Portable force measurement device for preventive maintenance on injection molding machines

Injection molding machines can produce waste when both halves of the mold are not parallelly closed.

Injection molding machines can produce waste when both halves of the mold are not parallelly closed. Additionally, wear occurs on the mating surfaces. These problems can develop whenever the closing force distribution in the four tie-bars of the injection molding machine is uneven.
These forces are measured with mobile strain measurement equipment and can be directly displayed in newtons when the diameter and modulus of elasticity of the tie-rods have been included in the calibration of the measurement chain.

Uneven force distribution can be corrected by means of adjustments to the tie-rods. In this way damage to production equipment is effectively prevented by easily handled mobile measurement equipment.
