What is Mold Clamp?
Mold clamp tools definition
What is mold clamp? The mold clamp (also called mould clamp) is a kind of auxiliary clamping
unit often used in injection mold processing, its main function is to keep the machined parts not
shaking not moving in the processing.
What is mold clamp used for?
Mold clamp for the mechanical workpiece fixation of various solid bodies on a work plate or
holder. Mostly the mold clamp is used for plastic injection molding machinary and CNC
machinery.
Why mold clamp is so important?
The quality of the mold clamp directly affects the quality of the mold. The mold clamp plays a
vital role in the mold manufacturing process. We need to ensure the accuracy and good finish of
the mold workpiece. The mold clamp has high strength, small size, flexible and easy to operate.
What is mold clamp made of?
Mold clamp is made of long lasting through-hardened steel.

Mold clamp is forged from 45# medium carbon steel and quenched at high temperature to reach
35HRC to 40HRC as required by JB, and finally the surface is blackened or blued to achieve the
purpose of no rust.
These mold clamps are used for injection molding industry. These are useful for clamping of
molds on plastic injection molding machines.
What is mold clamp feature?
High speed to change and fix your mold;
Varied mold clamp sizes with M10, M12, M14, M16, M18, M20, M24, M30 mold clamp specs;
The mold clamp material is harded and more tough. Not easy to bend and eliminates the
fracture;
Made of long-lasting through-hardened steel;
Appreciated for quality, corrosion resistance, and high durability;
Reasonal mold clamp price;
Mold clamp bolts are adjust to different mold clamp thicknesses.
Easy to install and equip with self-adjustable mode.
What is mold clamping unit?
The mold clamping units are used to keep the injection mold shut against the forces developed
when injection pressure pushes plastic into the closed mold.
Therefore, the amount of mold clamping force must be at least equal to the amount of injection
molding force. The machine sizes are determined by the clamping tonnage forces.
What is mold clamp force?
The mold clamp force refers to the force applied to an injection mold by the clamping unit mold
clamp of an injection molding machine. In order to keep the injection mold closed, this clamping
force must oppose the separating force, caused by the injection of molten plastic into the
injection mold.
The mold clamp force rating is stated in tons, e.g. a 400 ton machine is capable of producing a
maximum clamping force equivalent to a total of 400 tons.
The mold clamp force calculation tonnage can be used to select a capable machine that will
prevent part defects, such as excessive flash.
What injection mold clamp tonnage calculation is required?
The required mold clamp force can be calculated from the cavity pressure inside the mold and
the shot projected area, on which this pressure is acting.
There are variables that affect the mold clamp force calculation, like the material type (low-flow
or high-flow plastic), and the depth of the part.
What is clamping pressure?
Clamping pressure is a measurement of the mold clamp force needed to hold the injection mold
closed during injection. If this clamping pressure is not set high enough, the injection mold will be
forced open prematurely by injection molding pressure and will create flash on the related
molded part.
