Thread protector with seamless steel pipe steel pipe PE gas pipe fittings and other products are constantly updated now the product variety is increasing. Now the major pipe manufacturers must use plastic pipe cap to protect the pipe mouth, which is also a new change in our industry. It is necessary to increase more varieties and specifications of plastic pipe cap to meet customer needs.
The working principle of plastic cap injection molding machine is similar to the syringe used for injection. It is the process of injecting the plastic into the closed mold cavity with the help of the thrust of the screw (or the plunger), and obtaining the products after solidification and shaping
Injection molding is a cycle process, each cycle mainly includes: quantitative feeding - melt plasticizing a pressure injection a mold cooling a mold take. After taking out the plastic part, the mold is closed again for the next cycle.
After molding, extrusion and other pre-processing in the factory, with leftover materials or unqualified mold products in the secondary processing plant to prepare the thermoplastic. Thread protectors in many standards of recycled plastic limited to clean plastic use, it is satisfied with the requirements of new material rules, and its product quality is actually equivalent to the product made from new material. Thread protector manufacturers are here to remind you that it can not be recalled for reprocessing use of a class of plastic.
