How to Increase the Life of a Plastic Injection Mould
A plastic injection mould is one of the most valuable investments in plastic manufacturing. A well-made mould can produce thousands or even millions of plastic products. But just like any machine or tool, it needs proper care.
If you maintain your mould correctly, it will give you better product quality, fewer production problems, and lower maintenance costs.
At Hattrix Mouldcraft, we believe that a quality mould and proper maintenance go hand in hand. Our moulds are built using precision engineering, quality steel, and advanced manufacturing processes for long-lasting performance. (Hattrix Mould craft)
Why is Mould Maintenance Important?
Many manufacturers only pay attention to a mould when it stops working properly.
This can lead to:
- Production delays
- Poor product quality
- More rejected parts
- Higher repair costs
- Shorter mould life
Regular maintenance helps avoid these problems and keeps production running smoothly.
1. Clean the Mould Regularly
After every production cycle or production batch, clean the mould properly.
Remove:
- Plastic residue
- Dust
- Oil
- Moisture
- Carbon deposits
A clean mould produces better-quality plastic parts and reduces defects.
2. Keep Cooling Channels Clean
Cooling channels help reduce cycle time by cooling the plastic evenly.
If these channels become blocked:
- Cooling becomes slower.
- Production takes more time.
- Product quality may reduce.
- Mould temperature becomes uneven.
Cleaning cooling channels regularly improves production efficiency.
3. Use the Right Plastic Material
Always use the plastic material recommended for your mould.
Using the wrong material may:
- Increase wear on the mould
- Damage the surface finish
- Reduce mould life
- Cause product defects
Always check the material specifications before starting production.
4. Lubricate Moving Parts
Some mould parts move every production cycle.
These include:
- Guide pins
- Slides
- Lifters
- Ejector pins
Proper lubrication reduces friction and helps these parts move smoothly.
Never use too much lubricant, as excess oil can affect product quality.
5. Check for Wear and Damage
Inspect the mould regularly.
Look for:
- Scratches
- Cracks
- Rust
- Loose parts
- Worn ejector pins
- Damaged inserts
Finding small problems early can prevent expensive repairs later.
6. Store the Mould Properly
If the mould is not being used, store it in a clean and dry place.
Before storage:
- Clean the mould completely.
- Apply anti-rust oil.
- Cover the mould to keep out dust.
- Keep it away from moisture.
Proper storage protects the mould and keeps it ready for the next production run.
7. Use the Correct Machine Settings
Incorrect machine settings can put extra pressure on the mould.
Always use the correct:
- Injection pressure
- Holding pressure
- Injection speed
- Cooling time
- Clamping force
Correct settings improve product quality and reduce unnecessary stress on the mould.
8. Replace Worn Parts on Time
Some mould components wear out naturally after long use.
Replace damaged parts before they affect production.
Common replacement parts include:
- Ejector pins
- Springs
- Bushes
- Guide pillars
- O-rings
Replacing small parts on time can prevent major mould damage.
9. Schedule Preventive Maintenance
Do not wait for the mould to fail.
Create a maintenance schedule based on:
- Production cycles
- Number of shots
- Product type
- Material used
Preventive maintenance helps avoid unexpected machine stoppages and keeps production running smoothly.
