Product Detail Product Tags APG mold Production flow chat: Application: instrunment transformer apg mold used for produce current transformer from 11-36Kv: Epoxy resin current transformer Casting process by APG molding machine: Step 1: install Current transformer APG Mold on APG clamping machine Step 2: install accessories,inserts into APG mold. Step 3:Clamping apg machine,injection epoxy resin into mold. Step 4:Epoxy resin curing inside mold,open clamping plate,take out product. 2 cavities current transformer apg mpld Mold material:P20 Hardened In order to improve the life of the mold to more than 800,000 mold times, the pre-hardened steel can be quenched and low temperature return The hard way of fire to achieve. When quenching, preheat at 500-600°C for 2-4 hours, then keep it at 850-880°C for a certain period of time (at least 2 hours), then put it in oil and cool to 50-100°C and air cooling. After quenching, the hardness can reach 50. -52HRC, in order to prevent cracking, 200℃ low temperature tempering treatment should be carried out immediately, after tempering, the hardness can be maintained above 48HRC Nitriding treatment Nitriding treatment can obtain high hardness surface structure, the surface hardness after nitriding reaches 650-700HV (57-60HRC) The service life of the mold can reach more than 1 million times. The nitride layer has the characteristics of dense and smooth structure, and the mold release performance and resistance to humid air and alkali corrosion are improved. Delivery status: The steel is delivered in annealed and hot rolled state. Material characteristics ● Uniform hardness, good polishing performance and photo-etching performance, good processing performance. ● Vacuum degassing and refining process pure steel, suitable for plastic molds that require polishing or etching. ● Supplied in a pre-hardened state, it can be directly used for mold processing without heat treatment, shortening the construction period. ● After forging and rolling, the structure is dense, 100% ultrasonic inspection, no pores, pinhole defects.

Pojedinosti o proizvodu Oznake proizvoda Razgovor o tijeku proizvodnje APG kalupa: Primjena: instrumentni transformator apg kalup koji se koristi za proizvodnju strujnog transformatora od 11-36Kv: Strujni transformator od epoksidne smole Postupak lijevanja APG strojem za oblikovanje: Korak 1: instalirajte APG kalup strujnog transformatora na stroj za stezanje APG-a Korak 2: instalirajte pribor, umetnete u APG kalup. Korak 3: Stezanje apg stroja, ubrizgavanje epoksidne smole u kalup. Korak 4: Stvrdnjavanje epoksidne smole unutar kalupa, otvorite steznu ploču, izvadite proizvod. 2 šupljine strujni transformator apg mpld Materijal kalupa: P20 Stvrdnuo Kako bi se život kalupa poboljšao na više od 800.000 puta kalupa, prethodno kaljeni čelik se može ugasiti i vratiti na niske temperature Težak put vatre za postizanje.Prilikom gašenja zagrijati na 500-600°C 2-4 sata, zatim držati na 850-880°C određeno vrijeme (najmanje 2 sata), zatim staviti u ulje i ohladiti na 50-100°C. C i hlađenje zrakom.Nakon kaljenja, tvrdoća može doseći 50. -52HRC, kako bi se spriječilo pucanje, potrebno je odmah provesti tretman kaljenja na niskoj temperaturi od 200℃, nakon kaljenja, tvrdoća se može održavati iznad 48HRC Tretman nitriranjem Obrada nitriranja može dobiti strukturu površine visoke tvrdoće, površinska tvrdoća nakon nitriranja doseže 650-700HV (57-60HRC) Vijek trajanja kalupa može doseći više od milijun puta.Nitridni sloj ima karakteristike guste i glatke strukture, a poboljšana je učinkovitost otpuštanja kalupa i otpornost na vlažni zrak i alkalnu koroziju. Status isporuke: Čelik se isporučuje u žarenom i toplo valjanom stanju. Karakteristike materijala ● Ujednačena tvrdoća, dobre performanse poliranja i performanse foto-jetkanja, dobre performanse obrade. ● Vakuumski proces otplinjavanja i rafiniranja čisti čelik, pogodan za plastične kalupe koji zahtijevaju poliranje ili jetkanje. ● Isporučuje se u prethodno očvrslom stanju, može se izravno koristiti za obradu kalupa bez toplinske obrade, skraćujući razdoblje izgradnje. ● Nakon kovanja i valjanja, struktura je gusta, 100% ultrazvučna kontrola, bez pora, rupica.
