Processing Method

DIP

Hollow bodies can be manufactured by dipping, a process that can also be used to coat fabric previously set in determined shapes (gloves), flasks and domestic utensils.

Dip molding: this method consists of dipping a 100-103 oC pre-heated mold (in metal, ceramic or glass) in plastisol for a short period and gelate the layer of paste deposited in its surface.

Hot dip coating: this method allows the coating of objects such as soap dish, drip rack, tweezers, hooks, glass flasks, to protect them against corrosion or to improve appearance. The object to be coated is pre-heated before dipping.

Cold dip coating: this technique is used mainly for glove manufacturing with or without fabric support. The glove with fabric is put in a cold mould with the shape of a hand, and afterwards is dipped in plastisol. After the paste excess has dripped off, the mould is introduced in a gelation oven.

This process is specifically the most adaptable to PVC resins for plastisols (obtained by emulsion and micro-suspension polymerization process), but dry blends in powdered PVC suspension can also be used for specific requirements.
