As the home appliance industry enters a new cycle of "large-size and thin-walled, spray free exterior parts, and black light production lines", driven by the "dual carbon" goal, leading enterprises no longer only consider the locking force and tonnage when choosing equipment, but also calculate two hard accounts:
✅ Yield account for large thin-walled components,
✅ Electricity bills and carbon emissions for long-term operation.
MideaHand over the order for the first thousand ton electric injection molding machine toBochuangBD1100——A locking force of 1100 tons, equipped with a 7200 large electric shooting platform ⚡ A domestically produced direct drive electric injection molding machine with a measured energy consumption of 0.215 kW · h/kg.
The difficulty of thousand ton level electrification,
Not about 'expanding', but about 'stabilizing'
The thousand ton electric injection molding machine has long been controlled by European, American, and Japanese brands, and the core difficulty has never been stacking the frame to 1100 tons, but ratherUnder large tonnage, it is necessary to maintain the repeatability and energy consumption curve similar to that of a small machine.
BD1100The solution is the amplification and implementation of Bochuang's more than 20 years of direct drive electric technology:
Embedded direct drive transmission
Inject the screw directly as
servo motorThe rotor spindle eliminates the intermediate connection between the belt/gear, achieving 100% consistency in action and 99.99% transmission efficiency;
Four in one intelligent electronic control
High response servo motor+driver+new generation intelligent computer+Bochuang's unique electronic control technology, multi axis synchronous drive for glue injection, mold opening and closing, ejection, and spin off;
AI process algorithm
Intelligent curve tracking of injection speed/pressure, combined with injection cloud MES self-learning, enables process parameters to change from "master adjustment" to "equipment self convergence".
✨ When it comes to high-end plastic parts for household appliances, the data is straightforward:
🔧 Position repeatability accuracy ± 0.05mm - large thin-walled panels and spray free appearance parts do not deform or run off edges;
⚖️ Weight repeatability accuracy<1 ‰ - batch consistency crosses the threshold of high-end home appliance supply chain;
🌡️ Temperature control accuracy ± 0.05 ℃ - color difference, shrinkage, and internal stress are all compressed together.
High end plastic parts for household appliances
0.215kW·h/kg ⚡：
Reduce the first level energy efficiency by nearly 40%
According to GB 30257 "Functional Efficiency Limits and Energy Efficiency Grades for Plastic Injection Molding",
electric motorThe first level energy efficiency threshold is ≤ 0.35kW · h/kg.
BD1100The unit product energy consumption measured on the Midea production line is 0.215kW · h/kg, which is nearly 40% lower than the national standard level one.
Converted to the factory ledger: A thousand ton machine runs continuously on the outer shell of household appliances, with each unit running for thousands of hours per year, and the saved electricity costs are direct profits; In carbon accounting, green factory certification, and export supply chain audit, this machine simultaneouslyElectricity costandcarbon emission intensityBoth indicators are lowered together. For home appliance manufacturers like Midea, which operate in large quantities and have long cycles, this is not an "environmental bonus", but a hard constraint on production line updates.
A machine,A comprehensive solution

moldPick up, visual inspection, and centralized feeding form a part of the household appliance black light production line. The customer is not only buying 1100 tons of locking force, but also the steady-state production capacity of each qualified product.
