The early steps in setting the plastic injection molding machine

Here I will describe the basic way of setting or setting the product for plastic injection machine. Aside from that, perhaps you also need to check out the recommended injection mold manufacturer China.

The first one set the barrel temperature according to the data sheet material (MSDS) until the temperature is reached. Check the mold compliance, circulation cooling, and mold conditions to be set.

Clean the cores and cavity surfaces from anti-rust with a clean cloth. When cleaning the mold please note if the mold uses a slider. Often the slider is accidentally knocked and causes the home slider’s position to change. This can result in the slider colliding with the angular pin so that the angular pin is broken or bent.

After the core and cavity surfaces are cleaned from anti-rust then we proceed with the mold close and mold open mold.

What needs to be considered in the closed mold setting, open is the construction of the mold and position limit switch speed switch and high limit switch position. The basic rule of setting up close mold is close high-speed mold —-> close shutdown & lowpass mold ——> mold close high press.

The position of the low press limit switch is positioned as follows 2.5 cm before the angular pin or guide pin goes into the bushing limit switch must be touched. This is necessary so that the print time closes there is no hard collision between cores and cavity.
For setting the high press position for temporarily empty first.

After we adjust the speed as well as the limit distance of the switch to mold close with the construction of mold we continue with the open mold setting.
Open mold setting is opposite of mold close ie open slow mold —– +> mold open high speed —–> mold-open slow —– +> open stop.
the basic rule is 2cm after the guide pin or angular out of open high-speed bus limit mold switch is untouched.

Then we set the open mold position stop. The opening width of the mold is at least 2 X length of product + runner length.
