What are the steps in the processing of plastic steel profiles?

Plastic steel profiles have inherent advantages as an energy-saving insulation material. Non-metallic materials have poor heat transfer capabilities, which makes plastic steel profiles have lower heat transfer coefficients. It is easy to achieve low thermal conductivity when making windows and doors. It is an ideal energy-saving insulation material. Jinan plastic steel profile manufacturer - Jinan Lumei Construction Material Co., Ltd. shares with you the production and processing technology of plastic steel profiles.

Due to the use of plastic steel profiles with low thermal conductivity, plastic steel windows have significant cost advantages in achieving high environmental protection and energy saving effects. In places such as Northeast China, where the weather is cold, in order to achieve better environmental protection and energy saving effects, a large proportion of plastic-steel windows are used, and the market share of plastic-steel windows is very high. The window is equipped with more than 70 cavity pvc profiles, with three glass and two hollow LOWE laminated glass, and three sealing systems. The thermal conductivity of the entire window can easily reach 1.5W/m²·K, even if it is a passive window 0.8W/ The m²·K value is also relatively easy. Because plastic steel windows can achieve high environmental protection and energy saving characteristics at a relatively low cost, plastic steel windows still occupy a certain sales market.

How are plastic steel profiles produced? The production of plastic steel profiles goes through the entire process of seasoning, mixing, extrusion, cooling and shaping, traction belt cutting, testing, and packaging. Plastic steel profile is a kind of hard polyethylene polymer plastic that first undergoes the seasoning process. After the R&D department determines the secret recipe, the seasoning process will complete the work. The seasoning process includes automated production lines and is also performed manually. The secret recipe is composed of more than ten raw materials such as PVC, halogen-free flame retardants, fillers, lubricants, processing aids, light stabilizers, and color pastes. There are special regulations for each raw material and cannot be abused.

Polyethylene wax is a common raw material. There are two types of polyethylene wax: rutile type and anatase type. The rutile type cannot be used, and the anatase type is not allowed. The anatase type is cheap, but it is manufactured. Pvc profiles are very prone to June black. Due to environmental protection requirements, the secret recipe must use heavy metal-free halogen-free flame retardants to meet environmental protection and health requirements. In the mixing stage, various raw materials that have been measured and verified according to proportion are added to the mixer in a certain order. Pay attention to the order of feeding, which affects the quality of the mixture. The field of plastic steel profiles overseas is relatively complete, and there are professional companies producing mixtures. In China, most of these aspects are full-process manufacturing, and there are no companies that specialize in selling mixed materials in the market. The feeding order of each raw material affects the quality. The time, temperature and speed of the mixer in the mixer will also affect the quality of the mixture. If a company lacks technical capabilities, the essential quality of its products cannot be effectively guaranteed.

The mixed materials go through the extrusion production line to form products. The extruder is an important production line equipment. There are many types of extruders: single-screw extruders and single-screw extruders; the types of twin-single-screw extruders are divided into conical single-screw and parallel-plane single-screw. . Choose a suitable single-screw extruder according to different requirements. The basic principle of a single-screw extruder is to use external heating and the shear stress of the extruder screw on the raw material to melt the polyethylene PVC pellets and change them into a molten state. The completely melted polyethylene material passes through the mold to form a certain shape, and then enters the vacuum setting mold, where it is cooled by cooling water to form a certain shape. The profile is continuously pulled out of the material tube through the tensile force of the cable pulling machine, and then reaches the fixed-length cutting process, and is cut into profiles of a certain length, usually 6 meters in length. After the mold is heated, pay attention to tightening the high-strength bolts.
