In the plastics world, if you’re doing extrusion or injection molding, wear and tear can sneak up on you and really hurt your bottom line.Because companies are using more reinforced stuff to keep up with today’s industry needs, their machines are really working harder than ever.
When you’re working with abrasive plastics on your production line, a typical Nitrided screw barrel usually just isn’t going to cut it.At Shreeji Corporation, we think Bimetallic Screw Barrels are a really good solution when things get worn down a lot.This is why your business really needs them.
1. It’s tough dealing with abrasive fillers.
Manufacturers often mix in stuff like Glass Fiber, Carbon Fiber, Calcium Carbonate ($CaCO_3$), or Flame Retardants to make plastic products stronger and more resistant to heat.
Those additives might make the product better, but they really chew up the insides of your machines.A regular screw barrel will wear down pretty fast, and when that happens, you’ll see a few things go wrong:
- Less stuff came out.
- The melt quality isn’t consistently good.
- Breaking down all the time, and it costs a ton of money.
2. Superior Material Composition
A bimetallic barrel has two types of metal. The part that handles the friction is made of a different, harder alloy. It helps with wear and tear, especially for things like injection molding. A bimetallic barrel differs from a standard one because it has an alloy lining inside, added through a centrifugal casting process.
At Shreeji Corporation, we make our bimetallic components with high-grade tungsten or cobalt-based alloys.These alloys offer excellent wear resistance, making them a very good option for situations where parts experience a lot of rubbing. The hardness level is much higher than what you get from regular nitriding.
3. Precision and Consistency Over Time
In precision molding, even a few microns of wear on the screw flight can ruin a batch. To prevent this, we’re using a specific type of steel for the screw flight that should hold up better. This change is something we believe will improve our product consistency. Bimetallic screw barrels hold their size for a much longer time.
- Even Melting: Maintaining a consistent gap between the screw and barrel helps keep pressure steady, which is important for quality.
- Less waste: Less waste is a real benefit. When the screw doesn’t wear out, you avoid that pulsing, uneven flow that leads to defective parts. It’s a simple change that makes a big difference.
4. Cost-Effectiveness in the Long Run
Many businesses hesitate because of the initial cost of bimetallic parts. The Total Cost of Ownership is much lower.
When you’re processing 30% glass-filled nylon, a bimetallic barrel actually gives you 3 to 5 times the operational life compared to a nitrided barrel.
A worn screw takes more energy to keep pressure.Maintaining your components properly will help you see a reduction in your monthly electricity costs.
5. Corrosion Resistance for Special Plastics
When heating PVC or similar plastics that contain halogens, corrosive gases are released.Bimetallic barrels are designed to stop chemical damage. This prevents the pitting that causes material to get stuck and create black spots in your finished products.
