In the automotive sealing strip industry, most of the sealing strip products are mainly soft PVC (hardness range is HA50-HA85). Since the glass transition temperature of PVC resin is about 75°C, it is particularly sensitive to temperature changes, and it is very brittle when the temperature is low. Therefore, for automotive PVC seal manufacturers, it is imperative to improve the cold resistance of
PVC plastic transparent sealing strip is different from ordinary sealing strip production line The production process of PVC plastic transparent sealing strip extrusion is different from the production process of ordinary sealing strips. The production process of ordinary PVC plastic sealing strips is granulated first, and then extruded, while the PVC plastic transparent sealing strips are It is
Introduction of production process of plastic sealing strip Single extrusion plastic seal production process is nothing more than two kinds, one is the extrusion production of ordinary plastic seals, and the other is the extrusion and production of transparent seals. The production of ordinary plastic sealing strips is made of plastic particles. The plastic extruder plasticizes the plastic pa
Plastic advertising edging equipment The advertising word sidebar we call is also called a luminous word sidebar, which is a type of plastic composite product. During production, we usually call the plastic extruder that produces this product as an advertising word sidebar extruder or a luminous word. Edge strip extruder. When we produce luminous characters, we must first adjust the raw
How rubber shields are produced There are two types of shields that are common to us. One is pure black single-extruded rubber shields. This product often requires only one rubber extruder to produce it. We need to choose the rubber extruder model suitable for production according to the size of the product. For example, the 120 type rubber extruder and 90 type rubber extruder that we c
How are plastic seals produced PVC plastic sealing strips are very common among the sealing strips. Generally, plastic sealing strips can be divided into two parts for extrusion production during production. One part is to produce raw materials into the plastic particles we need according to the quality of the product. The second part is to extrude the product through plastic pellets. S
Precautions for plastic seals Now the function is getting worse and worse. The aging mechanism is not the opposite. Among them, thermal (light) oxygen aging is a common and fundamental way of aging EPDM seals. 1. Fatigue aging Fatigue aging of EPDM sealant strips means that the molecular structure of EPDM sealant strips undergoes changes under the influence of certain frequency and periodic s
Problems that should be paid attention to in the production of plastic sealing strip equipment For the production method of plastic seals, according to the production process, usually granulate first, and then use a plastic extruder to extrude the plastic particles into the products we need, so that the finished seals can be obtained. In the manufacturing process, we must pay attention to th
