Production Method for Silicone Rubber Tube Extrusion Equipment

2021-05-31

There are many types of rubber hoses, and silicone rubber hoses are one of them. Based on their structure, silicone hoses can be divided into single‑extrusion hoses and composite hoses. Single‑layer hoses have a relatively simple manufacturing process; during production, we select an appropriate rubber extruder model according to the product’s size. However, since silicone rubber is quite soft, we typically do not use conveyor belts to transport the products during manufacturing. Therefore, the silicone rubber extruder must be elevated during operation. When producing silicone rubber hoses, the die head needs to be designed specifically for each product. For example, when manufacturing single‑layer silicone hoses, we usually employ a T‑die configuration, allowing the extruded rubber to flow vertically downward. A vertical hot‑air vulcanization chamber is then installed directly beneath the die to cure the product. Under gravity, the hose remains free from contact with any surface during vulcanization, thus preventing surface scratches. Because silicone rubber cures readily, the required length of the vulcanization chamber is relatively short. For this reason, elevating the silicone rubber extruder provides an effective solution for curing the finished products.

Silicone rubber tube extruder During production, the die head must be designed according to the specific product. For example, when manufacturing single‑layer silicone tubing, we typically use a T‑die to extrude the rubber, with the extruded tube moving vertically downward. We then mount a vertical hot‑air vulcanization oven directly beneath the die to cure the product. Under gravity, the tube remains free of contact with any surfaces during vulcanization, thereby preventing surface scratches. Silicone is highly vulcanizable, so the required length of the vulcanization oven for silicone tubing is relatively short. Consequently, we can elevate the silicone extruder to facilitate the vulcanization process.
