Sometime ago I received this question from one of Vega’s distributor and at first I thought it was an easy answer, but then I realised that others also were not aware of this small but important detail.
Let’s start with an example, lets consider now the VEGA V450CM block or compact cylinder and on its catalogue at page M4 there is a chart (here is the link to V450CM catalogue).
This chart is made…

Mould Cycle Time vs Cylinder Speed
Mould Cycle Time vs Cylinder Speed
Normally, in an Injection Mould Cycle, the Hydraulic Cylinders start operating during Closing and Opening. As common practice, Mould Users squeeze cycle operation to the minimum possible, for saving time and, therefore, money. The drawback may be a higher stress on the components and an increased requirement for maintenance. Therefore, the right balance must be found.
Below, we report some…

Choosing the right Cylinder for Mold Core: Aluminium vs Steel Body
Choosing the right Cylinder for Mold Core: Aluminium vs Steel Body
We would like to introduce a new factor in choosing the best cylinder for your application, that is, the differences between Aluminum Alloy and Steel block cylinders.
In fact, each of them has its own pros and cons, so we feel that a comparison table referring to Vega products may be useful.

Choosing the right Cylinder for Mold Core: Stroke
Choosing the right Cylinder for Mold Core: Stroke
The stroke of a hydraulic cylinder is the distance covered by the piston and rod between the full-in and full-out positions.
It can be found as the difference between the maximum extended length of the hydraulic cylinder and its minimum retracted length. In Vega cylinders, stroke is part of the code and can be found on the nameplate.
Basically, in a cylinder catalogue, three values are given:…

Choosing the right Cylinder for Mold Core: Pushing Force
1) Projected Area of Molded Part
The real surface of the molded part is the area in contact with the molten plastic. Naturally the Plastic Part has a complex design, and obviously the pressure will act perpendicularly to each bit of surface element. The force we are interested in, is only the part acting along the cylinder rod. The other forces acting on the part and resulting from the injection…
