From the dip molding process, the molds are dipped in a polymer in order to mold an important part. As a result, you can create grips, caps, drink coolers along with a variety of other items. The process begins with steel or aluminum molds. The rack is dipped in a fix of mold release to strip a finished part. Within the next phase, the part is preheated. Let's find out more.
Materials used in the process
Usually, plastisol is employed for dip molding. However, many other materials, including neoprene, latex and urethane are also very popular.
Set-up time
A couple of years back, level sensing had not been utilized for vinyl displacement. So, many test frames were performed to find the correct part length. Nowadays, the technological advancements make it simple to dip the right length with ease.
Heat forms for your molding process
Depending on the part configuration, the preheat is actually created over the broadband convection air. In other words, the infrared is coupled with convection air for implementing the quick heat from the infrared for the process.
Wall thickness
Uniformly preheated parts make sure that you get consistent wall gauge. To make sure consistency, temperature level is maintained for every cycle. Because they use excellent ovens, part quality or system performance doesn't affected set up over doors are open.
Dip tanks and cooling
As a general rule, you should not cool the tanks. Old system had poorly insulated ovens that leaked heat. Therefore, the tanks must be cooled off. Really should be fact, tank cooling just isn't required for the majority of MCT machines.
Exhaust smoke
Since process doesn't produce any smoke or fumes, you do not need a dip station exhaust. This is because the process does not require high pre-heat temperatures. However, once the mold gets into the plastisol, you can observe a smaller waft of smoke.
Additional filters
Mostly, you do not need additional filters. Since the process involves very fast convection, no smoke is produced. Therefore, you do not need any filters to deal with the exhaust.
Quench water
You don't have to treat the quench water as being a recirculation product is ample. Moreover, cold water can boost cooling keeping the temperature with the quench water.
Scrap Amount
You won't expect any scrap. The rejection rates are below 3%, which can give you a great thought of how efficient the whole method is.
Precautionary features
In the MCT system, there is a lot of security features, for example emergency stop buttons, pause/resume buttons, safety fencing as well as other standards.
Raw material costs
The pad costs may be reduce through ordering, formulation and efficiency. So that you can reduce the cost via formulation, you may use extenders or fillers, that may extend your raw material. Aside from this, may other methods are using for minimizing the raw material costs significantly.
So, this became a quick article describing the basic principles of the dip molding process. Hopefully, you will discover the guide helpful.
