Fix the stationary mold to the stationary platen and movable mold to the movable platen with bolts.
There are various methods to fix molds, such as direct fixing with bolts, using clamps, using T-slot bolts and nuts, using an automatic clamping device, and using a magnetic clamping device.
Mold fixing with bolts or clamps
Give sufficient consideration to the maximum mold opening force and nozzle touch force, and maintain proper bolt size, number of bolts and threaded depth. Fixing bolts should have threaded depth 1.5 times the bolt diameter as shown in the table below. Tighten fixing bolts occasionally not to allow loosening in operation.

[13] Remove the wire lifting the mold.
