Stack Molding For Plastic Injection Molding

Stack molds are the most amazing production tools available anywhere. The engineering and craftsmanship which goes right into a stack mold is actually a marvel.

For your layman, who has never built a plastic injection mold, it could seem like a huge, fancy piece of machinery which causes plastic widgets. Yet, through the perspective of an plastics mold maker, stack molds represent a very advanced of expertise.

What is a stack mold?

There are several variations on the party theme of stack molds, however, many common features are:

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

Basically, a stack mold has a stationary "A" half, and a minimum of two "B", or moveable halves. These are similar to the rotary molds that have been being used for many years, but they are vertical as an alternative to horizontal.

This means that the moveable cores rotate with regards to a vertical axis, instead of a horizontal. Also, the stack mold is extremely compact and contains a much smaller footprint.

Are stack molds expensive?

Yes, stack molds are quite expensive. That's the reason an increased volume is required to justify their expense. However, particularly in medical or cosmetic molding, the ROI is quickly realized.

Thinking about the considerable amount of engineering and mold making involved, the expenses is understandable. Designing and building a stack mold is just not for novices, or mold makers who go cheap! Plastic injection molding is difficult, and stack molding is on an entirely new level.

Do you know the applications for stack molds?

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

Increasingly more products are being designed to use soft overmolding, like toothbrushes or hairbrushes. These are perfect applications for stack molding.For the reason that part is injection molded, ovemolded, cooled and ejected in sequential cycles, production costs can be minimized.

Do you know the benefits of stack molding?

Stack molds can be purchased in numerous configurations to satisfy many different molding demands. Stack molding has an economical and efficient manufacturing solution to the manufacture of multiple plastic parts. Injection molding information mill always searching for extremely effective means of molding, but for the right

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

 Decreases quantity 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 prices are divided by each of the parts produced

 Producing the back and front elements of a key fob at the same time is a good example of the application for stack molding

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