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

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.
