Single Screw Extruder

1. Low price: single-screw extruders are compact and inexpensive. Twin-screw extruders are more than twice as expensive as single-screw extruders.
2. Simple recipe: single-screw extruders have a relatively simple process and recipe
3. wide range of applications: single screw is suitable for melt extrusion of polymers, for extrusion processing of pellet feed, such as forming, film blowing machines, injection processing, etc., and for a wide range of applications of raw materials.
4. Easy maintenance: In terms of maintenance, the single screw is simpler than the twin screw because the structure of the single screw is very simple and facilitates maintenance.
5. Basic principle of conveying: The conveying of single-screw extruders depends on the sliding friction formed between the raw material and the barrel.

 

Industry Application

Extensive Application Experience

Our twin screw kneaders are used for a wide range of applications:
filler masterbatches, colour masterbatches, additive masterbatches, biodegradable plastics, cable kneading, engineering plastics reinforcement (GF), 
PVC kneading, polyolefin kneading, reactive direct extrusion, thermoplastic elastomers,
PET pelletizing and other plastics such as PE, XLPE, WPC.
Filler Masterbatch

Filler Masterbatch

The filler MB is a concentrate of CaCO3 or Talc or BaSO4 in a polymer matrix. It can be used in applications such as injection moulding, blow moulding, films (single or multi-layer), sheets and tapes.

Compounding

Color Masterbatch

Single colour masterbatches or SPC (Single Pigment Concentrate), custom masterbatches, bespoke masterbatches. GSmach has the experience to help you produce high quality masterbatches.

Additive Masterbatch

Additive Masterbatch

Additive masterbatches have many applications. Any plastic product requires at least two types of additive. It can change the physical or chemical properties. For example, flame retardancy, thermal stability or weather resistance.

Engineering Plastic

Engineering Plastic

Engineering plastics compounding is a major application for twin-screw extruders. It is used extensively in the automotive, electrical, blow moulding, film and pipe extrusion, fibre and other industries.

Biodegradable Plastic

Biodegradable Plastic

Plastic waste is becoming a huge challenge for a greener and better world. We can provide solutions for the compounding of biodegradable additive masterbatches or biodegradable plastics such as PPC, PABT, PLA, PBS, PCL, TPS, PVA, PVOH.

Thermoplastic Elastomers

Thermoplastic Elastomers

Thermoplastic elastomers are used in automotive, wire and cable, construction and transport, plumbing, footwear. GSmach has extensive experience in the compounding of TPR/TPEs, TPO, TPV, TPU, TPC, TPA.

Cable Compounding

Cable Compounding

1) Polyethylene insulation and sheathing compounds 2) Cross-linkable polyethylene (XLPE) insulation compounds 3) PVC compounds for cables 4) Halogen-free flame retardants (HFFR)

PVC Compounding

PVC Compounding

Our two-stage kneaders are specially designed for PVC kneading. GSmach has delivered more than 150 high-performance PVC kneaders.

Direct Extrusion

Direct Extrusion

All raw materials, such as polymers, fillers and additives, are mixed or split fed, reacted and degreased in a high-speed twin-screw extruder and made directly into a final product such as sheet/film, bypassing pelletizing.

Polymer Compounding

Polymer Compounding

GSmach also offers large extruders for polyolefin compounding: polymer powders are pre-mixed with additives and then made into pellets with a capacity of up to 10 tonnes/hour. Our deliveries range from feeders to storage silos.

PET Recycling

PET Recycling

You can rely on GSmach's experience to develop and supply customised machines capable of handling tricky recycling tasks. No more struggling with the recycling of bottle-grade PET.

Other Compounding

Other Compounding

- Degreasing of polymers - Compounding for the rotomoulding industry - Compounding of thermoset plastics - Wood and plastic compounds - EVA/TPU hotmelt compounds - Graft compounds

What Lab Twin Screw Extruder Machine You Need ?

GS mach which is a manufacturing vendor, specializing in the twin screw extruder pelletizing line and spare parts, with high quality machine and competitive price.

Single Screw Extruder Machine

The single-screw extruder is equipped with a smooth or slotted feed barrel and has length-to-diameter ratios from 8 to 32.

It is mainly used to process melts with venting or vacuum for recycling or product extrusion, which typically includes polyolefin and engineering recycling, melt blow moulding of fabrics, direct extrusion of engineering plastics into films, sheets, plates, pipes and profiles such as PET, PA, PBT, ABS PC.

Our newly designed GS series high-efficiency single-screw extruders have innovative features focused on energy savings, more precise process control and higher output.
