NAROTO MACHINES AND MOULDS

• N.A.Roto Machines  Moulds India has completed
  three successful decades in the rotomoulding
  industry, acquiring an unparalleled position. The
  company was initiated in 1982 with manufacturing
  of moulds for rotomoulding tanks. Shortly, it
  stepped into an advanced arena, wherein, it
  started developing Rotational Moulding Machines
  along with ancillary equipments
  like Pulveriser, Mixer, Extruder, Scrap
  Grinder and Mild steel Stainless steel moulds
  under the brand NAROTO. These equipments were
  innovative, and were of impeccable quality, which
  accelerated the brand on the path of success,
  ahead of its contemporaries.
• Our customer centric attitude to develop
  customized products, years of industry wisdom and
  technical expertise, dedicated skilled and
  professional staff, total turnkey solution has
  stamped us with a hallmark of trust and integrity.

  manufacturing unit located in GIDC, Vatva,
  Ahmedabad enjoys the privileges of Most Developed
  Industrial Zone and has a convenient atmosphere
  for plastic, chemical and pharmaceutical
  industries to flourish.
• At present our operations are active across five
  continents and 87 countries, making us a global
  player in rotomoulding industry. The company has
  ISO 9001 2015 Certification verifying the
  stringent quality test that we perform on our
  products to get the best end result. We plan to
  expand further with constant improvisation and
  upgradation on technological front, but with same
  values and ethics, which has been our strength
  for so long

ABOUT ROTOMOULDING

• In Plastic Industries, three main processes are
  known to the industries (1) Extrusion (2) Blow
  Moulding (3) Injection Moulding.
• In all these processes, the main drawback is the
  high tooling or die cost of the equipments
  against the single piece weight of the product.
  For the large Hollow Component the Rotational
  Moulding is most economical process. The basic
  advantages of the process are as below.

5
ADVANTAGES OF PROCESS

• Economic tooling costs.
• Single piece construction.
• Weight reduction as compared to most Processes.
• Uniform wall thickness.
• Variety of finishes and colours.
• The ability to produce multi-wall Mouldings.
• Metal inserts as integral parts.

6
ADVANTAGES OF PROCESS

• Short lead-time.
• Minor undercuts are possible with no draft angle
  required.
• Products from this process can offer excellent
  load-bearing and resistance to stress cracking
  and corrosion.
• Low maintenance.
• Ease of Operation.

7
PROCESS

• Rotational Moulding, also called Roto Casting
  or Roto Moulding is a unique process because the
  heating, shaping and cooling process take place
  inside a mould with no application of pressure.
  The process is carried out at the ambient
  pressure, which makes the products withstand
  environmental stress and crack resistant during
  use.
• A predetermined quantity of blended polyethylene
  resin powder is poured inside a cold mould
  (usually of aluminum or steel sheet metal).

8
PROCESS

• The mould is then rotated (Bi Axially) and
  gradually heated inside the oven. As the metal
  mould gets heated, the polymer resin powder melts
  and the molten resin eventually get distributed
  (Coated) along the inner surface of the mould.
  When all the powder has melted distributed, the
  mould is transferred to a cooling chamber keeping
  the mould rotating.
• The Bi-Axial rotation is continued until the
  cooling process is finished and the polyethylene
  has solidified. The mould is then opened and the
  finished product is removed. Given process chart
  helps understand the system.

RAW MATERIALS

• LLDPE / MDPE / HDPE (Roto Moulding Grade).
• MFI Between 3.0 to 4.5 and Density.
• Between 0.92 to 0.95 are widely used.
