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
    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.
  • 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 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 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
    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 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
    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
    Our two-stage kneaders are specially designed for PVC kneading.
    GSmach has delivered more than 150 high-performance PVC kneaders.
  • 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
    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
    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
    - Degreasing of polymers
    - Compounding for the rotomoulding industry
    - Compounding of thermoset plastics
    - Wood and plastic compounds
    - EVA/TPU hotmelt compounds
    - Graft compounds

Filler Masterbatch Basic Formula

Base Resin Filler Type Additives
PE CaCO3 55-85% PE wax
PP Talc 25-60% White Oil
PS BaSO4 40~70% Anti oxidant

Color Masterbatch Basic Formula

Base Resin Pigments Additives
PE/PP/PS/PVC Organic pigments 15-40%  PE wax

Inorganic pigments incl.:TiO2 35-70%

Carbon black 35-55%

Effect Pigment 15-40%

White Oil
TPE/TPR/EVA Anti oxidant 

Feeding System

There’re two type feeding systems:


Volumetric feeding system

     1.Weigh the raw material separately according to the formula

     2.Place all the materials into the high-speed mixer for 5~10minutes

     3.Discharge the material into the spiral loader

     4.Load the material into the hopper of volumetric feeder


Loss-in-weight feeding system (automatically and higher accuracy)

     1.Put the raw material into each tank on the ground.

     2.Vacuum loader will convey each component into the storing silo.

     3.The raw material will fall into the loss-in-weight feeder automatically. The feeding system will feed the material separately into extruder according to your formula setting one the HMI.

Extruders for Filler Masterbatch Compounding

According to your application and output, there’re many different choices of extruders.

     •  Twin Screw Extruder

     •  Triple Screw Extruder

     •  Kneader + Single Screw Extruder

     •  Kneader + Twin Screw Extruder

Extruders for Color Masterbatch Compounding

Color Masterbatch can be used for any types of polymers and all kinds of products. GSmach have rich experiences in providing color masterbatch making machines.

According to your application & output, you can choose:

     •  Twin Screw Extruder

     •  Triple Screw Extruder

Extruders for Additive Masterbatch Compounding

One extruder can generate many types of additives. So, it requires a fast cleaning type strand die plat for any changes to the formula.

The bulk density of additive is relatively low, so the output mostly depends on the feeding capacity, not the torque of main motor; our twin screw extruder is more adapted for this process.

Single Screw Extruder
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 recipe3. 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.

Triple Screw Extruder
Triple Screw Extruder
The Triple screws of the GSmach series of co-rotating parallel three-screw extruders are arranged in a "one" shape and rotate at high speed in the same direction, subjecting the material to intense shearing, squeezing, kneading and grinding action for better homogenisation and dispersion. Compared to conventional twin-screw extruders, the triple-screw extruder has an additional high shear zone, which doubles the plasticising and mixing performance of the twin-screw extruder, resulting in high output and twice the capacity of the twin-screw extruder. The de-volatilisation efficiency is also significantly higher due to the increased specific surface area and increased surface renewal rate.

Two Stage Screw Extruder
Two Stage Screw Extruder
Certain polymers require pelletizing to be carried out under conditions without water and moisture, so that the extrusion system should have sufficient cooling capacity to cater for in this process; some materials are sorted into shear-sensitive or heat-sensitive categories. Two Stage Screw Extrusion System is deigned for such processes. Primary twin screw extruder provides mixing and dispersion without over-shear, lower speed single screw extruder provides enough cooling and pressure accumulation.
