How are silicone straws made in the market? Silicone straw color is very beautiful, in the past should be introduced in cups, bottles and other aspects, now in many countries to launch the "ban on plastic law" determination and give up the background of plastic straw, silicone straw slowly become a popular product, many enterprises are using silicone straw, so how to make silicone straw? The principle of silicone straw extrusion is divided into raw material preparation, glue practice, extrusion, vulcanization, secondary vulcanization and back-end processing. These steps can be used for the finished product of food grade silicone straws. At present, the company uses platinum vulcanization technology to produce silicone straws, which are non-toxic to other raw materials, have no peculiar smell, have no harm to human contact, are environmentally friendly, and are easy to decompose and drain. There are 7*9,6*8,7*10,8*10,8*11 and so on. This is common in the market, except for molded silicone straws.

At present, molded silicone straws, that is, silicone bending tubes (40 ° 60 °), can only be used in the extrusion process to achieve regular extrusion, while irregular silicone straw products, such as silicone bending straws, as long as they are divided into preparation, rubber training, Mold heating and mechanical molding need to be manufactured with molds. Need to cooperate with large sheet metal mold manufacturing (need mold opening fee), molding silicone straw does not need to cut, other secondary processing can save some costs, but its beauty is not as good as silicone extrusion straw (with mold line).
