Introduction to the BU Series

• The BU6800, Asia's first ultra-large two-plate servo injection molding machine
• Clamping force reaches 6800 tons, with an extra-large template spacing and mold capacity
• Suitable for the production and processing of ultra-large products in industries such as aerospace, automotive, municipal transportation, and new rural construction
• The BU6800 injection molding machine has been inspected by the National Plastic Machinery Product Quality Supervision and Inspection Center and obtained a qualified inspection report
• Bochuang's two-plate development is based on European two-plate technology, innovatively developed by Chinese and European technical teams together
• Bochuang two-plate machines have applied for more than ten technical patents, and their technology is at an internationally leading level. They are suitable for forming large, deep-cavity complex products such as daily necessities, home appliances, automotive parts, logistics turnover boxes, and large pallets. Bochuang two-plate machines are especially used for low-pressure injection and vented injection molding, completing processes that are difficult to control with conventional machines.

The entire machine is designed to European standards;

Full hydraulic control of mold clamping, linearly controllable clamping speed;

Fine adjustment of clamping pressure, ensuring high repeatability and reproducibility.

A compact two-plate clamping unit minimizes floor space;

Two high-speed cylinders diagonally placed for rapid mold closing, shortening cycle time;

Short-stroke rapid pressure-increasing cylinders installed on the moving platen provide more uniform high clamping force;

Hydraulic and electrical dual safety interlock protection;

Low-pressure mold protection device.

Numerical control 10-stage injection, 5-stage holding pressure

Holding pressure start point control (time, position)

3 modes of automatic ejector selection function;

Automatic material clearing function.

Differential quick mold opening system;

Multi-pump energy-saving circuit;

High-performance imported hydraulic components optimized combination configuration;

High-reliability high-pressure clamping cylinder system.

Automatic installation and removal of tie rods, leading domestically

Effectively reduces mold lifting height, significantly reducing factory infrastructure investment

China's first to achieve automatic tie rod removal on two-plate machines

Clamping structure

Within the clamping unit, the moving platen has been optimized for flexible maximum template spacing to handle deep-cavity products.

Extra-long two-plate slide feet ensure precise movement of the moving platen under heavy mold installations, extending mold life.

Extra-long two-plate slide feet ensure precise movement of the moving platen under heavy mold installations, extending mold life.

Injection and screw guidance use linear guides for smoother and faster operation; the injection carriage is cast integrally, providing a rigid and compact injection platform.

Double injection carriage structure ensures better alignment and stability of the entire injection platform.

Control System

Entire series uses dedicated industrial automation control systems for injection molding machines

Hydraulic System

Bus-controlled servo power system, multiple servo pumps in parallel
