Used MRT 3503 R Rotational Molding MachineTechnical Specifications &
Performance DataThe MRT 3503 R is a heavy-duty industrial forming
system engineered for high-temperature plastic processing and
container manufacturing. Its robust structure and precise motion
control make it suitable for demanding production environments in
industrial packaging and beverage production support, including
integration upstream of filling and labeling equipment within a used
bottling line or second hand production setup. The machine combines
large-format capacity with controlled rotation on multiple axes to
deliver consistent, repeatable forming quality.Model: MRT 3503

SystemsThe MRT 3503 R features precise rotational control with
independently adjustable primary and secondary axes from 0 to 8 rpm
for accurate thermal forming profiles. A digital WEISHAUPT burner
package enables stable process temperatures up to 300°C, with an
alarm setpoint at 340°C for enhanced protection. Electrical
integration is standardized at 400 V, 50 Hz with 42 kW installed power
for auxiliary systems. Operator safety is supported by guarded
enclosures and compliance certification, while color-coded protections
aid visual management. The controlled heating, rotation, and timing
provide consistent part quality and predictable cycle times in
industrial packaging applications.Production Line Integration
CapabilitiesThis machine can operate as a standalone forming cell or
be integrated into a broader production line with downstream trimming,
quality checks, and conveyance toward beverage production or
industrial packaging workflows. The generous envelope (3500 mm
spherical diameter) and multiple carriages support high throughput
configurations and flexible tooling strategies. Integration with
conveyors and handling equipment is straightforward thanks to clear
utility interfaces and stable thermal control.Machine Condition &
Maintenance HistoryThe unit is presented in working configuration with
compliance documentation and safety protections in place, suitable for
deployment in second hand or used bottling line environments where
upstream container forming is required. The combination of digital
burner control and defined alarm thresholds supports predictable
maintenance intervals and reliable operation.Operational Performance &
VersatilityWith adjustable multi-axis rotation, the MRT 3503 R
accommodates diverse mold designs and wall-thickness requirements for
plastic containers and industrial components. The high-capacity burner
ensures rapid and uniform heating, while controlled cooling aided by
defined water utilities supports dimensional stability and surface
finish. This versatility makes the system valuable for beverage
production support, industrial packaging, and general manufacturing
where robust forming capability is required.Installation Requirements
& Site PreparationPlan for a footprint accommodating 14960 mm length,
13026 mm width, and 5480 mm height with adequate access for
loading/unloading and maintenance. Utilities include 400 V / 50 Hz
electrical supply (42 kW installed), natural gas methane (approx. 46
m³/h continuous average), compressed air at up to 6 bar with 32000
Nl/h flow, and process/utility water at 2 bar with 4–6 l/min
consumption. Ventilation and exhaust management should be sized for
high-temperature operation and compliant with local regulations.Safety
Standards & Compliance CertificationThe machine is equipped with
protective guards and color-coded safety elements and is supplied with
a Declaration of Conformity. Over-temperature protection is integrated
through a 340°C alarm setting. The robust construction, controlled
utilities, and standardized electrical configuration support safe
operation in food and beverage packaging environments.
