1-What is PVC sealing strips<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

PVC sealing strips<\/strong>\u00a0are made of polyvinyl chloride (PVC) as the main raw material, with plasticizers and other ingredients added. They have heat resistance, toughness and ductility, and are mainly used in the door and window, furniture, automobile and curtain wall manufacturing industries. Its production process includes raw material preparation, mixing, extrusion molding and other links. The microwave vulcanization process can improve the surface finish and elasticity. The applicable temperature range is -40\u2103 to +120\u2103.<\/p>

High-quality products are identified by their characteristics such as not softening at high temperatures and not breaking easily at low temperatures. When burned, they emit black smoke and leave hard residues. The density is 1.4-1.6; inferior products often have poor elasticity and are prone to aging and shrinkage due to excessive talcum powder filling. Silicone rubber sealing strips have a wider temperature resistance range (-50\u2103 to 200\u2103), burn smokelessly and odorlessly, and have a lower density (1.1-1.25) [1]. This product supports customized services and can meet the needs of scenarios such as insect control and sound insulation<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

\u00a0At Shuowei, we\u2019ve refined our service architecture over 20 years and 3,000+ global projects to transform complex profile challenges into competitive advantages. Here\u2019s why manufacturers from Munich to Mumbai trust our rigorously engineered process.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\t

Customization process:<\/strong><\/p>

1. Contact us: Clarify the purpose of PVC sealing strips<\/strong>, if you have specific requirements specifications\uff0cplease send an email or WhatsApp to contact us(<\/strong><\/span><\/a>+86 188 2072 7151<\/span><\/a>)<\/strong><\/p>

2. Prepare Raw Materials: According to the purpose and performance requirements of the extruded profiles, PVC or PE ABS PP PMMA raw materials with different polymerization degrees and models can be selected.<\/p>

3. Extruder preheating: The heating device heats each section of the extruder barrel to the set temperature. Generally, the material is divided into the feeding section, compression section and metering section, and the temperature of each section is different.<\/p>

4. Extrusion molding:Add the mixed dry blend into the preheated extruder barrel. As the screw rotates, the material is transported forward in the barrel. Finally, under the action of the die, the designed shape is extruded.<\/p>

5. Cooling & Shaping: The PVC sealing strips<\/strong>\u00a0extruded from the extruder head has a high temperature and needs to be cooled and shaped immediately to maintain its shape. Usually a vacuum sizing water tank is used for cooling and shaping.<\/p>

6. Sample testing: If the sample test is qualified, a batch order will be placed. If it is unqualified, the sample will be remade.<\/p>

7. Mass production: Sign a bulk purchase and sale contract.After confirming the samples, the production stage will be entered. The printing quality (such as ink dots and registration deviation) and die-cutting accuracy will be monitored.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
