Maintaining your mold clamps is essential for their durability. It would help if you kept them clean, free of dust, debris, and other contaminants.

They should be checked for cracks, breaks, dried grease and oil, and any other damage.

The adjustment knobs should also be checked to ensure that they are tight enough to hold the mold clamp firmly in place as it moves up or down the rail as required by the mold movement as it is made.

If not, properly maintained mold clamps will deform the part, damage themselves and even introduce impurities into the product. With proper care and attention, mold clamps can last a long time and function very efficiently.

16. What are the Ways to Find Out Clamping Pressure in Mold Clamps?

A clamping pressure in mold clamps refers to the amount of force required to hold a mold in position permanently. Mold clamping pressure has a great effect on part cost and plastic injection molding machine output.

Clamping pressure should be balanced between the forces which force the plastic into all crevices and cavities of a mold and those which pull a hardened, cured plastic part from a mold.

To determine the clamping pressure the process, including the following steps:

  • Calculate the area of the particular product
  • Length of flow is referred to as a distance between mold gate to the extreme edge
  • The thickness of the particular product
  • How many cavities exist in the Mold

When the above factors are determined, you only need to insert their values into the formula and thus calculate your clamping pressure.

Clamping pressure in mold clamps is important as it helps to expand the depth of the cavity and increases surface contact.

It is one of the most fundamental reasons for retaining dimensional stability and simplifying making injection molds.
