Explain the details of the conventional process of silicone sealing strip processing!silicone snack cup manufacturer

　　Industrial sealing references, conventional electronic components, daily silicone products, etc. are used in countless places where silicone strips are used. Silicone rubber material has special physiological inertness, so it can achieve adaptability in any environment and special circumstances, so many consumers My friend has some doubts about the material and processing technology of the silicone rubber sealing strip, and does not know about the production process and the characteristics of the material, so what is the detailed processing process?

　　Both the silicone tube and the silicone strip are strip-shaped products, which can be produced in several different processing methods for the production process. Both solid silicone and liquid silicone can be used side by side. Its performance is excellent, mainly high and low temperature resistance. Good physiological inertia can be used normally under different environmental conditions, long-term use does not affect the strength of deformation and rebound, and it has excellent resistance to ozone, ultraviolet rays and aging, and green environmental protection has no conflict with any substance. normal performance, no need to worry!

　　Silica gel strip extrusion production process:

　　1. Rubber mixing: The raw materials for mixing rubber are mixed with double-24 or platinum vulcanizing agent or silica gel masterbatch in a double-stick rubber mixing machine, and pressed into a layer of uniform thickness of silica gel extruded material.

　　2. Extrusion molding: install the mold on the head of the silicone extruder. The compounded rubber is divided into shapes of the same size and length, which is convenient for feeding from the inlet of the extruder. Then feed through a silicone extruder, extrude a very soft silicone hose, put the silicone hose into an 8-meter long drying tunnel, and vulcanize it at high temperature. The silicone hose coming out of the drying tunnel can be semi-finished, and then wrapped.

　　3. High temperature vulcanization: Put the wound silicone hose into the oven, the ordinary silicone is 180 degrees, the gas-phase silicone hose is 200 degrees, and the high temperature is 2 hours, and the secondary vulcanization is performed to remove the odor on the silicone hose, prevent frosting and change yellow.

　　4. Follow-up processing: the rest is to carry out follow-up processing such as cutting or bonding according to the length required by the customer. Then pack and ship to customers as required.

　　Silicone tube strip forming and molding production process

　　1. Rubber mixing: pure transparent silica gel raw materials are mixed and processed, and the two-component vulcanizing agent and color rubber are added for mixing. After passing the size specifications of the product, the same size is cut out with a knife for molding at high temperature!

　　2. Molding: Put the cut silicone raw material into the mold core, and directly press it to achieve the shape through high-temperature solid-state molding. Among them, the silicone strip manufacturer needs to pay attention to the quality control of the product, such as unripeness, bulging and other phenomena.

　　3. Trimming treatment: The silicone strip is processed by upper and lower mold clamping, and there will be burrs at the part of the mold clamping line, so manual trimming, mechanical beating or freezing trimming are required for appearance treatment.

　　4. Matters needing attention, both the silicone tube and the silicone strip belong to the sealing or assembly function similar to the silicone sealing ring, so the performance and tensile force of the product need to be strictly controlled.
