Product features
Production Process of Sintered PE cap
UHMWPE powder is selected and mixed with plasticizers, stabilizers and other auxiliary materials.
The mixture is filled into the mold and pre-pressurized mechanically to form a preliminary shape.
Heating in three stages (low-temperature pre-molding → medium-temperature sintering → high-temperature strengthening), the temperature is controlled at 110-130 ℃ (lower than the melting point of PE), so that the powder particles are fused and bonded to form a porous structure.
After demolding, cut to the required length and install the joints (e.g. M20, M30 thread).
Conduct bubble uniformity test, compressive strength test and chemical compatibility test.
