You need to pick the right belling machine for your needs. Think about your production goals, budget, and what you want to use it for. Every factory has its own problems. Your choice depends on how you want to work, how fast you need things done, and what tools you have.
You will see a simple comparison that helps you choose with confidence.
Belling Machine Differences
Operation
Manual machines need two people to run them. One person puts the pipe in the heating station. The other person moves the pipe to the belling station. You have to pick up each pipe by hand. These machines do not use a chain convey system. Semi-automatic machines mix manual work with some automatic parts.
You control some steps, but a touchscreen helps you go faster. A programmable logic controller also makes things easier. Automatic machines use a chain convey system. They move pipes through each step by themselves. The table presents the main differences at a glance.
| Type of Belling Machine | Operational Mechanism |
| Manual | Needs two people; you feed and stack pipes by hand. No chain convey system. |
| Semi-Automatic | You load pipes at some steps; touchscreen and PLC help control the process. |
| Automatic | Everything is automatic; chain convey system moves pipes for you. |
Tip: If you want to work with long pipes or need steady results, automatic machines work best.
Efficiency
Think about how many pipes each machine can make in one hour. Manual machines make 60 to 120 pipes every hour. Semi-automatic machines make 150 to 250 pipes per hour. Automatic machines make 300 to 500 pipes per hour. Some big machines can make up to 800 pipes per hour. The kind of pipe material also changes how fast you work.
PVC pipes work best with double screw extruders. These use less heat and skip extra steps. PP pipes need more heat and careful work so they do not get damaged.
| Machine Type | Average Output (pcs/hr) |
| Manual | 60–120 |
| Semi-Automatic | 150–250 |
| Automatic | 300–500 |
| Large Diameter | 500–800 |
| Material | Extruder Type | Processing Form | Efficiency Characteristics |
| PVC | Double Screw Extruder | Dry Blend | Pumps work better, less heat needed, skips granulation, cleans itself. |
| PP | Single Screw Extruder | Granular | Needs more heat, can get damaged, uses friction for steady output. |
Note: If you want to make lots of pipes fast, automatic machines are the quickest.
Cost
You should think about how much money you want to spend. Manual machines cost less at first, but you pay more for workers. Semi-automatic machines cost more but help you work faster. Automatic machines cost the most at first, between $7,300 and $7,350. Save on workers, produce more pipes. Many people buy automatic machines because they work well and cost less over time.
- Manual: Cheapest to buy, but you pay more for workers.
- Semi-Automatic: Costs a medium amount, helps you work faster.
- Automatic: Most expensive, good for making lots of pipes.
Tip: If you have a small shop, manual or semi-automatic machines may be best for your budget. If you have a big factory, automatic machines save money in the long run.
Skill Required
Each machine needs different skills to run. Manual machines need two skilled people. One person works the heating station. The other person works the belling station. Semi-automatic machines need basic technical skills. You use a touchscreen and PLC. Automatic machines need less work from you. You just watch the process and check things sometimes.
- Manual: Two people, hands-on skills needed.
- Semi-Automatic: Basic technical skills, some manual work.
- Automatic: Little manual work, easy to watch and check.
Note: If you want to spend less time training and save money on workers, automatic machines are the easiest to use.
Pros and Cons

Suitability
When to Choose Manual
Pick a manual belling machine if you make fewer pipes. You get more control over each pipe you make. Manual machines work well in plumbing, automotive, and HVAC jobs. These jobs need exact fittings and custom work. You can set up a manual machine fast. It is easy to switch pipe sizes or shapes. Manual machines cost less to buy. Small businesses and workshops like this. You can start working right away. Manual machines are not good for big factories. They cannot make enough pipes for high demand. If you want to be flexible and spend less money, manual machines are a good choice.
Tip: Use manual machines for small batches, custom fittings, or when you want to save money and keep control.
When to Choose Automatic
If you have a big factory or need lots of pipes, automatic belling machines are best. These machines produce many pipes quickly while maintaining quality. You can trust them to make strong joints and waste less material. You can use automatic machines across multiple pipe types and project requirements. You need fewer workers, and the process is easy to watch. The machines cost more at first, but you save money later. You pay less for workers and make pipes faster.
| Advantage | Description |
| Strong joints | Pipes connect well and do not leak. |
| Increased output | Machines make more pipes for big orders. |
| Consistent quality | Every pipe is made the same way. |
| Versatility | Machines work with different materials and sizes. |
| Minimized waste | Pipes are shaped well, so less material is lost. |
| Enhanced performance | Pipes are strong and last longer. |
