The sCOMPACT dryers are designed with flexibility in mind. The compact dryers offer an integrated solution, combining the drying and conveying of the raw material in one unit. The dryers are available in three versions, each with a drying bin of the size 80, 150 or 250 litres and up to three hopper loaders for conveying to the drying bin and two processing machines. As standard, this compact dryer is equipped with dew point control, overdry protection and dry air conveying function with line purging. Thanks to a modern 7" touch screen colour display, all conveying and drying functions can be shown and monitored in a user-friendly way. 16 user languages can easily be selected.

Screw-in heating elements are electrical heating elements that are used to heat liquid and gaseous media. The element consists of three parts: The bent tubular heating element, the screw-in thread and the connection housing.

The screw-tip-set is the heart of the plasticising unit. Screw-tip-sets must close safely and should allow a constant mass cushion in order to guarantee high repeatability to ensure even dosing. There are no good or bad screw-tip-sets, only suitable and unsuitable ones. Screw-tip-sets by Groche aim to achieve minimal wear and a long service life. + High wear resistant + Corrosion resistant + Special geometries + Extensive stock + Optimised coating

The servo-electric linear unscrewing unit (SLU) combines the unscrewing motion with a synchronized, linear slide movement. It demolds spiral internal and external contours with micrometer precision and repeatability. The standardized core holder accommodates individual mold contour attachments, enabling quick changes between different contours and pitches.

We manufacture screws as individual as your plastics. They are performance optimised, highly resistant to wear and corrosion-proof. Our screw production can meet your requirements from Ø 12 – 200 mm, up to a length of 5000 mm. In order to minimise friction, the manufacture of screws for plastic processing machines sets a high standard on the production process as far as finishing precision and surface consistency is concerned. The screw has the task of drawing in the granular plastic, to continously convey, to compress and to perfectly homogenise it in the output area. Groche screws have an exact geometry, which is suited to the relevant demands and areas of the application. + Ø 12 – 200 mm + Length up to 5000 mm + High wear resistant + Corrosion resistant + Individual geometries + Optimised coating

Flexible and compact energy-efficient small dryer The sDRY 40/80 dry air generators provide an exceptionally energy-efficient solution for material drying when paired with the sDRYBIN S drying bins. The small dryer series includes several models with drying capacities of 40 and 80 m³/h and drying bins ranging from 15 to 250 litres. All models can be configured or extended to meet growing and changing requirements. They help plastic processors cost-effectively equip individual processing machines or production cells in stages, based on demand. The series comes as standard with dew point control and an intelligent regeneration function. Additionally, optional features such as a return air water cooler and a conveying unit are available. The conveying module allows the sDRY 40/80 to be easily integrated into existing conveying systems or equipped with a single hopper loader. A modern control with a 7-inch touchscreen colour display allows for easy viewing and monitoring of all operating data, including historical curves. Additionally, 16 different user languages are available as standard.

Modular drying system for flexible drying solutions The sDRY MM / MD dryer series offers a fully modular drying management system. The system consists of one sDRY MM main module and can be flexibly combined with up to twelve sDRY MD drying modules. Each drying module can be operated independently and can be expanded or reduced at any time by adding further sDRY MD modules. The system can therefore be adapted to current production requirements by freely combining and arranging the drying modules. It offers maximum flexibility without interrupting the production process. The series consists of one sDRY MM main module. This can be supplemented with up to twelve sDRY MD drying modules. Drying capacities from 900 to 5400 m³/h can be achieved. This drying can be combined with a wide range of sDRYBIN A drying bins from 15 to 2400 litres. Dry air volume: 900 - 5400 m³/h Dew point: < -60 °C

AZO feeding hopper type ET...VS GA with integrated vibrating perforated sheet and evacuation of coarse materials The hopper serves to feed bulk solids in powdered and granular form into closed materials handling systems, such as pneumatic conveying systems. Products can be fed from sacks, boxes, barrels or similar receptacles. As different branches will have very diverse requirements regarding quality and hygiene, the feeding hoppers are available in a variety of materials and surface finishes.

Akolyt™ copolyesters have been specifically developed for the extrusion of technical films for a variety of applications, including but not limited to, credit cards, loyalty cards, chip cards, business cards, 2D and 3D furniture lamination films and graphic arts. Akolyt™ KB 311 Elongation of films produced with Akolyt™ KB 311 permit thermoformed deep drawing, at the same time as its relatively low Tg grants energy cost savings while guaranteeing perfect adhesion to itself. Akolyt™ KM 900 Elongation of films produced with Akolyt™ KM 900 permit thermoformed deep drawing, at the same time as its relatively low Tg grants energy cost savings while guaranteeing perfect adhesion to substrates.

Selbstverlöschende Compounds tragen dazu bei, die Brandgefahr bei Elektro-, elektronischen und Haushaltsgeräten sowie in E-Mobility-Anwendungen zu verringern. LATI liefert Produkte, die für die Entflammbarkeitstest nach UL 94, Glühdrahtprüfung nach IEC 60335 (GWIT, GWFI, GWEIPT) sowie Temperaturalterungstests nach UL 746b optimiert sind. Zudem bieten wir ein breites Portfolio an Compounds für Bahnanwendungen, die die Anforderungen der EN 45545 und NFPA 130 erfüllen. Unsere selbstverlöschenden Produkte sind erhältlich mit herkömmlichen Flammschutzmitteln wie Halogen, rotem Phosphor oder Intumeszenz-Systemen. Zudem bieten wir Compounds mit geringem Umwelteinfluss, die ohne Halogene oder roten Phoshpor flammgeschützt sind.

LATILUB self-lubricating materials limit friction and wear between elements in relative motion like gears, bushings and bearings, cams, pins, sliding surfaces, and so on. Unlike metal or ceramic solutions, the LATILUB compounds do not require external lubricants or maintenance, ensuring cleanliness and reliability over time. The base polymers are modified with graphite and molybdenum disulphide, with silicon, PTFE and UHMWPE to drastically reduce the static and dynamic friction coefficient, or with aramid fibres to limit wear and abrasion. A solution for every pressure, speed, load and temperature requirement.

Semi-finished products made of ZEDEX® enigineering & high-performance materials are available in the form of sheets, rods and hollow rods. The ZEDEX® dimensions’ availability depends on different factors such extrusion feasibility, known market needs, internal strategic decisions etc.
