1. The screw length-to-diameter ratio of the medical silicone tube extruder is 10:1. The compression ratio is 2.5:1. The screw is a floating type with unequal distance and unequal depth, which can be easily pushed out by hand. The rubber material or cleaning does not produce any rubber material waste and pollution, which is unique in China.

2. The machines all use variable frequency motors and are equipped with Japanese original Fuji inverters. The minimum tolerance can be plus or minus 0.01mm, and the product wall thickness can be less than 0.05mm. Our company's extruders all have the function of two-color extrusion. The rubber material is of 2 colors, so 2 extruders are needed (up to 3 machines can be co-extrusion, that is, products with 3 colors are produced).

The extruder is equipped with automatic feeding device, stepless speed regulation, uniform and stable operation, no manual operation, completely solved the inconvenience of manual forced feeding to production operation and product size.

Our company's extruders currently mainly include 90, 65, 50 and 35 types. Generally, domestic manufacturers of industrial products purchase 65 machines + 6 + 0.8 meters of curing tunnel.

The screw diameter of the 65 type silicone extruder is 65mm, the normal production capacity can reach 150 kg/hour (depending on the product size), and the motor power is 11 kilowatts. The size range of products produced by the 65 model is relatively wide. If equipped with an enlarged die sleeve, the maximum diameter can be about 120mm, and the minimum can produce products under 2mm.

The screw diameter of Type 50 silicone extruder is 50mm, the normal production capacity can reach 80 kg/h (depending on the product size), and the motor power is 7.5 kilowatts. The size range of the products produced by the 50-type machine is 2-45mm. If equipped with an enlarged die sleeve, the maximum diameter can be about 70mm, and the minimum can produce products below 2mm.

3. The two-stage vulcanization tunnel completely solves the problems of product indentation and roundness. The specifications of the drying tunnel are 8.5 meters, 6.5 meters or 4.5 meters. The pre-vulcanization section is 0.5 meters, the stretch vulcanization section is 4 meters, 6 meters, 8 meters, the maximum temperature of the pre-vulcanization section (front section) is 700 degrees, and the maximum temperature of the stretch vulcanization section (back section) is 500 degrees. Under normal circumstances, the production speed of the drying tunnel can exceed 20 m/min (depending on the product size). The maximum power of the 8.5-meter drying tunnel is 32 kilowatts, and the maximum power of the 6.5-meter drying tunnel is 24 kilowatts. The maximum power of the 4.5-meter drying tunnel is 18 kilowatts.
