PP (Polypropylene) profile te hi a rit lo va, corrosion-resistant, leh high-strength plastic products te hi construction, automotive, leh home appliance application-a hman lar tak a ni. A siamnaah hian step hrang hrang a tel a, raw material buatsaih, mixing, extrusion molding, cooling leh shaping, pulling leh cutting, leh post-processing te pawh a tel. Step tin hian final product quality-ah hmun pawimawh tak an chang a ni.
Raw material buatsaih leh mixing .
PP profile siamna atana hmalakna hmasa ber chu raw material buatsaih a ni. High-purity polypropylene resin hi a tlangpuiin thlan a ni a, impact modifier, UV absorbers, leh colorants te ang chi additives remchang tak tak te chu product performance mamawh dan azirin an dah tel bawk. Heng raw materials te hi uluk taka screen leh dried a ni a, chu chuan extrusion laiin bubble leh surface defect awm loh nan 0.02% aia hniam a moisture content a awm theih nan a pui a ni. Chumi hnuah chuan raw material leh additives te chu high-speed mixer-ah uluk takin an inhmeh tir a, chu chuan uniform dispersion a tichiang a ni.
Extrusion molding 1000 a ni.
Mixed raw materials te chu hopper kaltlangin -screw emaw twin-screw extruder pakhatah an kal a, chutah chuan temperature sang tak (a tlangpuiin 180{4}}220 degree) leh pressure sang tak hnuaiah an melt a, plastic an siam a ni. Screw rotation chuan melt chu hmalam pan turin a nawr a, die kaltlangin duh duh profile cross-section-ah a siam a ni. Mold design hi a pawimawh hle a, profile-a dimensional accuracy leh a lan dan direct-in a nghawng a ni.
Cooling, shaping, leh drawing te .
Molten PP profile chu mold atanga extrude a nih hnuah chuan cooling leh shaping device (vacuum setting table emaw water tank emaw ang chi) ah a lut nghal a, rang taka a lum leh a solidify theih nan. Cooling rate hi internal stress concentration leh deformation awm loh nan khauh taka control a ngai a ni. Chumi hnuah chuan profile chu puller hmangin speed constant-in an la chhuak a, chu chuan dimensional stability a tichiang a ni.
Cutting leh post-processing .
A mamawh angin profile chu automated cutting machine hmangin a sei zawng tarlan angin a cut a. Thil siam ṭhenkhat chuan hmanna tur bik mamawh phuhruk nan surface treatment (polishing emaw printing emaw ang chi) emaw assembly emaw a ngai bawk.
PP profile siam chhuahna process, stage tina parameters te uluk taka control hmanga, mechanical property tha tak leh durability a awm theih nan, tunlai plastics processing technology-a thil pawimawh tak a ni.
