PVC Granules Manufacturing Process Step-by-Step (2026)

What Are PVC Granules?

PVC granules are small pellet-shaped plastic raw material made from PVC resin, additives, fillers, and stabilizers. These granules are processed further in injection molding, extrusion, and other plastic production methods.

PVC granules are mainly of two types:

Rigid PVC Granules (Used in pipes, profiles, doors, windows)
Flexible PVC Granules (Used in cables, footwear, hoses, insulation)

Why PVC Granules Are in High Demand?

PVC granules are highly popular because they offer:

Strong durability
Chemical and water resistance
High flexibility (in flexible PVC)
Easy molding and extrusion
Cost-effective production
Suitable for industrial and domestic applications

Because of these advantages, PVC granules manufacturing is a fast-growing business in India.

PVC Granules Manufacturing Process – Step-by-Step Guide

The PVC granules manufacturing process involves compounding and extrusion. Below is the complete step-by-step method used in industrial PVC granule plants.

Step 1: Raw Material Selection & Preparation

The first step is selecting the right raw materials based on the required PVC granule type.

Common raw materials include:

PVC Resin (Main raw material)
Plasticizers (For flexible granules)
Calcium Carbonate (Filler)
Stabilizers
Lubricants
Pigments / Color Masterbatch
Processing aids

The quality of raw material directly affects the strength, flexibility, and durability of the final granules.

Step 2: Accurate Weighing & Batch Mixing

After raw material selection, all ingredients are weighed as per the formula. Accurate formulation is very important in PVC granule production.

Machines used:

✅ High-Speed Mixer Machine

This machine mixes PVC resin, additives, stabilizers, fillers, and color evenly.

Mixing ensures:

Uniform color
Proper chemical blending
Consistent granule output

Step 3: Heating & Hot Mixing Process

In the hot mixing process, the mixture is heated at a controlled temperature to blend additives properly into the PVC resin.

Why hot mixing is important?

Ensures smooth melting in extrusion
Improves granule quality
Enhances final product strength

Machine used:

✅ Hot Mixer (PVC Compounding Mixer)

Step 4: Cooling Mixing Process

After hot mixing, the material must be cooled down immediately to avoid overheating and to stabilize the compound.

Machine used:

✅ Cooling Mixer

Cooling helps in:

Maintaining compound stability
Preventing premature melting
Preparing material for extrusion

Step 5: Feeding the Material into Extruder

Once the compound is ready, it is fed into the extruder machine for melting and processing.

Machine used:

✅ PVC Granules Extruder Machine

The extruder melts the compound using:

Heating zones
Screw rotation
Pressure control system

This is one of the most critical steps in PVC granules manufacturing.

Step 6: Melting, Mixing & Compounding in Extruder

Inside the extruder barrel, the compound melts uniformly. The screw rotates continuously and mixes the material to form a homogeneous molten mixture.

Extruder types used:

Single Screw Extruder
Twin Screw Extruder

Twin screw extruders are widely preferred for high-quality PVC granule production because they provide better mixing.

Step 7: Die Head Formation

After proper melting, the molten PVC comes out through a die head.

Die head function:

Shapes the molten PVC into strands
Controls thickness and flow

Machine part:

✅ Extruder Die Head

Step 8: Cooling Process (Water Tank Cooling)

The hot PVC strands coming out from the die are immediately passed through a water tank for cooling.

Machine used:

✅ Cooling Water Tank

Cooling is important to:

Maintain shape
Prevent sticking
Improve hardness and finishing

Step 9: Air Drying / Water Removal

After cooling, the strands may contain moisture. Therefore, drying is necessary.

Machines used:

✅ Air Knife System / Dryer Unit

This removes excess water and prepares strands for cutting.

Step 10: Granule Cutting / Pelletizing Process

Now the cooled strands are cut into small pellets (granules).

Machine used:

✅ PVC Granules Cutter Machine / Pelletizer

The cutter cuts the strands into uniform size granules depending on requirement.

Step 11: Vibrating & Screening Process

After cutting, granules are screened to separate dust and uneven size pellets.

Machine used:

✅ Vibro Screen / Vibrating Separator

This ensures:

Clean output
Uniform granule size
Better quality control

Step 12: Final Collection & Packing

The final PVC granules are collected and packed into bags for storage and transportation.

Packing options:

25 kg bag packing
50 kg industrial bag packing
Jumbo bag packing

Granules are now ready for sale or further production use.
