Dip moulding is among the earliest forms of plastic moulding and has been in continual use since the early 1950′s. It is used to make various plastic parts and pieces. The process of dip moulding has undergone a lot of modifications through the decades so the parts that have been dip moulded are of high quality. The products created through this process are very competitive in the market in terms of durability, design and cost.
Dip moulding is a process that is used in the plastic manufacturing industry. To make the plastic parts through this process, metal moulds are heated at the right temperatures and then goes through the dipping or immersion process in a large tank that is filled with liquid vinyl plastisol. The metal mould is hot while the plastisol is cool. The heat from the metal mould gels the plastisol in contact with the mould and the time that the mould is allowed to dwell determines the wall thickness of the finished moulded component.
The next step in the process is the removal of the moulds from the plastisol. Once they are removed, the gelled plastisol around the mould is cured by undergoing a baking process. After the curing process, the finished plastic parts are taken off the mould. The plastic parts are now ready for any final touches or if there are none then they can be prepared for shipment.
Through the years, a lot of improvements have been made to the process of dip moulding. In the past, the plastic parts that were produced only had a smooth and shiny surface. Today, plastic parts can be made in various textures and finishes. They are now able to produce parts with matte finish, foam or textured finish. This is mainly due to the improvements in the formulation of the plastisol.
Dip moulding is highly favoured in the industry of plastic manufacturing of vinyl components because of its many advantages. A few of its best advantages are that it is a process that has lower tooling costs and shorter lead times In the plastic industry, manufacturers are always looking for ways to speed up the manufacturing process and lower the cost. This is why dip moulding is a favoured manufacturing process in the plastic industry.
Also Read The dipping process used for moulding can also be used to apply a permanent coating of PVC to your product. Depending upon the substrate thickness a fairly thick seamless coating can be applied in whole or part in order to protect and cushion or just enhance.
