Heavy-load Rigidity, Superior Dustproof & Durability, Suitable for Deep-cavity Large Molds of Fruit Crates
5-point Double Toggle + Central Clamping Structure: Clamping force is evenly distributed at the mold center. Mold plates are optimized via finite element analysis and thickened by 15%–20%, achieving a significant rigidity boost. Deformation is ≤0.05mm under high-speed and high-pressure conditions, effectively preventing mold plate bursting and tie-bar breakage. Tailored to the deep-cavity and large projected area characteristics of fruit crate molds, it ensures uniform product wall thickness and neat mold clamping lines.
Extra-long Mold Stroke + Enlarged Mold Capacity: The mold stroke is ≥800mm (compared with 600–700mm of standard machines in the same tonnage range), with greatly increased mold capacity, easily adapting to 2–8 cavity multi-cavity fruit crate molds. The dual ejection cylinders feature an independent design, delivering strong ejection force and sufficient stroke. Ideal for demolding complex fruit crates, it reduces the risk of mold sticking.
Enhanced Dustproof, Durability & Wear Resistance: The tie-bar ends come standard with bellows dust covers. The multi-layer corrugated elastic structure blocks plastic dust and debris, ensuring smooth mold adjustment and reducing the frequency of thread cleaning and lubrication by 50%. Graphite copper sleeves are adopted for tie-bar sleeves and ejection guide sleeves, while graphite copper blocks are used for the sliding feet of the moving platen and rear platen. With a low friction coefficient, they guarantee fast and precise mold opening/closing, extending the service life of wearing parts by 3 times.
High-efficiency Mold Adjustment + Safety Protection: Motor-driven self-locking mold adjustment, paired with gear meshing transmission, ensures stable high-speed operation. The fully enclosed sheet metal structure prevents foreign matter intrusion with a high protection level. The inclined dual-injection hinge movement and integrated clamping arm maintain rack balance and stability under heavy loads, extending the service life of tie-bars and mold plates.

High Flow Rate for Fast Plasticizing, Excellent Wear & Corrosion Resistance, Suitable for Special Materials of Fruit Crates
Large-diameter Bimetallic Screw + Dual-cylinder Injection: The screw diameter is increased by 20%–30% compared with standard machines, boosting injection volume by 40% and enabling one-step molding of large fruit crate products. Made of bimetallic material (38CrMoAlA + tungsten carbide coating), it boasts outstanding wear and corrosion resistance, suitable for hybrid production of recycled and virgin materials, with service life doubled. The dual-cylinder injection structure ensures stable injection pressure and a 30% faster response speed.
Special Screw for Fruit Crates + Multi-zone Temperature Control: The specially designed screw flight optimizes melting rate, improving plasticizing efficiency by 25% with low AA value and minimal color difference. Independent multi-zone temperature control (with a temperature error ≤±1℃) is tailored to the characteristics of HDPE/PP raw materials for fruit crates, ensuring uniform melt plasticization. This results in products with high strength, good toughness, and an improved pass rate in drop tests.
High-efficiency Nozzle + Leak-proof Design: The large-caliber nozzle (φ18–φ25mm) reduces flow resistance, fits tightly against the mold during injection, and minimizes cold slug and flow marks. Equipped with a leak-proof non-return device, the nozzle prevents raw material backflow and reduces reject rates.
Low-speed & High-torque Servo Plasticizing: Driven by a hydraulic motor, it offers wide raw material adaptability and is suitable for HDPE/PP materials of different viscosities (including mixtures with recycled material ratio ≤30%). It ensures uniform melt plasticization, and the impact strength of products meets national standard requirements.

Dual-servo Energy Saving, High-speed Rapid Response, Suitable for Short-cycle Fruit Crate Production
Dual-servo Pump Independent Drive + Closed-loop Control: The main and auxiliary movements are supplied with oil independently, enabling synchronous operation without interference and a 50% faster response speed. The pressure and flow closed-loop control cuts energy consumption by 30%–50% compared with traditional fixed-displacement pumps. The oil temperature remains stable (fluctuation ≤±2℃), eliminating the need for cooling in certain working conditions and delivering remarkable water-saving results.
High-speed Proportional Valve + Mold Opening Synchronization Function: The mold opening and closing proportional valve comes as standard, achieving millisecond-level response for smooth and precise mold opening movements. The optional mold opening synchronization and core-pulling linkage functions shorten a single production cycle by more than 20%, with the fruit crate molding cycle as low as 25–35 seconds.
High-quality Components + Optimized Oil Circuit: Internationally renowned valve groups such as Bosch and Yuken are adopted, along with Taiwan-manufactured valve blocks. The leakage rate is ≤0.01L/min for an extended service life. The large-diameter unobstructed oil circuit design reduces pressure loss by 15%, improves power transmission efficiency, and meets the high-speed molding requirements of fruit crates.
Low-noise & Constant Temperature + Maintenance-friendly Design: Servo drive reduces overflow-induced heat generation, with automatic oil temperature monitoring and heat dissipation functions. The operating noise is ≤72dB, improving the workshop environment. Pipelines are centrally arranged with reserved maintenance space. Wear parts (such as sealing rings) are universal, lowering inventory costs, simplifying maintenance, and reducing the total cost of equipment throughout its life cycle.

Intelligent Dual Control for High Precision, Multiple Formula Storage, Suitable for Batch Production of Fruit Crates
Dual-core Specialized Controller + Large-size Touch Screen: Adopting high-end specialized controllers for plastic machinery from Siemens/Omron, it is equipped with a dual-core processor for fast response speed. The 10.4–15 inch color touch screen supports Chinese and English languages, featuring intuitive operation that accommodates operators of different language backgrounds.
Fruit Crate-specific Parameter Groups + Formula Storage: It can store 120 sets of fruit crate processing parameters, enabling one-click switching for the production of fruit crates of different specifications (e.g., 400×300×200mm/600×400×300mm). The curve display of injection/holding pressure/cooling processes facilitates process optimization, shortens mold adjustment time, and improves production changeover efficiency by 40%.
Fault Self-diagnosis + Safety Interlock: Key electrical components (Schneider/Siemens) ensure excellent stability and anti-interference performance. Fault codes are displayed automatically for quick troubleshooting. The low-pressure mold protection function can detect foreign objects as thin as A4 paper, effectively protecting expensive fruit crate molds. The mold clamping/injection interlock prevents machine damage caused by misoperation.
Data Traceability + MES Integration: Built-in Ethernet supports uploading production data to the factory MES system. The USB interface enables parameter backup, facilitating quality traceability and batch production management. The program can be expanded to connect with automated equipment (e.g., automatic part pickers, stackers), realizing fully automated production and reducing labor costs by more than 30%.
