What if your bicycle chain is loose or rusty? It does not move smoothly, does it not? You have to pedal harder; it whines, and sometimes the cycle stops in the middle.

Now imagine a large plastic plant. The screws and barrels in the plastic processing machinery are similar to the chain on the bicycle. If they are not maintained, the entire machine becomes slow, frequently breaks down and squanders both time and money.

That is why screw and barrel care is extremely important. And today, being a reliable screw barrel manufacturer in India, we at Shreeji Corporation are going to give you some simple but strong tips on how to make your screws and barrels live longer and perform better.

Shall we start?

1. Why Do Screws and Barrels Wear Out?

Screws and barrels are the equivalent of the heartbeat of plastic processing equipment. They continue to move, melt, and mould the plastic. But over time, they are subjected to:

• Adhesive wear – metal rubbing against metal.

• Abrasive wear – tough plastics (such as fibreglass or fillers) wear away the surface.

• Corrosion – chemicals or acids corroding the metal.

• Thermal damage – excessive heat alters the metal's strength.

When this happens, what do you see?

Products won't always turn out right. Machines get slower. Electricity bills increase. And the worst part: the machine could just stop working suddenly.

That is why all the screw barrel makers in Ahmedabad will inform you of the same thing: catch it early. Quick checks can prevent major losses.

2. Choosing the Right Material

Here's a simple fact: when you're baking bread, you require proper flour. When you're producing plastic, you require proper alloys for your barrels and screws.

Different plastics need different materials. For example:

• PVC is chemical-rich but soft, so you require corrosion resistance.

• Fibreglass plastics are rough and hard, so you require wear resistance.

• Engineering plastics require strength as well as heat resistance.

That is where bimetallic barrels and surface treatments such as nitriding or hard chrome plating enter.

At Shreeji Corporation, a prominent screw barrel producer in India, we tailor these materials for you. It is like getting your suit tailored—just for your machine, not one size that fits all.

3. Cleaning and Checking Regularly

Here's a great example. Don't brush your teeth for a week. Terrifying, isn't it? Buildup accumulates, teeth get weak, and you get cavities.

The same thing occurs with screws and barrels when you don't clean them. Plastic buildup accumulates, burns, and wears out the surface.

So what should you do?

• Clean screws and barrels with the right tools after every large production run.

• Employ purging compounds to safely remove residual plastic.

• Schedule checking—check for scratches, grooves, or abnormal wear.

Many leading screw barrel producers even supply specific cleaning equipment. Their use keeps your equipment secure.n offer special cleaning tools. Using them keeps your machinery safe.

4. Keep an Eye on the Process

Machinery is similar to children—they must receive the proper care. You exhaust them if you work them too hard.

Key things to check:

• Temperature – too hot weakens the metal, too cold causes plastics to stick.

• Screw speed – too fast and it gets worn out faster.

• Pressure – too high pressure and it cracks or gets scored.

• Feed rates – either too little or too much raw material keeps the process unstable.

Train your operators to pay attention and listen. A slight noise, a peculiar smell, or a slight product quality change—these are warning signs. Act early!e. A small noise, a different smell, or a slight change in product quality—these are warning signs. Act early!

5. Smart Care Tips

Want your barrels and screws to last a long time? Just follow these simple steps:

• Don't let rocks, metal fragments, or foreign objects fall into the hopper. They work like sandpaper and grind everything within.

• Don't heat or cool it suddenly. It gets a shock out of the metal and cracks it.

• Don't dry run the machine. It overheats the screw and ruins it.

• Lubricate and switch off the machine at the end of each shift.

Think of it as maintaining your car. Oil it regularly, no hard riding, and gentle parking, keep the car in good condition. Same principle here.

6. Repair or Replace: When to Decide

Nothing lasts forever. Even the best screw barrels require repair or replacement after years of use.

• If product quality declines repeatedly.

• If you see significant scratches, cracks, or barrel size changes.

• If usage of energy increases but production decreases.

• In such instances, repair with alloy surfacing or re-machining can be done. However, if wear is excessive, replacing would be a better option.

In such cases, repairing with alloy surfacing or re-machining is possible. But if wear is too much, replacing is better.

An expert screw barrel manufacturer in India, such as ourselves, can advise you on whether to replace or repair. At times, an advanced upgrade proves to be money-saving in the long run.
