Wiwit panyiapan Fangli wis dikembangake adhedhasar pangguna panjaluk. Liwat dandan terus-terusan, R&D independen ing inti teknologi lan pencernaan & panyerepan teknologi canggih lan liyane tegese, kita wis dikembangakégaris ekstrusi pipa PVC, PP-R pipe extrusion line, pe saluran pasokan banyu / pipa gas ekstrusi, sing disaranake dening wong Tionghoa Departemen Konstruksi kanggo ngganti produk impor. Kita wis entuk gelar saka "Brand kelas kapisan ing Provinsi Zhejiang".

apa iku Plastik Extrusion?

Ekstrusi plastik, also known as plasticating extrusion, is a continuous high volume manufacturing process in which a thermoplastic material -- in a form of powder, pellets or granulates -- is homogeneously melted and then forced out of the shaping die by means of pressure. In screw extrusion, the pressure comes from the screw rotation against the barrel wall. As the plastic melt passes through the die, it acquires the die hole shape and leaves the extruder. The extruded product is called extrudate.


Carane Apa Proses Ekstrusi Bisa?

resin

Proses ekstrusi plastik diwiwiti kanthi apa sing diarani resin termoplastik. Resin termoplastik minangka jinis plastik sing bisa dilebur, diolah, banjur dilebur maneh kanggo digunakake maneh. Resin iki umume dikirim ing bentuk pelet utawa manik kanggo digunakake ing mesin ekstrusi plastik.

Pelet utawa manik bisa teka ing pirang-pirang macem-macem wujud. Ana manik resin plastik, sing teka ing apa sing diarani dadi wujud prawan. Iki minangka manik-manik sing durung tau diproses sadurunge lan umume teka karo sertifikasi kemurnian. Manik-manik uga kasedhiya ing gelar kualitas sing bisa dituku kanggo nggunakake tartamtu. Sampah plastik saka proses ekstrusi bisa diolah maneh dadi manik-manik sing bisa digunakake maneh, kang nyuda sampah sakabèhé kui ing proses.

Mesin lan Leleh

Mesin ekstrusi bisa rumit operate, nanging proses sakabèhé relatif suta. Jantung saka mesin punika meneng, kang kadhangkala diarani minangka auger. meneng diuripake dening gearbox, kang powered by motor. Iku ditutupi ing nyenyet, tong minyak digawe panas, kang mbantu kanggo nyedhiyani gesekan.

The thermoplastic pellets are delivered into the machine through a hopper. The hopper is located at the rear of the barrel/screw assembly and the pellets drop into the barrel from there. As the screw turns, it slowly drags the thermoplastic pellets forward. The heat from the friction of the screw turning inside the barrel–along with external heating–melts the plastic as it moves forward in the barrel. The melted plastic is pushed into a section designed to meter the plastic for the next stage in the process. It also may be subjected to pressurized pumping at this phase of the process.

Ekstrusi

Sawise plastik wis mlebu metering bagean saka tong minyak, iku siap kanggo extruded menyang die. Mati iku ditempelake ing tong minyak lan nggantosi wangun final utawa profil sing plastik dimaksudaké kanggo njupuk. Plastik dipeksa menyang die. Minangka plastik gerakane maju menyang die, iku bakal dipisahake dening mandrel a, kang dipusatake ing saluran ekstrusi.

Pressurized online dipeksa sanadyan ing struktur mandrel minangka liya kanggo njaga plastik saka ambruk nalika gerakane liwat mati. Minangka plastik ninggalake mati, bakal mlebu ing vakum lingkungan. Ing vakum, ana dering ukuran sing dimaksudake kanggo njaga plastik ing wangun sing dikarepake. Lingkungan vakum uga bakal diisi banyu minangka sarana kanggo cooling plastik extruded. Sawise plastik extruded wis liwati liwat lingkungan vakum banyu-nepsu bisa Cut utawa spooled minangka cocok.
