Introduction

Plastic dustbin are a necessity in daily life, regardless of the occasion.

We can categorise plastic dustbin based on their intended use into household dustbin and industrial dustbin.

Household dustbin are classified into three styles: rotating dustbin, pedal dustbin, and simple dustbin(round, square) . These sizes are generally available in 1L, 5L, 10L, 15L, 20L, and 25L .

Industrial dustbin are typically wheeled, because of their large capacity and ease of transport. In general, industrial dustbin come in the following sizes: 20L, 40L, 50L, 60L, 120L, 240L, 360L, 650L, 1000L, and 1100L.

Whether it is a household dustbin or an industrial dustbin, as long as it is a plastic dustbin, it will generally be made of environmentally friendly PP. We can use environmentally friendly PP to create a bright surface, then laminate the printing and other processing to create high-quality, beautiful, and functional plastic dustbin.

However, it is not easy to produce a high quality plastic dustbin, provided that a high quality plastic dustbin mould is manufactured. Plastic dustbin mould production is extremely demanding, from mold design and assembly to runner selection, all of which must be strictly controlled one by one.

The key points of designing a dustbin mould

Depending on the use scenario (at home or in a factory), the plastic dustbin have to be strong enough. Therefore, when designing and manufacturing molds, it is important to ensure that the plastic products produced can be stacked under weight and will not be bent or deformed.

In addition, according to the specific design requirements of the product, the design of the mold should consider and increase or decrease the reasonable demold draft and make the corresponding anti-deformation treatment; under the condition of ensuring the quality, the rib can be added appropriately, which not only facilitates the release of the mold, but also saves part of the cost; meanwhile, the reasonable and sufficient rounding design is also conducive to the release of the mold and increase the strength.
