Stack Molding For Plastic Injection Molding

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

For that layman, who has never built a plastic injection mold, it may appear to be a big, fancy bit of machinery that produces plastic widgets. Yet, from the outlook during an plastics mold maker, stack molds represent a very advanced of knowledge.

Just what is a stack mold?

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

Built for quite high production runs
Have a single cavity and multiple cores
Use indexable cores to injection mold multi-materials
Have to be able 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. They’re like the rotary molds that have been being used for quite some time, but they are vertical instead of horizontal.

This means that the moveable cores rotate with regards to a vertical axis, rather than horizontal. Also, the stack mold is extremely compact and possesses a significantly smaller footprint.

Are stack molds expensive?

Yes, stack molds may be expensive. This is why an increased volume is needed to justify their expense. However, specifically in medical or cosmetic molding, the ROI is easily realized.

Thinking about the tremendous amount of engineering and mold making involved, the expense is understandable. Designing and creating a stack mold just isn’t for beginners, or mold makers who go cheap! Plastic injection molding is hard, and stack molding is by using an entirely new level.

What are applications for stack molds?

Since they’re for high production products, the common applications are suitable for cosmetics and consumables, like deodorant or toothpaste containers. Automotive and medical products are also frequently produced using stack molds.

More and more items are being desinged to use soft overmolding, including toothbrushes or hairbrushes. These are generally perfect applications for stack molding.As the part is injection molded, ovemolded, cooled and ejected in sequential cycles, production costs may be minimized.

Which are the important things about stack molding?

Stack molds can be purchased in numerous configurations to satisfy many different molding demands. Stack molding provides an economical and efficient manufacturing solution for the creation of multiple plastic parts. Injection molding companies are always searching for more effective strategy for 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 time and run-time prices are divided by every one of the parts produced

Producing the front and back areas of an important fob at the same time is a useful one of your application for stack molding

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