Kneader Compounding Machine

GSmach is one of the professional twin screw extruder suppliers for masterbatch compounding.

GSmach is a top plastic extruder manufacturer in China. We can provide complete masterbatch production lines.

We supply turn-key solutions to your masterbatch compounding projects. This includes material handling, dosing, extrusion, pelletizing and other aspects.

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.

What Masterbatch Machine 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.

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.

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

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

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.

GSmach masterbatch machine can be used for filler, color, additive masterbatch production.
