How We Turn Silicone Into Reliable Products
We support customized silicone products from mold design and material selection to mass production and final quality inspection.
- Manufacturing Process
Orderly Manufacturing Process
Silicone tubing production starts with raw materials. We choose silicone of different grades—food grade, medical grade, or industrial grade, according to your needs. Before production, we test and blend the materials to ensure proper purity, hardness, and temperature resistance.
The silicone raw material is mixed with additives and color masterbatch to improve durability and achieve the desired color. After that, the core process begins—extrusion. The silicone goes through a high-precision extruder and forms into tubes of different sizes. During this step, we keep tight control of the inner and outer diameters as well as the wall thickness to ensure accuracy.
After forming, the silicone tubing goes through high-temperature vulcanization. This step stabilizes the molecular structure of the material, giving it better elasticity and stronger resistance to heat and aging. Once vulcanized, the tube holds its shape more reliably and delivers stable performance over time without easily deforming.
After vulcanization, the silicone tube cools quickly and is cut to the required size. Depending on the application, some tubes receive additional surface treatments before shipment. Each piece then goes through strict testing, including visual checks, dimensional measurements, hardness tests, and resistance tests for temperature and pressure. These steps make sure every batch of silicone tube meets high quality standards.
There are differences between silicone tube and silicone hose in structure, performance and use. The choice should be based on the specific application.
The silicone tube is usually a single layer. It has a homogenous wall for an overall good wall thickness and concentricity. Features Inner Diameter, Outside Diameter and Length accuracy. Flexible and holds its shape, making it ideal for precision conveying applications. Most silicone hoses are a multi-layer structure. Always with a fiber braid or wire braid. Their use is characterized by pressure resistance, camber resistance and high strength. Withstand bending and pressure in tough applications. Applicable to medium and high pressure conditions and can bear stronger streets.
If you need high dimension, transparency and cleanliness in your application and the pressure of the fluid is low, the silicone tubing is appropriate.If you require high-pressure and flex resistance, and the product may be subject to frequent movement or mechanical stress, then silicone hoses are a better choice. In other words, knowing your application and fluid environment is paramount to ensuring you make the right choice and selecting the appropriate silicone product for you.
Our silicon tubing is used in a wide range of industries. In the medical sector it is often found in ventilation catheters, IV tubes, instrument sampling tubes and other tools. It provides safe, accurate, and contamination free fluid delivery. In the food processing field, silicone tubes are often used for coffee machines, drinks delivery , etc. Food grade silicone tubes can be used in various food machinery and food contact products. The material meets FDA or LFGB standards to guarantee that food will stay safe and healthy. In laboratories and automated industry, silicone tubing is widely used as fluid delivery and fluid carrying tubing. Stable and reliable experimental data are guaranteed. Silicone tubing is also popular in the electronics industry.
Rinse the tube directly after use with warm water to prevent any remaining liquid or particles from drying. Cleaning with a mild neutral detergent or special disinfectant dedicated to medical or food use. Use no chemical products containing chlorine or strong acid or alkali solutions. These can harm the silicone. Brush the inside of the tube while cleaning. Rinse and let it air dry or wipe it with dust free cloth. Boiling sterilization is ok. The heating should not be more than 230°C.
