Stack molds are among the most amazing production tools can be found anywhere. The engineering and craftsmanship which goes in to a stack mold is truly a marvel.

For that layman, who may never have built a plastic injection mold, it could seem like a major, fancy bit of machinery that produces plastic widgets. Yet, from your outlook during an plastics mold maker, stack molds represent a very advanced of expertise.


Just what is a stack mold?

There are numerous variations on the party's theme of stack molds, but some common features are:

 Built for very high production runs
 Have single cavity and multiple cores
 Use indexable cores to injection mold multi-materials
 Have to be able to do multiple operations from the molding cycle

Basically, a stack mold includes a stationary "A" half, and a minimum of two "B", or moveable halves. They're exactly like the rotary molds that have been in use for several years, however are vertical instead of horizontal.

Which means that the moveable cores rotate in regards to a vertical axis, as opposed to a horizontal. Also, the stack mold is quite compact and has a much smaller footprint.

Are stack molds expensive?

Yes, stack molds can be expensive. That is why an increased volume is required to justify their expense. However, especially in medical or cosmetic molding, the ROI is quickly realized.

Taking into consideration the considerable amount of engineering and mold making involved, the cost is understandable. Designing and developing a stack mold is not for beginners, or mold makers who cut corners! Plastic injection molding is difficult, and stack molding is by using an entirely new level.

Which are the applications for stack molds?

Because they are for high production products, the normal applications are suitable for cosmetics and consumables, including deodorant or toothpaste containers. Automotive and medical goods are also frequently produced using stack molds.

A growing number of goods are being who use soft overmolding, like toothbrushes or hairbrushes. They are perfect applications for stack molding.Since the part is injection molded, ovemolded, cooled and ejected in sequential cycles, production costs may be minimized.

Which are the advantages of stack molding?

Stack molds can be purchased in numerous configurations to fulfill a variety of molding demands. Stack molding gives an economical and efficient manufacturing solution for the production of multiple plastic parts. Injection molding organizations are always seeking better means of molding, but for the right

A few of the together with your stack molding process include: Increased output efficiency (productivity)

 Decreases amount of machines required

 Lower machine size requirement vs.. multi-cavity single face molds

 Produce twice as many parts without increasing press size or clamp tonnage, which greatly reduces part costs

 Set-up some time and run-time cost is divided by each of the parts produced

 Producing the back and front areas of a vital fob as well is a great one of your application for stack molding

 Mold ejection functions are self-contained, no additional labor or steps required
