Stack molds are a few of the most wonderful production tools available everywhere. The technology and workmanship that goes to a heap mold is really a marvel.
For the layman, that hasn’t constructed a plastic Rotational mold, it may resemble a large, fancy bit of machinery which creates plastic widgets. However, from the point of view of a Rotomolding Process , stack molds signify a quite large degree of experience.
What’s a heap mold?
There Are Many variations on the subject of pile molds, but a few common characteristics are:
Have the ability to perform multiple operations in the casting cycle
Basically, a heap mold includes a static “A” half, and at least 2 “B”, or moveable halves. They are much like the inkjet molds which have been used for several years, but are vertical instead of horizontal.
This means that the moveable cores rotate around a vertical axis, as opposed to a flat. In addition, the heap mold is quite compact and contains a much smaller footprint.
Are stack molds pricey?
Yes, stack molds are rather pricey. That’s the reason why a high quantity is needed to justify their cost. But, especially in plastic or medical molding, the ROI is soon realized.
Considering the tremendous amount of technology and mold making entailed, the cost is understandable. Designing and constructing a pile mold isn’t for novices, or mold makers who cut corners! Plastic Rotational molding isn’t simple, and pile molding is on a totally new level.
What are the applications for stack molds?
Since they’re for top production products, the typical applications are for plastics and consumables, such as deodorant or toothpaste boxes. Automotive and healthcare products are also often made using heap molds.
More and more products are being designed to utilize soft Rotomolding Process, like toothbrushes or hairbrushes. These are ideal applications for pile molding. Because the part is Rotational molded, ovemolded, cooled and ejected in consecutive cycles, production costs could be lessened.
