8 Methods for Adding Color
9 Colors The two basic methods of coloring material for the rotational molding process are dry blending and color compounding. Both systems have their advantages and disadvantages, and some molders specify one system above the other or even use both methods depending on the end application.
10 Dry Blending One big disadvantage of this method is pigment migration. It is particularly relevant with high loadings of pigment. Clearly this may have influence on any food contact approval or toy manufacture, mold surfaces can be stained and covered with pigment, handling may cause wipe off, and contamination can occur if the mold is being used for different colors. Mixing is critical because it is thought that part failures are caused by agglomerates or pigment clusters which act as stress failure points.
11 Compounding Color compounds are made by hot melting the color pigment into the base polymer via an extruder creating MicroPellets or standard pellets The standard colored pellets are then ground where they are reduced to powder. This type of coloring gives the best possible dispersion, and uses the lowest amount of pigment. For these reasons the properties of the base polymer are retained and may even be improved. In some cases it is also possible to achieve brighter colors, and more opaque colors, since greater loading levels are achievable without loss in properties. It is also clear that as the pigment is encapsulated within the base polymer, no amount of rotation and tumbling during the rotomolding process, will remove the pigment. Hence moldings using this method are consistent, with no pigment migration to the surface.
12 Comparison Compounds Expensive No deterioration to PE properties Low levels of pigment added Cost Color repetative Potential for long delivery times Good color hold and no wipe off Enhanced UV stability Not messy, no mixing No real issues of moldability Better control on uniform wall thickness Able to generate textures, gloss or matt better Can improve release action Dry blends Very dirty process Cheap and make just in time Need to hold pigment stock Pigment wipe off During molding After molding (toys) Typically use powder form Poor technical performance Quality of the pigment supplied Unreliable color Pigment swirl or bad flow issues Labor intensive process
13 Grinding the Pellets
14 Grinding the Pellets The standard industry norm of supplied polyethylene powder is based on a 500µm maximum with most of the particles being at 290 to 300µm. This is achieved by the use of a mill which is basically a combination of a cutting system and a series of sieves. The aim of the process is to generate a consistent powder to a set specification where variables, which can affect the molding process, are controlled. The main variables are the size of the powder, the particle size distribution, the bulking behavior of the powder, the shape of the particles, and the flowability or pourability of the powder.
15 Grinding the Pellets Rotational Moulding : grinding process Schematic Cyclone Dust collect Granules over size Sieves Grinding head Powder collect Package Normal specification : particle size distribution pourability bulk density particle shape (!)
16 Grinding the Pellets The operation of size reduction is not seen as grinding or milling but more like high speed cutting. In general terms, the granules are fed into a chamber, where there are two sets of plates. One of these is typically rotating and the other fixed. They have a series of teeth or cutting edges, and are situated such that the gap between them gets closer at certain regions. So, as the granule moves through the plates it is cut and reduced in size. The reduced in size granules, i.e. powder, is released at the edge of the plates. Released powder is then fed on an air current to a series of sieves which sorts and select the particles of a certain size. Those particles which are oversize are returned to the cutting plates where they go through the system again.
17 Grinding Powder Clearly this process is one which generates a lot of heat as the temperature rises within the cutting environment, the polyethylene particles will soften. This in turn makes any cutting cleaner and more sharp rather than tear or shear when the polymer is cold. However, this temperature must be controlled, because if the polymer softens too much then the mill will block where the molten particles stick and adhere to each other forming a large molten mass, and hence no new granules will be able to enter the grinding chamber. Thus the skill of the mill operator is to run in that very narrow window between where the particles are torn or shredded, and where the mill blocks due to the particles sticking and adhering together.
18 Test Equipment Rotational Moulding : powder quality Dry flow test Standard weight of powder placed in funnel. Time taken to flow through standard orifice measured. ISO 6186 ASTM D1895 Rotational Moulding : powder quality Bulk density test Powder allowed to flow into cup. Remove excess powder. Weigh. Bulk density = powder weight volume ASTM D1895
19 Powder Shape Hairy particles can stop even flow of powder in process Bridging can occur where hairy particles can not flow into narrow spaces, as they lock together and melt. If particles are too hairy they adhere together and create voids. These voids are seen on sharp corners or radii. Physical properties (such as impact, tensile strength and elongation) can be weakened with bubbles, bridging and voids. Increased process conditions may overcome bubbles but will result in thermal degradation. Fibrous particles can combine into fluffy balls rolling about on the inner surface of the powder, resulting in irregular shaped eggs or lumps.
20 Grinding Unit
21 Disadvantages The extra grinding stage of reducing a granule to a processable form is a cost Quality control of powder is important as powder variables can alter process requirements Each grade or polyethylene type requires specific conditions Powder transfer can be dangerous, build up can cause dust explosions and fire Extra stabilization may be required in the polymer as an extra process step is being incorporated, hence resulting as a more expensive polymer Extra equipment purchase is necessary Grinding units, mills, must be regularly checked as blunt cutters will alter powder made
22 Powder Characteristics
23 Disadvantages Risk of contamination If there is a change in the PSD curve, the melting characteristics of the powder will be different Powder which is hairy will mold differently than a smoother powder It is very easy for a molding to be under cooked or over cooked if quality procedures are not maintained Hairy particles can form clumps which do not melt in a uniform way Pigment swirling may be an issue with dry blend colors Powder flow into some designs, sharp corners, etc may be an issue Powder by its very nature may mean that packing into a certain mold design may be a problem Powder needs space in a mold in order to tumble and distribute itself

51 Benefits of using MicroPellets Cleaner virtually no dust Compounding (eg. Coloring) and MicroPelletizing can be achieved in a single step Micropellets have a better packing density than powder. Improved flow characteristics: Fills hard to reach areas in complex molds. Enables more uniform inner layers. Consistent lay-down and cook times.
52 Benefits of using MicroPellets Enhanced part detail definition (threads, logos, lettering) Better impact results are typically reported. Segregation of Powder in the container Possibility of improved process conditions: Lower temperatures Reduced cycle times Slower rotation speeds Faster mold charging Uniform wall thickness, giving potential of shot weight reduction.
