Dosing
The amount of material needed to carry out the moulding and filling process of the cavities to be injected.
Cylinder temperature
This refers to the temperature required to melt the material and to keep it melted until production of a new part begins.
Mould temperature
It is important to control the total cycle time, as well as the correct fluidity of the raw material to be injected. The controlled mould temperature also enables effective control in cycle time reduction and effective cooling time.
Cooling time
The necessary waiting time for the raw material to cool down correctly in the cavity, thereby enabling crystallisation to take place correctly and allowing for extraction to take place free of any deformities. It must be defined taking into account the thickness of the product to be produced, the properties of the materials used, and the temperature of the mould.
Injection time
This refers to the time it takes for the material to fill all the cavities of the mould.
Injection pressure
Pressure is applied to the plunger of the injection moulding machine in order to push the plastic into the mould cavities. The pressure applied should be as low as possible, taking into account the specifications of the raw material.
Injection speed
This is calculated by taking into account the amount of melted material being used and the time it takes to fill the mould cavities. The higher the speed, the less time the filling process takes.
These are just a few of the variables related to the injection moulding process that have a significant influence on the final properties of the products being manufactured. Therefore, they must be carefully adjusted according to the customer’s requirements.
