Selekshɔn Gayd fɔ PTFE Ay-Tɛmpratura Tep fɔ Demolding & Anti-Stik Aplikeshɔn fɔ Injɛkshɔn Molding Mashin dɛn

Jiangsu Aokai Nyu Matirial, we na profeshɔnal manifakta fɔ PTFE ɛn fluoroplastic prodak, de sheb di sɛlɛkshɔn krayteria fɔ PTFE ay-tɛmpracha tep fɔ dimoldin ɛn anti-stik sɛnɛriɔ pan injɛkshɔn mold ikwipmɛnt.

I. Tεmprachכ-Bεys Sεlεkshכn: Fכkus pan Hεt Rεsistεns fכ Adhesive Layer εn Sabstεrayt

PTFE tep gɛt tu pat: sabstret (jɛnɛral fayv glas fabrik we dɛn kɔt wit PTFE) ɛn bak adhesive. Di adhesive layt kin bi di pefomans botlɛn.

1. Kɔntinyu fɔ ɔpreshɔn tɛmpracha ≤ 260°C (Jɛnɛral plastic & pat pan injinɛri plastic)

Di matirial dɛn we dɛn kin yuz: PE, PP, PS, ABS, sɔft PVC, EVA, ɛn bak PA, PBT ɛn ɔda matirial dɛn we dɛn kin prosɛs na di tɛmpracha rɛnj dɛn we smɔl. Rikɔmɛnd sɛlɛkshɔn: Standart fayv glas-rɛinfɔs PTFE tep wit silikon prɛshɔn-sɛnsitiv adeziv (PSA). Tik we dɛn se: 0.13 mm ɔ 0.18 mm, we de balans kɔnfɔmabiliti ɛn savis durabiliti. Ki not dɛm: Dis na di optimal wok rɛnj fɔ PTFE tep, we gɛt fayn fayn kemikal stebiliti ɛn rilis pefɔmɛns.

2. Kɔntinyu fɔ ɔpreshɔn tɛmpracha 260°C ~ 300°C (Hay-tɛmpracha injinɛri plastic)

Di matirial dɛn we dɛn kin yuz: PC, PA66, POM, PET, ay-tɛmpracha PPA, modifyed PPO ɛn ɔda ay-tɛmpracha injɛkshɔn mold dɛn. Rikɔmɛnd sɛlɛkshɔn: Fayba glas PTFE tep we dɛn fɔmulayt wit ay-tɛmpracha rɛsistɛns silikon adeziv. Ɔdinari silikon adeziv go ol kwik kwik wan, i go lɔs tackiness ɛn lɛf rɛsɛdyu ɔnda dis tɛmpracha rɛnj. Tik we dɛn se: 0.18 mm ɔ 0.25 mm. Tik adhesive ɛn sabstret layers de deliver bɛtɛ thermal buffering ɛn wear resistance. Kritikal kɔnfɔmeshɔn: Spɛsifik adhesive sistem dɛn wit lɔng tɛm tɛmpracha rɛsistɛns ɔp 280°C to saplay dɛn, ɛn chɛk if di adeziv go kɔntamin mold dɛn ɔnda ay ɔt.

3. Instant pik temperechur 300°C ~ 400°C (Spɛshal ay-tɛmpracha plastic ɔ lokal hot ples)

Di matirial dɛn we dɛn kin yuz: PEEK, LCP, PPS, PEI, we dɛn kin fɛn mɔ nia hot rɔna noz ɛn pat pan di ɛkstrushɔn day ed dɛn. Selekshɔn wɔnin: No prɛshɔn-sɛnsitiv adeziv we pɔsin kin abop pan nɔ go ebul fɔ bia wit dis tɛmpracha rɛnj. Ɛni PTFE tep we gɛt adeziv bak go fel wantɛm wantɛm, i go gɛt kabɔn ɛn kɔntamin di prɔdak dɛn we dɔn dɔn. Ɔda we dɛn fɔ sɔlv di prɔblɛm:

1. PTFE fayv glas fabrik we nɔ gɛt adhesive, we dɛn kin fiks wit mashin bay mold klem frem, strip ɔ ay-tɛmpracha strɔkchɔral adeziv (adhesives we nɔ gɛt prɛshɔn lɛk silikon silin).

2. Fusible ful fluorinated PFA film tep, we dɛn ataya to mold surfaces via hot air welding. I de tinap fɔ kɔntinyu 260°C ɛn fɔ shɔt tɛm 300°C, bɔt stil dɛn nɔ kin ebul fɔ riples am fleksibul wan lɛk sɛlf-adhesive tep. Optimized alternative proposal: Fɔ dis kayn ay-tɛmpracha kɔndishɔn, mold PTFE kɔtin ɔ nano sɛramik ay-tɛmpracha rɛsistɛns kɔtin na mɔ rɛkɛmɔnded.

II. Material Property-Based Selection: Match Wear Resistance, Kɔrɛshɔn Rɛsistɛns ɛn Rilis Rikwaymɛnt

Fizik ɛn kemikal prɔpati dɛm fɔ molten plastic de ditarmin di rikwayd sɔfayz funkshɔnaliti ɛn strɔkchɔral trɛnk fɔ di tep.
