The 628-ton servo injection molding machine is a flagship model developed for mass production of large plastic parts, thick-wall components, large-area housings and deep-cavity molds. It is an upgraded Servo Energy-saving Injection Molding Machine. As a heavy-duty core Injection Molding Machine, it is manufactured in full compliance with rigorous industrial standards of Plastic Machinery, featuring enhanced rigidity, higher load capacity and superior molding stability. It serves as essential production equipment for medium and large injection molding plants to expand capacity and undertake sophisticated orders of large plastic products.
Equipped with a reinforced high-rigidity mold clamping structure, the machine optimizes toggle transmission and template stress distribution to withstand prolonged high-pressure working conditions. It effectively minimizes tiny template deformation under heavy loads and ensures smooth, low-vibration mold movement with outstanding repetitive positioning accuracy. The built-in intelligent low-pressure mold protection system can sensitively detect foreign objects and residual scraps inside the Plastic Mold, greatly lowering the risk of mold crushing for costly large molds, extending mold service life and stabilizing the yield during continuous mass production.
Powered by a new-generation servo closed-loop drive system designed following the configuration logic of an Oil-electric High-speed Injection Molding Machine, the equipment dynamically adjusts pressure, flow rate and speed to match load demands within milliseconds. Unlike conventional fixed-displacement pump machines, it eliminates unnecessary energy consumption during holding pressure, cooling and standby stages. It achieves remarkable energy-saving performance, with lower hydraulic oil temperature rise and quieter operation, supporting non-stop heavy-duty 24-hour production and cutting long-term operation and maintenance costs.
The injection unit is specially calibrated for heavy-duty large-tonnage applications, delivering even plasticization, sufficient injection pressure reserve and a wide adjustable injection speed range. It can stably process various industrial materials including PP, ABS, PS, PC and glass-filled modified plastics. Classified into the versatile Special Injection Molding Machine Series, it is suitable for manufacturing regular large daily goods, logistics crates and large housing products, as well as high-demand parts such as large automotive structural components, engineering plastic workpieces and thick-wall precision products, covering a wide range of industries.
To meet the demands of modern automated unmanned production lines, this machine can seamlessly link with complete sets of Plastic Auxiliary Equipment. For workshop mass production, an Autoloader Machine can be deployed for automatic sealed material conveying, a Drying Machine for precise raw material dehumidification, and a Mold Temperature Controller to maintain stable mold temperature. The coordinated operation of this complete set of Auxiliary machine reduces manual intervention, prevents defects caused by moist raw materials, and greatly improves molding consistency and overall production cycle efficiency.
Adopting an industrial intelligent control system, the machine supports fine independent setting of multi-stage injection, multi-stage holding pressure and multi-stage mold opening & closing. It offers stable parameter storage and strong anti-interference performance to maintain minimal dimensional deviation in mass production, achieving precision control comparable to High-precision Two-plate Injection Molding Machines and meeting mass production standards for high-end large precision plastic products.
Every finished machine undergoes comprehensive strict inspections, including heavy-load mold clamping durability testing, servo power stability testing, hydraulic tightness testing and safety interlock testing. Characterized by low failure rate, excellent durability and easy maintenance, this heavy-duty universal mainframe balances high cost performance and strong production capacity. It is an ideal molding equipment for medium and large plastic enterprises to expand scale, upgrade production lines and accept high-end large-component orders.
