Beauty brands "snag up" pulp-molded packaging? Unpacking the "middlemen" in this sector
Pulp molding sounds "simple" - isn't it just pouring the pulp into the mold and pressing it?
This is the biggest misunderstanding in the industry.
In actual production, the real technical difficulties are densely distributed in:
Slurry formula
Ratio of long and short fibers, addition of additives, and concentration control
Poor matching → cracking during molding, surface fuzzing, insufficient strength
Mold Design
Flow channel layout, exhaust hole position, demolding slope
Poor mold quality → uneven wall thickness, tensile fracture, yield rate below 70%
vacuum adsorption
Negative pressure curve, multi zone pressure control, uniformity of slurry distribution
Poor suction → Local material shortage, thickness difference>0.3mm
Hot pressing and shaping
Uniformity of temperature field, holding time, and mold opening speed
Poor compression → deformation, sticking to the mold, yellowing of the surface
Production line rhythm
Multi mode alternation, automatic pick-up, online drying
Slow → bottleneck of production capacity, fast → loss of quality control
Each of these five stages is a deep pit of 'know-how'.
At present, there are only a few equipment manufacturers in the world that can provide a full chain solution of "slurry formula+mold design+whole machine integration+production line debugging".
Foshan Meishi Machinery is one of the most noteworthy companies.
