Structure: Clamping force evenly distributed at mold center. Mold plates optimized by finite element analysis and thickened by 15%–20%, greatly enhanced rigidity. Deformation ≤0.05mm under high-speed & high-pressure, effectively preventing plate burst and tie-bar breakage. Adapted to high-pressure exhaust of no-pre-drying materials, ensuring uniform wall thickness, clean clamping lines and 30% longer mold life.
Extended Mold Stroke + Wide-plate Mold Capacity: Mold stroke increased by 15% vs standard machines, larger mold capacity for complex 2–8 cavity molds. Independent dual ejection cylinders with strong force and long stroke, ideal for complex product demolding and reducing mold sticking risk.
Dustproof & Wear-resistant + Safety Protection: Tie-bar ends equipped with standard bellows dust covers to block plastic dust and ensure smooth mold adjustment. Graphite copper sleeves used for tie-bar and ejection guides, low friction for fast & precise opening/closing, wearing parts life tripled. Fully enclosed sheet metal for high protection; low-pressure mold protection detects A4‑thin foreign objects, effectively protecting expensive molds.
High-efficiency Mold Adjustment + Balanced Stability: Motor-driven self-locking mold adjustment with gear transmission for stable high-speed operation. Inclined dual-injection hinge and integrated clamping arm keep frame balanced under heavy load, extending service life of tie-bars and mold plates.

Screw Dehumidification Core, Drool-proof & Wear-resistant, Suitable for Direct Molding of Wet Materials
Konger Patented Screw Dehumidification System: Core technology for no-pre-drying processing. Synchronous dehumidification during plasticization via special screw grooves and barrel vents. No drying equipment needed, saving 2–5 hours of drying time. Dust-free operation, stable product color. Production starts immediately after mold installation and material feeding, improving efficiency by 30%.
Bimetallic Special Screw & Barrel: Bimetallic screw (38CrMoAlA + tungsten carbide coating), heat-resistant (300℃), wear-resistant and corrosion-resistant. Suitable for direct molding of moisture-containing materials, service life tripled. Optimized screw flight increases plasticizing efficiency by 25%. Low AA value, small color difference, high product strength and toughness, solving bubbles, silver streaks and surface whitening.
Drool-proof Nozzle + Non-return Venting Device: Large-caliber nozzle (φ18–φ25mm) with leak-proof check valve to prevent melt drooling. Tight nozzle-mold fit plus screw venting minimizes cold slug and flow marks, meeting high-temperature, high-pressure, fast molding requirements for no-pre-drying materials.
Multi-zone Temperature Control + Independent Heating: Barrel independently heated by mold temperature controller, temperature accuracy ≤±1℃, suitable for 180–280℃ engineering plastics. High-temperature insulation layer reduces heat loss and energy consumption by 15%. Independent multi-zone control ensures uniform plasticization, product dimensional accuracy ±0.02mm.

Servo Energy Saving, Fast & Stable Response, Suitable for Short-cycle Molding of No-pre-drying Materials
Servo Pump Independent Drive + Closed-loop Control: Main and auxiliary movements are supplied with oil independently for synchronous, interference-free operation and 50% faster response. Pressure and flow closed-loop control reduces energy consumption by 30%–50% vs traditional fixed-displacement pumps. Oil temperature is stable with fluctuation ≤±2℃, meeting high stability requirements for frequent venting in no-pre-drying material molding.
High-speed Proportional Valve + Venting Synchronization: Standard mold opening/closing proportional valve provides millisecond-level response for smooth, precise movement. Optional mold opening synchronization and core-pulling linkage shorten single cycle by over 20%, with no-pre-drying molding cycle as low as 25–35 seconds.
High-quality Components + Optimized Oil Circuit: Adopts internationally renowned valves (Bosch, Yuken) and Taiwan-made valve blocks, with leakage rate ≤0.01L/min for long service life. Large-diameter unobstructed oil circuit reduces pressure loss by 15% and improves transmission efficiency, satisfying high-speed molding demands of no-pre-drying materials.
Low Noise & Constant Temperature + Easy Maintenance: Servo system reduces overflow heat; equipped with automatic oil temperature monitoring and cooling. Operating noise ≤72dB for better workshop environment. Centralized pipelines with maintenance space; universal wearing parts (seals) lower inventory cost, simplify maintenance and reduce total life-cycle cost.

Intelligent Venting Control, Multiple Formula Storage, Suitable for Batch Production of No-pre-drying Materials
Dual-core Specialized Controller + Large-size Touch Screen: Adopts high-end plastic machinery controllers from Siemens/Omron with dual-core processor for fast response. 10.4–15 inch color touch screen supports Chinese and English for intuitive operation.
No-pre-drying Material-specific Parameter Groups + Venting Control: Stores 120 sets of process parameters for no-pre-drying materials, supporting one-click switching for PA6/PA66/PC/ABS etc. Built-in venting pressure, speed and time control modules monitor venting status in real time, automatically adjust screw speed and backpressure to ensure full moisture and volatile removal, reducing defect rate from 8.5% to 1.2%.
Fault Self-diagnosis + Safety Interlock: Key electrical components (Schneider/Siemens) ensure high stability and anti-interference. Automatic fault code display for quick troubleshooting. Low-pressure mold protection detects A4-thin foreign objects to protect expensive molds. Clamping/injection interlock avoids damage from misoperation.
Data Traceability + MES Integration: Built-in Ethernet supports uploading production data to factory MES system. USB interface enables parameter backup for quality traceability and batch management. Programmable for automation integration (robots, stackers), realizing full-automatic production and cutting labor cost by over 30%.
