How to apply mold cleaning agent to plastic injection molds

Recently, due to its adorable appearance and the influence of the Winter Olympics, the Chinese mascot "Bing Dwen Dwen" has become incredibly popular, leading to a situation where it is difficult to find one. To make a "Bing Dwen Dwen", one must first create an injection mold for the plastic outer shell! The outer shell of Bing Dwen Dwen is made of silicone material. To mass produce Bing Dwen Dwen silicone toy shells, a precise injection mold must be created. Before the mold manufacturing process, mold core puller lubricant must be applied, and a series of mold cleaning agent cleaning processes are required.

Five Steps in the Production of Bing Dwen Dwen Toy Shells

01 Bing Dwen Dwen silicone material toy outer shells are injection molded products. The specific production process of molded silicone rubber products generally involves heating the silicone rubber raw material in a closed mold cavity; then injection molding is performed under pressure, and after cooling, demolding yields a silicone product. In the factory's production workshop, as long as the raw materials are in place, the Bing Dwen Dwen outer shell injection mold can be quickly produced. However, the Bing Dwen Dwen silicone material toy shell specifications are relatively large, differing from other small commodities where one mold can produce dozens of products. One set of Bing Dwen Dwen injection molds can only produce 2 toy shells at a time. With one machine operating continuously, two sets of injection molds can only produce a maximum of 800 toy shells per day.

02 Small Silicone Material Toy Shells Overcome Many Difficulties

Some people may think that the production process of Bing Dwen Dwen silicone material toy shells is not very difficult, and that after the sample product is confirmed, it can be completed as scheduled. However, sample production and mass production are two different things. To achieve mass production of Bing Dwen Dwen silicone material toy shells, silicone rubber product manufacturers need to overcome the following two major difficulties in order to produce toy shells with the ice shell texture.

Difficulty 01: Unfamiliar with Silicone Rubber Products

Unfamiliarity with silicone rubber products leading to small air bubbles is one specific cause of product defects. The specific reason is the inconsistent processing time, and the demolding time being too short when rushing to complete. The reason for the appearance of small air bubbles is improper material placement or insufficient venting frequency, causing air to be trapped in the mold cavity, and the air in the mold cavity not being fully discharged. This situation must be resolved by adjusting the machine's demolding time and the processing method of the machine's venting.
