The 680‑ton servo injection molding machine is a benchmark‑level Injection Molding Machine in the medium‑large tonnage molding field. It is developed for standardized, large‑scale and high‑precision mass production of large‑size plastic products. Combining proven mechanical construction and intelligent servo control system, the equipment delivers high‑strength clamping capacity, stable injection accuracy and ultra‑low energy consumption. It is suitable for molding various products including large‑logistic components, home‑appliance housings, industrial plastic parts, large‑packaging articles and thick‑wall structural components. Widely adopted in daily‑goods, home‑appliance manufacturing, auto‑parts and general‑plastic industries, it serves as core Plastic Machinery for medium‑to‑large plastic manufacturers to expand production capacity and improve product quality control.
For clamping‑unit design, the machine adopts an enhanced toggle‑type clamping structure, equipped with thickened integrated cast‑steel platens and high‑strength alloy‑steel tie‑bars. The whole machine frame goes through stress‑relief treatment for outstanding rigidity, deformation‑resistance and heavy‑load durability. Its spacious mold‑mounting area accommodates various types of Plastic Mold, supporting long‑term high‑frequency operation of large‑size, deep‑cavity and thick‑wall complex molds. Multi‑stage speed‑pressure optimization is applied to mold opening‑and‑closing movements with soft start‑stop buffer and minimum operating vibration. It effectively avoids platen offset, product flash and mold collision‑wear under heavy‑load production, greatly extending mold service life and guaranteeing stability and consistency for mass production. The machine is fully qualified for 24‑hour non‑stop continuous factory‑production conditions.
As a high‑performance Servo Energy‑saving Injection Molding Machine, this unit is fitted with a new‑generation closed‑loop servo power system. Different from constant‑energy‑consumption conventional fixed‑pump injection machines, it dynamically and precisely adjusts pressure and flow output according to load requirements of each working phase: mold opening‑closing, injection, holding‑pressure, plasticizing and cooling standby. Unnecessary energy waste is largely eliminated during production, achieving comprehensive energy‑saving ratio of 25%‑70%. Meanwhile, hydraulic‑system temperature rise is significantly reduced, slowing aging consumption of hydraulic oil, sealing elements and hydraulic valves. The machine runs with lower noise and fewer failures, helping factories cut power expenses and maintenance costs in long‑run production with remarkable energy‑saving & efficiency‑improving benefits.
The injection molding system is fine‑tuned and upgraded. It adopts dual‑cylinder balanced injection structure paired with high‑rigid injection base to prevent shaking and offset even under high‑speed injection. Equipped with high‑precision sensor feedback devices, it enables accurate adjustment of multi‑stage injection speed, pressure, back‑pressure and position. Ultra‑high repeat positioning accuracy stabilizes wall‑thickness uniformity, surface flatness and dimensional tolerance for large‑size products, effectively solving common molding defects such as sink marks, short‑shot, flash and deformation. The machine comes with general‑purpose screw‑barrel assembly as standard configuration, compatible with multiple conventional thermoplastic materials like PP, ABS, PE and PC. It provides excellent molding adaptability to satisfy flexible‑production demands for diversified articles.
Featuring strong automation expandability with standardized and highly‑compatible interfaces, the machine can seamlessly connect complete sets of Plastic Auxiliary Equipment to build integrated automatic production lines. When working with an Autoloader Machine, raw materials can be conveyed in fully‑enclosed automatic mode to realize unattended feeding, preventing material contamination and spilling while greatly cutting manual feeding costs. Matched with a Drying Machine, it precisely dries moisture‑sensitive plastic raw materials, fundamentally eliminating molding defects such as air bubbles, silver streaks and cracks caused by damp raw‑material and comprehensively raising finished‑product qualification rate.
The electric‑control system adopts industrial‑grade dedicated intelligent controller with fast computing response and strong anti‑interference performance. Its intuitive operation panel simplifies parameter setting for quick operator adaptation. Built‑in multiple‑safety functions cover fault self‑diagnosis, overload protection, limit protection and emergency stop. Together with dual‑interlock protection of hydraulics and electrics, it ensures maximum safety for operators, molds and equipment. Reasonable layout facilitates heat dissipation, dust‑proofing and daily inspection & maintenance, shortening equipment downtime and improving overall production uptime.
To sum up, this 680‑ton servo injection molding machine features five core strengths: high rigidity, high precision, low energy consumption, wide compatibility and easy maintenance. It meets mass‑standardized‑production requirements as well as flexible‑production scenarios for multi‑variety & small‑batch orders. With comprehensive cost‑performance superior to ordinary same‑tonnage models, it stands as a reliable, cost‑effective preferred device for medium‑large‑tonnage plastic molding production.
