PVC Plastisol Compound have typically been considered as 100% solids. At a temperature of 60ºC to 82ºC, depending upon the gel rate of the plastisol, solvation of the solid resin by the liquid plasticizers occurs, causing the plastisol to deposit on the preheated metal. The viscosity of the plastisol increases gradually with aging. This is especially true if the aging plastisol is subjected to elevated temperatures, such as might be encountered in hot storage areas or dip tanks that tend to increase in temperature during use. Plastisol can be thinned by using special reducers The supplier should be consulted before thinning, as each material has a practical limit on its usage level.

With a given plastisol coating thickness is increased by:
Increasing the pre-heat temperature of the part, and Increasing immersion (dip) time (when heat is completely transferred from the part, this ceases to be a factor).
The coating is properly fused when the plastisol and adjacent metal surface reaches
optimum fusion temperature. For most compounds this temperature is about 180 degree. A thin coating over a thin piece of metal can be fused in just a few minutes, whereas, a thick coating over a massive piece of metal may take up to an hour.
It is important that the pre-heat and fusion ovens have relatively uniform temperatures in all areas of the oven. As the consistency of both coating thickness and proper fusion will be affected. With a lack of oven temperature uniformity, it is possible to degrade the plastisol in hot areas without proper fusion in cold areas.
Degradation occurs with excessive fusion. Degradation is evidenced by discoloration, with the color shift generally starting with yellow, subsequently changing to brown and then black. Continued excessive heat exposure, or over-fusion, will result in full degradation of the polymer with eventual liberation of hydrogen chloride (HCI) and blistering. Occurrence time and temperature depend upon the compound, plastisol, metal mass, and oven conditions.

Dip molding refers to the process of dipping a solid male mold, or mandrel, gelling a plastisol layer, fusing the gelled plastisol and then stripping the hollow parts.
Applications:
Electroplating Jigs
Hand Tools
Footwear
Textiles Screen Printing
Dip moulding products
Method:
Preheating:
Tools or parts must reside in the preheat oven long enough to absorb adequate heat for the dip process. This is largely determined by trail and error and is effected by plastisol thickness requirements, tool material (alloy), oven heating characteristics, and number of preheat stations. On very heavy tools or parts, this part of the process can easily be the most time demanding of the entire process and would ultimately control overall cycle time. This is overcome by adding more preheat sections to the machine design when it is known that large, heavy parts will be processed
Dipping
At this stage Pre Heated mould is dipped in liquid plastisol .Time of dipping depends upon the thickness required
Curing (fusing)
Dipped tools or parts must reside in the cure oven long enough to properly cure the plastisol. Time and temperature requirements are sometimes determined by trial and error and are effected by plastisol thickness, tool material (alloy), oven heating characteristics, and number of cure stations. On very large tools or parts with heavy coatings, this part of the process can be the most time demanding of the entire process and would ultimately control overall cycle time. Most plastisols require a 180 degree to cure or fuse. This varies with different formulations Over curing parts can also cause the plastisol to become too liquid and drip. Proper curing is usually verified by visual inspection and tear testing
Cooling
There are basically 3 ways to cool parts that have been dip molded or coated; forced air, ambient air, and water quench
Water cooling is the most efficient means, but is restricted in most medical applications. Forced air cooling is usually accomplished by fans operating on a timed circuit. The operator programs the fan on time to turn the fans off before cooling the parts too much. Too much cooling can make a mandrel dipped part difficult to remove from the mould. Under cooling can cause the part to distort when being stripped and can be a safety hazard if the parts are to be handled immediately after being striped (ejected).
The cooling process can be the “bottleneck” of the operation when processing heavy parts, thick coatings, or double dipped parts. The plastisol coating actually insulated the tool or mandrel and holds the heat in the metal longer. Thicker parts or double dipped parts (especially when using foams) increase the insulation properties making it more difficult to cool the tooling. In this case, more than one cooling station can be incorporated in the machine design when it is known that this type process is needed.
