China Professional Single Screw Extruder Manufacturer — Granuwel

Single screw extruders are simple in structure, low in price and easy to operate. Also, it is ideal for the plasticization and extrusion of polymers as well as the processing of pellets.

Granuwel has significantly refined the design and technology of single-screw extruders over conventional single-screw extruders, nearly doubling their capacity while halving their energy costs. Not only does this improve the extruder’s own efficiency, but it also saves production costs for the users.

GDE Series Single Screw Extruder

GDE Series Single Screw

Technical characteristics:

(1) The motor and the transmission box are connected by a coupling, and the direct-connected.
Transmission has high transmission efficiency; the equipment has lower energy consumption and more compactness.

(2) The barrel is equipped with a vacuum exhaust port, and the screw exhaust structure design.
Increases the functions of exhaust and devolatilization compared with the conventional single-screw extruder, and expands the function and application field of the single screw extruder.

(3) The barrel can be cooled by a fan or by circulating soft water, and equipped with an imported.
Temperature control system and PID parameter self-tuning function, the temperature control is more accurate; a high-speed, building block-type single-screw extruder has been successfully developed, giving the single-screw extruder more large value space.

Application areas:

It is mainly used in the molding extrusion or granulation process of products that need to exhaust or vacuum the melt, including the recycling and granulation of polyolefins and engineering plastics, and the direct extrusion of engineering plastic products such as pipes, sheets, films and Extrusion molding of profile products, setting materials include: PET, PA, PBT, ABS, PC, etc.

Wide application experience

Biodegradable plastic is a plastic that is degradable by natural microorganisms like bacteria, fungi and algae. An ideal biodegradable plastic is a polymeric material that performs well, can be fully decomposed by microorganisms after disposal, and ultimately becomes a component of the carbon cycle in nature through inorganization.

Color masterbatch is an integral part of the plastics industry. Not only can it give color to plastic products, increase the value of goods, enhance certain performance of plastics, but also can give particular optical properties to materials.

Started in the 1940s, the new functional polymers, which primarily include all kinds of engineering plastics (such as PA, PC, ABS, PET, PPS, etc.), are already used in electronics, electrical appliances, automotive, transportation, aviation, defense and military industries, etc.

Filler masterbatch is available for processing plastic films, garbage bags, shopping bags, undershirt bags, packaging bags, etc. It has excellent dispersion, blown film without white and black spots, and high fineness to ensure the luster and toughness of the product.

Non-crystallization dry PET sheet extrusion offers several advantages. It is used to produce PET/PLA sheet without the energy consumption of pre-drying crystallization and adapting to the production of materials with high output, low energy consumption and high plastic quality.

The PET waste plastic bottle cleaning line means that the waste plastic bottles are de-labeled by the de-labeling machine, pulverized by the crusher, and then processed by cleaning and drying equipment, so that the recycling and integration of waste plastic bottles becomes a new type.

Thermoplastic Elastomer has extensive adjustable hardness and physical properties. Also, it doesn’t need to be vulcanized, is recyclable, and can reduce costs, so the application areas are relatively wide including seals, automobile interiors, adhesive coated materials, various pipe fittings, etc.
