PVC fittings are a common pipe connection material, widely used in construction, chemical and agricultural applications. So, how is PVC pipe fitting produced? And how should its raw materials be selected?
First of all, let’s take a look at the production process of PVC fittings, which is divided into four main steps: preparation of raw materials, mixing and preparation, extrusion and subsequent treatment.
Prepare the raw materials
The first stage is the preparation of the raw material. At this stage, high-quality polyvinyl chloride (PVC) resin is selected as the main raw material for pvc fittings, and appropriate amounts of stabilisers, plasticisers and other auxiliary additives are added according to product requirements.
Mix preparation
The next step is the mixing and preparation process. The selected PVC resin and various additives are placed in a high speed mixer in a certain proportion for thorough mixing and homogeneous blending to ensure that every part of the pvc fittings is in an ideal state.
Extrusion process
Then comes the extrusion process. The molten PVC, prepared by mixing, is injected into the extruder and extruded through the die at high temperature and pressure. pvc fittings extruder pushes the molten material inside the die and makes it solidify rapidly through the cooling system.
Subsequent processing modifications
Finally, there is the subsequent processing step. These include trimming, grinding and cleaning to ensure the quality of the PVC fittings’ appearance and dimensional accuracy.
Summary
As mentioned above, the production process of PVC fittings consists of four steps: preparation of raw materials, mixing and preparation, extrusion and subsequent treatment, and factors such as resin quality and additives need to be taken into account when selecting raw materials. Through scientific and standardised production operations, high quality fittings can be obtained, providing better pipe connection materials for all industries.
