Liquid silicone rubber foaming products harsatna chinfel nan chuan a bulpui ber atanga siam solution systematic a ngai a ni .
Core Philosophy: Invenna hi siamthat ai chuan a tha zawk. Harsatna tam zawk hi "mihring, machine, material, method, leh environment"-a thil pangaa thununna hloh atanga lo chhuak a ni. Chuvangin, solution pawh hi heng aspect panga atang hian systematic takin approach a ni tur a ni.
Liquid silicone rubber foaming atana solution approach hian "formula" leh "process" inkara balance dik tak a ngaihtuah zawk a, a bik takin foaming leh vulcanization speed inmilna lam a ngaihtuah zawk a ni.
一.Cell structure issues (a inang lo, open leh closed cell ratio, pore size)
1.Fmula (material) - Hei hi a pawimawh ber a ni: Balance of foaming agent leh vulcanizing agent: Experiment (DOE) hmangin, foaming agent-a decomposition temperature/rate leh vulcanizing agent reaction rate inkara inmilna tha ber zawng rawh. A tha ber chu bubble a zau tan chuan rubber compound viscosity chu a sang tawk hle a, mahse a la vulcanized kim lo a ni.
2.Nucleating agents hmang rawh: solid particle tha tak tak (Titanium dioxide, zinc oxide ang chi) te dah la, bubble atan uniform nucleating point tam tak a awm ang a, chu chuan cell structure tha leh inang tlang tak a hmu ang. Base adhesive viscosity siamrem: Viscosity dik tak thlang rawh. Viscosity a sang lutuk chuan bubble te chu a lo thang harsa dawn a; A hniam lutuk chuan bubble te hi an inzawm khawm duh hle.
2. Lei chung quality chungchangah (roughness, skinning) .
1.Adjusting the mold temperature (Method) : A chung lamah bubble emaw roughness emaw a awm chuan: mold temperature a sang lutuk a, a chunglam layer chu nasa tak leh a rang thei ang bera foam a ni thei. Mold temperature chu a remchan dan anga tihhniam tum emaw, cold runner system hmangin rubber compound chu mold-ah temperature hniam takah a lut thei ang.
2.Skin thickness control: vun siam a ngaih hunah chuan mold temperature sang zawk hmang la, chu chuan surface layer chu mold nena inzawm a, foaming tel lovin a vulcanize rang thei ang. Vun nem leh hring a mamawh hunah chuan mold temperature hniam zawk hmang ang che.
3,density deviation leh shrinkage deformation .
1.Precise Injection (Machine, Method) : High-precision metering mixing injection machine hmangin mold tin tan injection volume error chu a tlem thei ang bera hman theih a ni. Injection volume hi a tlangpuiin product volume atanga 60% atanga 80% vel a ni a, experiment hmanga chiang taka hriat a ngai. 2.Thudik tak leh uniform vulcanization (Method) enkawl a ngai : mold area tin temperature chu uniform heat distribution a awm theih nan calibrate rawh. Vulcanization time chu tizau la, product central part pawh fully vulcanized a nih leh nih loh enfiah la, post-shrinkage tihtlem rawh.
3.Ejection leh cooling (Method, Machine) optimize : Product a demold zawh chuan deformation awm loh nan cooling atan shaping fixture (fixture) hmang ang che. Ejector pins awmna leh a quantity chu optimize la, product chu a chhuak thei ang a, a eject thei ang a, a eject thei ang.
