Everyone knows more or less about plastic dustbin mould. Most of the trash cans on the market are mainly made of plastic, but making plastic dustbin mould is not a simple process, especially demoulding.

After the plastic part is injection-molded, the plastic part is ejected from the cavity of the mold, whether it is a single or multi-element ejection mechanism, the demolding work is generally completed at one time. But sometimes due to the special shape of the plastic part or the need for automatic production, after a demolding work is completed, the plastic is still difficult to take out from the cavity or cannot fall automatically. At this time, another demolding action must be added to make the plastic part. Fall off. Additives such as oily hydrocarbons or water are mixed into the sintered powder. The additives decompose during sintering and then escape along the gap of the mold wall. This is good for obtaining a complete sintered part and improving the life of the mold. This saves the process of secondary demolding.

For plastic box mold , adding additives during demolding can also make demolding more convenient.
