BMB is a manufacturer of high-tech IMMs from 1000 to 45000 kN. Always focused on satisfying its clients through customised solutions and cutting-edge products. Main players in thin wall items production, but also active in the automotive, medical and houseware industry due to the design flexibility
BMB capitalized on all the experience gained in two specific areas, the one dedicated to fast cycling machines and the other dedicated to full electric technology, and created this innovative series that combines their advantages i.e. large capacity injection unit, precision, speed, robustness and low power consumption. Furthermore, the performance of the control unit, easily programmable and able to ensure extreme flexibility, makes the series user friendly. All the foregoing encapsulated within a range of models able to meet any requirement, with machines from 160 tonnes up to 2200 tonnes clamp force.
By using the special KW clamping system, platen deflection is eliminated, perfect parallelism is ensured and longer opening strokes are an additional bonus.
Platen movement is by special satellite roller recirculation screws, with direct in line drives that ensure high load capacity and better performance.
The machine reliability and rationality is enhanced by reduced footprint, brushless motors, liquid cooled and optimum cleanliness of the mould area.
The injection piston, perfectly balanced hydraulically, is connected directly to the plasticizing screw and rotates during the dosing phase.
This technical solution avoids the use of wear items such as thrust bearings, usually fitted inside the piston and further, the application of the Torque motor for the screw rotation on the same axis of the piston itself excludes any additional mechanical parts, such as gears and belts.
The injection phase is controlled via a Moog servo valve and a hydraulic accumulator system.
Numeric control system
All the BMB machines motors and hydraulic-mechanical functions are controlled by a special CNC machine tool numeric system perfected in the company to ensure the best performance in total safety. The drivers, which are interconnected and interact in real time and recover the braking energy, increase the energy efficiency of the system.
The system is completely integrated for the setting and control functions, making it easy to reach the parameters set for all the cycle values. The setting procedure is considerably simplified requiring only three values of position, speed and force to be set.
The IT intelligence manages perfectly all operational requirements, reaching quotas set accurately and automatically adjusts acceleration and deceleration.
