Report from Ruma, Serbia: How MAPRO opened the doors to Haitian’s European megafactory

Haitian Injection Moulding Machine Production Closer to European Customers

Haitian chose Ruma in Serbia for its location on major transport routes and proximity to European customers. The plant, which began production in September 2025, is intended to reduce dependence on shipping from China and enable a more flexible response to market needs.

During the tour, customers were accompanied by the MAPRO Slovakia sales team. They were therefore able to discuss technical details directly on the production floor with the people who provide them with support, service and project implementation in Slovakia.

The scale of the plant is underlined by the figures:

• 250 000 m² – site area,
• 60 000 m² – current production hall,
• more than 120 million euros – investment in the first phase,
• a further 60 000 m² – planned production expansion,
• 2 500 machines per year and 450 employees – the plant's long-term targets.

Haitian is gradually developing its own component production here, as well as cooperation with Serbian and other European suppliers.

CNC Machining and Precision Inspection Under One Roof

The tour took us to the CNC workshop with eight vertical and six horizontal machining centres from Haitian Precision. Platens, support blocks and guide and ejector components are manufactured here. 

Visitors' attention was drawn to the FMS flexible manufacturing system with two automated lines, which allow machining without an operator present. Operators prepare programs, supervise the process and inspect finished parts.

Component precision is also verified using a Hexagon CMM coordinate measuring machine. For large platens, the flatness deviation must be less than 0.08 mm. Mandatory inspection of the first part of each new batch is supplemented by in-process measurements.

From Warehouse to Assembly

Production is supplied by four storage areas with a total area of more than 15 000 m². Material movements are tracked using SAP and barcodes, while the FIFO principle ensures that stock received earlier is used first.

Before assembly, parts are degreased, rinsed, treated against corrosion and dried. Larger components pass through a spray cleaning line, while smaller ones are cleaned ultrasonically. The facilities also include a painting line with a designed daily capacity equivalent to eight machines.

Clamping and injection units, valve blocks and other modules are assembled at separate workstations according to standardised procedures. Overhead cranes help handle heavy assemblies – the largest of them immediately attracted attention. Its lifting capacity is 200 tonnes. Part of the hall is also ready for the future assembly of machines with clamping forces above 10 000 tonnes.

Final Assembly and Testing of Completed Machines

The prepared modules are combined into complete machines in an area of approximately 16 000 m². The production plan presented during the visit included:

• MARS and MARS SE: clamping force of 90 to 530 tonnes,
• Jupiter: clamping force of 450 to 1 080 tonnes.

After the electrical wiring, hydraulics and pipework have been connected, the mechanical components are adjusted, the control system is checked and protective guards are fitted.

Before dispatch, each machine must pass the specified tests:

• 3 000 consecutive moulding cycles without alarms,
• more than 10 000 machine cycles without faults,
• final inspection and verification that the delivery is complete.

Manufacturing Facilities in Europe, Support in Slovakia

The tour in Ruma provided an insight into injection moulding machine production and Haitian's plans for the European market. For MAPRO Slovakia customers, it was also an opportunity to discuss their operations' specific requirements with the sales team directly at the machines and to learn more about their manufacturer's facilities.
