The Haitian 3rd technology generation

Haitian International presents the third generation’s machines.
The new technology delivers even more efficiency, productivity, and new solutions

by Luisa Magni

Following the proven strategy “Technology to the Point”, the third technology generation from Haitian International (distributed in Italy by IMG, Capriano del Colle, Brescia) combines innovative new developments in hardware and software with beneficial optimization of machine models – both in the servo-hydraulic top sellers from Haitian and in the electric pioneer series from the Zhafir brand. The machines deliver even more efficiency, productivity and new “solutions to the point”. The versatility of the electric product range has been greatly expanded, and the performance of the servo-hydraulic two-platen machines has been significantly increased. Optimized drives and an open integration strategy for robotics and automation increase the scope for investment and flexibility in production. Ongoing improvements and the consistent improvement of standard components such as motors result in higher performance but also higher overall resource savings.

Facelift and technical optimizations: the third generation of the electric Zhafir family
The new patented concept for large electric injection units: 4 spindles + 4 motors

Worldwide, standard plastics with a theoretically high recycling rate are predominantly used in over 80% of standard applications. The Chinese company’s success strategy is to build injection moulding machines for precisely these standard applications and to continuously optimise them with regard to standard components. Technologies to the point support the resource and energy-saving use of raw materials to produce recyclable plastic parts. At the same time, the company has worked intensely to make electrical technologies affordable, because responsible mechanical engineering undoubtedly requires energy-efficient concepts.

New electric injection unit

Since introduction, the Zhafir Series have been continuously improved. The electric technology in generation 3 presents itself as even more customer-oriented thanks to an optimized toggle design and a new injection unit – especially in the upper clamping force segment. At the fair, the technological highlight is the new concept of electric injection units. Available in four design versions with 1, 2 and 4 spindles (patented and attractively priced), the injection pressure is significantly increased. At the fair Haitian presents the large 12,800 injection unit.

Compact and economical solutions

At K 2019, Haitian also shows its latest further development in Jupiter and Mars series.
Compact two-platen solution with even more free space and an open integration concept for intelligent control and digitization of process sequences. Design innovations lead to more stable platen movements and shorter dry cycle times. A Jupiter 5500III-2230 produces an LED light strip made of PC, integrated into a production cell with a 6-axis-robot from ABB.
The Mars Series remains the world’s best-selling injection moulding machine. The servo-hydraulic bestseller presents itself in the third generation with new motors, new machine design and many other improvements analogous to the Jupiter III Series. A Mars 1700III/plus produces bottle openers made of recycled PP with insert technology, integrated in a production cell including a Hilectro robot from Haitian Drive Systems.

Medical and packaging Applications

Another highlight at this year’s K is a fully electric dynamics with the highest precision and up to 70% energy savings. This topic is demonstrated on a Venus 1200III producing a medical part made of PP under a laminar flow box from cleanroom manufacturer Max Petek.

An application for the packaging industry is presented on an electric all-rounder with integrated hydraulic drive machine. A Zeres 2300F-830h – based on the latest third generation technology from Zhafir – produces a 4-cavity lid with IML, both made of PP, in a Sepro Robotique production cell.

The third generation Jupiter
Haitian has enhanced machine functionality with its new, third-generation Jupiter line of two-platen, servo-hydraulic presses. Jupiter III models (available in Europe since June 2019) offer a more-compact footprint while retaining the line’s energy-efficient operation. The new press series is available in 16 sizes with clamping forces ranging from 506 to 7,418 tons. The company designed it to produce large parts, such as trash bins, crates, automotive parts and appliance parts where surface quality is important.

More useful for many applications

The design innovations of Jupiter III Series lead to more stable platen movements and shorter
dry cycle times

Haitian says upgrades made to the Jupiter design make the two-platen machines more useful for many applications. he company upgraded the clamp’s design, injection unit and controller. The improvements result in faster cycles, more precision and easier maintenance. The clamp with has a simpler, more reliable and more precise design that results in 10 percent improvements in dry-cycle times and braking speeds, the company said. The redesign increased tie-bar spacing on various models, while the increased spacing allows for the use of larger moulds. The company also simplified the clamp design, eliminating the tie-bar adjustment oil cylinder. The high-pressure clamping cylinder now adjusts the tie bar and performs the mould-opening-breakaway function. The improved injection unit enhances processing flexibility and power. For improved pressure and speed, a larger, upgraded pump offers a 10 percent to 20 percent increase in power. A new high-drive servo system provides accelerated injection response within 100 milliseconds. To facilitate easier maintenance, the injection unit now swivels on all model sizes.

The new control system
Enhancements to the Keba controller make possible faster cycle times. These improvements result in an increase in signal accuracy from 0.1 mm to 0.01 mm. The controller is equipped with GoFactory, Haitian’s wireless communication interface network for software downloads. New equipment does not need to manually upgrade software and hardware, and users don’t need specialized expertise to install upgrades. Instead, they can simply download software from the cloud. Inside the Keba controller, Motion Plus software allows for improved communication, control and flexibility among the moulding machine’s various components, such as drives, pumps and sensors. It acts as a communication center to convert and filter moulding machine operating parameters for manufacturing-execution systems.
