After the dip moulding process is completed, quality control is carried out to ensure the vinyl products are finished. The products durability is then tested by bending and pulling the caps and plugs to see if they crack. If there are no cracks, one or more finishing processes will be performed.

Punching holes

Punching is used to make openings in the product, this is done with both a hand punch and a hydraulic punching machine. The hand punch can create holes for the passage of electrical cables such as television cables, which the machine cannot accomplish. A hole is punched by hand and the excess plastisol is removed.

Some caps require a ventilation hole; these vinyl caps are pressed onto a nail mat with a mould, which created these holes. The bolt holes of springs (e.g. shock absorbers under a machine) are also punched. Dipping puts vinyl plastisol in the holes. A hydraulic punching machine pushes a bolt where it needs to be, which loosens the plastisol and allows it to be removed.

Punching out recesses

This is done to remove certain parts from a dip-moulded product. This is important, for example, to ensure that the dip-moulded product can attach to the end product. Cut-outs can be punched in all kinds of shapes, such as rectangles, triangles, o-shapes to w-shapes and slots.

For some parts, a fitting mould is used for this, for example for a fire brigade cutter. For other parts, the finishing points are incorporated into the dipping mould, making it easy to identify the cut-out locations immediately after the dipping process.

Other treatments

In the vinyl coating of springs, there may be air bubbles in the plastisol coating. To ensure that the metal is no longer exposed, these points are repaired. These defects are fixed by applying plastisol, which is then heated to 300 degrees so that it curves. Vinyl caps can also be used as sleeves, for example, to protect posts. To make these protective sleeves, the back of the vinyl cap is cut off on a lathe.

Customised packaging and assembly

The vinyl products are packed into bags of 100 pieces using a counting scale. Each customer can specify how they want their products packed. Boxes are available in 5 sizes. But it is also possible to receive the caps or plugs in a supplied crate or pallet. If required, we can also arrange the logistics process, where we ship your orders directly to your customers on disposable pallets. This saves you time and costs.
