Rotomizing process 

The Four Principal Stages of Rotational Moulding
  

  Rotoplastic molding, also known as rotary molding, is to load a quantitative powder resin into a cold mold. The mold is driven by a rolling machine to rotate and rotate slowly around two vertical rotating axes, while the mold is heated by an external heat source, so that the resin powder is melted and evenly coated on the surface of the entire mold cavity with its own gravity. Finally, the method of hollow product is obtained after cooling and demoulding. Compared with the extrusion, injection molding and blow molding processes often used in plastic molding, the rotoplastic process is more suitable for the production of large and medium-sized or complex plastic products, and the product has almost no internal stress and other advantages.

Rotational molding process characteristics 

1. Low cost of rolling short mold: For products with the same specifications and sizes, the cost of rotoplastic mold is much lower than that of blow molding and injection molding.

2. The edge strength of rotoplastic products is good, and the thickness of the edge of the products is thicker. Solve the problem of thin edges of products in the middle room

3, rotomolding can be placed in various inlay

4, the shape of rotomolding products can be complex

5, Rotomolding products can be produced fully closed products

6, rotomolding products can be filled with foam materials to achieve insulation

7, no need to adjust the mold, the wall thickness of rotomolding products can be freely adjusted

 Rotomized material

  Linear low density polyethylene (LDPE)resin is called the third generation polyethylene.In addition to the properties of general
polyolefin resins, its tensile strength, tearstrength, environmental stress crack resistance,low temperature resistance, heat resistance The performance and puncture resistance areparticularly superior.

  The characteristics of polyurethane foam itself: light weight, heat insulation, heatpreservation, waterproof, fire and corrosion resistance, abrasion resistance, oil resistance, fatigue resistance, vibration resistance andstrong adhesion.

 

Shell material

In addition to the properties of general polyolefin resins, its tensile strength, tear strength, environmental stress crack resistance, low temperature resistance, heat resistance The performance and puncture resistance are particularly superior.

Inner filler

The characteristics of polyurethane foam itself: light weight, heat insulation, heat preservation, waterproof, fire and corrosion resistance, abrasion resistance, oil resistance, fatigue resistance, vibration resistance and strong adhesion.

Rotational molding is to first add plastic raw materials into the mold, and then the mold is continuously rotated along two vertical axes and heated, so that the plastic raw materials in the mold are gradually uniformly coated and melted and adhered to the mold under the action of gravity and thermal energy. The entire surface of the cavity is formed into the desired shape, then cooled to shape, demolded, and finally the product is obtained.

Product  Installation

Put any piece of floating body arc face down and put the HDPE pipe on the floating body. Then take any piece of floating body and buckle it on the pipe. Fix it with gaskets and bolts.  Align the flange hole of the rubber hose with that of the HDPE pipe, pass the bolt through the flange hole, and tighten the nut to fix it.
