How is the silicone seal formed?

Forming method of silicone sealing strip: First, the actual operating staff add epoxy curing agent to the plastic pellets according to the secret recipe, and then put the silicone into the vulcanized rubber scouring machine to mix and cut into strips, the total width of which generally does not exceed the extrusion molding. The overall width of the machine inlet. When the extruder is started, the cooling circulating water valve is opened, and the vulcanized rubber strip is naturally fed from the mandatory feeding equipment to the extrusion molding barrel. According to the rotation of the extruder screw, the sealing rubber strip is moved to the direction of the engine. During the whole process of fitness exercise In the process, the polymer material is manipulated within the temperature range specified by the processing technology (adjust the power switch of the cooling circulating water valve) to make it shrink and plastically deform. Because of the function of the extruder screw, the plastic pellets have the function of close extrusion during the production process, so that the product structure is integrated with each other, the relative density is increased, the circulation is stable, and the product quality of the silicone sealing strip is good.

Advantages of silicone seals: 1. Silicone itself has a strong inertial force, so the round silicone rubber seals have excellent aging resistance and corrosion resistance. The surface can be divided into smooth and granular, the temperature range is -70-300 degrees, and the color tone can be customized and matched, which is in line with environmental certification The surface has the functions of anti-vibration, moisture-proof and anti-fouling. 4. Environmental protection safety of solid round silicone rubber sealing strip: non-toxic and odorless, belongs to food-grade stainless steel sealing strip, and can be safely used in food and medical device industries. 5. The solid core circular silicone sealing strip has small shrinkage and small deformation, strong resilience, good surface non-stickiness, good air permeability, and smooth and beautiful surface.
