Clamping Force and Precision

When you pick a sole making machine, clamping force is very important. Most machines for new shoes use 200 to 400 tons of clamping force. Many machines made for soles use about 250 to 300 tons. This strong force keeps the mold tight and still. It stops the mold from moving and keeps the sole good.

A high clamping force helps make each sole the same. The mold stays steady, so every sole has the right thickness and details. Good machines, like ones from HONLED, let you control the clamping pressure very well. This makes sure every time you use the machine, the force is just right. Because of this, the soles work well and meet tough quality rules.

Injection Capacity and Material Range

Injection capacity tells you how much material goes in at once. Machines often have screw diameters of 45, 50, or 55 mm. They can hold between 275 and 420 cm3 of material. These sizes work for many kinds of soles, from light shoes to heavy boots.

The injection rate is usually about 180 cm3 per second. A faster rate means you can make more soles quickly. The machine can inject up to 400 grams of material at one time. You can use many materials like TPR, TPU, PVC, and foaming compounds.

It is important that the machine works with many materials. For example, a PVC TPR sole moulding machine can use different thermoplastics. It can also use foaming and non-foaming types. This lets you make soles that grip well, last long, or feel light. Being able to use many materials makes these machines good for all kinds of shoes.

Automation and Control Systems

New sole making machines use smart automation and control systems. These include PLC controls, touchscreens, and robots. You can set the machine to do each step just right. This cuts down on mistakes and makes every sole the same.

Automation helps you work faster. A fully automatic machine can make up to 1,200 pairs of shoes each day. This is because the machine opens, injects, cools, and removes the soles by itself. Automation also means you need fewer workers, so your team can do other jobs.

Control systems watch and change things like heat, pressure, and speed as you work. This keeps the process steady and helps make better soles. There is also a smart mold protection system. It stops damage and helps your molds last longer, so your machine works well for a long time.

Energy Efficiency and Maintenance

Energy efficiency is now a big part of new sole making machines. New machines use servo motors, closed-loop control, and energy-saving parts. Servo motors give strong power but use less energy. Closed-loop systems keep pressure and flow steady, which helps the machine work better.

These features save energy and lower your bills. They also help you make shoes in a way that is better for the planet. You can reach your green goals and still make lots of shoes.

Taking care of your machine is important for saving money over time. If you clean and check the molds and parts often, you stop problems before they start. Good maintenance keeps your machine running well. This helps you make more shoes with the same high quality your business needs.
