Control System
Drying Hopper
The drying hopper ensure that the material lines are completely cleared after each conveying cycle and that an equal amount of material is conveyed in each cycle.
51 Drying Hoppers are placed on a platform in 4 lines at SP Moulding
The capacity are from 40 to 380 litre Drying Hoppers
With a total capacity of 6530 litre
Drying Hopper
Desiccant Flex Dryer
The Desiccant Flex Dryer is designed for continuous drying of granular plastic materials
Hygroscopic, non-hygroscopic raw materials and regrinds in the temperature
The Desiccant Flex Dryer is able to supply dry air with a dew point down to ÷40ºC or lower
• 3 x Desiccant Flex Dryer 1500 are placed under the platform at SP Moulding
• With a total air volume at 4500 m³/hour
Desiccant Flex Dryer
Coupling stations links the processing machines to the drying system
4 Coupling stations, one to each hall at SP Moulding
With: 54 in, 208 out
Coupling station
Piping system
Piping system: Conveying the raw material to the processing machines
6.1 Kilometre of piping and 1.4 Kilometre hose system at SP Moulding
Stainless Vacuum Receiver
Stainless Vacuum Receiver forConveyance the Free-Flowing Granules
51 SVR are mounted on the Drying Hoppers at SP Moulding
The capacity are from 4 to 26 litre receivers
Integrated Dosing Valve
Stainless Vacuum Receiver with an Integrated Dosing Valve
85 SVR/IDV are mounted on the processing machinery at
SP Moulding
The capacity are from 4 to 50 litre receivers with IDV
Material Hopper
The capacity are from 5 to 50 litre Material Hopper.
85 Material Hopper are mounted under the IDV
The SVR/IDV with Hopper are mounted on the IMMs at SP Moulding
And connected via the piping system to the central drying system
SVR/IDV with Hopper
Scan Vacuum Station - I
Generates the vacuum necessary to convey the plastic materials.
Blower:LT6-I , 3,4kW
2 x LT6-I 3 x LT6-I
Scan Vacuum Station - I
3 x SVS-I are placed under the platform at SP Moulding
1 x 3xLT6-I Vacuum Station
2 x 2xLT6-I Vacuum Station
WAM filter
The self-purifying filter is located between the vacuum station and the vacuum receivers and is cleaned after each conveying cycle.
4 x WAM filters are placed under the platform at SP Moulding
Centralised system
By changing decentralised systems, to a centralised, have SP Moulding now 62 IMMs in the same area, where they had 46 IMMs in 2005.
The system is designed, dimensioned and customised in accordance with SP Moulding machine layout, requirements and requests.
