Dip Molding

Inside the dip molding process, the molds are dipped in a polymer in order to mold a part. Consequently, you can create grips, caps, drink coolers as well as a number of other items. The process starts off with aluminum or steel molds. The rack is dipped in a fix of mold release to strip a finished part. Over the following phase, the part is preheated. Let's find out.

Materials found in the procedure

Usually, plastisol is employed for dip molding. However, other materials, including neoprene, latex and urethane may also be popular.

Set-up time

A couple of years back, level sensing has not been used for vinyl displacement. So, many test frames were performed to find the correct part length. Nowadays, the technological advancements make it possible to dip the correct length effortlessly.

Heat forms for the molding process

In line with the part configuration, the preheat is made through the very fast convection air. In other words, the infrared is coupled with convection air for implementing rapid heat with the infrared to the process.

Wall thickness

Uniformly preheated parts ensure that you get consistent wall gauge. To guarantee consistency, temperature level is maintained for each cycle. Since they use high quality ovens, part quality or system performance isn't getting affected even if the over doors are open.

Dip tanks and cooling

In most cases, there's no need to cool the tanks. Old system had poorly insulated ovens that leaked heat. Therefore, the tanks should be refrigerated. Really should be fact, tank cooling is not required for virtually all MCT machines.

Exhaust smoke

Since the process doesn't produce any smoke or fumes, you don't need a dip station exhaust. The reason is that the task does not require high pre-heat temperatures. However, if the mold gets into the plastisol, you will see a little waft of smoke.

Additional filters

Mostly, you don't need additional filters. Since process involves high speed convection, no smoke is produced. Therefore, you do not need any filters to handle the exhaust.

Quench water

There's no need to treat the quench water as being a recirculation system is more than enough. Moreover, cold water can boost cooling keeping the temperature of the quench water.

Scrap Amount

You'll not expect any scrap. The rejection rate is below 3%, that may give you a great concept of how efficient the complete method is.

Safety measures

In an MCT system, you've got a lot of safety features, like emergency stop buttons, pause/resume buttons, safety fencing and other standards.

Raw material costs

The fabric costs may be lessen through ordering, formulation and efficiency. As a way to decrease the cost via formulation, you need to use extenders or fillers, that will extend your raw material. In addition to this, may other methods are using for reducing the raw material costs significantly.

So, this is a brief article describing the basic principles from the dip molding process. Hopefully, you will find this informative guide helpful.
