1、 What does injection grade PFA pipe mean?
Injection grade PFA pipe, as the name suggests, refers to PFA pipes produced using injection molding technology. PFA is a high-performance perfluoroalkoxy resin material with extremely high chemical corrosion resistance, high and low temperature resistance, low friction coefficient, excellent electrical insulation performance, and good transparency.
2、 Is the production of PFA pipes generally using injection molding or extrusion technology?
The production process of PFA pipes generally adopts extrusion technology. For example, trifluoride is produced using extrusion molding technology, which is the standard method for manufacturing PFA pipes.
This process involves feeding PFA resin raw materials into an extruder, heating the resin to melt, and under the push action of the screw, forming a continuous tubular product through a specially designed mold.
Extrusion molding can achieve precise control of the wall thickness, outer diameter, and other dimensions of PFA pipes, while ensuring their stability and consistency during the production process.
Injection molding technology is usually suitable for manufacturing plastic parts with complex structures, diverse shapes, and small batches. For example, PFA joints use injection molding technology, which is generally not used for non continuous length pipes. PFA pipes are more suitable for manufacturing using efficient and continuous extrusion processes due to their continuous length and relatively simple cylindrical structure.
3、 What is the price range for PFA tubes?
The price of PFA tubes varies due to factors such as their specifications, wall thickness, length, and purchase quantity. Generally speaking, the unit price of PFA tubes may be slightly higher than that of ordinary PFA tubes because it involves more complex production processes and technical requirements, while also considering the high purity of the raw materials themselves and strict production control.
In addition, the price fluctuations of PFA tubes in the market are influenced by various factors such as international raw material prices, market demand, brand effects, and supply-demand relationships. Normally, the price range of PFA tubes may range from a few hundred to several thousand yuan per kilogram, and the specific price needs to be inquired in detail based on the actual product parameters and market conditions purchased.
