Aluminum Custom Rotational Mold

Advantages
 1). The cost of plastic rotational mould is low.
 2).The edge of rotational moulding products can reach more than 5mm
 3).variety of inserts can be placed to rotational mould.
 4).The shape of rotational moulding products can be very complex
 5).Rotational moulding products can be produced fully closed.
 6).Rotational moulding products can be filled with foam material, to achieve thermal insulation.
 7).No need to adjust the mould, the thickness of rotational moulding products can be adjusted.
8).It's available to deal with a variety of surface patterns and produce products in various colors.
Our Services
 We offer 3d design, opening mould, and rotational products manufacturing.
1. Design & Engineering Services
a. We can help you modify your original 3D drawing to make it suitable for rotational molding.
b. For new project,our in-house Design & Engineering Department will help advise and manage your
project all the way to a produced rototmolded part. 
c. Sample canning and designing.
2. Rotational Molding Design Guides 
a. Minimum wall separation 5x wall thickness (a)
b. Minimum wall separation 3x wall thickness (b)
c.Uniform wall thickness ± 20% (c)
d.±10% is considered precise tolerance (c)
e. Wall thickness .090" to 1.00" (c)
f.Different wall thickness can be produced based on functional requirements
g. Large flat areas need a crown or ribs (d)
h. Corners need minimum radius of 3/16"(e)
i.Structural strength
· Reinforcing ribs - average proportions
· Height 4x wall thickness (f)
· Width 5x wall thickness (g)
·Kiss-off ribbing (h)
· Part Finishing and Secondary Operations
Note: Design Guide information is based on Linear Low Density Polyethylene (LLDPE) other
materials tolerance can vary.
3. Cast Tooling Pattern
When your design is finalized the pattern production begins. Most commonly patterns are CNC
machined from the 3D model, but other options are available.
After the pattern is reviewed and signed-off on, the followers for determining the parting lines are
constructed. Next, the pattern goes through the sand ramming process creating the cope and drag.
Then our Tooling Department is ready to pour the tool.
4.Rotational Molding Plastic Parts
we can also provide production for plastic parts by rotational molding.
 
What is Rotational Molding?
Rotational moud or Roto Molding which is a high temperature, low volume, low pressure thermoplastic
forming process .It mainly suite for producing hollow, one piece parts such as large oil or chemical
tanks, kayaks, point of purchase displays, frames, cases, furniture,
carts, dispensers, park equipment. The material can be UV resistant which can ensure the outdoor
use of your products .
