The image above represents co-efficient allowing for friction. To calculate co-efficient allowing for friction, two essential parameters are needed and these parameters are Friction Co-efficient of the Gating System (μ1) and Friction Co-efficient of the Mould (μ2).
The formula to calculate co-efficient allowing for friction:
μ = μ1 x μ2
Where the following applies:
μ = Co-efficient allowing for Friction
μ1 = Friction Co-efficient of the Gating System
μ2 = Friction Co-efficient of the Mould
Let’s solve the following example:
Find the co-efficient allowing for friction when the friction co-efficient of the gating system is 10 and the friction co-efficient of the mould is 14.
This implies the following:
μ1 = Friction Co-efficient of the Gating System = 10
μ2 = Friction Co-efficient of the Mould = 14
So, μ = μ1 x μ2
μ = 10 x 14
μ = 140
Therefore, the co-efficient allowing for friction is 140.
Calculating the Friction Co-efficient of the Gating System when the Co-efficient Allowing for Friction and the Friction Co-efficient of the Mould are Given
μ1 = μ / μ2
Where the following applies:
μ1 = Friction Co-efficient of the Gating System
μ = Co-efficient allowing for Friction
μ2 = Friction Co-efficient of the Mould
Let’s solve the following example:
Find the friction co-efficient of the gating system when the co-efficient allowing for friction is 45 and the friction co-efficient of the mould is 15.
This implies the following:

μ = Co-efficient allowing for Friction – 45
μ2 = Friction Co-efficient of the Mould = 15
Then, μ1 = μ / μ2
μ1 = 45 / 15
μ1 = 3
Therefore, the friction co-efficient of the gating system is 3.

Calculating the Friction Co-efficient of the Mould when the Co-efficient Allowing for Friction and the Friction Co-efficient of the Gating System are Given
μ2 = μ / μ1
Where the following applies:
μ2 = Friction Co-efficient of the Mould
μ = Co-efficient allowing for Friction
μ1 = Friction Co-efficient of the Gating System
Let’s solve for the following example:
Find the friction co-efficient of the mould when the co-efficient allowing for friction is 50 and the friction co-efficient of the gating system is 25.
This implies the following:
μ = Co-efficient allowing for Friction = 50
μ1 = Friction Co-efficient of the Gating System = 25
So, μ2 = μ / μ1
μ2 = 50 / 25
μ2 = 2
Therefore, the friction co-efficient of the mould is 2.
