The process is generally used for manufacturing large small hollow articles .Most of the products is made for LLDPE /HDPE. Polyethylene in powder form is poured into a sheet metal mould "arm" powder by motors that slowly rotate or spin it biaxially in an oven at 250-300 c, with the charge of powder inside the mould. After the entire quantity of powder is consumed and fully melt-sintered, the mould is allowed to cool. This causes the polymer to solidify and shrink, thereby de-attaching itself the polymer to solidify and shrink, thereby de-attaching itself from the mould walls. The molded article can then be easily removed by opening the mould .And the piece is ready to sell.
Hollow seam Less parts - totally enclosed or with openings.
Uniform wall thickness - strong corners.
Excellent load bearing properties - virtually stress free parts.
Design flexibility - from small & intricate to large & complex.
The ability to produce multi wall moldings.
Economical tooling cost - 50 to 80 ° less mold cost compared to other moldings.
Economical for short production runs & prototypes as well as volume production.
Short lead - time, less time for launching the product in the market.
Products designed & molded to suit customers specific requirements.
Conversion of metal, fiber glass, wooden parts - to integrated plastic Parts.
Conversion of multiple parts and components-into single rotomolded unit.
