Long-term cost reductions through the use of a hot runner system |

Resources, plastic granulate included, become ever more valuable. With the use of a cold runner system there are inevitably high costs due to the unusable sprue. It is precisely these costs that must be avoided for more efficient production. Using a hot runner system saves on the cost of the unusable material. You can use our sprue cost calculator to calculate how much material costs could be saved in the injection moulding process.

Other advantages of a hot runner system

Scarcity of raw materials and price increases in plastic granulate impact considerably on efficiency in production. By using a hot runner system, decisive application advantages can be achieved that have a positive impact on productivity. Although hot runners are often associated with higher procurement costs, there are many other technical and financial aspects that make them preferable to cold runners.

Technical perspective

Shorter cycle times, as sprues usually have to cool down for longer
Reduced loss of pressure
Improved holding pressure effect
Positive impact on shrinkage and warping
Injection from the inside possible
Potential to use stack moulds

Financial perspective

No sorting of runners required
No storage of runners required
No regranulation required
Less space required for the same production volume
