The Importance of Clamping Force in Injection Moulding – Explained by Hydroking Industries
In the world of plastic injection moulding, precision is everything. One of the most critical yet often overlooked elements in achieving that precision is clamping force. Without the proper clamping force, even the most advanced injection moulding machine can fall short of delivering consistent, high-quality parts.
At Hydroking Industries, we believe that understanding clamping force is key to optimizing your production process. Here, we break down why it matters, how it's calculated, and how our machines are engineered to deliver the perfect balance of force, speed, and safety.
💡 What is Clamping Force?
Clamping force is the pressure applied by the machine to keep the two halves of the mould tightly shut during the injection process. It's crucial because molten plastic is injected at high pressure, and any weakness in the clamping could lead to:
- Flash (plastic leakage from the mould)
- Part deformation
- Machine damage
⚖️ How is Clamping Force Calculated?
The required clamping force depends on:
- The projected area of the moulded part (in cm²)
- The injection pressure (in kg/cm²)
Formula:
Clamping Force (tons) = Projected Area × Injection Pressure ÷ 1000
For example, if the projected area is 200 cm² and the pressure is 300 kg/cm²:
Clamping Force = (200 × 300) ÷ 1000 = 60 tons
🏋️ Why is Clamping Force So Important?
- Prevents Flashing
Too little force allows molten plastic to leak, causing part defects. - Maintains Mould Alignment
Proper force ensures both mould halves stay perfectly aligned during injection. - Enhances Part Quality
Stable clamping helps maintain part dimensions and finish consistency. - Reduces Downtime
Correct force prevents mould damage, reducing machine maintenance and repair costs.
