Used Molding Machine MRT 3503 R for big container in HDPETechnical
Specifications & Performance DataThe MRT 3503 R is a heavy-duty
industrial forming system engineered for high-temperature plastic
processing and container manufacturing (1.000/2.000/5.000L Tanks). The
machine combines large-format capacity with controlled rotation on
multiple axes to deliver consistent, repeatable forming quality.Model:

silverAdvanced Automation & Control 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 and quality checks. 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, 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 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.
