Conveying the plastic granules automatically – and at the right time – means avoiding costly machine stops due to lack of materials, preventing material spillage, minimising the possibility of contamination and providing a clean, safe working environment.

MSM can offer its customers solutions to all problems of transporting materials, whether they are plastic granules, pellets or powders.

MSM feeding and conveying systems are divided into the following categories:

• Compressed air single-phase hopper loaders with the innovative Ejet-System° (HLV series);
• Compressed air single-phase hopper loaders (HLP series);
• Single-phase vacuum hopper loaders (HL and HLM series);
• Three-phase hopper loaders composed of receiver, blower and filtering unit;
• Central conveying systems.

In the plastics industry, in order to limit production waste, plastic materials must be dehumidified up to a well determined residual moisture content.

The proper dehumidification of plastics before their transformation in the plasticizing screw is therefore a key factor for attaining quality processing.

MSM products range for plastic materials dehumidification includes:

• Compressed air dehumidificators
• Single tower molecular sieve dehumidifiers
• Twin-tower molecular sieve dehumidifiers

Dehumidification systems can be used in different configurations, in order to implement single, centralized or multi-hopper solutions.

A wide range of process hoppers is available to satisfy any need.

In the field of plastics transforming, in order to obtain a high product quality, it is necessary, on some thermoplastic materials, to remove their surface moisture and to preheat them, before they reach the plasticizing screw of the transforming machine.

The right drying of non-hygroscopic plastic materials and their preheating is therefore is the first step in the direction of quality processing and energy saving.

MSM offer the following range of products for plastic materials drying:

• Single-phase hot air dryers
• Three-phase hot air dryers
• Ground hot air dryers
• WIND, PET treatment system

A wide range of process hoppers is available to meet every need.

MSM, at the forefront in the plastics dosing field, offers different systems suitable for application in the different fields of injection, extrusion, etc.

The systems for plastic materials dosing and blending presented by MSM are divided into the following categories:

• Volumetric dosing
• Gravimetric batch dosing
• Loss-in-weight gravimetric dosing
• Multibatch dosing
• Compound dosing
• Dosing for fluids

In addition to volumetric dosing systems, horizontal mixers are available to increase dosing performance.

Granulators produced by MSM has been manufactured both in design and in technical details to give a reliable, compact product for the recovery of sprues, trimmings etc. The low number of revolutions per minute and the multi-blade rotor make it possible to use low electrical power, obtaining, thanks also to a particular geometry of the granulation chamber, a low noise level and a low powder regrind.

Products from this category are:

• FW granulators
• Systems for trimmings in-line recovery

For plastics extrusion, MSM offers the customer different solutions for process automation, especially in the blown film and sheet extrusion of HDPE, LDPE, LLDPE and BIO plastic materials:

• Blown film extrusion management systems
• Gravimetric dosing systems for extrusion
• Cooling rings for blown film extrusion
• Automatic cooling rings with on-line film thickness control
• Film width measurement and control systems
• Systems for measuring film thickness profile through a fixed scanner (for rotating extrusion heads) or a rotating circular scanner (for fixed heads)
• Production web management system to improve product quality and increase productivity

MSM offers a wide range of storage and raw materials management systems, both single and centralized:

• Storage containers
• Modular storage containers
• Rapid siloing systems
• Traditional silos
• Thrust loading systems
• Big-bags loading / unloading systems
• Vertical mixers

In the field of PET treatment, MSM offers innovative solutions for:

• recycled PET treatment, WD system and CT crystallizers
• crystalline PET treatment, WIND system and DDT dehumidifiers
